Some Insights from HRA Related to Low Power and Shutdown Scenarios
In this contribution, some insights are given from detailed analysis of human factor contribution to the risk of low power and shutdown operation of WWER-440 Dukovany plant located in Czech Republic. This analysis was performed as a part of several contracts closed between Nuclear Research Institute Rez and NPP Dukovany in past years. The main focus of the effort was complete human reliability analysis addressing all points necessary for development and applications of LPS PSA model. Rather than giving complete description and results of the analysis performed, the intention of the contribution is to bring more general conclusions, which may be helpful for new developers of shutdown HRA.
