概要 （図表や脚注は「報告書全文」に掲載しております）

原子力発電所における異なる組織・体制上の指揮・命令系統の不具合から生じる組織的エラーおよび保守作業の要求レベルと保守作業員の知識・経験レベルとの不適合(ミスマッチ)から生じる個人的エラー、強いては、重大な事故・トラブルの発生を未然に防止するため、保守作業の難易度と関係者(監理者、工事責任者、作業責任者)等の作業遂行能力との最適化を図り、保守作業現場における「作業信頼性」および「人間信頼性」の向上に資する斬新な「ナビゲーション法によるRHRポンプ保守教育支援プロトタイプシステムの概念設計」を提案した。

概要 （英文）

The purpose of this research is beforehand prevention of the systematic error produced from the fault of command / command system on the different organization in a nuclear power plant, and the individual error of the demand level of maintenance work, and knowledge and experience level of a maintenance worker produced from it being incongruent (mismatch), and generating of the serious accident and a serious trouble.This research attains optimization with the difficulty of maintenance work, and work execution capability, such as the persons concerned (a supervision person, a construction person,work person), and proposes the new "maintenance educational support technique" which is useful to the improvement in "work reliability" and "beforehand prevention of a human error" in the maintenance work spot. The main results concerning this research are shown below. (1) In this research, concept design of RHR pump maintenance work educational support prototype system was performed on the basis of the examination result of a process analysis of RHR pump maintenance work, load mapping, a rule base / knowledge base and a data base / filing system. (Figure. 1 reference ) Consequently, when an educator-ed talked with a data base / filing system along with load mapping of maintenance work (Why, How, What), a possibility that it could reach exactly from work start to the sub goal or the last goal and timely was suggested. (2) As a result of classifying "the difficulty of maintenance work", and "man's work execution capability" and comparing the result using SRK (behavior of man) index which Rasmussen proposed, among both, it turns out that difference (inharmonious) arises.(Tab.1). The exact presentation of the educational method or educational material which responded to knowledge and experience level of an educational achievement target or an educator-ed can be referred to as being connected with the improvement in work reliability, and prevention prevention of a human error as a result by then, incorporating the classification result by SRK index in the "knowledge level presumption model" and the "educational effect judging model.".
