Support measures for Information display and accident response for emergency response systems in severe accidents

Various measures have been taken to prevent the development of severe accidents and to ensure safety even in the event of major accidents from the improvement of national regulatory systems and emergency response organizations, to the reinforcement of emergency response equipments in the nuclear power plant against natural disasters. Supporting decision-making and response measures of accident response personnel, including operators, is one of these measures. This study analyzed the current state of emergency response systems against nuclear accidents and the vulnerabilities of severe accident response systems. Based on this, we have developed measures to support information display and countermeasures for efficient coping of accident response personnel. In this study, we analyzed emergency response systems at domestic and abroad, and applied the keywords obtained from the existing vulnerability analysis report to find the parts that need to be supplemented. Based on this, we developed measures to support accident information display and accident response. The eight measures developed by this study can be used as important considerations in the process of continually strengthening and improving the emergency response system in case of major accidents due to extreme disasters in the future.
