Getting Nuclear-ready: What Singapore’s IAEA Infrastructure Review Could Unlock for Future Atomic Options (Singapore IAEA Nuclear Infrastructure Review 2026)

Singapore is preparing for an International Atomic Energy Agency (IAEA) assessment in 2027 to evaluate whether it has the institutional, technical, and regulatory foundations to make an informed decision on nuclear energy deployment. Prime Minister Lawrence Wong has stressed that this step is not a decision to deploy nuclear energy. It is a structured readiness check. Safety is framed as the central constraint. Wong said Singapore is “a small and densely populated city-state” with “no margin for error,” and that Singapore must be confident not only in technology, but also in the supporting ecosystem, including regulation, security, emergency response, and waste management.

The review is the IAEA’s Integrated Nuclear Infrastructure Review, known as INIR, and Singapore will start with Phase 1 of three phases. Government agencies described INIR as an independent and voluntary IAEA assessment for countries considering embarking on or expanding a nuclear power programme, and as a way to ensure national infrastructure for safe, secure, and sustainable nuclear power is developed in a responsible and orderly manner. The assessment Singapore is embarking on sits within the IAEA “Milestones Approach,” a phased framework that can take more than 10 to 15 years, and which reflects international best practices shaped by decades of experience.

What the IAEA Will Examine, and Why Timing Matters

Singapore’s Phase 1 readiness assessment will examine 19 infrastructure areas. Reported examples include nuclear safety, emergency planning and preparedness, radioactive waste management, regulatory frameworks, and grid readiness. The point is not to chase “international approval,” but to identify blind spots early, including those local agencies may overlook over time, according to a forum reply by Energy Market Authority and National Environment Agency officials. The Straits Times also notes that at every phase the IAEA provides recommendations across these infrastructure issues, and that the mission can provide objective feedback to identify gaps and prioritise future actions.

Timeframes are a recurring theme in how Singapore is presenting this work. Wong said the preparatory process and actual infrastructure development can take “well over 15 years” based on other countries’ experience. The Straits Times similarly cited the IAEA’s global experience that moving from initial Phase 1 planning to construction and operation of a nuclear power plant takes at least 15 years. In this context, an assessment that starts in 2027 is framed as early groundwork, with a CNA report stating the assessment is expected to be completed by 2028. Singapore also said it intends to share the results of the INIR mission to keep the public informed.

The policy conversation is also being shaped by Singapore’s unique constraints and energy concerns. One report noted Singapore has studied nuclear energy for more than a decade, while rising electricity demand, energy security concerns, and growing regional interest in advanced nuclear technologies are bringing the issue back into focus. The government has increasingly pointed to small modular reactors (SMRs) as a potentially more suitable option for land-constrained Singapore, but the public messaging remains consistent: Phase 1 is not an official “green light” from the IAEA, and it is not a commitment to build. For readers tracking the Singapore IAEA nuclear infrastructure review 2026 topic, the key takeaway is that the country is building the capability to evaluate nuclear options methodically, with stringent safety requirements and a strong safety culture emphasized throughout.
