The pipe-wall thinning can be one of the most important problems in safety as well as maintenance. After the Mihama accident, JSME established a performance-based rule and technical rules for thermal power plants, PWRs, and BWRs for the management. Various organizations began the research regarding the pipe-wall thinning. Pipe-wall thinning is complex phenomena which relate to the fluid dynamics, the water chemistry, and material sciences. The management can be an integrated technology that consists of screening of management locations, the evaluation of thinning rate, the method of the wall thickness measurement, the evaluation of remaining period for fit for service, and the repair method, etc. In JSME, a R&D strategy was considered based on the needs to revise and enhance the rules. This report shows the outline of the strategy.
