UK Office for Nuclear Regulation contributes to IAEA regulatory cooperation toolkit for advanced reactors
The International Atomic Energy Agency (IAEA) recently published the Nuclear Harmonization and Standardization Initiative (NHSI) Regulatory Cooperation Toolkit. The UK Office for Nuclear Regulation (ONR) played a significant role in the development of this toolkit, which is designed to support cooperation among national nuclear regulators in the review of advanced reactor technologies. The toolkit is one of the key outputs of Phase 2 of the NHSI (2025–2026), developed jointly by multiple regulators participating in the NHSI Regulatory Track and the Small Modular Reactor (SMR) Regulators' Forum. The toolkit provides practical guidance, templates, and methodologies to help regulators conduct collaborative reviews, leverage existing regulatory assessment outcomes, and address...
