That gap, between the number of reactors that have stopped generating power and the number whose sites have been fully remediated, tells the central story of nuclear decommissioning. It is a decades-long, technically demanding, heavily regulated, and expensive process. The estimated global cost over the next four decades is approximately $500 billion.

Most organisations in the nuclear industry treat that figure as a liability. It sits on balance sheets, absorbs regulatory attention, and occupies the back pages of annual reports. The planning horizon for decommissioning is measured in generations, not business cycles. It does not attract the same commercial energy as new build.

That framing is understandable. It is also incomplete. Decommissioning is not only a liability. It is a market, large, complex, multi-decade, and structurally undersupplied with the advisory and commercial capability it needs to be executed well. The organisations that recognise this distinction early are positioning themselves ahead of a significant structural opportunity.

The scale of what is coming

The global nuclear decommissioning services market was valued at approximately $9.5 billion in 2025 and is projected to grow at a compound annual rate of between four and six per cent through 2034, reaching $19 billion then. These figures reflect only the near-term services market, the contracting, engineering, waste management, and project management work currently under procurement. They do not capture the full long-term value of the decommissioning pipeline, nor the advisory, commercial structuring, and workforce planning work that enables it.

The market’s geographic distribution is concentrated but shifting. Europe currently accounts for approximately 35 to 40 percent of global decommissioning revenues, driven by the UK’s legacy fleet managed by the Nuclear Decommissioning Authority and Germany’s post-Fukushima phase-out programme. The United States, with 41 permanently shut-down reactors the single largest national market. Asia, particularly Japan following Fukushima and South Korea’s ageing fleet, is an emerging decommissioning market of significant scale.

The UK provides the clearest illustration of both the magnitude and the complexity. The estimated cost of cleaning up the UK’s 17 civil nuclear sites managed by the NDA is £132 billion. The work is not expected to be completed for approximately 120 years. Sellafield alone, the largest nuclear site in Europe, has generated two major contracting packages in the last twelve months: a 15-year, £4.6 billion framework contract for high-hazard risk reduction work awarded in November 2025, and a further £2.9 billion in infrastructure support contracts awarded in October 2025.

A 15-year, £4.6 billion contract at a single site. That is not a liability management exercise. That is a market.

Why decommissioning has been treated as a problem, not an opportunity

The historical treatment of decommissioning as a cost to be managed rather than a market to be served reflects several structural features of how the nuclear industry developed.

Decommissioning funding was designed to be a regulatory obligation, not a commercial activity. In most jurisdictions, operators are required to set aside funds during the operating life of a reactor to cover future decommissioning costs. In the United States, combined nuclear decommissioning trust funds hold approximately $100 billion, with per-reactor cost estimates ranging from $280 million to $612 million. These funds are ring-fenced, regulated, and governed by strict rules about how they can be deployed. Regulatory framing and financial assurance, rather than commercial investment, have shaped how the industry thinks about the activity.

The timescales involved also work against commercial clarity. A reactor that shuts down today may not complete full site remediation for 40 to 80 years, depending on the strategy chosen. Operators must choose between immediate dismantling, a period of safe storage before dismantling, or long-term entombment, each with different cost, workforce, and regulatory profiles. The long duration compresses the incentive to plan strategically. Decisions taken today about site strategy, contracting approach, and workforce transition will define outcomes that no one currently in the room will see.

And the liability is real. In a transaction context, decommissioning obligations can represent a material, and frequently underestimated, component of asset value. In the UK, the Nuclear Liabilities Fund has seen estimated decommissioning costs nearly double since 2004. Across the global industry, the gap between pre-funded decommissioning reserves and total estimated obligations remains substantial. These are not theoretical risks. They are balance sheet exposures that affect credit ratings, transaction structures, and investor appetite.

Five components of the market

When decommissioning is approached as a market rather than a liability, five distinct commercial domains become visible. Each has its own supply chain, its own procurement logic, and its own set of organisations positioned to serve it.

• Strategy and programme planning. Before any physical work begins, an operator must make consequential decisions: which decommissioning strategy to adopt, how to sequence activities across a site or a fleet, how to structure the contracting model, and how to engage with regulators on the pathway to licence termination. These decisions have material cost consequences. An operator that optimises its decommissioning programme at the strategic level, rather than managing activities on a project-by-project basis, can significantly reduce total costs. Yet this is precisely the capability that is least well-served by the existing supply chain, which is predominantly oriented toward execution rather than planning.

• Engineering and dismantling contracting. The physical decommissioning work, reactor dismantling, contamination surveys, structural demolition, and site clearance, is delivered through large, long-duration contracts of the kind recently awarded at Sellafield. The market for these contracts is structurally oligopolistic: a small number of tier-one contractors have the nuclear-grade credentials, bonding capacity, and regulatory relationships to compete for major awards. The barriers to entry are high. The market opportunity for those inside the tier-one group is substantial.

• Radioactive waste management. Waste management is the most technically complex and commercially constrained element of decommissioning. The volume of radioactive material to be managed is large: at Sellafield alone, retrieving waste from legacy ponds and silos is a multi-decade programme requiring specialised robotics, remote handling systems, and processing capacity. Up to 90 percent of non-radioactive materials at a nuclear plant, metals, concrete, and process equipment, can be recycled and reused after clearance surveys, creating a secondary materials economy within the decommissioning process. The gap between waste arisings and available disposal routes remains a constraint in most jurisdictions, particularly for intermediate and high-level waste categories.

• Workforce planning and knowledge transfer. Decommissioning is a labour-intensive activity at a moment when the nuclear workforce is under structural pressure. Nearly 40 percent of the global nuclear workforce is expected to retire within the next decade. A March 2026 NSI report identified critical shortages in nuclear-qualified machinists, welders, inspectors, nondestructive examination specialists, and project managers, precisely the roles that decommissioning programmes require in volume. The workforce challenge in decommissioning is compounded by a knowledge transfer problem: the institutional memory of how a facility was built and operated, held by the people who built and operated it, must be captured before it is lost. This is not an HR function. It is a programme delivery risk.

• Site repurposing and community transition. What happens after a site is cleared is increasingly central to the planning and funding of decommissioning programmes. A decommissioned nuclear site is a piece of infrastructure, typically well-located, with existing grid connections, road access, and a history of managing complex industrial activities. The potential for reuse ranges from industrial parks to renewable energy installations to small modular reactor deployments. In Argentina, the Malargüe uranium processing complex, closed in 1986 and remediated over decades, was transformed into Parque El Mirador, a community green space co-designed with local residents. In the UK, Dounreay’s decommissioning programme has included comprehensive workforce retraining to stabilise the regional economy through the transition. The commercial question for site repurposing is not simply what the land is worth. It is who controls the planning process, how quickly regulatory oversight can be lifted, and whether the local authority and community have been engaged as partners rather than managed as stakeholders.

The five domains of decommissioning, strategy, contracting, waste, workforce, and site are each large enough to sustain a market. Together, they define a commercial ecosystem that the nuclear industry has only partially built.

What is structurally undersupplied

The physical execution capacity for nuclear decommissioning, from engineering contractors and specialist robotics companies to waste processing facilities, has developed significantly over the past two decades. Where the market remains thin is in the advisory and commercial structuring capability that enables programme owners to make better decisions about what to procure, how to sequence it, and how to structure the contracts through which they procure it.

Programme owners are often well-equipped to manage regulatory relationships and site operations. They are less consistently well-equipped to design and run sophisticated commercial procurement processes for multi-billion-pound, multi-decade programmes. The contracting models that best allocate risk between owner and contractor in a decommissioning context, where scope is uncertain, timescales are long, and cost estimation is inherently difficult, are not as well established as, say, contracts for new-build nuclear or offshore wind, which have become standardised through decades of transactional experience.

