According to Lianfake News, abnormal conditions have occurred at the Fukushima Daiichi nuclear power plant in Japan.
Tokyo Electric Power Company believes that it may be the impact of the earthquake off the coast of Fukushima on the evening of the 13th of this month.
According to a report by the Japan Broadcasting Association (NHK) on the 22nd, the nuclear reactor safety shell of Unit 1 of the Fukushima Daiichi Nuclear Power Plant of Tokyo Electric Power Company, which is carrying out the scrapping of nuclear reactor, has a pressure drop phenomenon.
In order to reduce the risk of hydrogen explosion, staff often inject nitrogen into the safety shell to raise the pressure.
At about 18: 00 local time on the 21st, the company found that the pressure in the safety shell of Unit 1 had been reduced from 1.2 kPa to 0.9 kPa.
After the offshore earthquake of Fukushima on the 13th, the water level in the safety shell of Unit 1 dropped.
Tokyo Electric Power Company believes that the damage may have been partially affected in the nuclear leakage accident caused by the March 11th earthquake.
