Abstract: Japanese nuclear utilities just started a joint effort for maintenance optimization, in which a set of standard processes and common technical bases for maintenance program justificati on will be designed, developed and maintained. The effort is expected to contribute not only to acceleration of individual effort, but also to improvement of total plant safety and reliability....

Approach for maintenance optimization by Japanese nuclear utilities

In yoke method magnetic-particle testing, it is necessary to perform the testing at least two times by changing the direction of magnetization. In a rotating field type magnetizer using a three-phase al ternating current (AC), any directional flaw can be detected by a single testing. In this research, the distributions of the rotating magnetic flux density were evaluated by measuring this density using Hall elements (in three directions) and by numerical analysis. The distributions of the magnetic flux den...
