For the safety operation and cold shutdown of nuclear power plant, the I&C equipment is important to grasp the state of nuclear power plant. On March 11, 2011, at the Fukushima Daiichi nuclear accident that progressed to severe accident with core damage, many of the I&C equipment lost their functions and it was difficult to grasp the state of nuclear power plant. It is very important of measuring and grasping the parameters of nuclear power plant (e.g., RPV water level, RPV pressure) for accident management, at severe accident such as the Fukushima Daiichi nuclear accident.
In this paper, we introduce the actions for the I&C equipment for severe accident management in Kashiwazaki-Kariwa nuclear power plant units 6 and 7 (KK-6/7), based on the lessons learned from the accident.
