The Man Guiding Singapore’s Nuclear Future: Professor Laurence Williams and His Impact on the Republic’s Energy Strategy

A Pivotal Appointment at a Critical Juncture

When Professor Laurence Williams was appointed chairman of Singapore’s Nuclear Safety Advisory Panel in 2025, it marked more than just another accolade in a distinguished career. It represented Singapore’s most serious signal yet that nuclear energy had moved from theoretical consideration to practical planning. For a nation that has historically prided itself on being risk-averse and meticulously prepared, bringing in one of the world’s most experienced nuclear safety experts suggests the Republic is laying groundwork for what could be the most consequential energy decision in its history.

The timing is no coincidence. As Singapore grapples with the dual imperatives of energy security and climate commitments, and as five neighboring ASEAN nations race toward their own nuclear programs, the appointment of Williams—with his half-century of international nuclear experience—signals that Singapore is moving beyond capability-building into serious strategic planning.

The Weight of Experience: Understanding Williams’ Credentials

Five Decades at the Pinnacle of Nuclear Regulation

Professor Williams’ 50 years in the nuclear industry is not merely a measure of time—it represents an unparalleled span of experience across the entire evolution of modern nuclear safety thinking. His career has straddled the transformative periods following Three Mile Island (1979), Chernobyl (1986), and Fukushima (2011)—the three accidents that fundamentally reshaped global nuclear safety standards and public perception.

This chronological breadth means Williams has witnessed firsthand how the nuclear industry has evolved from its early, more cavalier days to today’s defense-in-depth philosophy and safety culture paradigm. He understands not just contemporary best practices, but the hard-won lessons that produced them—invaluable knowledge for a country starting from scratch.

Her Majesty’s Chief Inspector: What This Role Entailed

Williams’ position as Britain’s Chief Inspector of Nuclear Installations was one of the most powerful regulatory posts in the nuclear world. The UK’s Office for Nuclear Regulation oversees one of the world’s oldest and most complex nuclear estates, including:

• Commercial power reactors across multiple generations of technology
• Nuclear submarines and naval propulsion—Britain maintains a continuous at-sea nuclear deterrent
• Nuclear fuel cycle facilities, including enrichment and reprocessing
• Decommissioning operations at legacy sites dating back to the 1940s
• New build programs, including assessment of novel reactor designs

As Chief Inspector, Williams held statutory powers to shut down facilities, prosecute operators, and set binding safety requirements. This wasn’t advisory work—it was frontline regulatory decision-making with direct consequences for national energy security, defense capabilities, and public safety.

For Singapore, this experience is invaluable. Williams doesn’t just understand nuclear safety in theory; he’s made the tough calls when economic pressures, political considerations, and safety imperatives collided.

Defence Nuclear Safety Committee: The Hidden Dimension

Williams’ chairmanship of Britain’s Defence Nuclear Safety Committee adds a dimension that few nuclear advisors possess: understanding of military nuclear operations and the unique challenges they present.

Naval nuclear propulsion operates under constraints that civilian power plants never face:

• Reactors must function reliably in combat conditions
• Space and weight limitations demand compact, high-performance designs
• Crew safety in confined submarine environments
• Security considerations that exceed civilian requirements
• Dual-use technology concerns and proliferation risks

For Singapore—a small nation with limited land, maritime borders, and significant security considerations—this expertise in space-constrained, high-security nuclear operations is directly relevant. If Singapore pursues small modular reactors or offshore platforms, many design and operational challenges will parallel those of naval nuclear programs more closely than conventional land-based plants.

International Atomic Energy Agency: Shaping Global Standards

Williams’ role as chairman of the Commission on Safety Standards at the International Atomic Energy Agency (IAEA) from 2000 to 2005 placed him at the heart of global nuclear governance. The IAEA Safety Standards form the foundation of nuclear regulation worldwide—they’re the templates that nations use to build their own regulatory frameworks.

During Williams’ tenure, the IAEA was digesting lessons from Chernobyl and developing the safety culture concept that now dominates nuclear thinking. His leadership helped shape standards that are now implemented across 30+ countries with nuclear power programs.

For Singapore, having someone who literally wrote the international rulebook means the Republic can develop regulations that are not just compliant with global standards, but informed by the thinking behind those standards. Singapore won’t be copying and pasting generic requirements—it will be adapting principles with understanding of their purpose and flexibility.

European Nuclear Society: Continued Influence

Williams’ current position on the High Scientific Council of the European Nuclear Society keeps him connected to cutting-edge developments in nuclear technology and policy. Europe is currently experiencing a nuclear renaissance, with France doubling down on nuclear expansion, the UK advancing new builds, and even nuclear-skeptic nations reconsidering their positions due to energy security concerns following the Ukraine conflict.

This ongoing engagement means Williams brings current, not historical, expertise. He’s not advising Singapore based on 1990s thinking—he’s plugged into contemporary debates about advanced reactors, small modular reactors, fusion prospects, and the integration of nuclear power with renewable energy systems.

Why Williams’ Appointment Matters Profoundly for Singapore

1. Credibility in a Skeptical Region

Nuclear energy carries unique baggage in Asia. The Fukushima disaster occurred just 5,300 kilometers from Singapore, close enough that many Singaporeans remember the visceral fear, the radiation plume maps, and the images of a technologically advanced nation struggling to control a nuclear crisis.

