Singapore Nuclear Research and Safety Institute

The Singapore Nuclear Research and Safety Institute (SNRSI) is an NUS-based national research institute for nuclear science and safety. On 11 July 2025, Singapore elevated the earlier Singapore Nuclear Research and Safety Initiative into a full-fledged institute and opened a purpose-built facility at the National University of Singapore (NUS) (National Environment Agency, 11 July 2025). SNRSI builds expertise that Singapore can use to assess changing nuclear technologies and respond to regional radiological risks; its establishment is not a decision that Singapore has approved a nuclear power plant.

Why Singapore maintains nuclear expertise

Singapore's policy is to keep its energy options open while assessing nuclear technologies against safety, reliability, affordability, and environmental sustainability in the local context (Ministry of Trade and Industry, accessed 19 August 2026). MTI states that conventional nuclear power plants were assessed as unsuitable for Singapore in an earlier pre-feasibility study, while advanced designs continue to evolve. SNRSI therefore supports evidence and technical capability for evaluating options and regional developments. It also helps Singapore prepare for the consequences of a radiological emergency elsewhere in the region. Nuclear research capacity is consequently both an energy-policy capability and a civil-protection capability, not an announcement of imminent domestic generation.

Research scope and national role

SNRSI coordinates research in nuclear safety, radiobiology, radiochemistry, and nuclear policy, working with international partners and research performers in fields such as mechanical engineering and materials science (National Environment Agency, 11 July 2025). Its facilities support reactor-safety analysis, radionuclide dispersion, radiobiology, radiochemistry, nuclear-policy research, and public education. NUS describes SNRSI as the research arm of the Nuclear Safety Research and Education Programme (NSREP), which was approved in 2013 and funded by the National Research Foundation (NRF) (NUS, accessed 19 August 2026). The institute is therefore distinct from the National Environment Agency (NEA): NEA remains Singapore's regulatory authority for radiation safety and environmental protection, while SNRSI is a research and capability-building institute. The new facility also houses NEA scientific laboratories, allowing research and monitoring expertise to be co-located.

Funding, talent and regional cooperation

The 2025 upgrade included a S$66 million grant under Singapore's Research, Innovation and Enterprise plan for the next bound of nuclear-safety research (National Environment Agency, 11 July 2025). This grant is programme-level research support, not a household subsidy or a commitment to construct a reactor. SNRSI plans to grow its expert pool from about 50 people to 100 by 2030, while building partnerships and participating in regional forums such as the ASEAN Network on Nuclear Power Safety Research (National Environment Agency, 11 July 2025). The intended outcome is a durable Singapore capability to analyse reactor designs, radiation pathways, environmental effects, and policy choices, including cooperation with international technical and scientific platforms.