The workforce market also remains fragmented. The demand signal for decommissioning skills is growing, driven by the number of reactors entering the decommissioning process, the long duration of individual programmes, and competition for the same talent pool from new-build, life-extension, and advanced-reactor projects. But the planning and development of that workforce is rarely treated as a strategic function with its own investment logic. It is more often managed reactively, project by project, rather than as a sector-wide capability challenge requiring a coordinated response.

What the organisations doing it well are doing differently

The organisations capturing value in the decommissioning market share several characteristics that distinguish them from those that do not.

They plan at the programme level, not the project level. A utility managing a fleet of ageing reactors has more options available to it if it plans its decommissioning programme as a whole, sequencing sites, pooling procurement, standardising approaches, than if it treats each site as an independent problem. Fleet decommissioning programmes benefit from learning curve effects, shared contracting infrastructure, and the ability to develop and retain specialised workforce capability across multiple projects rather than building and dispersing it each time.

They invest in commercial structuring before contracting. The choice of contracting model whether to use target cost, fixed price, alliance, or framework arrangements has a larger impact on programme outcomes than most operators recognise at the point of procurement. The same physical scope, contracted differently, can produce radically different cost and schedule outcomes. Organisations that invest in commercial structuring expertise before they go to market are better positioned to design contracts that align contractor incentives with programme outcomes and that provide the flexibility needed to manage scope uncertainty over long delivery periods.

They treat site repurposing as a value driver, not an afterthought. Decommissioning costs can be substantially reduced when future site use is identified and planned early. A site being remediated to industrial brownfield standards rather than full greenfield has lower clean-up costs; a site with a credible reuse plan attracts stronger community engagement and reduced regulatory friction. The most effective decommissioning programmes embed site strategy from the outset, rather than treating it as something to be resolved after the technical work is done.

The window

The decommissioning market is in an early phase of maturation in some key countries. Even with Plant Life Extension, the volume of reactors entering the process will keep growing. The contract sizes are increasing. The regulatory frameworks governing decommissioning are, in most jurisdictions, evolving toward greater commercial sophistication in programme structuring and procurement. The workforce challenge is creating demand for new kinds of planning capability. And the question of what happens to nuclear sites after their operational lives is beginning to attract the attention of investors, local authorities, and energy planners who had not previously considered decommissioning their problem.

The organisations that will define the decommissioning market, as programme managers, commercial advisors, contracting specialists, and site developers, are making their moves now. The capital is beginning to follow. The supply chain is beginning to consolidate. The competitive positions that will matter in this market in 2035 are being established in 2025 and 2026.

$500 billion is a large number. What matters is who captures the value within it and how well they have prepared.

The post Decommissioning as a market appeared first on Damona | Strategy consulting | Nuclear industry.

The nuclear industry has spent the past decade focused on technology.

Reactor designs, safety systems, fuel types, modular construction methods, passive cooling architectures, the engineering conversation around Small Modular Reactors has become increasingly sophisticated and increasingly crowded. While over 80 SMR designs and concepts are currently under development worldwide, the commercial conversation has not kept pace.

How SMRs will actually be financed, contracted, deployed, and scaled remains one of the least resolved questions in the market today. That gap, between technological ambition and commercial architecture, is rapidly becoming the defining challenge of the sector.

The reality is straightforward: an SMR does not become economically transformative simply because it is smaller. It becomes transformative only if it can be deployed repeatedly, predictably, and at industrial scale.

And today, the market structure required to achieve that scale is still largely missing.

Why SMR economics work differently

The economic logic behind SMRs is frequently misunderstood.

Smaller reactors are not inherently cheaper on a per-megawatt basis. In many cases, first-of-a-kind SMRs are expected to be more expensive than large conventional reactors when measured against installed capacity.

What changes the equation is repetition.

The commercial promise of SMRs is built on the same industrial logic that transformed sectors such as commercial aviation and offshore wind: factory manufacturing, standardised designs, serial production, and learning curve effects generated across fleets rather than individual projects.

The OECD Nuclear Energy Agency has repeatedly highlighted this dynamic in its work on SMR deployment pathways. The competitiveness of SMRs depends fundamentally on volume. The difference between a first-of-a-kind unit and a fleet-deployed nth-of-a-kind reactor is not marginal but structural.

This has major implications for deployment strategy.

An SMR developed as a one-off infrastructure project, however technically credible, is unlikely to achieve the economics that justify the model in the first place. The commercial viability of SMRs depends on repeatability, manufacturing continuity, and deployment pipelines large enough to drive cost reductions over time.

The challenge is that current procurement and financing structures are still largely designed around traditional project-by-project nuclear development.

The NuScale lesson

The clearest illustration of this challenge remains the 2023 cancellation of NuScale’s Carbon Free Power Project in the United States.

The project was the most advanced SMR programme in the Western market and the first SMR design to receive approval from the US Nuclear Regulatory Commission. Technically, it represented a major milestone for the industry.

Commercially, it exposed the fragility of the current model.

The project had been structured around a subscriber framework in which a group of municipal utilities would collectively purchase electricity output under long-term agreements. As development costs increased, rising from initial estimates of approximately $5.3 billion to roughly $9.3 billion at the time of cancellation, participating utilities progressively withdrew from the project.

Ultimately, the issue was not reactor performance but cost absorption.

The commercial structure was unable to manage the uncertainty associated with the economics of first-of-a-kind deployment. By the time the project was cancelled, 23 of the original 35 subscriber utilities had exited.

The lesson was significant precisely because NuScale was one of the industry’s most mature programmes. It demonstrated that even a technically credible, regulatory-approved SMR can fail commercially if the deployment model does not adequately distribute FOAK risk.

The structural Catch-22

This reveals the central contradiction at the heart of the SMR market.

SMRs require scale to become economically competitive. But the conditions required to achieve that scale, lower costs, established supply chains, and proven operational performance, only emerge after scale already exists.

Every industrial technology faces some version of this problem. SMRs face it at nuclear scale.

The combination of high capital needs, long development timelines, and highly risk-sensitive customers creates a difficult commercial environment for early deployment. Utilities and governments generally prefer proven technologies with predictable cost structures. Yet the economics of SMRs improve only after repeated deployment has already taken place.

The result is a market where almost every stakeholder believes in the long-term potential, but relatively few are positioned to absorb the commercial premium associated with being first.

Without mechanisms capable of distributing that early-stage risk, deployment stalls precisely when commercial momentum is most important.

The commercial architecture is the real product

This is why the future of SMRs may depend less on reactor innovation alone and more on commercial architecture.

Fleet deployment models are central to this shift. Developers need deployment pipelines that span multiple units and sites, allowing manufacturing investment, supply chain development, and learning-curve efficiencies to compound over time. The economics of serial production cannot emerge from isolated procurement decisions.

At the same time, a new category of customer is beginning to reshape the market.

Large technology companies and hyperscalers are increasingly emerging as long-term nuclear counterparties, seeking stable, low-carbon electricity supply for data centres and digital infrastructure. Microsoft’s agreement linked to the restart of Three Mile Island and Amazon’s nuclear-related energy partnerships, and broader hyperscaler interest in advanced nuclear are important not only because of the electricity demand involved, but because they introduce highly creditworthy, long-duration customers capable of underwriting deployment risk in ways traditional utility procurement often cannot.

Government participation also remains essential.

The UK’s shift from the Contract for Difference model used for Hinkley Point C towards a RAB approach for Sizewell C reflects a broader recognition that financing structures matter as much as technology. By reducing financing costs and sharing construction risk more effectively, the RAB model seeks to address one of the fundamental barriers facing large-scale nuclear investment.

Similar mechanisms adapted to the realities of SMR deployment, including FOAK risk-sharing frameworks, revenue stabilisation mechanisms, and public-private financing partnerships, are likely to play a critical role in enabling early projects and building the foundations for future fleet deployment.

