An NHK survey revealed that 70% of Japan’s prefectural governments can not hold nuclear disaster drills, because there are no national nuclear standards.
13 prefectures were surveyed. They’ve held nuclear disaster drills before. The problem is that the ongoing nuclear disaster at Fukushima Daiichi has literally erased previous guidelines concerning nuclear disasters.
Most of the prefectures are waiting for the national government to come up with new standards. However, four prefectures says they will come up with their own temporary guidelines, and hold their nuclear disaster drills anyway.
