Plant operator Tepco reveals meltdown and breach of pressure vessel, with Greenpeace warning against pumping water in. Greenpeace has urged Tepco to abandon plans to flood the container with water, given the likelihood that melted fuel had damaged it. Shaun Burnie, nuclear adviser to Greenpeace...

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...

According to the mainstream media, the Fukushima nuclear accident is all over. Just the opposite is happening. Historic high levels of radioactivity. Mega radiation released again. Japan admits Reactor 1 total melt-down, leak. #4 leaning, could collapse. #3 out of control. Population poisoned...

There must be a large leak," Junichi Matsumoto, a general manager at the utility also known as Tepco, told a news conference on Thursday. "The fuel pellets likely melted and fell, and in the process may have damaged ... the pressure vessel itself and created a hole," he added. Since the...

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...

* Post-Fukushima inspections found issues at U.S. plants * Plants must certify compliance with rules by June 10 * Additional certifications required in July * Industry says "well on its way" to providing answers * INPO president: "We cannot resort to business as usual" (Adds industry quotes...

New evidence suggests that nuclear chain reactions at the Fukushima power plant didn't end when the generators were initially shut down, following the March 11 earthquake. Technology Review explains why Tetsuo Matsui, a researcher at the University of Tokyo, thinks conditions inside two of...

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...

The recent 9.0-magnitude quake and tsunami in Japan triggered a number of explosions at the Fukushima No. 1 nuclear power plant, which caused the worst nuclear crisis since Chernobyl in 1986. The radiation levels in the building exceed expected levels reaching as high as 700 millisieverts per...

TOKYO (Dow Jones)--Eight workers and a government inspector entered the reactor building of the quake-hit Fukushima Daiichi nuclear complex's No. 1 unit early Monday to survey conditions inside, another step toward bringing the complex's three damaged reactors under control since they began...

TO CALL it a hot ticket might, in the circumstances, seem a tad tasteless. But no session at this year’s International Conference on Advances in Nuclear Power Plants, held in the south of France, was as well attended as the late-running special plenary hastily arranged to provide an update on...

Levels of radioactive substances have jumped in the Pacific seabed off Japan to as much as 1,000 times the normal readings, authorities have announced. Seabed samples collected near the Fukushima nuclear power plant, crippled by a massive earthquake and tsunami in March, contained radioactive...
