The Nuclear power plant (NPP) industries in Korea have been making efforts to reduce the human errors which largely contributed to 120 nuclear reactor trips from the year of 2001 to 2006. This study aims to develop a Crew Resource Management (CRM) training program that helps to improve plant performance by reducing the number of the reactor trips caused by the operators' errors.The CRM program was developed with focusing on non-technical skills, such as leadership, situation awareness, teamwork, and communication, which have been widely known to be critical for improving the operational performance. In this study, the CRM program was applied to the operators performing simulation scenarios in the mockup of the main control room of the APR-1400. The CRM program was proceeded with the lectures, emergency operation procedure scenarios designed by the process expert, task monitoring, and debriefings. Finally we verified the effectiveness of CRM training through the attitudes test and BARS(Behaviorally Anchored Rating Scale) to measure learning that has resulted from participation in the training program. The implication of the evaluation results was discussed in detail.

An increased use of teams of actors within complex systems has led to the emergence of various approaches for the assessment of different features associated with team performance. Over the last two decades, the performance of teams in complex systems has received considerable attention from the human factors community, and a number of methods have been developed in order to assess and evaluate team performance. The purpose of this paper is to propose a methodology for measuring team efficiency of operators in the advanced main control room of Korean nuclear power plant. Team efficiency is an index which is estimated of gabs between individual performances and team performance. The index was developed to compare among teams through past all performance measurements.