At the same time, supply chains themselves require forward visibility. Qualified manufacturers, specialised components, and skilled labour pools do not appear automatically once orders are signed. They require investment well in advance of demand. Without credible deployment pipelines, industrial capacity will remain constrained regardless of reactor readiness.

In other words, the challenge is no longer simply technological but also industrial and financial.

From engineering challenge to market design challenge

Political momentum around nuclear is clearly accelerating.

At COP28, 31 countries endorsed the goal of tripling nuclear capacity by 2050. SMR programmes are advancing across the United States, Canada, the United Kingdom, Central Europe, and the Gulf.

But political support alone does not create commercially viable deployment models.

The industry risks repeating a familiar pattern: developing technically credible reactors, attracting early-stage enthusiasm, and then struggling at the point where commercial deployment requires stable procurement frameworks, long-term financing structures, and coordinated industrial planning.

The next phase of the SMR market will not be defined solely by reactor performance.
It will be defined by whether the industry can build commercial structures capable of supporting serial deployment at scale.

Because the central challenge facing SMRs is no longer purely an engineering challenge.

It is increasingly a market design challenge.

The post The SMR commercial model problem appeared first on Damona | Strategy consulting | Nuclear industry.

Wind, solar, and storage dominate the public conversation around the energy transition. They attract the majority of political attention, investment flows, and infrastructure planning.

They are necessary. They are not sufficient. Because electricity is only part of the challenge.

Heat, the energy used to forge steel, fire cement kilns, refine chemicals, and process industrial feedstocks, accounts for nearly half of global final energy consumption, according to the International Energy Agency. In industry specifically, heat remains the dominant energy input, and the vast majority of it is still generated by burning fossil fuels directly.

This is one of the most structurally difficult problems in the energy transition. And it is one that nuclear may be uniquely positioned to help solve.

Industrial decarbonization has a heat problem

Industry remains the largest source of direct carbon emissions globally, accounting for approximately 37% of total CO₂ emissions when direct combustion and indirect electricity-related emissions are combined.

Within that total, a small number of sectors drive a disproportionate share of the challenge.

Steel production alone contributes roughly 7% of global CO₂ emissions, with blast furnace processes requiring temperatures above 1,000°C. Cement production typically requires kiln temperatures of 1,400–1,500°C and generates unavoidable process emissions from limestone calcination. Chemical manufacturing spans a wide range of heat-intensive applications, many of which require continuous, high-temperature energy across highly integrated process chains.

These are not peripheral sectors. They are foundational to the global economy — and among the hardest to decarbonize.

Why existing pathways leave a gap

Most industrial decarbonization strategies currently rely on three pathways: electrification, hydrogen, and carbon capture.

Each has a role to play. None fully solve the heat challenge on their own.

Direct electrification is effective for lower-temperature industrial applications and will remain an important part of the transition. But for many continuous, high-temperature processes, scaling electric heat economically remains challenging.

Green hydrogen holds significant long-term promise, particularly in steelmaking and chemicals. Yet cost, infrastructure requirements, electrolyser deployment, and renewable power availability continue to constrain large-scale deployment. For many industrial operators, hydrogen remains a medium- to long-term pathway rather than an immediate solution.

Carbon capture can reduce emissions from existing fossil-fired processes, but it does not eliminate dependence on combustible fuels. It reduces the carbon intensity of the system without fundamentally changing its underlying energy architecture.

The result is a persistent gap in the industrial decarbonization toolkit:
a shortage of scalable, clean, continuous high-temperature heat solutions.

Why nuclear deserves greater attention

Nuclear reactors produce heat first and electricity second. That matters.

Conventional light water reactors already generate steam at approximately 300°C, suitable for district heating and a range of lower-temperature industrial applications. But the more significant strategic opportunity lies in advanced reactor technologies designed specifically for higher-temperature output.

High-Temperature Gas-cooled Reactors and Very High Temperature Reactors are designed to deliver outlet temperatures in the 700–950°C range, making them relevant for a far broader range of industrial applications. At the upper end of that spectrum, they also enable more efficient hydrogen production pathways than conventional electrolysis.

This is not theoretical physics but an engineering and deployment challenge.

Nuclear process heat has already been demonstrated across multiple non-electric applications, and high-temperature industrial integration is increasingly moving from conceptual design toward commercial demonstration.

The market is beginning to move

Momentum is building.

China’s HTR-PM at Shidaowan became the world’s first commercial high-temperature gas-cooled reactor in 2023, establishing a critical proof point for advanced nuclear heat technologies. In the United States, the Department of Energy’s Industrial Decarbonization Roadmap identifies advanced nuclear as a strategic option for industrial heat supply, while national laboratories continue developing integration models for nuclear-industrial thermal systems.

At the same time, several advanced reactor developers such as Jimmy are explicitly designing their commercial offerings around industrial heat applications rather than grid-only electricity supply.

The emerging model is clear:
co-located nuclear and industrial assets, linked through long-term thermal offtake arrangements.

For industrial operators, this creates the possibility of securing stable, low-carbon heat directly at source while reducing exposure to grid congestion, transmission losses, and power market volatility.

Why this matters strategically

For many industrial operators, energy is not just an emissions issue. It is a competitiveness issue.

Steel, cement, and chemicals are globally traded commodities produced in margin-sensitive environments. Energy price volatility directly impacts operating margins and long-term investment decisions.

The European energy crisis of 2022–2023 exposed the vulnerability of industrial sectors reliant on gas-fired heat. Meanwhile, mechanisms such as the EU’s Carbon Border Adjustment Mechanism are turning carbon intensity into an increasingly explicit financial variable for exporters into European markets.

In this context, decarbonized industrial heat is no longer simply an ESG consideration.
It is becoming a strategic determinant of industrial competitiveness.

Nuclear process heat offers a pathway to address that challenge structurally: delivering continuous, carbon-free thermal energy with long-term pricing stability and limited fuel cost exposure.

The window for strategic positioning is open now

High-temperature nuclear heat is not yet available at broad commercial scale.

But industrial decarbonization decisions are not made on deployment timelines alone. They are shaped by long asset cycles, infrastructure planning horizons, and regulatory lead times.

Industrial assets commissioned today may operate for 30 to 50 years. Energy infrastructure decisions made in this decade will shape competitiveness and emissions trajectories well beyond 2050.

The companies that begin assessing nuclear heat pathways now, evaluating site compatibility, technology readiness, regulatory implications, and commercial structures, will be better positioned when deployment reaches maturity.

Those that wait for the technology to become fully commoditized may find that the strategic window has already narrowed.

A strategic reframing

The industrial heat challenge remains one of the least discussed, and most consequential, bottlenecks in the energy transition.

Nuclear may not be the answer for every industrial application.
But for many hard-to-abate sectors, it is one of the few scalable pathways to address the problem at its source.

The question is no longer whether industrial heat must decarbonize.

It is which technologies, and which operators, will move early enough to shape that transition rather than react to it.

The post Nuclear energy and the industrial decarbonization imperative appeared first on Damona | Strategy consulting | Nuclear industry.

What is emerging is not simply a question of “how to power AI”, but a broader challenge: how to align long-term, capital-intensive nuclear assets with a form of electricity demand that is growing fast, operating continuously, and increasingly strategic for national economies.

For nuclear stakeholders, this moment calls for strategic clarity rather than technological debate.

When digital growth becomes baseload demand

AI is often framed as a software revolution. In reality, it is a physical one. Large-scale model training and inference rely on vast data-centre infrastructures that operate around the clock. These facilities are not flexible loads. They require continuous power, extremely high reliability, and predictable long-term supply.

Energy system planners are now confronting projections that show global data-centre electricity consumption approaching twice today’s levels by the end of the decade, driven by AI. In several advanced economies, expected growth in data centre demand alone rivals or exceeds historical annual increases in total electricity consumption.

