초록

The two papers in series deal with development of a new human reliability analysis (HRA) method, SAM-L2HRA, for evaluating severe accident management (SAM) strategies utilizing portable equipment for preventing and mitigating severe accidents. The first paper, Part I, introduces technical background for developing SAM-L2HRA, including identification of task characteristics of severe accident management guidelines (SAMGs) and the critical steps of individual SAM strategies with their likelihood of human errors and decision-making associated with each strategy to be included in the SAM-L2HRA framework. Based on the identified task characteristics and context of SAMGs, an approach to Level 2 HRA based on the technical support center (TSC) SAMGs, SAM-L2HRA, is outlined. To have more elaborate basis for SAM-L2HRA, the Table-Top eXercise (TTX) experiments have been designed and conducted under postulated severe accident scenarios, and the results and insights gained from the experiments and interviews with the subjects were summarized.