Public acceptance—what Williams calls the “social licence”—will be Singapore’s highest hurdle. Having an advisor with unimpeachable credentials helps in multiple ways:

International reassurance: Singapore’s neighbors will be watching. Malaysia, just across the Causeway, will scrutinize any Singaporean nuclear plans. Having Williams involved signals that Singapore is pursuing nuclear energy with the highest standards, not cutting corners.

Domestic confidence: For Singaporean citizens understandably nervous about nuclear power, knowing that one of the world’s foremost nuclear safety experts is guiding policy provides reassurance. Williams’ reputation is his bond—he has nothing to gain and everything to lose by endorsing unsafe approaches.

Institutional gravitas: When Singapore inevitably faces difficult decisions—siting controversies, technology choices, cost-benefit debates—Williams’ presence elevates the discussion. His judgment carries weight that can help navigate politically charged decisions.

2. Avoiding Costly Mistakes Through Institutional Memory

The nuclear industry is littered with expensive mistakes that nations made by not fully understanding the sector’s complexities:

Finland’s Olkiluoto-3 reactor, originally budgeted at €3 billion, ended up costing over €11 billion and was 12 years late. The root causes included inadequate regulatory preparation, underestimation of safety requirements, and poor understanding of nuclear construction complexities.

The UK’s Hinkley Point C has faced massive cost overruns partly because the country had lost nuclear construction capability during its “nuclear gap” years and had to relearn institutional knowledge.

The United States has struggled with new nuclear builds at Vogtle and Summer, with Summer ultimately abandoned after $9 billion spent, largely due to loss of nuclear construction expertise.

Williams’ experience helps Singapore avoid these pitfalls. He knows:

• Which regulatory approaches work and which create bottlenecks
• How to structure operator-regulator relationships
• What technical capabilities must be developed versus what can be contracted
• How long realistic timelines actually are
• Where hidden costs typically emerge

For a small nation with limited margin for error, this knowledge is worth its weight in enriched uranium.

3. Technology-Agnostic Advisory: Avoiding Vendor Capture

One risk facing any nation entering the nuclear sector is “vendor capture”—where the country becomes overly dependent on or influenced by a particular reactor vendor or technology provider. This can lead to:

• Lock-in to potentially suboptimal technologies
• Reduced negotiating leverage on costs
• Dependency on foreign supply chains
• Vulnerability to geopolitical pressures

Williams’ breadth of experience across multiple reactor types, national programs, and regulatory philosophies makes him uniquely positioned to provide technology-agnostic advice. He’s not beholden to any vendor or national program. Whether Singapore considers:

• South Korean APR-1400s (proven technology, competitive pricing)
• American NuScale or other SMRs (advanced but unproven at scale)
• French EPRs (high power output but construction challenges)
• Chinese Hualong One (cost-effective but geopolitical considerations)
• UK Rolls-Royce SMRs (naval heritage, modular construction)

Williams can evaluate each on technical and safety merits without bias. His British background also positions him as relatively neutral in the ongoing US-China technology competition that will inevitably influence Singapore’s choices.

4. Building Singapore’s Nuclear Intelligence Capability

Even if Singapore ultimately decides against deploying nuclear power, Williams emphasized the importance of being an “intelligent observer” of regional developments. This is crucial because:

Five ASEAN neighbors (Vietnam, Indonesia, Philippines, Malaysia, Thailand) are pursuing nuclear programs. Malaysia and Indonesia’s nuclear ambitions have direct implications for Singapore—a major accident at a Malaysian plant could affect Singapore despite no Singaporean nuclear deployment.

Emergency preparedness: Singapore needs capability to respond to regional nuclear incidents. This requires understanding of reactor types, accident progression, radioactive dispersion, and protective measures.

Economic competitiveness: If neighbors gain access to cheap, reliable nuclear power while Singapore relies on more expensive alternatives, it could affect economic competitiveness—a concern for a nation dependent on attracting investment.

Regional influence: By developing nuclear expertise, Singapore positions itself as a potential hub for nuclear safety, training, and regulatory services in ASEAN—a soft power opportunity.

Williams’ role is to help Singapore build this intelligence capability, whether or not the Republic ultimately deploys its own reactors.

5. Navigating the Offshore Nuclear Dilemma

Williams’ comments on offshore nuclear deployment reveal the sophisticated thinking Singapore is applying to its unique constraints. The offshore option is attractive because:

• Distance provides psychological comfort to a dense population
• Water cooling is readily available
• Security perimeters are easier to establish
• Tsunami risk is lower for Singapore than for coastal land sites

But Williams identified key challenges:

Workforce isolation: Operating a nuclear plant requires 24/7 staffing by highly trained personnel. An offshore platform means staff either commute daily (expensive, weather-dependent) or stay on-site for extended periods (quality of life issues, retention challenges). Britain’s offshore oil platforms show these challenges are manageable but significant.

Subsea cables: Singapore’s entire electricity grid would depend on undersea cables from platform to mainland. These are vulnerable to anchor strikes, subsea landslides, and sabotage. Redundancy is essential but expensive.

Extreme weather: While Singapore doesn’t face hurricanes or tsunamis at the same intensity as some regions, intense tropical storms and rising sea levels pose challenges. Climate change makes long-term weather prediction more uncertain.

Construction complexity: Building offshore is inherently more difficult and expensive than land-based construction. Supply chain logistics, weather delays, and specialized equipment all add costs.

