A nuclear power station is designed to be safe based on the concept of stopping the fission chain reaction, cooling the fuel and confining radioactive materials in case of an emergency. However, the accident at TEPCO's Fukushima Daiichi Nuclear Power Station caused by a tsunami following the massive magnitude 9.0 earthquake on March 11, 2011 deprived the station of its cooling and confining functions, which led to a severe accident.

The New Regulatory Requirements that were introduced after the accident incorporate enhanced design to prevent similar severe accidents from happening again, as well as countermeasures against earthquakes and tsunami, based on the lessons learned from the accident. The Requirements also cover a wide range of natural phenomena, including volcanic activity, tornados, forest fires as well as earthquakes and tsunami, considering the natural disasters that often occur in Japan.

The Kansai Electric Power Co. is fully committed to promoting voluntary safety initiatives while strictly adhering to the New Regulatory Requirements.