This matters because it changes the nature of demand. Unlike electrification of transport or heating, which introduces variability and behavioural elasticity, AI-driven data centres behave much more like industrial baseload. They do not follow daily or seasonal cycles. They do not tolerate curtailment. And they increasingly influence where generation assets are built.

For the nuclear industry, this represents a rare alignment between demand characteristics and nuclear power’s core strengths.

Why energy systems are struggling to absorb this shift

Today’s energy systems were not designed for this growth profile. Variable renewables continue to scale rapidly, but their intermittency creates challenges when matched with 24/7, non-interruptible demand. Natural gas offers dispatchability, yet raises long-term questions around emissions exposure, fuel price volatility and geopolitical dependence. Grid reinforcement alone is proving slower and more capital-intensive than many governments and utilities anticipated.

As a result, data centre operators, utilities and policymakers are moving beyond short-term power procurement and into infrastructure strategy. Power supply is no longer treated as a marginal cost of digital expansion, but as a determinant of competitiveness, resilience and sovereignty.

It is in this context that nuclear power is returning to strategic discussions, not as an ideological choice, but as an infrastructure option whose attributes match emerging system needs.

Nuclear power as a strategic infrastructure asset

Nuclear energy’s relevance to data centre growth lies less in innovation narratives than in fundamentals. High capacity factors, long asset lifetimes, low operational emissions and predictable output make nuclear uniquely suited to serve continuous, large-scale demand.

This logic is increasingly reflected in market signals. Nuclear assets are being re-evaluated not only as electricity generators but also as anchors of regional energy systems. Interest from technology companies in long-term nuclear offtake, including through existing plants, life-extension projects, and, prospectively, new builds, reflects a broader recognition: stable power is becoming a strategic input to digital economies.

At the same time, expectations remain realistic. Nuclear alone cannot meet the entire growth in data centre demand, nor can capacity be deployed overnight. Large reactors, small modular reactors and life-extension programmes all come with distinct timelines, regulatory pathways and risk profiles. The strategic question is therefore not whether nuclear “wins”, but how nuclear fits into a diversified, resilient energy system designed for the next thirty to fifty years.

The core issue is not technology but decision architecture

For nuclear stakeholders, the most difficult challenges raised by AI-driven demand are not technical. They are structural.

How should new nuclear capacity be sited when demand is geographically concentrated but grids are constrained? How should ownership and offtake models evolve when customers seek long-term certainty but assets operate over several decades? How do regulators adapt frameworks designed for centralised generation to new configurations such as co-location, dedicated supply or hybrid public-private models?

These questions cut across energy policy, industrial strategy, finance and governance. They require coordination between actors with different incentives, time horizons and risk tolerances. They also demand a level of strategic integration that the nuclear sector, historically segmented between policy, engineering, operations and finance, is still adapting to.

This is where the role of strategic nuclear advisory becomes critical.

What this means for nuclear leaders

For utilities, the rise of AI-driven demand introduces new customer archetypes: fewer in number, larger in scale, and far more strategic than traditional industrial loads. For governments, it reinforces the link between nuclear policy and economic competitiveness. For investors and developers, it reshapes the risk-return profile of long-term nuclear assets.

Responding effectively requires more than incremental optimisation. It requires clear strategic choices, robust operating models, and delivery frameworks capable of performing over long lifecycles in evolving contexts.

At Damona, we work with nuclear stakeholders precisely on these challenges. Our focus is not on promoting technology, but on supporting clarity in complex decisions: aligning strategy with regulatory reality, structuring operating models for long-term performance, shaping industrial and supply-chain strategies, and supporting disciplined capital project delivery.

AI is accelerating change in electricity demand. Nuclear power is increasingly part of the strategic response. The decisive factor, however, will be how well organisations connect ambition to execution.

For the nuclear industry, this is not a disruption to fear. It is a strategic moment to shape the next phase of its role in the global energy system.

The post Why the next wave of electricity demand is a strategic issue for the nuclear industry appeared first on Damona | Strategy consulting | Nuclear industry.

As an example of commitment, the US Government and Westinghouse have committed to build AP1000 and AP300 reactors for at least $80 billion. This one-in-a-lifetime partnership will allow the US Government to receive 20% of any cash distributions to the portion above $17.5 billion. But more interestingly, when looking at the details of this agreement, if before 2029, the valuation of Westinghouse is above $30 billion, the US Government can force an IPO and has 5 years to buy up to 20% of the shares at a discounted price. This shows confirmation of a strong renaissance for nuclear, with governments such as in the US particularly bullish.

This surge of demand, however, exposes a growing vulnerability. Nuclear energy depends on complex, highly specialized, and globally interdependent supply chains. In an era defined by geopolitical fragmentation, resource nationalism, and industrial bottlenecks, these supply chains are increasingly under strain. For executives, policymakers, and investors, resilience is no longer a secondary consideration: it is a strategic determinant of whether nuclear’s renaissance can be delivered on time and at scale.

The strategic bottlenecks

Unlike other energy technologies, nuclear relies on a small number of qualified suppliers, with strict standards and long lead times. The most critical bottlenecks include:

• Heavy manufacturing capacity: Large forgings for reactor pressure vessels, steam generators, and pressurizers are manufactured by only a handful of facilities worldwide, many concentrated in East Asia. Lead times can stretch years, and disruptions can cascade across multiple projects. Those equipment are known as long-lead items.
  
• Nuclear-grade materials and components: Pumps, valves, instrumentation, and control systems must meet stringent nuclear qualification standards. Supplier pools are narrow, and substituting components is often impossible without redesign and relicensing.
  
• Fuel cycle dependencies: Europe has long depended on imported uranium and enrichment, with Russia historically supplying about 20% of global enrichment capacity. Alternatives exist in the UK, in the Netherlands, Germany, France, China, and the U.S., but diversifying requires years of investment and coordination.
  
• Workforce and specialist services: Nuclear construction depends on highly skilled welders, inspectors, and project managers, many of whom are approaching retirement. Shortages of qualified personnel are emerging as a bottleneck as critical as physical components.

Geopolitics and fragmentation

Geopolitical dynamics are intensifying supply chain risks. The conflict in Ukraine has triggered an urgent reassessment of fuel dependencies, particularly in Europe. The EU is now moving to phase out reliance on Russian enrichment and conversion services, but building alternative capacity will take years and billions in investment. Alternatives to ROSATOM such as Westinghouse and FRAMATOME are also now offering VVER-compatible fuel to diversify fuel manufacturing options.

Elsewhere, resource nationalism is reshaping uranium markets. Kazakhstan, the world’s largest uranium producer, has signaled its intention to prioritize domestic processing and partnerships with aligned states. The U.S. has introduced incentives to rebuild domestic enrichment capacity and recently awarded six companies with energy contracts, while China is securing long-term supply contracts across Africa and Central Asia. In this fragmented context, uranium and enrichment are no longer commodities traded over the counter but strategic assets embedded in geopolitical competition.

Fragmentation also undermines international collaboration. While organizations such as the IAEA and OECD-NEA promote cooperative approaches, national industrial strategies increasingly emphasize domestic capacity and “friend-shoring.” This reduces economies of scale and creates duplication of effort, raising costs for all players.

The economic consequences of weak supply chains

The economic impact of supply chain weakness is profound. Delays in component delivery or shortages of qualified vendors are among the most common causes of cost overruns in nuclear projects. A single missed delivery of a reactor pressure vessel can delay an entire project by years. For large-scale reactors, such setbacks translate into billions in additional costs. Let alone quality risks such as seen with the vessel of the EPR Flamanville.

For SMRs, which promise faster deployment through modularity, the supply chain is even more critical. Their business model depends on repeatability and standardization, akin to shipbuilding or aerospace. Without industrial capacity to mass-produce modules at scale, SMRs risk becoming boutique projects, losing the very economic advantage that makes them attractive. As the OECD-NEA has highlighted, the path from FOAK to NOAK depends entirely on robust supply chains able to deliver at scale and cost.

