The purpose of human reliability analysis (HRA) is to provide a quantitative conclusion for Probabilistic Safety Assessment (PSA) and detect the weak points of a system. The failure probability of post-accident human factor events is composed of cognitive failure probability PI, non-response probability P2 and the failure probability P3 of conducting the critical actions according to EOPs. The paper adopts the method of combining THERP and HCR and quantifies P1, P2 and P3 separately. In the analysis procedure the particular time division and para...
