Using the Significance Determination Process of the US Reactor Oversight Process, we will clarify the significance level of the expected inspection findings in Decommissioning Reactors and the factors that increase the significance level. We will also summarize the differences in the inspection program for Decommissioning Reactors in Japan and the USA. Then, based on the characteristics of safety significance/ risk and the comparison of inspection program in Japan and the USA, we make grounded recommendatio...

The Japan Atomic Power Company(JAPC) has been applied safety measures to Tokai-2, Tsuruga-1 and Tsuruga-2 in the past. JAPC will continuously apply effective and reliable safety measures against severe accident, to evaluate lessons based on many information and lesson from not only Fukushima Daiichi Nuclear Power Plant accident but also Tokai-2 experience. In this paper, safety measures which have been applied and will be applied are described. ...

Cracks were found at shroud support of Tokai II Power Station in 24th outage. Flaw evaluation of these cracks was performed applying Co des for Nuclear Power Generation Facilities - Rules on Fitness-for-Service ? (FFS Code) of Japan Society of Mechanical Engineers (JSME) and Guideline for Inspection and Evaluation of Reactor Internals of Japan Nuclear Technology Institute (JANTI). Evaluation methods and r esults are outlined in this report. Issues to be studied for better improvement of JSME FFS Code and J...
