Probabilistic safety assessment (PSA) of nuclear power plants (NPPs) complementsnthe traditional deterministic analysis and is widely recognized as a comprehensive, structurednapproach to identifying accident scenarios and deriving numerical estimates of risks dealingnwith NPP operation and associated plant vulnerabilities. Increasingly, during the last years,nPSA has been broadly applied to support numerous applications and risk-informed decisionsnon various operational and regulatory matters. The expanded use of PSA in the risk-informedndecision making process requires that PSA possess certain features to ensure its technicalnconsistency and quality.nThis publication is aimed to further promote the use and application of PSAntechniques in Member States. The publication provides a comprehensive list of PSAnapplications and describes what technical features (termed ‘attributes’) of a PSA should bensatisfied to reliably support the PSA applications of interest. A consideration has been alsongiven to the basic set of attributes characterizing a ‘base case PSA’ that is performed with thenpurpose of assessing the overall plant safety.nThis publication can support PSA practitioners in appropriate planning of a PSAnproject taking into account possible uses of the PSA in the future. The publication can be alsonused by reviewers as an aid in assessing the quality of PSAs and judging the adequacy of anPSA for particular applications. In addition, it is also foreseen to use the publication tonsupport the independent peer reviews conducted by the IAEA in the framework of thenInternational Probabilistic Safety Assessment Review Team (IPSART) safety service.
