Fukushima nuclear power plant facilities in Japan are abnormal, suspected to be caused by the 13th earthquake
China News Service, Tokyo, February 22. According to a report by the Japan Broadcasting Association (NHK) on the 22nd, Japan’s Tokyo Electric Power Company’s Fukushima Daiichi Nuclear Power Plant Unit 1 nuclear reactor containment, which is undergoing nuclear reactor scrapping, has experienced a pressure drop. Tokyo Electric Power Company believes that it may be the impact of the Fukushima offshore earthquake on the evening of the 13th of this month.
p >In order to reduce the risk of hydrogen explosion, the staff often input nitrogen into the containment to increase the pressure. At 18:00 local time on the 21st, the company found that the pressure in the containment of Unit 1 had dropped from 1.2 kPa to 0.9 kPa.
After the Fukushima offshore earthquake occurred on the 13th, Unit 1 experienced a drop in the water level in the containment vessel. Tokyo Electric Power Company believes that it may be that the damaged part of the nuclear accident caused by the “March 11” earthquake was exposed to the water surface due to the drop in the water level, and the gas leak caused the pressure to drop. It is reported that the water injection into the containment is still continuing, and no radioactive material has been leaked.
At present, Tokyo Electric Power Company is continuously monitoring it, and the relevant data of multiple monitoring points in the station shows no abnormalities. Tokyo Electric Power Company stated that as long as the reactor containment is continuously filled with water, there will be no safety issues. (End)
