This study analyzes the psychological capabilities related to job performance, such as risk perception, job satisfaction, job stress, and organizational commitment among 610 firefighters (65 own firefighters, 184 initial firefighters, and 361 local firefighters) working at various nuclear power plants. The interrelationship between the perception of risk and changes in the psychological capabilities of fire officials under the jurisdiction of nuclear power plants was investigated. The data were collected through a survey. We used SPSS 23.0 to perform descriptive statistics, correlation, one-way ANOVA, and multiple regression analysis of study variables, and AMOS 23.0 to validate the structural equation modeling (SEM) analysis. The study results show that psychological capabilities related to job performance differed significantly for each organization to which the firefighters belonged, followed by job satisfaction, job stress, and risk perception as variables that affect organizational commitment. The high expectations of the transition to national positions have a positive impact on job satisfaction, which in turn increases organizational commitment. Based on the results, we discussed the necessary policy implications in terms of management to enhance the future performance of organizations.
