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...

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...

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...

residents of Japan have good cause to mistrust the media, TEPCO officials, and members of their government when it comes to assurances about radiation levels, plutonium dispersal, and the related health risks. Americans also have good cause to mistrust these same sort of assurances issued to...

77-year-old Michio Ishikawa of the Japan Nuclear Technology Institute on the situation at Fukushima I Nuke Plant, as he appeared on Asahi TV on April 29. As I watched the video, I started to like Mr. Ishikawa, who continues to believe in the safety of nuclear power generation. He didn't mince...

Furious parents in Fukushima have delivered a bag of radioactive playground earth to education officials in protest at moves to weaken nuclear safety standards in schools. Children can now be exposed to 20 times more radiation than was previously permissible. The new regulations have prompted...

proponents of reactors have spent some $645 million in the last decade lobbying Congress for more subsidies. ….A critical moment is coming soon, when Obama goes to Congress to request an additional $36 billion in loan guarantees for new nukes in his 2012 budget.With them, America’s atomic...

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...

TEPCO has been pouring water into the reactor vessels containing the rods since the disaster to cool them as an emergency measure. [ID:nL3E7FI0C7] In a further step towards a cold shutdown, TEPCO is filling the containment vessel -- an outer shell of steel and concrete that houses the reactor...

So now the Japanese have told us they made a mistake in calculating the actual amount of radioactivity being spewed out into the enviroment . So when they dumped all that , low level radioactive water into the, Pacific are they sure it was low level ? If they can make a mistake once I am sure...

A highly radioactive block of cement capable of killing anyone who spends more than 6 hours near it has been found outside the Fukushima nuclear power plant. Debris with similar radiation is believed to be spread around the nuclear power plant. Similar highly radioactive debris is spread around...
