[en] As a result, the Nuclear Safety and Security Commission (NSSC) prepared a plan for improving the safety of nuclear facilities against a major earthquake, and implemented measures to improve the earthquake response system, to strengthen the seismic capacity of NPPs and to evaluate the seismic capacity. Based on the seismology survey results, KINS plans to reevaluate the seismic design criteria of NPPs. While these activities have been carried out based on individual administrative orders of the regulatory authority in a relatively short period of time since 2011, the Nuclear Safety Act was revised to provide an additional requirement to submit the Accident Management Plan (AMP) for the Operating License. Accordingly, treatment of the above improvements related to the accident management (AM) in a comprehensive and systematic manner has become necessary when the amended laws and regulations are implemented. Therefore, in this study, we examine the status of the Post-Fukushima actions following the administrative orders of the regulatory body and self-imposed by the licensee by searching mainly the Nuclear Safety Yearbooks. Among those actions, we listed up the items that need continuous follow-up. Then we propose a desirable approach to include them in the AMP. It is very challenging to submit an AMP covering a wide range of design basis accidents, multiple accidents, external hazards, and severe accidents for all operating and new reactors after three years of the preparation period. Similarly, the work of the regulatory body that will review the plan submitted at once should be enormous. Installation of the equipment or evaluation results from the Fukushima actions should be appropriately reflected in the AMP. Among those follow-up items, we listed up those which are related to the AM and need follow-up under the AMP framework. While it is expected that preparation and review of the AMPs require much efforts, we propose a step-by-step review approach similar to that of the licensee.