The financial sector is increasingly aware of these risks. Investors demand evidence of credible supply chain strategies before committing to multi-billion-dollar projects. For utilities and developers, this means that supply chain resilience is no longer just an operational issue—it is central to financial bankability.

Central and Eastern Europe: a strategic opportunity

While supply chain vulnerability is a challenge, it also creates opportunities for new players. Central and Eastern Europe, where many new nuclear projects are planned, is well-positioned to capture industrial value. The region has a strong base in heavy industry, engineering, and skilled labor, making it a natural candidate to host parts of the nuclear supply chain.

Poland has launched initiatives to attract large scale and SMR developers and is exploring partnerships with Western vendors. The Czech Republic is leveraging its historical expertise in reactor design and manufacturing to secure a role in both large reactor and SMR supply chains. Romania, with its plans for CANDU refurbishment and SMR deployment, is positioning itself as a hub for both construction services and long-term fuel cycle activities.

By integrating nuclear into broader industrial policy, CEE countries could transform nuclear projects from technology imports into engines of domestic industrial renewal. The choice is not only about energy, it is about whether nuclear becomes a strategic lever for reindustrialization, exports, and long-term competitiveness.

Building resilience through strategy

Strengthening nuclear supply chains requires coordinated action at multiple levels. Diversification of suppliers is essential, reducing dependence on single points of failure. Workforce strategies must address demographic challenges, with new pipelines of engineers, welders, and project managers built through apprenticeships and university partnerships.

Standardization of designs is another key factor. The proliferation of bespoke reactor designs fragments demand and weakens supply chains. Consolidating around standardized models enables economies of scale, reduces qualification costs, and creates predictable demand for suppliers. This is particularly important for SMRs, where standardization is central to their economic rationale.

Finally, governments and private firms must collaborate to build industrial resilience. Public funding can support new manufacturing capacity, while export credit agencies and international financing institutions can de-risk investment in supply chains. For private developers, embedding supply chain strategy into project planning is no longer optional—it is a prerequisite for success. Lessons from aerospace and semiconductors are clear: industrial ecosystems do not emerge spontaneously; they are cultivated through sustained investment, policy alignment, and long-term partnerships.

The nuclear renaissance will be defined not only by technological breakthroughs or political commitments but by the resilience of the supply chains that make them possible. In a fragmented world, nuclear components, fuel cycles, and skilled labor are not just industrial inputs—they are strategic assets.

The companies and countries that recognize this early, investing in diversification, industrial capacity, and workforce renewal, will secure a competitive advantage. They will deliver projects on time, attract investor confidence, and position themselves as leaders in a sector central to energy security and decarbonization. Those who ignore the supply chain challenge may find that their nuclear ambitions are constrained not by technology, but by the weakest link in a fragile global system.

Next-generation nuclear technologies, including small modular reactors SMRs -, advanced fission concepts, and emerging fusion designs, offer flexible, low-carbon, and resilient solutions that meet the dual needs of decarbonization and energy security. With global electricity demand expected to double by 2050, scaling nuclear innovation is not a matter of technological feasibility—but one of strategic execution.

Unlocking climate gains through advanced nuclear technologies

Nuclear energy already provides one-quarter of global low-carbon electricity, and it is expected to double its contribution by mid-century. That growth will be driven not only by conventional large-scale plants, but by modular and advanced systems that can decarbonize hard-to-abate sectors, support hydrogen production, complement intermittent renewables, and be closer to the CO2 emission sources.

SMRs, for instance, offer reduced capital risk, factory-built modules, and the ability to serve remote or industrial regions that lack grid-scale infrastructure. Fusion power—though still at a lower TRL than some fission technologies—has made significant strides, with both public and private initiatives breaking new ground in energy yield and magnetic confinement.

Countries with ambitious climate targets are moving fast. The global pledge launched at COP28 to triple nuclear capacity by 2050 reflects a broad recognition that net-zero cannot be achieved without nuclear. Excluding nuclear energy from the clean energy mix would make international climate objectives unreachable.

Modernizing regulation for a modular, fast-moving Industry

One of the primary constraints to nuclear innovation is not engineering—it’s regulation. Most existing frameworks were designed for gigawatt-scale plants, not for modular or non-light-water reactors.

In response, agencies across North America and Europe are evolving their processes. The U.S. NRC has adopted new licensing rules tailored explicitly to advanced reactor developers. Canada and the UK are working toward cross-border alignment on SMR licensing. Still, the pace remains uneven. A patchwork of standards across jurisdictions complicates export strategies and raises project risk.

There is growing momentum behind innovation zones and regulatory sandboxes—controlled spaces where developers can pilot technologies under adaptive regulatory conditions. These offer governments a chance to de-risk innovation without compromising safety.

A clear example of this regulatory simplification is President Trump’s Nuclear Reactor Pilot Program, supported by the U.S. DOE. DOE is going to work with 11 advanced reactor startups to reach first criticity on July, 4th 2025. The selected companies are: Aalo, Antares Nuclear, Atomic Alchemy, Deep Fission, Last Energy, Oklo, Natura Resources, Radiant, Terrestrial and Valar Atomics.

Building the ecosystem: supply chains, skills, and investment

To scale nuclear innovation beyond a few pilot sites, supply chains must be reconfigured for speed, volume, and interoperability. The global nuclear sector currently lacks sufficient component manufacturing capacity and skilled personnel to meet the projected surge in demand.

The World Nuclear Association has emphasized the urgent need to boost supply chain capability and talent development, especially for pressure components, instrumentation, and high-specification welding. This aligns with recent calls at the NuclearEurope 2025 Conference, attended by Damona, where policymakers and industrial leaders warned that the EU must strengthen its competitiveness in nuclear manufacturing or risk dependence on foreign suppliers.

Some countries are responding with bold industrial strategies. Romania’s investment in SMRs positions it as a regional hub, while France is reshoring reactor component production to support its new nuclear roadmap. This can be seen with the extension of FRAMATOME Le Creusot, a key site in France able to manufacture Steam Generators and Pressure Vessels. Cross-border partnerships—such as the £2.5 billion collaboration between the UK and the Czech Republic—are also enabling shared risk and knowledge transfer.

Rethinking finance and risk

Advanced nuclear projects require significant upfront capital, but the long-term returns are stable and attractive. The challenge is that most financial frameworks are geared toward shorter-term renewable projects, not multi-decade nuclear investments.

A step change in financing models is now underway. Sovereign guarantees, blended finance structures, and public-private partnerships are being used to accelerate deployment while managing risk. Some countries are even setting up in place their own development structure such as the UK with Great British Nuclear.

There is also a broader shift toward viewing nuclear not just as infrastructure, but as a strategic asset—one that can reduce dependency on fossil fuels, increase energy security, and create high-value industrial jobs.

Public trust and global coordination

Scaling nuclear technologies also depends on public perception. Despite decades of safe operation, concerns around waste, safety, and cost continue to shape public discourse. Yet newer designs embed passive safety features, reduce waste volumes, and offer dramatically shorter construction timelines.

Public engagement must evolve—moving from top-down messaging to participatory decision-making.  

Finland’s successful repository development process, built on community inclusion, demonstrates how trust can be earned over time. In developing nations, this approach is even more critical. From Damona’s work in Southeast Asia, we see that engaging with tribal and village chiefs, local community leaders, and traditional authorities is not only respectful but strategic: it anchors projects in cultural legitimacy and mitigates the risk of costly setbacks. The experience of the Khilifi nuclear project in Kenya, where weak local support forced relocation, highlights how overlooking social dynamics can derail entire programs.

At the international level, knowledge sharing and coordination remain essential. Platforms like the IAEA and UNECE facilitate cooperation across borders, while industry-led forums enable the faster dissemination of best practices.

