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.

Effect of Contaminated Soil on Food Chain Sparks Fears

Cesium absorption through roots may have long-term effect on farming

Six months after the nuclear meltdowns in Fukushima Prefecture, the public's awareness of the threat posed by radiation is entering a new phase: the realization that the biggest danger now and in the future is from contaminated soil.

The iodine-131 ejected into the sky by the Fukushima No. 1 power station disaster was quickly detected in vegetables and tap water — even as far away as Tokyo, 220 km south of the plant.

But contamination levels are now so low they are virtually undetectable, thanks to the short half-life of iodine-131 — eight days — and stepped up filtering by water companies.

But cesium is proving to be a tougher foe. The element's various isotopes have half-lives ranging from two to 30 years, generating concern about the food chain in Fukushima Prefecture, a predominantly agricultural region, as the elements wash fallout into the ground.

The root of the problem is, well — roots.

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.”

Japan Faces Costly, Unprecedented Radiation Cleanup

(Reuters) - Nearly six months after the world's worst nuclear crisis in 25 years at the Fukushima nuclear plant, Japan faces the task of cleaning up a sprawling area of radioactivity that could cost tens of billions of dollars, and thousands may not be able to return home for years, if ever.

Fuel core meltdowns at the facility in March, triggered by a huge earthquake and tsunami, released radioactive material into the air which mixed with rain and snow and covered dozens of towns as well as farmland and woods, mainly along the northeast coast of Honshu.

Tokyo has been slow to provide a plan for rehabilitation, leading some residents near the plant exposed to high levels of radioactive caesium in homes and food, have started their own cleanup instead of waiting for the government to act.

Bill Compiled to Decontaminate Radiation from Fukushima Nuclear Accident

asahi.com - August 17, 2011

The central government will decontaminate soil, vegetation and buildings exposed to radiation spread by the accident at the Fukushima No. 1 nuclear power plant.

The contents of a special measures bill to deal with environmental pollution from radioactive materials have been agreed to by the ruling Democratic Party of Japan as well as the opposition Liberal Democratic Party and New Komeito. The parties plan to submit the bill to the Diet next week so that it gains passage before the Diet session winds up Aug. 31.

Under the proposed legislation, the central government will also remove contaminated rubble.

As of now, there are no laws to deal with contamination of the environment by radioactive materials.

As such, it will become the first law to deal with this problem as the result of a nuclear accident.

The bill's objective is to reduce the health risk posed by radiation contamination.

The environment minister would have the authority to designate special areas that require decontamination measures.

Mountains of Debris Stand in the Way of Quake Reconstruction

The tsunami that followed the Great East Japan Earthquake left 22 million tons of debris and rubble scattered across three prefectures in the Tohoku region. No real steps toward restoration can be taken until it is removed. Last month, Prime Minister Naoto Kan's administration at long last introduced a bill to the Diet to place the national government in direct control of the cleanup. Will concentrated efforts to remove the debris now finally get underway?

At the end of June, disaster experts, representatives from the Environment Ministry and officials from affected municipal governments gathered at a conference in Sendai for a meeting on how to dispose of the debris. The gathering, organized by Japan Society of Material Cycles and Wast Management, a scientific group studying the debris problem, attracted 150 people, well above expected numbers, forcing organizers to change the venue to a larger room.

During the Q&A session, municipal government personnel peppered representatives from the environment ministry, which is responsible for dealing with the debris problem, with questions concerning the cleanup.

TOKYO —

The operator of Japan’s damaged Fukushima Daiichi nuclear power plant is building a huge tent to cover one of the worst-hit reactors, officials said Friday.

Officials hope the cover will keep radioactive materials that have already leaked from spreading, prevent rainwater seepage and offer a barrier from possible leaks or blasts in the future.

The tent is being erected to provide a temporary replacement for the No. 1 reactor’s outer housing shell, which was destroyed in an explosion caused by high pressure the day after Japan’s deadly earthquake and tsunami on March 11.

Construction of the tent and its foundation began this week, Koji Watanabe, a spokesman for the power utility, said Friday.

Japan: Government Releases Plan to Deal with Nuclear Ash

Fri, 2011-08-12 15:47 — Kathy Gilbeaux

The Daily Yomiyuri - August 12, 2011

The Environment Ministry has drafted a plan to bury the ash of incinerated radioactive debris and sludge that is contaminated with more than 8,000 becquerels of radioactive cesium per kilogram in a carefully regulated manner to prevent leakage in final disposal sites.

The ministry submitted the draft plan to the Disaster-Related Waste Safety Assessment Committee, its advisory body, on Wednesday. The ministry will officially decide its policy on how to bury the radioactive ash by the end of August at the earliest.

In June, the ministry announced it would allow ash with radioactive cesium levels measuring less than 8,000 becquerels per kilogram to be buried. At that time, the ministry advised that ash exceeding that amount be temporarily stored.

Regarding how to bury ash exceeding 8,000 becquerels, the draft plan released on Wednesday said it is necessary to ensure that the contaminated ash would not mix with rainwater or groundwater.

The draft plan has suggested several possibilities, such as using disposal sites with roofs to shield the ash from rain water, a drainage treatment system to prevent underground water from being contaminated, placing the ash in highly durable containers or solidifying ash with cement.

Environment Ministry Gets Nuke Role

Fri, 2011-08-12 15:35 — Kathy Gilbeaux

The Japan Times - August 12, 2011

                                  

Prime Minister Naoto Kan and his Cabinet members agreed Friday to set up a new agency in charge of nuclear safety under the Environment Ministry amid the crisis at the Fukushima No. 1 nuclear power plant.

The accord comes after the government announced last week its plan to create the new entity and said it was considering whether to place the agency under the wing of the Environment Ministry or the Cabinet Office.

The Cabinet Office was dropped as a candidate because of its "ties" with the Ministry of Economy, Trade and Industry, which loans officials to the office, according to government sources.

In a bid to undertake a major overhaul of Japan's nuclear regulatory structure, Kan has been calling to separate the current Nuclear and Industrial Safety Agency from the industry ministry, which promotes the use of atomic energy.

NISA has been criticized for lax government supervision of nuclear facilities and a slow response to the Fukushima plant crisis, which was triggered by the devastating March 11 earthquake and tsunami.
