There are still exist human errors in operation and maintenance tasks in all business fields. Especially human errors in maintenance tasks are significant problems. For example, mixing of extraneous material in some components, faulty wirings, faulty maintenance of screw tightening torque, etc. are still major causes of accidents with maintenance. Thes e human errors are so small incidents that the author think they are not paid sufficient attention. So, the authors recommend risk assessment of maintenance...

This paper provides the second part of the study on maintenance importance evaluation using the mathematical ‘Klee metho d'. In the second part of evaluation, a reevaluation is performed by the reference of the conventional qualitative eval uation results into the evaluation by the Klee method. As a conclusion of the whole study, additional way is considered as the better way against multiplicative way of Klee method in order to obtain better results on importance evaluation....

This paper provides the first part of the study on maintenance importance evaluation using a typical mathematical method called 'Klee met hod'. Klee method is a quantitative method and the results of the evaluation are compared with the conventional qualitative method. Actua l evaluation is performed on typical auxiliary pump parts of a nuclear power plant. As a conclusion of this study (Part 1), additional way is considered as a better way against multiplicative way of Klee method where the final conclusi...

1. 緒言原子力発電プラントには高い信頼性と安全性は勿論 のこと、設備利用率の向上と保守費削減による発電原 価の低減が強く求められている。プラント機器の保守 に関しては、従来は信頼性維持のために一定周期で点 検を実施する時間計画保全方式が採用されてきたが、 近年では保守費削減と両立するために多くのプラント で機器の運転監視に基づいて点検の要否を定める状態 監視保全方式への移行が進められている[1]。状態監視保全の運用にあたっては、 ・ 状態監視保全の適用が可能で効果的な機器の選定 ・ 監視パラメータの選定......

Abstract: This study tries to clarify the maintenance activities that can be applied risk information to, and determine priority of the application. For that purpose, first, we investigated the maintenance activities themselves, and broke them down into 75 “Maintenance Elements”. Second, we evaluated whether each “ Maintenance Element” could be applied risk information to. Third, we determined the priority of the risk application on “application merit” and “possibility” aspects. This study has revealed t...

Abstract I n an environment such as outer space where we cannot maintain the artifacts, it is the robustness that is important for artifacts. Thus the system, which has the i nformation processing circuit realizing self-maintenance function is desirable. So far some approach is tried to realize self-maintenance function using the qualitative reaso ning technique. In this study, we try to apply distributed information processing technique to this qualitative reasoning information processor, by arranging man...

In this paper, we proposed a method to estimate the configuration of wall thinning defects in pipes due to, for example, flow accelerated corrosion (FAC). The method requires measurement of circumferenti al stress distribution and internal pressure. The key issue is that the local circumferential stress and the corresponding local wall thickness are not necessary in a simple relationship, as taught in th e Strength of Material course. We first point out that not only thickness but also the length of thinne...
