DEVELOPMENT OF PERSONAL-COMPUTER AIDED AN ALYSIS AND EVALUATION SUPPORT SYSTEM FOR HUMAN RELATED INCIDENTS IN NUCLEAR-POWER-PLANTS

A remedy-oriented analysis and evaluation procedure, had been already developed by the authors, as a method of making systematical survey of fact-finding cause identification, and proposal of countermeasures fo r human-related incidents in nuclear power plants. This paper describe s a personal-computer based analysis and evaluation support system whi ch was newly developed for the purpose of practical and extensive use of the, above procedure. The computer-based system can support the ana lyst's desk top analysis and evaluation procedure by replacing each st ep of the procedure into some prescribed questions so as to improve th e following points:(1) to make analysis more systematically;(2) to pro vide analysis reports automatically;(3) to make it easy to master the procedure, etc. As a consequence of the support system introduction, i t was shown that the system could reduce the time required for analysi s and evaluation by a half, and also possible to reduce the time neces sary for the training course for the user to have better understanding s of the procedure, than without the system.
