Chapter 2: Introduction to Nuclear Safety
Evolution of IAEA requirements for the design of Nuclear Power Plants: from 50-C-D (1988) to SSR-2/1 (Rev. 1) (2016)
Current up-to-date IAEA requirements for the design of NPPs are contained in the IAEA Specific Safety Requirements No. SSR-2/1 (Rev.1), Safety of Nuclear Power Plants: Design (2016).
Safety Standards are generally revised every 8 years approximately, to keep pace with the increasing operational experience and associated evolving knowledge in all fields where IAEA Safety Standards are applicable (radioactive sources, nuclear power plants, research reactors, fuel cycle facilities, transport of radioactive materials).
Within this context, the SSR-2/1 (Rev. 1) is the fourth standard for the design of NPPs published in the last 30 years:
• IAEA Safety Standards Series No. 50-C-D, Code on the Safety of Nuclear Power Plants: Design (1988);
• IAEA Safety Standards Series No. NS-R-1, Safety of Nuclear Power Plants: Design (2000);
• IAEA Specific Safety Requirements No. SSR-2/1, Safety of Nuclear Power Plants: Design (2012);
• IAEA Specific Safety Requirements No. SSR-2/1 (Rev. 1), Safety of Nuclear Power Plants: Design (2016).
Requirements introduced in SSR-2/1 (Rev. 1) are supported by relevant Safety Guides (cf. submodule 2.4.1), which contain recommendations on how to comply with safety requirements.
The Specific Safety Guide developing recommendations relevant to accident management is SSG-54, Accident Management programmes for Nuclear Power Plants (2019), while other Safety Guides relevant to the scope of the SAMG-D Toolkit are recalled in the list of Publications.
