After the Fukushima-daiichi accident, the KANSI Electric Power has implemented various safety measures against severe accident for nuclear power plants. In this paper, we will explain about overview of measures and internal flooding caused by the high energy line break. The high energy line break may cause common mode failure which damages the multiplexed and diversified protection system at the same time by a single piping break. Therefore we have to take all possible measures for the prevention from int...

Safety measures for severe accident on the KANSAI nuclear power plants

The Kansai Electric Power Company has been carrying out continuously activity for the improvement in safety of nuclear power plants after the TEPCO Fukushima Daiichi NPP accident. We thought that the main causes of having resulted in the severe accident were based on the long time SBO and the LUHS accompanying flood, and installed the alternate mobile power source and the alternative injection pumps while implementing the measure against waterproofing as the first safety measures. Now, we are also im...
