Technical Meeting on Experience in the Development and Application of Level 2 Probabilistic Safety Assessment for Nuclear Power Plants

4 – 7 May 2021
Virtual event
Vienna, Austria
Event code: EVT2003080

Objectives

The objective of the event is to provide the participants with an opportunity to contribute to the revision of Development and Application of Level 2 Probabilistic Safety Assessment for Nuclear Power Plants (IAEA Safety Standards Series No. SSG-4) by collecting experiences in the application and development of Level 2 probabilistic safety assessment in Member States.

Topics

The event will address recent experiences in Member States in specific areas related to the development and the application of Level 2 PSA for nuclear power plants, such as:

  • Assessment of the safety level improvements related to the incorporation in the NPP design of additional safety features considered for design; extension conditions; the use of non-permanent equipment; Multiunit considerations.
  • Assessment of advantages and disadvantages of strategies for dealing with core melt and with damage of fuel stored in the spent fuel pool inside of the reactor containment and their related phenomena.
  • Evaluation of considerations and factors related to modelling of human performance in Level 2 PSA.
  • Prioritization of research conducted in support of severe accident strategies and for improvements of severe accident simulation codes capabilities.
  • Enhancement and update of severe accident management guidelines using insights from Level 2 PSA.
  • Current practices considering low power and shutdown states as well as internal and external hazards, and their combinations in Level 2 PSA.
  • Development and application of Level 2 PSA for nuclear power plants with advanced reactor technologies (e.g. SMRs, non-LWR).