Williams’ experience with Britain’s offshore industry (oil, gas, and wind) and naval nuclear programs makes him uniquely qualified to help Singapore assess these trade-offs realistically.

The “Social Licence” Challenge: Williams’ Most Critical Contribution

Perhaps Williams’ most important insight is his emphasis on the “social licence”—the need for public acceptance before technical deployment can proceed. His statement that “it doesn’t matter how good your reactor design is and how well you can operate it—if your local public doesn’t want it for whatever reason, then it’s not going to happen” reflects hard-won wisdom.

Learning from European Examples

Williams draws on European experience where public opposition has derailed nuclear programs:

Germany’s Energiewende: Following Fukushima, Germany decided to phase out nuclear power entirely despite having modern, safe reactors and despite the climate implications. This was fundamentally a political decision driven by public fear, not technical assessment. The result: increased reliance on coal in the short term and higher electricity costs.

Italy’s referendum: Italy shut down its nuclear program following Chernobyl and, after reconsidering nuclear in the 2000s, held a referendum in 2011 (post-Fukushima) that decisively rejected nuclear power. Technical arguments about safety and climate were overwhelmed by public emotion.

Switzerland’s gradual phase-out: Following Fukushima, Switzerland voted to gradually phase out nuclear, despite nuclear providing over one-third of its electricity and having an excellent safety record.

These examples demonstrate that technical excellence is necessary but insufficient. Public confidence must be earned through:

Transparency and Openness

Williams advocates maximum transparency about technology choices, safety measures, operational details, and regulatory oversight. This contrasts with the historical nuclear industry tendency toward secrecy and top-down decision-making.

For Singapore, this means:

• Public consultations before technology and siting decisions
• Open regulatory processes where safety assessments are published
• Accessible public education about radiation, reactor operations, and emergency procedures
• Honest communication about risks, costs, and uncertainties

Singapore’s political culture traditionally favors technocratic decision-making with limited public input. Nuclear power may require adapting this approach to build the necessary social licence.

The Three-Pillar Model: Williams’ Framework for Public Confidence

Williams outlined three measures for improving public perception, drawn from British experience:

1. Technically competent licensed operator: The entity running the plant must demonstrably know what it’s doing. This requires:

• Proven operational track record (challenging for Singapore as a newcomer)
• Rigorous training and qualification programs
• Safety culture embedded at all levels
• Financial stability to maintain high standards

Singapore would likely need to partner with an experienced international operator initially, gradually building domestic capability.

2. Independent internal assurance: Within the operating organization, there must be a team independent of production pressures focused solely on safety assurance. Williams describes this as having both “the chief nuclear officer responsible for producing as much power as he could” and “the director of safety and assurance there giving the view of safety” at the board level.

This internal tension—production versus safety—ensures that commercial pressures don’t compromise safety standards. It’s a model proven across high-reliability organizations from aviation to petrochemicals.

3. External statutory regulator: An independent regulator acting on behalf of the public with real powers to enforce safety requirements. This regulator must be:

• Genuinely independent from political and commercial pressures
• Adequately resourced to conduct rigorous oversight
• Staffed by experts who can challenge the operator
• Transparent in decision-making
• Accountable to the public

For Singapore, establishing this regulatory function at the National Environment Agency represents a significant undertaking. The NEA must develop expertise in nuclear safety, security, safeguards, and emergency preparedness essentially from scratch—though Williams’ role is precisely to guide this development.

Singapore’s Unique Context: What Makes Williams’ Advice Especially Relevant

Space Constraints and High-Density Living

Singapore is one of the most densely populated nations on Earth, with over 8,000 people per square kilometer. This creates challenges few other nuclear nations face:

Emergency evacuation: Standard nuclear emergency planning uses concentric evacuation zones (typically 10km and 50km radii). In Singapore, a 10km radius from any plausible reactor site would encompass hundreds of thousands of people, potentially including critical infrastructure like Changi Airport or major industrial estates.

Williams’ experience with the UK’s dense industrial regions and his understanding of risk-informed decision-making help Singapore think through these challenges realistically. Should Singapore apply more stringent safety requirements to compensate for high population density? Should it restrict reactor types to those with enhanced passive safety features? These are questions Williams is uniquely positioned to help answer.

Water Scarcity and Cooling Requirements

Nuclear plants require massive amounts of cooling water. Singapore’s water scarcity adds complexity:

Seawater cooling is the obvious solution, but this requires careful management of thermal discharge to protect marine ecosystems. Singapore’s busy shipping channels and important fisheries make this more complex than for nations with extensive coastlines.

Closed-loop cooling reduces water consumption but increases cost and complexity, and still requires some water makeup.

Desalination integration: An intriguing possibility is co-locating nuclear plants with desalination facilities, using waste heat for desalination. This could improve overall efficiency and help address Singapore’s water security. Williams’ systems-level thinking across energy and water sectors positions him to evaluate such integrated approaches.

Geopolitical Sensitivity

Singapore’s geopolitical position makes nuclear deployment uniquely sensitive:

Regional reassurance: Any Singaporean nuclear program must reassure neighbors, particularly Malaysia and Indonesia, that it poses no threat. Williams’ international stature and emphasis on transparency help in this diplomatic dimension.

Supply chain dependencies: Singapore would depend on foreign suppliers for fuel, technology, and potentially operations. Williams’ understanding of international nuclear cooperation agreements, safeguards, and supply chain security helps Singapore navigate these dependencies.

