概要
The Fukushima Daiichi nuclear disaster was initiated by the Tohoku earthquake and subsequent massive tsunami on 11 March 2011. To prevent the event as the Fukushima Daiichi nuclear disaster, we had implemented the necessary safety reinforcement measures in Shika Nuclear Power Stations. In this paper, we are going to introduce the flood prevention measures that prevent seawater from entering the power stations. And we also secured emergency power supplies for the case of loss of all AC power supplies. In addition, we secured the function of coolant systems by diversifying water sources and deployment of fire engines and so forth. As the next step, including the adaptation of Shika Nuclear Power Stations for the new regulations that are going to be forced on next July, not staying the existing state, we are going to study and implement the further measures to improve safety and reliability of Shika Nuclear Power Stations.
