Outcomes of an International Initiative for Harmonization of Low Power and Shut-down Probabilistic Safety Assessment

Many Probabilistic Safety Assessment (PSA) studies completed to the date demonstrated that the risk dealing with low power and shutdown (LPSD) operation of Nuclear Power Plants (NPPs) often is comparable with the risk for at-power operation, and the main contributors to the LPSD risk are often dealing with human factors. Since the beginning of the nuclear power generation, human performance has been a very important factor in all phases of the plant lifecycle: design, commissioning, operation, maintenance, surveillance, modification, decommissioning and dismantling. This aspect has been confirmed by recent operating experience. This paper provides the insights and conclusions of a workshop organized in 2007 by the IAEA and the Joint Research Centre of the European Commission, on Harmonization of Low power and Shutdown PSA for WWER NPPs. The major objective of the workshop was to provide a comparison of the approaches and results of human reliability analyses (HRA) and gain insights for an enhanced handling of human factors.
