WGRISK and PSA: Past, Present, and Future

摘要

The current work program of WGRISK, the Nuclear Energy Agency (NEA)/Committee forthe Safety of Nuclear Installations' (CSNI) Working Group on Risk Assessment, involves a broadrange of topics. WGRISK task groups are addressing human reliability analysis data needs,probabilistic safety assessment (PSA) methods for non-seismic external events, probabilistic riskcriteria, methods for analyzing digital instrumentation and control systems, and low power andshutdown PSA. Most of these tasks are expected to be completed in 2008. To support theidentification and management of future activities, the working group, along with other CSNI workinggroups, has updated its integrated plan. The updated plan directly addresses future challenges andassociated issues identified by the CSNI, thereby ensuring that the WGRISK program appropriatelyaddresses user needs.
