概要

Severe accident (SA) like core meltdown had not been considered to occur in Japan because we believed to have taken perfect measures for 1st~3rd layers of the defense in depth(DiD). The direct cause of Fukushima accident was loss of all AC power by an unexpected huge tsunami, but the fundamental cause was insufficient measures for the 4th&5th layers of DiD. From this point of view, European plant in vestigations have been performed to grasp how they are taking SA measures. Before Fukushima-Daiichi accident, SA measures of our country were far behind from the foreign countries, but nowadays they ha ve caught up and have reached as almost same level as foreign countries in accordance with NRA’s new regulation. However, we will plan further safety improvement based on foreign plants investigations.
