Japan Atomic Power Company, the Tsuruga power plant’s operators, denies what the Nuclear Regulation Authority calls “seismic hazards” as an active fault line lies beneath reactor no. 2. The NRA told the power plant operators to evaluate possible risks should an earthquake occur. But the Japan Atomic Power Company claimed that there is no chance for a meltdown, even without the pool of cooling water. It also released an official report on July 31 to prove its safety claims on the power plant.
Compared to what led to Fukushima meltdown, the Tsuruga nuclear power plant is confident that no meltdown will happen even without the pool to keep the reactors’ temperature stable. According to the Japan Atomic Power Company, ventilation systems between the fuel assemblies will allow air to pass through and serve as a cooling agent. The metal pipes serving as fuel cover may increase its temperature until 420 degrees, but the plant operator said that there is no need for new safety measures.
Although the Japan Atomic Power Company described the scenario involving the cooling water, none was presented as measures if the reactors are shaken because of an earthquake, although a group of geology, seismology and nuclear experts were commissioned to further review the NRA’s claims. The group believes that NRA’s fault findings may need further research as no active fault line was found by the group. Still, should the report submitted by Tsuruga operators give the NRA no satisfaction, it is most likely that Tsuruga will not resume operations soon.
