Emergency declared at Fukushima No.1 nuclear plant
NHK world Japanese News web describes Tokyo Electric Power Company has reported to the Japanese government an emergency situation at a nuclear power plant in quake-stricken Fukushima Prefecture.On Sunday morning, the company said that radiation levels on the border of the compound of the Fukushima No.1 nuclear power plant had exceeded government standards. The report was made based on the country's special law on measures against nuclear disasters.
Work to vent air from the containers of the reactors at the plant was carried out on Saturday afternoon and Sunday morning. The measure was taken to release pressure in the containers after the reactors' cooling system failed. The power company says the procedure may have led to higher radiation levels and is investigating.
The company says radiation levels near the front gate of the plant gradually went down after rising to 1,015 microsieverts per hour on Saturday afternoon. But levels rose again to 882 microsieverts on Sunday morning. Radiation levels above 500 microsieverts must be reported to the government by law.
