Fuel rods in the No 1 reactor of Japan's Fukushima No 1 nuclear power plant may have mostly melted and dropped to the bottom of the pressure vessel as the water level in the vessel has been found to be significantly lower than thought, Tokyo Electric Power Co. said Thursday (May 12). The fuel...

Reuters) - One of the reactors at Japan's crippled Fukushima nuclear power plant has a hole in its main vessel following a meltdown of fuel rods, leading to a leakage of radioactive water, its operator said on Thursday. The disclosure by Tokyo Electric Power Co (TEPCO) is the latest...

Tokyo Electric Power Co. said fuel rods are fully exposed in the No. 1 reactor at its stricken Fukushima Dai-Ichi nuclear plant, setting back the utility’s plan to resolve the crisis. The water level is 1 meter (3.3 feet) below the base of the fuel assembly, Junichi Matsumoto, a general...

A month has elapsed since the emergency at Fukushima began. But what exactly has gone on there and what are the priorities now? One way of looking at the drama that has unfolded around the Fukushima Daiichi nuclear reactors is as a narrative with one central plot, and a number of...

TOKYO — Workers at the crippled Fukushima Daiichi nuclear power plant adjusted measuring gauges Tuesday as part of the process to flood the vessel containing the No. 1 reactor with water and create a system to keep the fuel inside cool. But the working environment remains tough due to...

TOKYO: Highly-toxic plutonium has been found in soil in five separate locations at the crippled Fukushima Nuclear Power Plant in northeast Japan, the facility's operator said Tuesday, which has caused global concern about the growing severity of the crisis at the leaking plant. Owner and...

A concentration of radioactive water in the basement of the No. 4 reactor's turbine building at the crippled Fukushima No. 1 Nuclear Power Plant became abnormally high, reaching a maximum of 250 times normal monthly levels, according to Tokyo Electric Power Co. (TEPCO) on April 26. Radioactive...

Fukushima is going to dwarf Chenobyl. The Japanese government has had a level 7 nuclear disaster going for almost a week but won’t admit it. The disaster is occurring the opposite way than Chernobyl, which exploded and stopped the reaction. At Fukushima, the reactions are getting worse. I...

Engineers battling to contain the crisis at Japan's Fukushima nuclear power plant appeared to have turned an important corner last night after they stopped highly radioactive water from leaking into the ocean from one of the facility's crippled reactors. Workers struggling to halt the leaks...

Radioactive water is leaking into the sea from a 20-centimetre (8-inch) crack in a containment pit at Japan's quake-hit Fukushima nuclear plant, its operator Tepco has said. The crack under reactor 2 may be the source of recent radiation in coastal waters, Tepco officials said. Tepco is...

The Guardian reports that Japanese engineers have "lost the race" to prevent a nuclear meltdown. Apparently reactor number 2 has melted through its containment vessel, onto the concrete floor underneath. According to the expert quoted in the piece, the fuel will now run out like lava, "and that...

Japan has finally conceded it has lost the battle to contain radiation at four of its crippled reactors and they will be closed down. Details of what that will entail have yet to be revealed, but officials said it would mean switching off all power and abandoning attempts to keep the nuclear...

Of the 31 nations and regions with nuclear power plants, Japan is the most at risk of being hit by an earthquake. Particularly worrisome is the fact that Japan has lots of nuclear power plants and nuclear power plants and nuclear treatment facilities are built in earthquake-prone areas. The...

Link Removed Tokyo. The radioactive core in a reactor at the crippled Fukushima nuclear power plant appears to have melted through the bottom of its containment vessel and on to a concrete floor, experts say, raising fears of a major release of radiation at the site, the Guardian reported. The...