A strategic playbook for the decade ahead

To ensure the success of nuclear innovation over the next decade, stakeholders must align on five imperatives:

• Policy coherence: embed nuclear into national climate and energy strategies, with clear regulatory timelines.
• Workforce readiness: scale training programs to meet rising demand in construction, operations, and regulation.
• Global standardization: advance mutual recognition of reactor designs and safety protocols across key markets.
• Investment innovation: develop financial products that reflect the risk-return profile of advanced nuclear energy.
• Public partnership: engage communities early and often, building trust through transparency and inclusion.
  

Nuclear innovation is a strategic advantage

Next-generation nuclear is no longer just a technical frontier—it is a strategic advantage for countries that seek to lead the energy transition. It can stabilize grids, decarbonize industries, and secure long-term economic resilience.

However, to unlock that potential, governments, companies, and institutions must act in concert—with urgency, coordination, and a clear vision.

The post How strategic innovation in nuclear can deliver climate and energy resilience appeared first on Damona | Strategy consulting | Nuclear industry.

Despite increasing political will — from the COP28 pledge to triple capacity to the Net Zero Nuclear initiative — the European nuclear sector still faces systemic constraints that pilot projects and policy slogans alone can’t solve.

This isn’t just a matter of building more plants. It’s about scaling the entire ecosystem — from financing frameworks to grid architecture, permitting reform to skilled workforce availability — to deliver nuclear power as a foundational pillar of European industrial strategy.

Grid-scale planning, not one-off announcements

Nuclear’s role in the energy mix is often reduced to political binaries — yes or no, build or phase out. This misses the structural truth: nuclear is not just a power source, it’s a stabilizer. It anchors baseload generation, enables deep electrification of industry, and offers long-term energy sovereignty.

But ambition without system-level coordination is not enough. Projections indicate that nuclear capacity must more than double by 2050 to meet global climate goals; however, Europe’s current energy infrastructure and fragmented planning threaten to bottleneck progress. Grid expansion, market reform, and interconnection investments are still lagging. And without grid-level planning that integrates nuclear alongside renewables, energy security will remain fragile.

At the recent NuclearEurope 2025 annual conference, stakeholders made it clear: Europe must shift from politically driven energy transitions to fact-based, system-integrated strategies. The inclusion of nuclear in EU energy policy must go beyond targets — it must shape regulation, investment rules, and grid architecture.

A supply chain built for delivery, not demonstration

The nuclear supply chain in Europe has not kept pace with political ambition. Project timelines, material cost fluctuations, and skills shortages expose structural weaknesses in both capacity and resilience. Many suppliers operate with thin margins, constrained pipelines, and limited scalability. Yet the demand is real — and growing.

With SMR deployments accelerating, decommissioning projects expanding, and new builds on the horizon, Europe must move from reactive procurement to proactive industrial strategy. This means long-term orders, strategic localisations, and digitised oversight across the vendor ecosystem.

It also requires a mindset shift: nuclear is not a boutique industry. It’s critical infrastructure. Without policy and financial instruments that match that reality — such as robust Contracts for Difference, blended financing mechanisms, and cross-border R&D funding — the gap between ambition and delivery will widen.

From fragmentation to execution

Europe’s challenge isn’t a lack of technological capability — it’s fragmented governance. Nuclear policies remain national, while supply chains, talent pools, and financing are increasingly global. The absence of coordinated execution frameworks undermines even the most promising initiatives.

Across the board, players are calling for alignment between permitting agencies, market operators, regulators, and industrial consortia. A new European nuclear strategy must embrace interoperability, from licensing timelines to transmission upgrades and cross-border labor recognition.

The case for change is mounting. Recent leadership shifts in Germany may soften historic opposition to nuclear power within key EU forums. And countries like Romania, Poland, and the Czech Republic are already spearheading advanced reactor collaborations, including SMRs and public-private alliances, demonstrating that a more agile, scalable model is possible.

Building the new nuclear system

Standalone projects or slogans will not secure nuclear energy’s future in Europe. It will be secured through deep, systemic transformation — integrating nuclear into every level of energy and industrial policy.

This means:

• Rebuilding supply chains for volume, resilience, and innovation
• Embedding nuclear in grid and infrastructure planning
• Modernising permitting and standardising safety frameworks
• Strengthening cross-border collaboration on talent, R&D, and financing
• Incentivising long-term investment over political cycles

Nuclear is no longer just a climate solution. It’s a sovereignty solution, a competitiveness solution, and a long-term societal investment. Those who build the system around it — with strategic clarity, industrial pragmatism, and policy consistency — will shape not only Europe’s energy transition but also its global relevance in the decades to come.

The post Why Europe must rethink nuclear deployment at scale appeared first on Damona | Strategy consulting | Nuclear industry.

This shift is not merely rhetorical. Legislative frameworks, cross-border agreements, and investment priorities are aligning in support of a revitalized nuclear agenda.

Energy security in a volatile geopolitical landscape

Russia’s invasion of Ukraine in 2022 acted as a seismic shock to Europe’s energy system, exposing the continent’s reliance on imported fossil fuels and highlighting the fragility of energy security in times of geopolitical unrest. The crisis prompted a comprehensive re-evaluation of energy strategies across EU member states, with a renewed emphasis on reducing external dependencies. As natural gas flows were disrupted and electricity prices surged, policymakers and energy experts began reassessing the role of nuclear power, not just as a decarbonization tool, but as a lever of sovereignty and resilience.

In this context, nuclear energy has moved from the periphery to the center of strategic discussions. The European Commission now formally recognizes nuclear power as essential to achieving both climate targets and energy independence. This shift is enshrined in the EU Taxonomy for Sustainable Activities, which classifies nuclear as a sustainable investment, paving the way for public and private funding in new and existing infrastructure. Notably, the longstanding policy divide between France and Germany has begun to narrow. France has long advocated for nuclear power as a clean, reliable, and strategic energy source, while Germany, after completing its nuclear phase-out in 2023, is now signalling a more pragmatic stance. The two countries have reached a diplomatic understanding, allowing for greater flexibility in national energy choices and setting the stage for collaborative investment and innovation across the EU.

A diverse and evolving nuclear landscape

The European Union today presents a highly diversified nuclear profile, with 12 out of 27 member states operating nuclear reactors that collectively account for around 25% of the bloc’s total electricity generation. These reactors range from traditional large-scale pressurised water reactors to cutting-edge designs. France remains the largest nuclear power producer in the EU, with over 50 reactors supplying more than 70% of its electricity. Other countries such as Finland, Slovakia, and Hungary are actively investing in reactor life extensions, capacity upgrades, and new builds, often with support from European or international financing mechanisms.

Emerging players are also beginning to reshape the landscape. Denmark, which banned nuclear power in 1985, is conducting feasibility studies on advanced reactor technologies, including SMRs, to supplement its wind-heavy grid and ensure year-round stability. In Eastern Europe, Poland is preparing to build its first nuclear plant, backed by U.S. and South Korean technology partners, as part of its strategy to transition away from coal. Spain, while officially maintaining its nuclear phase-out trajectory, has shown signs of reconsideration. Recent statements from government officials suggest that grid stability and decarbonization targets may warrant a reassessment of current timelines, especially in the wake of regional blackouts and the growing complexity of managing renewable-heavy systems.

As energy systems across Europe become more interconnected and electrified, nuclear power is being re-evaluated not just on technical merits, but as a cornerstone of long-term energy system resilience. The current momentum reflects both urgency and opportunity: a chance to modernize Europe’s nuclear fleet, diversify energy supply chains, and reinforce the continent’s commitment to net-zero targets while maintaining system stability.

Policy acceleration and cross-border cooperation

Legislative momentum is also increasing. The EU’s updated energy strategy includes streamlined permitting processes for new nuclear projects and encourages cross-border cooperation to strengthen supply chains and regulatory oversight. The European Nuclear Safety Regulators Group is actively harmonizing safety standards across member states, enabling faster deployment and greater public trust.

