This paper presents the results of a preliminary assessment of human factors concerns associated with the six reactor control rooms at the Kozloduy Nuclear Power Plant in Bulgaria. This initiative was sponsored by the Committee of Energy, Bulgaria, as part of a multi-faceted project that examined emergency operating procedures, training, and risk-based maintenance practices at Kozloduy. The goal of the study was to determine the overall adequacy of the interfaces, from a human error prevention perspective, between operator and plant processes as found in the control rooms, and if warranted, to develop a program plan for conducting subsequent detailed control room design reviews. The need for this study was stimulated in part by a report prepared by the International Atomic Energy Agency which found that WWER-440 model 230 reactor control rooms were in urgent need of human factors attention. This paper summarizes the findings from the human factors portion of the study, and discusses potential concerns associated with applying U.S. developed human factors engineering criteria to an eastern European nuclear power plant.
