Comparison of Unsafe Acts Identified from Simulator Training Record Analysis under ISLOCA and MLSB+SGTR Scenarios

In this light, one of the most established approaches is to conduct an HRA (Human Reliability Analysis). Accordingly, various kinds of HRA methods have been developed for several decades. In addition, in the case of the nuclear industry, extensive effort has been spent to collect sufficient data that are helpful for conducting HRA (i.e., HRA data) from the full-scope simulator of NPPs. For this reason, we published a standardized guideline to specify how to gather HRA data from simulator training records and crated IGT (Information Gathering Template) specifying what kinds of measures should be observed during the simulations. We also defined inappropriate human behavior (or UA; Unsafe Act) for HRA data collection and showed case study to identify USs with simulator training record. The purpose of this paper is to compare UAs identified from human performance analysis with simulator training record under an ISLOCA (Interfacing System Loss of Coolant Accident) and a SGTR (Steam Generator Tube Rupture) immediately following an MSLB (Main Steam Line Break) scenarios for a Westinghouse 3-loop plant.
