I.リスクコミュニケーションとはなにか(1)リスクとはなにか リスクコミュニケーションの話をするには、その前提となるリスクについて、まず共通 の認識を持つ必要がある。ところが残念なことに、リスクには学問分野によってさまざま な定義の違い、つまり学問的「方言」がある。そのことを知っておかないと、同じリスク ということばを使いながら、実際は同床異夢であることが多い。このことは、特に一般住 民やマスコミに対してリスクを述べるときに留意しておく必要がある。 (1) リスクの常識概念一般の住民がイメージするリスクは......

This study proposes an innovative system based on risk evaluation and management for plant engineering and maintenance. This system was carried to completion by in troducing “Equipment Function“ to the conventional risk evaluation indexes comprised of “Process Property and “Equipment Property”. This new system is thought to b e very useful not only for plant operation to assure better performance and reliability together with realizing minimization of maintenance cost, but also to make g ood understanding ...

Today, many troubles such as big accidents, human errors, active concealment, etc. are occurring frequently, and have had a bad influence on the reliability and security of a human life. As a cause of these problems, lack of information and knowledge, lack of tactics to safety ensuring, lack of the strategy to safety, etc. are pointed out. To solve these problems as mentioned, the technology concerning risk management immediatel y needs to be systematized. As such a technical system, we have proposed the c...

Management and maintenance tools are now greatly available for contributing reduction of maintenance cost and time. These tools surely give us much benefit, but are only for maintaining reliabilities of the equipment. Reliability of the plant dep ends on the design and actual operating conditions. Accordingly, the matter to do first is to consider facilities in the range of the plant life cycle. This brings the result that “process property” and “equipment property” are required besides “ equipment functio...

The feasibility study of RI-ISI (Risk-Informed In-Service Inspection) has been carried out based on 2-loop PWR as the pilot pl ant. The knowledge about failure potential derived from “Whole Maintenance Program for Piping” and results of PSA were combined in this work. The risk matrix of EPRI was referred to when the importance of piping segments was classified. It turns out that RI-ISI could reduce the number of welds required for inspection by present way, while the risk level remains at the same level....

We verified about the availability of the RCM method used successfully in the U.S., and the possibility of application to the Hamaoka nuclear power st ation. In Japan, the introduction of RCM method to domestic power plants has been examined, but the method has been too special for public to obtain t he acknowledgment and consensus. In this paper, we discussed our unique approach classifying the equipments from viewpoints of safety, operation and s ocial effect etc. The importance classification was done f...

Toshiba has developed laser-based maintenance, inspection and repair technologies as countermeasures against stress corrosion cracking (SCC) in nuclear power reactors. Laser peening (LP) is a novel process for preventive maintenance, which improves residual stress from tensile to compressive on material surface by irradiation laser pulses in water. Laser-ultrasonic testing (LUT) is capable of detecting and sizing SCC having a depth of about 0.5 mm. Underwater laser welding can be fulfilled by making local ...

In multiaxial low cycle fatigue, the directional distribution of initiated cracks affects the subsequent growth of a dominant crack. So, it is important to clarify the characteristics of crack initiation to improve the life evaluation in multiaxial fatigue. In this work, a simulation pr ocedure of fatigue crack initiation under multiaxial stresses was first established based on the modeling of crack initiation in slip-band systems assumed in polycrystalline metals. Especially, the directional distribution ...
