The threats to nuclear power plants are not restricted to earthquakes and tsunamis. The United States’ Nuclear Regulatory Commission compiled anti-terrorism measures in the wake of the 9/11 terrorist attacks. Japan similarly compiled new safety standards that went into effect in 2013. The new standards in Japan envisage such threats as an airliner crashing into a nuclear reactor building. They require plants to have an emergency control room at least 100 meters away from the nuclear reactor building, along with cooling pumps, so that the operator can continue to cool the nuclear reactor even if the adjacent control room is damaged. The first reactor to be restarted after the Fukushima nuclear disaster was the No. 1 reactor at the Sendai plant, and now it has reached that five-year deadline. Yet in spite of being granted a five-year period of grace, it failed to meet the requirements. It can’t be helped if the operator is seen as having made light of safety. So far nine nuclear reactors operated by the Kansai, Shikoku and Kyushu power companies have been restarted — and all of them are facing delays in the construction of response facilities. Kansai Electric Power Co. is due to halt the No. 3 and No. 4 reactors at its Takahama nuclear power plant this year.
