As a team from the Link Removed - Invalid URL visits Tokyo Electric Power Co.’s crippled nuclear plant today, academics warn the company has failed to disclose the scale of radiation leaks and faces a “massive problem” with contaminated water. The utility known as Tepco has been pumping...

A nuclear waste disposal facility at the crippled Fukushima Daiichi power plant will be filled up in several days with radioactive floodwater diverted from near its No. 2 and 3 reactors, officials of Tokyo Electric Power Co., the plant's operator, said Monday. The operator, known as TEPCO...

Let's hope we do not have another tsunami then ! A giant water-storage barge has arrived at Japan's quake-hit Fukushima Daiichi nuclear plant to store highly radioactive waste water from the basement of a reactor building, Kyodo news reported on Saturday. The plant was heavily damaged by the...

Hiroaki Koide of Kyoto University: "No One Knows How Fukushima Could Be Wound Down" As the Corium May Be Melting Through the Foundation "So says Hiroaki Koide of Kyoto University Research Reactor Institute, in a telephone interview on May 19 with independent video-journalist Tetsuo Jinbo of...

The China Syndrome refers to a scenario in which a molten nuclear reactor core could could fission its way through its containment vessel, melt through the basement of the power plant and down into the earth. While a molten reactor core wouldn't burn "all the way through to China" it could enter...

TOKYO (Nikkei)--In light of indications that damage to the No. 1 reactor at the Fukushima Daiichi nuclear power plant is worse than expected, Tokyo Electric Power Co. (9501) is expected to take a fresh approach to cooling down the fuel rods by installing equipment to circulate water that has...

Japanese officials have found an Olympic swimming pool-sized pond of radioactive water in the basement of a unit at the Fukushima nuclear plant crippled by the March earthquake and tsunami. The discovery has forced officials to abandon their original plan to bring the No 1 reactor under...

Japanese officials are readying a new approach to stabilizing a reactor at a nuclear plant crippled by an earthquake and tsunami after discovering a leak from the containment vessel of enough radioactive water to fill an Olympic swimming pool. The discovery has forced officials to abandon...

No one knew it was leaking until a worker found it on May 11. The amount of radioactive materials in the leaking water was far less than the pit water gushing from the Reactor 2 back in early April. Reactor 3 uses MOX fuel. TEPCO announced on May 11 evening that a high concentration of...

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...

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...

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...

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...

Fukushima, May 1 (Jiji Press)--High levels of radioactive cesium have been found in sewage sludge in Fukushima Prefecture, northeastern Japan, the prefectural government said Sunday. The sludge at a treatment center in Koriyama had 26,400 becquerels of radioactive cesium per kilogram. Slag...

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...
