Reduction of human errors in nuclear power plants

Since TMI and Chernobyl accidents, measures for minimizing the human error in nuclear power plant operations have been critically required. Many efforts such as researches of man-machine interface, improvements of safety system using the passive operation concept and enhancements of operator quality, have been conducted. In this presentation, accidents and system failures due to human errors will be introduced based on the data in Korean nuclear plants. Efforts to reduce human errors in major nuclear countries will be introduced. Finally, several measures for minimizing the human error will be suggested. (J.P.N.)
