Abstract
The overall objective of the OECD Nuclear Energy Agency (NEA) CSNI (Committee on the Safety of Nuclear Installations) Working Group on Risk Assessment (WGRISK) is to permanently enhance the understanding of Probabilistic Risk Assessment (PRA, synonymously used for PSA) and facilitate the use and application of probabilistic approaches as an important tool for nuclear safety assessment. WGRISK therefore carries out activities to exchange risk related information between PRA experts in member countries and to advance the use of this tool for improving safety. The following WGRISK activities are currently ongoing: The task “Human Reliability Analysis in External Events PSA – Survey of Methods and Practice” close to completion, the task “Status of Site Level PSA (including Multi-unit PSA) Developments” ongoing in its second phase, the joint task of WGRISK and the NEA Database Projects on the “Use of OECD/NEA Database Project Operating Experience Data for Probabilistic Safety Assessment”, where a common Workshop took place in spring 2018, and the task “Development and Comparison of Digital I&C Modelling Approaches for PSA (DIGMAP)”started most recently in 2017. Three further tasks are close to completion, the report on “Use and Development of PSA in Member and Non-member Countries” being updated nearly every five years and updates of two WGRISK Technical Opinion Papers (TOPs) on Fire PSA and Seismic PSA highlighting the actual status of PSA for these two types of hazards.