At the same time, platforms like Nucleareurope are fostering collaboration between governments, vendors, and utilities to share best practices and accelerate delivery. Pan-European R&D efforts are being supported through Horizon Europe, which funds research into advanced reactor design, waste reduction, and digital integration.

A complementary role to renewables

Nuclear is not positioned as a competitor to renewables but as a complement. The intermittency of solar and wind energy requires a stable, dispatchable base load—one that nuclear can uniquely provide without increasing emissions. As the share of renewables grows, the ability of nuclear to stabilize grids and provide inertia becomes more strategically important.

Moreover, advanced reactors offer the potential to decarbonize hard-to-electrify sectors. High-temperature reactors could supply clean process heat to industrial clusters, while SMRs could be co-located with data centers or hydrogen hubs.

Investment climate and market signals

The investment landscape for nuclear energy in Europe is undergoing a notable transformation. After a prolonged period of uncertainty and underinvestment, market signals are pointing to renewed interest from both institutional investors and energy companies. Several major utilities—particularly in France, Finland, and Central Europe—have unveiled plans for new builds, life extensions, and partnerships with international vendors to deploy advanced reactor technologies. Private capital, once hesitant due to regulatory complexity and reputational risk, is increasingly entering the market, particularly in the form of venture and growth equity investments into SMR developers and nuclear innovation startups focused on next-generation fuels, digital reactor management systems, and advanced manufacturing.

This resurgence is underpinned by EU-wide policy alignment that recognizes nuclear energy’s role in meeting net-zero goals. The inclusion of nuclear within the EU Taxonomy for Sustainable Activities has been a critical step, providing much-needed clarity for investors and unlocking access to green finance instruments. As a result, financial institutions and pension funds are beginning to reconsider nuclear as part of their ESG-compliant portfolios, especially for projects that meet stringent safety, environmental, and governance criteria. Additionally, the European Investment Bank and national promotional banks are showing greater flexibility in supporting nuclear-related infrastructure, particularly where alignment with energy transition goals is precise.

Despite this progress, financing nuclear power remains a structurally complex endeavour. The sector’s high capital intensity, long lead times, and significant regulatory overhead make it a challenging fit for liberalized electricity markets that prioritize short-term returns. In response, policymakers and developers are exploring innovative financial structures to close the viability gap. Regulated Asset Base models, already tested in the UK, are being examined by other member states to reduce risk premiums by providing predictable revenue streams during the construction phase. Contracts for Difference are also gaining momentum as a tool to provide long-term price certainty for low-carbon electricity. In parallel, government-backed loan guarantees and public-private co-investment vehicles are being introduced to ease access to debt and improve bankability.

These evolving financial mechanisms represent more than just risk mitigation—they are a recognition that meeting Europe’s decarbonisation and energy security targets will require long-term, patient capital. As confidence builds and frameworks mature, nuclear energy is steadily regaining its position as a viable, investable asset class in the European energy mix.

Europe’s nuclear revival is more than a temporary response to energy shocks—it is a structural recalibration of the continent’s long-term energy strategy. The path forward is not without obstacles: legacy perceptions, public opposition, and regulatory complexity persist. But the direction is clear. Nuclear energy is once again a strategic asset—essential to decarbonization, energy sovereignty, and industrial competitiveness in the 21st century.

Why nuclear needs global thinking

Nuclear energy is not merely a domestic concern. It is shaped by international fuel markets, global safety standards, and collective efforts to meet climate targets. The IAEA estimates that nuclear capacity must more than double by 2050 to support global decarbonization goals. Achieving that will require more than individual effort—it will demand global thinking.

Collaborative frameworks enable countries to mitigate financial and technical risks by forming joint ventures and participating in multilateral funding models. This enables ambitious projects to get off the ground more quickly and efficiently. International cooperation also promotes the standardization of licensing and safety protocols, which improves project timelines and enhances public trust. Additionally, pooling expertise and research efforts across borders fuels innovation, thereby accelerating the deployment of advanced technologies, such as small modular reactors (SMRs) and next-generation systems.

Programs like the NICE Future initiative, European collaborative fusion research (where the Fusion For Energy, the EU fusion agency is involved in ITER), and bilateral agreements between nuclear leaders such as France, Canada, and Japan demonstrate that international cooperation is no longer optional—it’s foundational.

Challenges of global nuclear work

Despite the benefits, international nuclear collaboration comes with a unique set of challenges. The most immediate is regulatory fragmentation. Every country has its own nuclear regulatory body, which sets differing criteria for safety, environmental assessment, and project approval. This patchwork creates complexity for companies attempting to deploy standardized technologies across multiple markets.

Local alignment is another significant hurdle. Projects may span countries, but they land in communities. That means international partners must take the time to understand local socio-political dynamics, public sentiment, and regional development needs. Without this local buy-in, even the best-laid technical plans can stall.

Cultural and institutional differences can also strain multinational partnerships. Different working languages, management styles, and operational expectations can slow progress or lead to misunderstandings if not proactively managed. Trust and clarity must be built through consistent engagement, shared goals, and transparent communication.

To work across borders effectively, nuclear players must be both globally minded and locally anchored—a combination that demands strategic foresight and cultural fluency.

International partnerships in action

Several international partnerships and agreements illustrate the growing importance of global collaboration. The UAE’s Barakah nuclear power plant was built through a collaboration between the Emirates Nuclear Energy Corporation and Korea Electric Power Corporation. This cross-border partnership enabled technology transfer, local workforce development, and knowledge exchange.

Similarly, France and India have engaged in long-term cooperation around nuclear technology, with plans for six EPR reactors at the Jaitapur site. South Korea has developed strong nuclear export partnerships with countries like Egypt, Poland, and Saudi Arabia, while China is extending its nuclear technology to Pakistan and make a dent a trying to enter the European market with Bradwell B in the UK.

The United States has made global cooperation a central pillar of its advanced reactor strategy, working closely with Canada and the UK to harmonize regulatory frameworks and support the deployment of small modular reactors. Additionally, the Partnership for Transatlantic Energy and Climate Cooperation (P-TECC) and the Clean Energy Ministerial’s NICE Future initiative exemplify multilateral efforts to align international development.

Global forums and summits are essential. Platforms like the IAEA General Conference, the World Nuclear Exhibition, and the Nuclear Energy Summit provide critical spaces for governments, regulators, and industry leaders to align on shared goals, showcase innovations, and address collective challenges. The 2023 pledge by more than 30 countries to triple nuclear capacity by 2050—signed at COP28—highlights the scale and urgency of global alignment.

These examples reinforce that no country can afford to act in isolation. A connected, cooperative global approach is not just an advantage—it’s a necessity.

The path forward

The global nuclear revival is underway. But to avoid duplication, inefficiency, and public resistance, we must act in concert. Collaboration is the foundation for a resilient, responsive, and forward-looking nuclear sector.

The coming decades will see nuclear energy deployed in new ways, from powering green hydrogen production to supplying clean heat for industry. These advances will only scale if a cohesive global effort supports them. Regulatory convergence, shared innovation, and multilateral financing are not distant ideals—they are immediate requirements.

In this new landscape, success will belong to those who can bridge divides and align diverse actors around a common purpose. The next chapter of nuclear energy won’t be written country by country. It will be written together.

Introduction to blockchain technology

Blockchain technology is a digital platform known for its key characteristics of decentralization, immutability, and transparency. It operates as a distributed ledger that records all transactions across a network of computers. Each transaction is recorded in a “block” and linked to previous and subsequent blocks, forming a chronological “chain.” This structure ensures that information cannot be altered once it is entered, thereby providing a secure and tamper-proof system. This technology is widely recognized for its potential to enhance security and efficiency in various sectors, including finance, supply chain management, and now, nuclear security.

