INTERNATIONAL ATOMIC ENERGY AGENCY, Development and Application of Level 2 Probabilistic Safety Assessment for Nuclear Power Plants, IAEA Safety Standards Series No. SSG-4 (Rev. 1), IAEA, Vienna (2025), https://doi.org/10.61092/iaea.buld-d6ia
Probabilistic safety assessments (PSAs) are recognized as an important tool for assessing the level of safety for nuclear power plants. In particular, the Level 2 probabilistic safety assessment for nuclear power plants provides key insights about the potential radioactive releases that could affect the workers, the public and the environment following a severe accident. The purpose of this Specific Safety Guide is to provide an updated international accepted methodology for the development of a high quality Level 2 probabilistic safety assessment for nuclear power plants. The revised Specific Safety Guide is intended for use by designers, operating organizations, technical support organizations and regulatory bodies in the development, application and independent review of Level 2 PSA. The revised Safety Guide is also intended for use in connection with both the review for authorization (licensing) of the construction and the operation of new nuclear power plants (NPPs) and the safety re-evaluation of existing NPPs during periodic safety reviews and modifications.
