1.はじめに保全は、機械、電気、制御などの機器から成る、いわゆる「機械系」とそれを保全する「人間系」から構成されている。これまでの保全はこの2つの要素が渾然一体となって取り扱われ、両者を明確に分離して分析評価する手法が十分には取られて来なかった。これには社会的状況や規制などの影響もあったと考えられるが、いずれにしても保全の体系化や保全学の構築など、学術的アプローチを積極的に進めようとする気運が希薄であった。しかしながら、近年、保全を学術として捉え、それを体系化することによって、合理的効率的に保全の最適解が......

Benchmarking Field Work Maintenance Maintenance Work Community Performance Work Team
Plant design and construction have an impact on safety and economic efficiency of industrial plants. In a same manner, maintenance or field work has also big potential impact on them. However it has not drawn much attention so far. So performance by maintenance work team is discussed to improve safety and economic efficiency of industrial plants in this paper. ...

Imagination Maintenance Plan Maintenance Science MaintenanceImplementation Capability Prediction Structure System
It is difficult to predict an initiation and growth of ageing/degradation like SCC in plant comp onents, subsequent component failures, function losses or a behavior of gigantic, complex plant system like a nuclear power plant. But if it is possible to predict them, it could drastically improve the safety and economic efficiency of such plant systems. This study considered a struc ture and system of maintenance since that could improve a predictive performance of maintenance related science and engineerin...

CFD Cylindrical Tank Froude Number Inundation Depth Tsunami Wave Force
Asakura's method is well known as the evaluation method of tsunami wave force. In this method, tsunami wave force is evaluated on the assumption that the inundation depth increases by 3 times in front of a structure. On the other hands, inundation depth is not constant around a cylindrical tank. Therefore, there is the possibility that the tsunami wave force of a cylindrical tank is overestimated by Asakura's method. In this paper, Sano's method is introduced as the evaluation method of tsunami wave force a...

In this study, a relationship between nuclear safety and inspection/monitoring was discussed. As a result of consideration, the followings were made clear. (1) Nuclear safety is secured by the combination of safety funct ns of nuclear plant system and plant managements by the human system including plant operator’s organization. (2) Nuclear plant systems should be managed for each safety system because safety functions are fulfilled for each safety system. (3) The integrity of concerned system in the futur...