Non-proliferation commitments: As a non-nuclear weapons state party to the Non-Proliferation Treaty, Singapore must demonstrate that any civilian nuclear program is purely for peaceful purposes. Williams’ experience with IAEA safeguards is directly applicable.

Economic Considerations

Singapore’s high land costs and labor costs make nuclear economics different from other nations:

Construction costs: Land acquisition and construction labor in Singapore are among the world’s most expensive. This favors technologies that minimize land footprint and construction time—potentially arguing for advanced SMRs over conventional large reactors.

Operational costs: Singapore’s high wages mean operational costs will be higher than in nations with cheaper labor. This favors highly automated reactor designs with minimal staffing requirements.

Financing costs: Singapore’s strong credit rating gives it advantageous borrowing costs, potentially offsetting some of the high construction costs. Williams’ understanding of nuclear project finance helps Singapore structure projects to minimize cost of capital.

Climate and Environmental Factors

Singapore’s tropical climate creates unique considerations:

Corrosion: High humidity and salt air accelerate corrosion of nuclear facilities. Design and materials selection must account for this aggressive environment.

Biofouling: Tropical waters mean rapid biofouling of cooling water intakes, requiring more intensive maintenance.

Rising sea levels: Any coastal or offshore facility must be designed for sea level rise over a 60-80 year operational lifetime. Williams’ forward-looking perspective helps ensure designs account for climate change impacts.

The Strategic Value of Williams’ Independence

A critical but often overlooked aspect of Williams’ appointment is his independence. As a British expert with no commercial ties to reactor vendors or national interests in Singapore’s decisions, he can provide genuinely impartial advice.

Avoiding the Pitfalls of Conflicted Advice

Many nations entering the nuclear sector receive advice from:

• Reactor vendors seeking to sell their technology
• Nuclear-operating nations promoting their own regulatory approaches and technologies
• International consultants who may have hidden commercial relationships

This advice, while sometimes valuable, is inevitably colored by commercial or national interests. The advisor from France will naturally favor French EPR technology; the American consultant may steer toward US designs; the Korean advisor will promote Korean reactors.

Williams owes nothing to any vendor or national program. His reputation is built on sound judgment, not on promoting particular technologies or approaches. This independence is invaluable for Singapore in making clear-eyed decisions.

The Long-Term Relationship

Williams’ appointment runs through 2027, but his influence will extend far beyond. He is helping Singapore build institutional knowledge and establish frameworks that will guide nuclear policy for decades. The regulatory philosophy, safety culture principles, and decision-making processes being established now will shape Singapore’s nuclear future—if it chooses to pursue one—for generations.

Conclusion: The Right Expert at the Right Time

Professor Laurence Williams’ appointment as chairman of Singapore’s Nuclear Safety Advisory Panel is far more significant than a typical advisory role. It represents:

A signal of seriousness: Singapore doesn’t bring in advisors of Williams’ caliber for theoretical exercises. His appointment indicates nuclear energy has moved to serious consideration.

A commitment to excellence: By choosing one of the world’s most experienced and respected nuclear safety experts, Singapore signals it will pursue nuclear energy—if at all—only to the highest international standards.

A strategic investment: The knowledge and frameworks Williams helps establish will benefit Singapore whether or not it ultimately deploys nuclear power, by building capability to understand and respond to regional nuclear developments.

A model for other nations: Singapore’s methodical, expertise-driven approach to nuclear decision-making, exemplified by Williams’ role, offers a template for other nations considering nuclear energy.

For Singapore, the path to nuclear energy—if taken—will be long, expensive, and fraught with challenges. But with Williams’ guidance, the Republic has positioned itself to make informed decisions based on the deepest possible understanding of nuclear technology, safety, regulation, and public acceptance.

Whether Singapore ultimately builds nuclear reactors or remains an “intelligent observer,” the investment in Williams’ expertise represents strategic foresight that will pay dividends for decades. In the complex, high-stakes domain of nuclear energy, having the right expert at the right time isn’t just valuable—it could be the difference between success and failure, between public confidence and public rejection, between energy security and energy vulnerability.

Singapore’s nuclear future remains undecided, but its approach to making that decision—exemplified by Williams’ appointment—demonstrates the thoughtful, rigorous, and internationally-informed decision-making that has characterized the Republic’s approach to existential challenges throughout its history.

Singapore’s Strategic Foray into Nuclear Energy: Institutional Reorganization, Capability Building, and the Exploration of Advanced Technologies

Abstract: Singapore, a small island nation acutely vulnerable to climate change and dependent on imported fossil fuels, faces significant energy security and sustainability challenges. This paper analyzes the recent institutional reorganization within the Singaporean government, specifically the establishment of dedicated nuclear teams at the Energy Market Authority (EMA) and the National Environment Agency (NEA). Following Prime Minister Lawrence Wong’s announcement in Budget 2025, these developments signify a strategic and intensified commitment to rigorously assess the feasibility and safety of advanced nuclear energy technologies, such as Small Modular Reactors (SMRs), for future power generation. While Singapore has not yet made a definitive decision on nuclear energy deployment, this paper argues that the proactive development of expert capabilities and regulatory frameworks marks a critical phase in its comprehensive energy diversification strategy.

Keywords: Singapore, Nuclear Energy, Energy Market Authority (EMA), National Environment Agency (NEA), Small Modular Reactors (SMRs), Energy Security, Climate Change, Regulatory Framework, Capability Building.

