The blast destroyed the exterior walls of a building, but did not breach the steel housing enveloping the reactor there, officials said.

Tokyo Electric Power Co also said fuel may have been damaged by falling water levels at the Daiichi facility, one of its two nuclear power plants in Fukushima, some 240 km (150 miles) north of Tokyo. Japanese authorities battling to contain rising pressure in nuclear reactors damaged by a massive earthquake were forced to release radioactive steam from one plant on Maafter evacuating tens of thousands of residents from the area. 1 at the Fukushima Daiichi nuclear plant after an explosion that blew off the upper part of the structure is seen in this handout photo released by Tokyo Electric Power Company (TEPCO) in Fukushima Prefecture, northeastern Japan, March 12, 2011. Released steam raised radiation levels above safety limits outside the Unit 3 reactor Sunday, TEPCO officials said, adding they informed the government of an "emergency situation." Still, they said, there was no immediate threat to human health.Įdano said the radiation levels later fell. The Unit 2 reactor, though shut down by the quake, was not in the same trouble. On Sunday TEPCO released air containing radioactive materials for more than 2 hours and injected water at the Unit 3 nuclear reactor container vessel to reduce pressure and temperature to save the reactor from a possible meltdown.Ĭritical core cooling systems failed at both reactors. Tokyo Electric Co., or TEPCO, Saturday began pouring seawater and boric acid into its Fukushima Daiichi power plant Unit 1 reactor, whose core partially melted.
