An explosion at a French nuclear waste processing plant that killed one person and injured four others sparked fears of a radioactive leak on Monday.

An emergency safety cordon was thrown around the Marcoule nuclear site near Nimes in the south of France immediately after a furnace used to melt nuclear waste exploded and caused a fire. It was lifted later in the day after France's nuclear safety agency, the Autorité de Sûreté Nucléaire (ASN), said there was no danger to the public.

Reports said the body of one male worker at the plant had been "found carbonised", but there was no evidence that the explosion had caused any radioactive leak, though the ASN admitted there was the "possibility of a leak of low-level radioactivity, but no shooting of radioactivity in the air". There was no information as to the cause of the explosion.

The accident came just a week after the French president, Nicolas Sarkozy, bucked the anti-nuclear trend following Japan's Fukushima disaster and pledged €1bn (£860m) of new investment in atomic power.

EAST LANSING, Mich. — Researchers at Michigan State University have unraveled the mystery of how microbes generate electricity while cleaning up nuclear waste and other toxic metals.

Details of the process, which can be improved and patented, are published in the current issue of the Proceedings of the National Academy of Sciences. The implications could eventually benefit sites forever changed by nuclear contamination, said Gemma Reguera, MSU microbiologist.

“Geobacter bacteria are tiny micro-organisms that can play a major role in cleaning up polluted sites around the world,” said Reguera, who is an MSU AgBioResearch scientist. “Uranium contamination can be produced at any step in the production of nuclear fuel, and this process safely prevents its mobility and the hazard for exposure.”

NRC Task Force Review of Insights from Fukushima

Sun, 2011-08-28 00:18 — Kathy Gilbeaux

United States Nuclear Regulatory Commission - July 12, 2011

The U.S. Nuclear Regulatory Commission (NRC) has released "Recommendations for Enhancing Reactor Safety in the 21^st Century: The Near-Term Task Force Review of Insights from the Fukushima Dai-ichi Accident." The Near-Term Task Force was established in response to Commission direction to conduct a systematic and methodical review of NRC processes and regulations to determine whether the agency should make additional improvements to its regulatory system and to make recommendations to the Commission for its policy direction, in light of the accident at the Fukushima Dai-ichi Nuclear Power Plant.

Nuclear Regulatory Commission's Japan Task Force Makes Its Report

On 11^th March 2011, northeast Japan was struck by a magnitude 9 earthquake and an ensuing tsunami. The Fukushima nuclear power plant was directly in the path of the tsunami and was also at the epicentre of some aftershocks. The US Nuclear Regulatory Commission established a Japan Task Force which was charged with identifying lessons that the USA should learn from the Fukushima incident.

The task force was led by Charles Miller and it came up with a set of twelve recommendations aimed at improving safety at US nuclear power plants (NPP) and re-evaluating the level of public health protection required to meet needs in the 21^st century.

Traces of Radiation Found in 2 Whales Off Japan

TOKYO (AP) — Japanese whalers caught two animals along the northern coast that had traces of radiation, presumably from leaks at a damaged nuclear power plant, officials said Wednesday.

Two of 17 minke whales caught off the Pacific coast of Hokkaido showed traces of radioactive cesium, both about one-twentieth of the legal limit, fisheries officials said.

They are the first whales thought to have been affected by radiation leaked from the Fukushima Dai-ichi nuclear plant since it was hit by a March 11 earthquake and tsunami.

"The levels are far below the limit, and the meat from the catch is safe for consumption," Fisheries Agency official Kosei Takekoshi said.

Simulation Fukushima Reactor 4-like Meltdown in a U.S. Nuclear Power Plant

Thu, 2011-06-23 09:08 — mdmcdonald

It has been proposed that there should be a serious game simulation of a Fukushima Dai-ichi nuclear power plant reactor 4-like accident in a U.S. power plant to test the U.S. public's preparedness and ability to utilize social media and government risk communication messaging to reduce health and human security concerns around U.S. nuclear plants. Many U.S. power plants, often close to major U.S. population centers like New York City and Omaha, Nebraska, share Japan's crippled Fukushima nuclear power vulnerability of storing spent fuel rods on site. The U.S. has not prepared the American public in projected plume areas for sheltering in place and evacuations that would dramatically reduce their risk in a Fukushima-like accident.

This week's loss of power during flooding at the Fort Calhoun nuclear power plant, near Omaha, Nebraska demonstrates that this problem is not theoretical. Although power was only cut to the plant for 90 minutes, if the power shortage had continued for over 28 hours or so, a catastrophic meltdown could have threatened Omaha, Nebraska with high-levels of radiation.

The Nation: Russia's Federal Atomic Energy Agency Claims a Near Catastrophic Meltdown of the Fort Calhoun Nuclear Power Plant in Nebraska

Thu, 2011-06-23 00:52 — mdmcdonald

This unusual story from Pakistan's "The Nation" claims that there has been a cover up of a near catastrophic meltdown for the Fort Calhoun nuclear power plant near Omaha, Nebraska. Evidence from the nuclear power plant and U.S. regulators indicate that the Pakistani story and Russian claims are significantly over-reaching. The flooding that caused a Fukushima reactor 4-like spent fuel rod cooling pond interruption of power led to a 90 minute interruption of power, but the temperature of the cooling pond and the water coverage of the spent fuel rods did not approach circumstances that would cause a meltdown, according to U.S. officials.
