Abstract Personality traits have been recognized as an important means to mitigate psychological and physiological effects on human performance. In the nuclear industry, personality traits have been utilized only to screen out potential employees of mental illnesses. Although cognitive characteristics are considered in second generation HRA methods, there is no or superficial consideration about personality itself. Thus, an experiment was conducted to examine the relationship between personality traits and diagnosis performance in unexpected plant conditions of NPPs. As a result, five personality facets correlated with diagnosis performance were identified. The empirical data were used to derive an equation for diagnosis performance and a multiplier of personality factor through a regression analysis. This study proved that personality traits can be utilized in human resource management to maximize operators’ performance, and the results can be utilized as a useful empirical source for HRA experts to judge effects of personality traits on human performance.

核电厂意外工况下操作人员性格对诊断性能影响的实证研究

摘要 人格特质已被公认为减轻对人类表现的心理和生理影响的重要手段。在核工业中，个性特征仅用于筛选潜在的精神疾病员工。虽然在第二代 HRA 方法中考虑了认知特征，但对人格本身没有或肤浅的考虑。因此，进行了一项实验，以检查在核电厂意外植物条件下人格特征与诊断性能之间的关系。结果，确定了与诊断性能相关的五个人格方面。经验数据用于通过回归分析推导出诊断性能方程和人格因素乘数。