1. Introduction

Singapore’s rapid economic growth and dense urban environment present a unique and complex energy landscape. As a non-resource-rich nation, it relies heavily on imported natural gas, making it susceptible to global energy market fluctuations and geopolitical instability (IEA, 2023). Simultaneously, Singapore is deeply committed to achieving its climate change targets, including reaching net-zero greenhouse gas emissions by 2050 (National Climate Change Secretariat, 2022). These dual pressures of energy security and sustainability necessitate a comprehensive and forward-thinking approach to its energy future.

In this context, nuclear energy has emerged as a potential long-term, low-carbon power source that could significantly diversify Singapore’s energy mix. While the nation has historically maintained a cautious stance due to its small land area and high population density, recent global technological advancements, particularly in advanced nuclear technologies like Small Modular Reactors (SMRs), have prompted a re-evaluation. This paper focuses on the critical institutional developments reported in October 2025, specifically the creation of dedicated nuclear energy teams within the Energy Market Authority (EMA) and the National Environment Agency (NEA). These developments, catalyzed by Prime Minister Lawrence Wong’s Budget 2025 speech, represent a pivotal strategic shift towards enhanced capability building and a thorough, evidence-based assessment of nuclear energy’s viability for Singapore.

2. Singapore’s Energy Imperatives and the Nuclear Option

Singapore’s energy policy is driven by a trilemma: energy security, economic competitiveness, and environmental sustainability (EMA, 2024). The nation’s reliance on natural gas for approximately 95% of its electricity generation, predominantly imported via pipelines and Liquefied Natural Gas (LNG) terminals, underscores a significant vulnerability (EMA, 2023). While solar energy deployment is increasing, land constraints severely limit its potential for large-scale baseload power generation. Alternative renewable sources like wind and hydropower are not viable options in Singapore’s geographical context.

Given these constraints, exploring options for baseload, low-carbon power is paramount. Nuclear energy, with its high power output, low operational carbon emissions, and high capacity factor, presents a compelling alternative. However, the decision to adopt nuclear power is fraught with complex challenges, including safety concerns, waste management, security risks, high capital costs, and the need for a robust regulatory framework and skilled workforce. The institutional restructuring and capability building described below are direct responses to the need for a comprehensive and informed assessment of these formidable factors.

3. The Strategic Shift: Government Reorganization for Nuclear Capability

In February 2025, Prime Minister Lawrence Wong announced in his Budget speech a significant government reorganization aimed at placing “greater emphasis” on capability building in nuclear energy. This announcement signaled a clear strategic intent: while a decision to deploy nuclear energy has not been made, Singapore is investing in the necessary expertise and infrastructure to thoroughly evaluate the option. This proactive approach distinguishes itself from a reactive consideration, demonstrating a commitment to long-term strategic energy planning.

The subsequent establishment of dedicated nuclear teams at the EMA and NEA, reported in October 2025, operationalizes this strategic directive. This institutional restructuring reflects a multi-faceted recognition:

Complexity of Nuclear Technology: Nuclear energy demands specialized technical, scientific, and regulatory expertise that cannot be developed overnight.
Breadth of Considerations: The assessment must encompass not only energy generation feasibility but also rigorous safety, security, and environmental protection protocols.
Proactive Planning: Building capabilities in advance allows for a more robust and credible decision-making process when the time comes.

This reorganisation demonstrates Singapore’s characteristic long-term strategic planning, prioritizing expert capacity building before making irreversible policy commitments (Koh & Tan, 2017).

4. Institutional Responsibilities and Capability Building

The creation of dedicated teams within EMA and NEA highlights the distinct, yet complementary, roles these agencies play in the comprehensive assessment of nuclear energy.

4.1. Energy Market Authority (EMA): Feasibility and Technology Assessment

The EMA, responsible for regulating Singapore’s electricity and gas industry and ensuring reliable energy supply, has formed a dedicated nuclear energy team. Its primary mandate is to “assess the feasibility of deploying advanced nuclear energy technologies for power generation in Singapore.” This involves a multi-pronged approach:

Technological Evaluation: The EMA team is actively conducting studies on advanced nuclear technologies, specifically mentioning Small Modular Reactors (SMRs). SMRs are of particular interest to Singapore due to their smaller physical footprint, modular construction which could reduce capital costs and construction times, inherent safety features (often passive safety systems), and potential for flexible deployment (World Nuclear Association, 2023). Their suitability for Singapore’s land constraints and demand profile makes them a key focus.
International Engagement and Learning: To build understanding and expertise, the EMA has undertaken site visits to countries with mature nuclear energy programmes, including the United States, Switzerland, and France. These visits facilitate direct engagement with operators, regulators, and research institutions, allowing Singapore to learn best practices, evaluate different technological approaches, and understand the operational realities and regulatory landscapes of established nuclear nations. This international benchmarking is crucial for an aspiring nuclear nation.
Economic and Grid Integration Analysis: While not explicitly stated in the provided text, the EMA’s mandate inherently includes assessing the economic viability, financing models, and the integration challenges and opportunities of nuclear power within Singapore’s existing grid infrastructure. This would involve detailed cost-benefit analyses, power system modeling, and considerations of market design.

