The design targets of main control boards of nuclear power plants are as follows. (1) To make a good working environment where operators can operate plants easily. (2) To reduce the work load and operators human error. To this end, Mitsubishi group and Japanese PWR utilities have been improving main control boards design for next PWR plants with full digital instrumentation and control system. The main control boards consist of a soft operation console and a large display panel. According to our evaluation, the work load and human error rate of the new main control boards are reduced much compared with the latest plants.
In this study, in order to establish the standard specification of the advanced main control boards, validation test of mock-up for the actual plant, from 1998 to 2001, the dynamic operator verification linked with a simulator had been executed, as well as operational know-how is being collected, and detailed standardization is executed.
