Abstract The wall thinning management program at Hamaoka Nuclear Power Station stipulate object points and test frequencies dependi ng on wall thinning environment (flow condition, material). Currently, object points and test frequency are determined conservative ly, which contribute to an increase of radiation exposure of filed workers. Development of measurement technology and improvement of prediction technology for a progress of wall thinning may enable utilities to conduct a more effective wall thinn...

Expectations of Wall Thinning Management For Development of Measurement Technology and Improvement of Prediction Technology for Progress of Wall Thinning

The new regulatory requirements for inspections at nuclear power station took effect in January 2009,which requi re utilities to enhance an optimization of maintenance programs. At the same time, this regulatory change made it possible for utilities to apply for an extension of the operating cycle of a plant from 13 months of previous regu latory limit up to 24 months.In this paper, approaches to extend operating cycle of Hamaoka Unit 3 are described....
