PROBABILISTIC SAFETY ANALYSIS

  • increasingly used in many countries, in a complementary manner to the traditional deterministic design basis analyses and defense-in-depth considerations
  • part of the decision-making process in assessing the level of safety of nuclear power plants and supporting various risk-informed applications
  • performed in order to assess the risk of fuel damage and radioactive releases from a range of internal initiators and external hazards
  • regulatory bodies in many countries require PSA to be performed for licensing purposes
  • used to support plant design and operation through the applications such as:
      • plant risk profile and identification of design improvements
      • risk informed optimization of technical specifications
      • risk informed in-service inspection programs
      • configuration risk assessments to support implementation of plant maintenance programs
      • risk informed categorization of systems, structures and components to support quality assurance requirements
      • management of safety during shutdown and other modes of operation
      • support to the development of severe accident management guidelines
