Cultural Profiles of Non-MCR Operators Working in Domestic NPPs

Traditionally, the safety of NPPs has been evaluated by the PSA (Probabilistic Safety Assessment) or PRA (Probabilistic Risk Assessment) technique that quantifies the integrated safety of a whole system. In this regard, HRA (Human Reliability Analysis) plays an important role because it should quantify the possibility of HFEs (Human Failure Events) affecting the safety of NPPs. Therefore, the provision of sufficient data that are helpful for understanding the nature of HFEs under a given accident sequence is indispensable for estimating more realistic HRA results. To address this issue, one of the technical obstacles is the cultural effect on the performance of human operators. That is, it is suspicious for an HRA practitioner to use HRA data collected from another country or organization without sufficient understanding the nature of cultural differences. In this study, as one of the practical approaches to unravel this question, the cultural profiles of non-MCR operators are investigated in detail with respect to their operational experience.