Blockchain’s impact on nuclear material tracking

Blockchain technology represents a transformative shift in how nuclear materials are tracked, managed, and audited. It introduces a paradigm where each phase of a nuclear material’s lifecycle—from production to disposal—is documented in an immutable and transparent ledger. This digital innovation ensures that all records are tamper-proof and readily available, which is essential for a material that poses significant security risks.

The process begins at the very inception of nuclear materials. As soon as nuclear material is produced, its details are recorded on a blockchain. This initial record includes the material’s type, quantity, form, activity and any other relevant data defining its characteristics. Each subsequent step—whether the material is moved, utilized in energy production, or transferred between facilities—is logged as a separate transaction on the blockchain. This creates a chronological chain of custody that is both verifiable and irreversible.

The advantage of using blockchain in this context is manifold. For one, it enhances the security of nuclear materials. By creating a permanent record of every transaction that cannot be altered retroactively without detection, blockchain technology significantly lowers the risk of illegal or unauthorized activities. Each entry requires validation by multiple parties before it is added to the ledger, which also disperses the control of the information, reducing the potential for fraud or data manipulation.

Moreover, blockchain’s transparency and real-time data access are invaluable for regulatory bodies and international watchdogs like the International Atomic Energy Agency. These entities require consistent and accurate information to ensure that nuclear materials are not diverted to illicit uses or fall into the wrong hands. Blockchain enables real-time auditing and monitoring, facilitating swift responses to any discrepancies or anomalies in the supply chain. It effectively supports nuclear non-proliferation treaties and domestic regulations by providing a reliable tool for enforcing compliance.

In addition to security and compliance, blockchain technology simplifies the logistical aspects of nuclear material management. The immutable record of transactions allows for more straightforward and quicker verification processes, reducing administrative burdens and enhancing operational efficiencies. This can be particularly beneficial for nuclear waste management, where accurate historical data are crucial for tracking the decay and transformation of materials over time.

Blockchain also introduces the possibility of integrating smart contracts—self-executing contracts with the terms of the agreement directly written into code—into the nuclear material supply chain. These contracts could automate many aspects of nuclear material management, such as triggering alerts if materials are not processed according to schedule or if unauthorized access is detected. This not only enhances operational efficiency but also significantly increases the level of security by reducing human error and the potential for insider threats.

Blockchain applications in grid cybersecurity

As the complexity of cybersecurity threats to energy infrastructures like the national power grids increases, the need for advanced security measures becomes paramount. Blockchain technology is emerging as a key player in enhancing the security, reliability, and resilience of these critical systems. The Pacific Northwest National Laboratory is leading the charge in embedding blockchain to protect the grid against both cyberattacks and physical threats, utilizing its distributed ledger for data integrity and smart contracts for automated system interactions.

PNNL’s use of blockchain helps ensure data integrity and transparency by maintaining a tamper-proof record of all grid operations, which is crucial for auditability and regulatory compliance. The technology’s decentralized nature reduces the risk of single points of failure, which can be exploited during cyberattacks, and supports quicker recovery from operational disruptions.

Blockchain’s application extends to enhancing operational efficiency through automated compliance and operational processes, significantly reducing the potential for human error. Furthermore, the cryptographic security provided by blockchain enhances overall grid cybersecurity, securing data transmitted across the grid and ensuring the integrity of communication among smart meters and IoT devices.

The vulnerabilities of smart grids, particularly in relation to interconnected smart meters and IoT devices, introduce significant security risks. Blockchain technology can mitigate these risks by securing data exchanges and authenticating user identities, thereby protecting the grid infrastructure from potential cyber threats.

Synergy between blockchain and SMRs

The advent of SMRs, such as the MK60 developed by Deep Atomic, marks a significant step forward in nuclear technology, particularly in its application to high-density energy consumers like data centers. SMRs are designed to be compact and scalable, providing a sustainable and efficient solution to meet the robust energy demands of modern digital infrastructures. Their smaller size compared to traditional nuclear reactors allows for easier siting and less complex logistical requirements, while their modularity supports phased construction strategies that can align more closely with actual energy demand growth.

Integrating blockchain technology with SMR operations enhances this next-generation nuclear solution by improving security, transparency, and efficiency at every stage of the nuclear power lifecycle. From tracking the origin and movement of nuclear materials to monitoring the operational status of reactors and managing the disposal of nuclear waste, blockchain provides a robust framework for managing the complex data involved in nuclear energy systems.

Blockchain’s role extends beyond material tracking; it also revolutionizes how energy produced by SMRs is managed and integrated into power grids. This capability is crucial for integrating SMR-produced energy with national grids or local microgrids, facilitating a more reliable and efficient energy distribution system. For example, the energy output from an SMR like the MK60 can be dynamically allocated across a microgrid, responding in real-time to changes in demand without compromising security or efficiency.

Moreover, the application of blockchain in this context supports compliance with international standards and regulatory requirements, providing a verifiable and tamper-proof record of compliance across the reactor’s operation. This not only aids in regulatory reporting and reduces administrative burdens but also enhances public and stakeholder trust in SMR technology as a safe and sustainable energy source.

Blockchain’s distributed ledger technology also allows for the implementation of smart contracts, which can automate many of the operations associated with energy distribution, such as dynamic pricing, fault management, and the activation of backup systems. This automation can help to optimize the operational efficiency of SMRs, reducing the potential for human error and increasing the responsiveness of the system to changes in supply and demand.

Global adoption by tech giants

As the digital economy expands, leading global technology firms such as Microsoft, Google, and Amazon face increasing demands for sustainable and reliable energy sources to power their extensive data centres and cloud services. To address these challenges, these tech giants are progressively turning to nuclear power, specifically leveraging SMRs to ensure a stable and continuous energy supply. SMRs represent a promising advancement in nuclear technology due to their smaller size, reduced waste, and enhanced safety features compared to traditional nuclear reactors.

The integration of blockchain technology with SMR operations marks a significant innovation in this sector. Blockchain plays a critical role in managing and tracking the lifecycle of nuclear energy—from fuel production and energy generation to waste handling and decommissioning. By recording every transaction on a secure and immutable ledger, blockchain technology enhances the security and transparency of nuclear energy management. This capability is crucial for tech companies committed to sustainability and responsible energy use, as it provides verifiable proof of where and how energy is produced and utilized.

For instance, Microsoft has signed agreements to reboot old nuclear facilities and develop new ones, using blockchain to monitor and manage the energy produced. Google has also entered into partnerships to utilize blockchain to track energy usage and production in its data centers powered by newly developed nuclear technologies. Meanwhile, Amazon is exploring similar initiatives, aiming to power upcoming data centers with nuclear energy that is meticulously tracked and managed via blockchain systems.

These initiatives are part of a broader strategy to meet increasingly stringent global carbon reduction targets. The use of SMRs, complemented by blockchain’s oversight, allows these companies not only to enhance their operational efficiencies but also to substantiate their claims of using clean energy. This dual approach not only supports their sustainability goals but also helps maintain reduced carbon footprints, setting a benchmark in the tech industry for energy management.

Moreover, the application of blockchain in nuclear energy management by these tech giants fosters greater regulatory compliance and public trust. By ensuring that energy sourcing and waste management are conducted transparently and securely, blockchain technology mitigates risks associated with nuclear energy, thus enhancing its acceptance and feasibility as a sustainable energy solution.

Blockchain technology’s role in nuclear security and energy management is multifaceted and expanding. By providing an unalterable record of nuclear material movements and energy transactions, blockchain technology not only enhances the security of sensitive materials but also promotes operational transparency. As this technology continues to mature, its integration into nuclear security operations and energy management systems is expected to yield significant benefits, promoting not only safety and compliance but also supporting the global transition towards more sustainable energy solutions. This integration represents a critical step forward in addressing some of the most pressing challenges in global energy management and nuclear nonproliferation.
