Tokyo – The operator of Japan’s stricken Fukushima Dai-Ichi nuclear power plant says fire broke out again at its No. 4 reactor unit because the initial blaze was not completely extinguished.
Tokyo Electric Power Co. says the new blaze flared early Wednesday in the outer housing of the reactor’s containment vessel. Fire fighters are trying to put out the flames.
On Tuesday, a fire broke out in the reactor’s fuel storage pond — an area where used nuclear fuel is kept cool — causing radioactivity to be released into the atmosphere.
Officials are struggling to address the failure of safety systems at several of the plant’s reactors after Friday’s massive earthquake and tsunami.