4.2. National Environment Agency (NEA): Radiation and Nuclear Safety Regulation

The NEA, serving as Singapore’s national radiation and nuclear safety regulator, has established a nuclear safety team to “deepen expertise in nuclear safety, security and safeguards.” This proactive development of regulatory capacity is critical, as a robust and independent regulatory body is foundational for any nuclear programme. NEA’s responsibilities extend to protecting public health and the environment from the risks associated with radiation.

Key activities undertaken by the NEA nuclear safety team include:

Regulatory Framework Development: The team’s expertise building will contribute to developing and refining the comprehensive regulatory framework necessary for nuclear power. This includes licensing procedures, safety standards, security protocols, emergency preparedness plans, and safeguards against nuclear proliferation (IAEA, 2022).
Radiation Monitoring Programme: The NEA already maintains an extensive ambient radiation monitoring programme across Singapore. This network comprises 40 air and water radiation monitoring stations, specifically equipped to measure a range of radiological parameters, such as radionuclide concentrations in the environment. This existing baseline data and continuous monitoring capability are invaluable. They provide:
Environmental Baseline: Essential pre-operational data against which any future radiological changes could be measured.
Early Detection: The ability to detect and quantify any abnormal radiological releases, enhancing public safety and confidence.
Public Assurance: Demonstrating a commitment to transparency and continuous environmental surveillance.
Safety Culture and Training: Deepening expertise in nuclear safety inherently involves fostering a strong safety culture and developing specialized training programmes for future nuclear professionals and first responders, even at this exploratory stage.

5. Advanced Nuclear Technologies: A Focus on Small Modular Reactors (SMRs)

The EMA’s specific focus on SMRs warrants further discussion. SMRs represent a paradigm shift from traditional large-scale nuclear reactors, offering several potential advantages particularly relevant to Singapore’s unique context:

Smaller Footprint: SMRs require significantly less land area compared to conventional gigawatt-scale reactors, which is a critical advantage for densely populated Singapore.
Enhanced Safety: Many SMR designs incorporate advanced passive safety systems that rely on natural forces like gravity or convection, rather than active components, enhancing safety and reducing the likelihood of severe accidents (NuScale Power, 2023).
Modularity and Scalability: Their modular design allows for factory fabrication and easier transportation, potentially reducing construction times and costs. This also enables incremental capacity expansion, matching future energy demand more precisely.
Flexibility: SMRs can be deployed in various configurations, potentially closer to demand centers or even for non-electric applications such as district heating or industrial process heat, offering greater energy system flexibility.

While SMRs offer promising solutions, challenges remain, including their economic competitiveness compared to large reactors (due to loss of economy of scale, though this is debated by proponents on a levelized cost of energy basis), first-of-a-kind engineering risks, and the need for specific regulatory adaptation (OECD-NEA, 2022). Singapore’s studies will undoubtedly delve into these aspects.

6. Challenges and Considerations

Despite the proactive steps, Singapore’s potential adoption of nuclear energy faces several significant challenges:

Land Scarcity for Siting and Waste Management: Even with SMRs, land for reactors and potential long-term waste storage remains a critical concern for a small island state.
Public Perception and Acceptance: Building and maintaining public trust and acceptance will be crucial. Transparent communication, robust safety assurances, and public education campaigns will be vital.
Regulatory Framework Maturation: While the NEA is building capacity, establishing a fully mature and internationally credible nuclear regulatory framework will be a multi-year undertaking, requiring continuous international collaboration and rigorous standards.
Talent Development: Developing a specialized workforce across all facets of a nuclear energy programme – from engineering and operations to safety and regulation – will require substantial investment in education and training.
Geopolitical and Security Concerns: Securing fuel supply, managing spent fuel, and ensuring robust physical and cyber security measures will necessitate strong international partnerships and adherence to non-proliferation treaties.
Financial Implications: Nuclear projects are characterized by high upfront capital costs, requiring innovative financing models and significant government commitment.

7. Conclusion

The establishment of dedicated nuclear teams at Singapore’s Energy Market Authority (EMA) and National Environment Agency (NEA) marks a significant and strategic commitment to a thorough, evidence-based exploration of nuclear energy. Driven by national energy security imperatives and ambitious climate change targets, Singapore is proactively building the necessary institutional capabilities and expert knowledge to assess the complex technical, safety, economic, and environmental aspects of advanced nuclear technologies, particularly Small Modular Reactors.

While a definitive decision on nuclear energy deployment has yet to be made, these governmental reorganizations underscore Singapore’s methodical approach to long-term strategic planning. The EMA’s focus on technological feasibility and international learning, complemented by the NEA’s emphasis on deepening regulatory expertise and maintaining robust environmental monitoring, collectively position Singapore to make an informed choice. The challenges remain substantial, but by laying this groundwork, Singapore is preparing itself to potentially harness nuclear energy as a vital component of a resilient, diversified, and sustainable energy future.

A Historic Agreement Crumbles

On October 8, 2025, Russia’s State Duma took a decisive step toward completely withdrawing from the Plutonium Management and Disposition Agreement (PMDA), marking another critical breakdown in the post-Cold War nuclear arms control architecture. This move, while building on Russia’s 2016 suspension of the agreement, represents a formal severing of ties on a pact that once symbolized cooperation between the world’s two largest nuclear powers.

