Probabilistic safety goals: Phase 3 — status report

Jan-Erik Holmberg, Michael Knochenhauer

Research output: Book/ReportReport


The first phase of the project (2006) described the status, concepts and history of probabilistic safety goals for nuclear power plants. The second and third phases (2007–2008) have provided guidance related to the resolution of some of the problems identified, and resulted in a common understanding regarding the definition of safety goals. The aim of phase 3 (2009) was to increase the scope and level of detail of the project, and to start preparations of a guidance document. Based on the conclusions from the previous project phases, the following issues have been covered: - Extension of international overview. Analysis of results from the questionnaire performed within the ongoing OECD/NEA WGRISK activity on probabilistic safety criteria, including participation in the preparation of the working report for OECD/NEA/WGRISK. - Use of subsidiary criteria and relations between these. - Numerical criteria when using probabilistic analyses in support of deterministic safety analysis. - Guidance for the formulation, application and interpretation of probabilistic safety criteria
