Tokyo, Feb. 8 (Jiji Press)—Measures against flooding are insufficient at 10 nuclear power facilities in Japan, mainly at connecting sections, investigations by their operators have revealed.

The investigation results were reported at Wednesday’s regular meeting of the Nuclear Regulation Authority.

Among the 10 are Tokyo Electric Power Company Holdings Inc.’s Kashiwazaki-Kariwa nuclear power station in Niigata Prefecture, its Fukushima Daini nuclear plant in Fukushima Prefecture, and the Japan Atomic Energy Agency’s Monju prototype fast-breeder reactor in Fukui Prefecture.

The NRA instructed power companies last November to carry out the probes for reactor buildings and other important equipment, after some 6.5 tons of rainwater entered the number 2 reactor building at Hokuriku Electric Power Co.’s Shika nuclear plant in September 2016.

At the Shika plant, a power panel for lighting equipment shorted out due to the rainwater inflows. The section connecting the number 2 reactor building and an underground trench for power cables and other equipment was later found to have not been waterproof.
