The Nuclear Regulation Authority set new guidelines Wednesday for fallout disaster mitigation measures, expanding the distance where special preparations are required to 30 km from atomic power plants.
While details need to be fleshed out, such as specific criteria for evacuation, the guidelines were revised to meet international standards and rewritten in plain language to be more easily understood, the NRA said. The NRA's predecessor was harshly criticized over its handling of the Fukushima crisis.
Based on the guidelines and other information provided by the NRA, local governments hosting nuclear plants and those on the periphery are expected to craft their own disaster mitigation plans and set the scope of the emergency zones by March.