The PMDA, signed in 2000 during a period of relative US-Russia cooperation, embodied the optimism of the post-Cold War era. Both nations committed to irreversibly disposing of 34 tonnes of weapons-grade plutonium each—material sufficient to construct approximately 17,000 nuclear warheads. The agreement was not merely symbolic; it addressed a genuine security concern: vast stockpiles of fissile material that were expensive to secure and posed proliferation risks in an era of terrorism and nuclear smuggling.

The Technical and Strategic Significance

The collapse of the PMDA carries implications far beyond diplomatic symbolism. Weapons-grade plutonium represents the most direct pathway to nuclear weapons capability. Each kilogram can produce one to two nuclear devices, and the 68 tonnes covered by the agreement (34 tonnes per country) represent an enormous potential arsenal.

The disposal methods outlined in the PMDA reflected different technical approaches but shared a common goal: irreversibility. Russia favored irradiating plutonium in fast-neutron reactors, which would generate electricity while rendering the material unsuitable for weapons. The United States initially planned to create mixed oxide (MOX) fuel, blending plutonium with uranium for use in civilian reactors.

However, Washington’s 2014 decision to abandon the costly MOX facility construction—instead opting for a dilute-and-dispose method—became a flashpoint. Russia argued this approach violated the agreement’s spirit because diluted plutonium could theoretically be reconcentrated, though this would be technically challenging and economically impractical. This disagreement exposed deeper trust deficits between the two powers.

The Cascading Collapse of Arms Control

Russia’s withdrawal from the PMDA must be understood within the broader disintegration of the nuclear arms control framework that has accelerated over the past decade:

2002: The United States withdrew from the Anti-Ballistic Missile (ABM) Treaty, enabling development of missile defense systems that Russia viewed as threatening its nuclear deterrent.

2019: Both nations withdrew from the Intermediate-Range Nuclear Forces (INF) Treaty amid mutual accusations of violations, ending restrictions on ground-launched missiles with ranges between 500 and 5,500 kilometers.

2023: Russia suspended participation in New START, the last remaining major nuclear arms control treaty, which limited deployed strategic nuclear warheads and delivery systems.

2025: Russia moves to formally withdraw from the PMDA, eliminating the final cooperative mechanism for reducing weapons-grade fissile material stockpiles.

This systematic dismantling leaves virtually no institutional framework governing the world’s two largest nuclear arsenals, which together comprise approximately 8,000 of the world’s 12,000+ nuclear warheads. The situation represents the most dangerous moment in nuclear relations since the height of the Cold War, with none of the communication channels and confidence-building measures that prevented catastrophe then.

Russia’s Stated Justifications: Unpacking the Rationale

Moscow’s official explanation cites “new anti-Russian steps” that fundamentally alter the strategic balance. While vague, this language encompasses several Russian grievances:

NATO Expansion: Russia has consistently opposed NATO’s eastward enlargement, viewing it as an existential threat. Finland’s 2023 accession and Sweden’s 2024 membership particularly alarmed Moscow, given their proximity to Russian territory and the strategic importance of the Baltic Sea.

Sanctions Regime: Western sanctions following Russia’s actions in Ukraine have grown increasingly comprehensive, targeting Russia’s defense industry, financial system, and technological access. Moscow views these as economic warfare incompatible with cooperative nuclear security.

Strategic Weapons Concerns: Russian officials frequently reference U.S. missile defense deployments in Europe, conventional precision-strike capabilities, and hypersonic weapons development as threats to Russia’s nuclear deterrent.

Perceived Inequality: Russia’s 2016 complaint that the United States changed disposal methods without approval reflects broader frustration about being treated as a junior partner rather than equal stakeholder.

These justifications blend legitimate security concerns with narrative crafting designed for domestic and international audiences. The timing—amid ongoing tensions over Ukraine, economic pressures, and ahead of potential U.S. political transitions—suggests strategic calculation beyond pure arms control considerations.

Global Implications: The Return of Nuclear Competition

The PMDA’s demise accelerates several troubling global trends:

Renewed Arms Racing: Without constraints, both nations can expand nuclear arsenals. Russia has already announced plans to deploy new strategic systems, while the United States pursues comprehensive nuclear modernization expected to cost over $1.5 trillion over 30 years.

Proliferation Risks: The loss of transparent, verified plutonium disposition increases risks. If weapons-grade material is not irreversibly disposed of, it could potentially be stolen, diverted, or used by other nations as justification for their own nuclear programs.

Third-Party Nuclear Powers: China is rapidly expanding its nuclear arsenal, with U.S. intelligence estimating it could possess 1,500 warheads by 2035. The U.S.-Russia arms control vacuum creates space for China to avoid constraints while modernizing, and may encourage other nuclear-armed states to enhance their capabilities.

Erosion of Non-Proliferation Norms: The Non-Proliferation Treaty (NPT) rests on a bargain: non-nuclear states forgo weapons in exchange for nuclear powers pursuing disarmament. The collapse of U.S.-Russia agreements undermines this bargain, potentially encouraging nuclear hedging or breakout by states like Iran, South Korea, or Japan.

Crisis Stability Concerns: Arms control agreements serve as crisis-management tools, providing communication channels and reducing uncertainty during tensions. Their absence increases miscalculation risks during confrontations.

Singapore’s Strategic Concerns: Small State in a Nuclear Shadow

While geographically distant from U.S.-Russia confrontation zones, Singapore faces significant implications from deteriorating nuclear relations:

Regional Security Architecture

Singapore’s security depends on a stable, rules-based international order. The breakdown of major power agreements threatens this foundation:

ASEAN Centrality at Risk: If great power rivalry intensifies, ASEAN’s ability to maintain centrality in regional security architecture weakens. Nuclear tensions between major powers could force Southeast Asian states into uncomfortable alignments.

