The development of K-HPES: a Korean-version human performance enhancement system [for nuclear power plant control]

K-HPES is a Korean-version HPES (human performance enhancement system) developed on the basis of INPO-HPES in 1993. The development of K-HPES was an effort of KEPRI (Korea Electric Power Research Institute) to reduce human errors and to enhance human performance in nuclear power plants (NPPs), and the program is currently being operated at all NPPs in Korea. KEPRI is now developing a computerized support system, tentatively named CASHPES (computer-aided system for HPES), which facilitates the K-HPES analyzer in performing K-HPES analysis tasks. This paper describes the K-HPES program and the current status of CASHPES development.
