Description
In Japan, Tsuruga unit n.2, Ohi unit n.3/4, and Genkai unit n.3/4 power stations adopted the prestressed concrete containment vessel (PCCV). Since the PCCV was introduced from the U.S., the in-service inspection test (ISI) to confirm the structural integrity was basically put into practice in conformity to the U.S. NRC Regulatory Guide 1.35. Experimental and analytical examinations are enforced at ISI to improve the reliability of the evaluation method on structural integrity which is the same as when the series of planning, drafting, enforcement tests to confirm structural reliability were performed when PCCV was introduced. As a result, the present evaluation method on structural integrity was confirmed to be quite reliable. In this paper, the ISI practice in Japan is introduced (practice on strain measurement, evaluation method on residual tendon forces) together with some results of the series of experimental studies enforced to improve the reliability of the evaluation method