South China Sea Tensions: Nuclear escalation risks in U.S.-China or U.S.-Russia relations could complicate already fraught South China Sea dynamics. If nuclear powers clash over Taiwan or other flashpoints, Singapore’s critical sea lanes become contested spaces.

Nuclear Weapons in the Region: The collapse of arms control may accelerate regional nuclear proliferation. If North Korea’s nuclear program remains unconstrained and other Asian powers (Japan, South Korea, Australia) reconsider their non-nuclear status, Southeast Asia’s security environment fundamentally transforms.

Economic Vulnerabilities

Singapore’s economy depends on global stability and open trade:

Trade Route Security: Approximately one-third of global trade passes through Southeast Asian waters. Nuclear tensions increase risks of conflict that could disrupt these vital arteries. Singapore’s port—the world’s second-busiest—would face severe impacts from any major power confrontation.

Energy Security: Singapore imports virtually all energy needs, relying on stable regional suppliers and global markets. Nuclear tensions could trigger energy price spikes, supply disruptions, or infrastructure targeting in conflict scenarios.

Financial Hub Status: Singapore’s position as a global financial center requires confidence and stability. Escalating nuclear risks increase market volatility, capital flight risks, and potential sanctions compliance complications as major powers weaponize economic tools.

Defense and Deterrence Calculations

Singapore’s defense planning must account for evolving nuclear dynamics:

U.S. Extended Deterrence: Singapore benefits indirectly from U.S. security presence in Asia-Pacific. If U.S.-Russia nuclear competition drains resources or attention from Asia, or if U.S. extended deterrence credibility erodes, Singapore’s security environment worsens.

Defense Modernization Pressures: Rising great power tensions may require enhanced defense capabilities, increased spending, and more sophisticated systems to maintain deterrence and defense in a more dangerous environment.

Cyber and Hybrid Threats: Nuclear-armed states increasingly employ cyber warfare, disinformation, and hybrid tactics below the nuclear threshold. Singapore must defend against these threats while avoiding escalation spirals.

Diplomatic Challenges

Singapore faces difficult diplomatic navigation:

Balanced Relationships: Singapore maintains relations with all major powers—the United States, China, and Russia. Intensifying nuclear competition pressures Singapore to choose sides, threatening its longstanding policy of not aligning with any great power.

Non-Aligned Stance: As a small state, Singapore has championed international law, multilateralism, and peaceful dispute resolution. The collapse of arms control undermines these principles, forcing Singapore to operate in a more anarchic international environment.

ASEAN Unity: Nuclear tensions may divide ASEAN members with different alignments and threat perceptions. Singapore’s diplomatic efforts to maintain ASEAN cohesion become more difficult as external pressures intensify.

What Singapore Can Do: Small State Agency

Despite its size, Singapore can take meaningful actions:

Diplomatic Engagement: Singapore can use its reputation for neutrality to facilitate dialogue, host negotiations, or propose confidence-building measures. Its chairmanship of various international forums provides platforms for advocacy.

Support for Multilateral Institutions: Singapore can champion strengthening the International Atomic Energy Agency (IAEA), reinvigorating the NPT review process, and supporting regional nuclear-weapon-free zones.

Track II Diplomacy: Singapore’s think tanks and academic institutions can convene unofficial dialogues between nuclear powers, exploring possibilities for risk reduction when official channels stall.

Regional Cooperation: Singapore can work with ASEAN partners to develop common positions on nuclear non-proliferation, advocate for reducing nuclear risks, and strengthen regional crisis communication mechanisms.

Resilience Building: Singapore can enhance national resilience through diversified supply chains, energy security investments, cyber defense capabilities, and civil defense preparedness.

Looking Ahead: A Precarious Future

The formal withdrawal from the PMDA removes the final cooperative pillar in U.S.-Russia nuclear relations. What emerges is a more dangerous world characterized by:

• Unlimited Nuclear Competition: No constraints on warhead numbers, delivery systems, or fissile material stockpiles
• Reduced Transparency: No verification regimes or mutual inspections to build confidence
• Increased Accident Risks: No communication protocols or crisis management tools
• Proliferation Pressures: Other states may pursue nuclear capabilities in a more permissive environment
• Conventional-Nuclear Linkage: Lower thresholds for nuclear use in regional conflicts

For Singapore, this represents a fundamental shift in the global security environment. The relative stability of the post-Cold War era, which enabled Singapore’s remarkable economic development and strategic positioning, is giving way to a more volatile, multipolar nuclear competition.

The question is not whether Singapore will be affected—it will be. The question is whether Singapore and other responsible nations can slow this deterioration, preserve what remains of the arms control architecture, and build new mechanisms for managing nuclear dangers in a more complex, multipolar world.

The stakes could not be higher. As two nuclear superpowers abandon the restraints that have prevented nuclear war for eight decades, all nations—large and small—must recognize that nuclear risks are not distant abstractions but immediate threats to the stability upon which modern prosperity depends.

Singapore’s response will test the agency of small states in an era of renewed great power competition. The city-state’s ability to navigate these treacherous waters while maintaining its principles, prosperity, and security will serve as a model—or cautionary tale—for similarly situated nations worldwide.
