Description (excerpt):
The Nuclear Energy Agency (NEA) Working Group on External Events (WGEV) was established by the Committee on the Safety of Nuclear Installations (CSNI) in June 2014 with the aim of improving the understanding and treatment of external hazards in order to support the continued safety performance of nuclear installations and improve the effectiveness of regulatory practices in NEA member countries. Based on its work with respect to different natural hazards, such as coastal flooding, riverine flooding and high winds, the WGEV identified a common challenge: uncertainties related to hazard assessments. Therefore, a two-phased task on “uncertainties in the assessment of natural hazards (excluding earthquakes)” was proposed to, and accepted by, the CSNI. Phase 1 of this task is intended to provide an overview of the types of uncertainties that need to be considered depending on the type of natural hazard, the data sources and the assessment approaches.
