Development and Application of Level 1 Probabilistic Safety Assessment for Nuclear Power Plants

The objective of this Safety Guide is to provide recommendations for meeting the IAEA safety requirements in performing or managing a level 1 probabilistic safety assessment (PSA) project for a nuclear power plant. These recommendations promote technical consistency among level 1 PSA studies and support applications of PSA and risk informed decision making. The Safety Guide’s scope encompasses all operational conditions of the plant and potential initiating events and hazards.
