Radiation levels at the stricken Fukushima Daiichi nuclear power plant in Japan are still high but may be tapering off, a senior U.S. nuclear official said Sunday. Indications from the plant, which houses six nuclear reactors, were levels in the range of hundreds of millisieverts per hour, said Gregory Jaczko, chairman of the U.S. Nuclear Regulatory Commission. The duration of those levels was unclear. The exposure limit for Japanese workers was recently raised to 250 millisieverts per year.

A fire that destroyed a cooling tower at the nation's largest nuclear power plant did not involve radiation, a spokesman for the Tennessee Valley Authority said Sunday as officials arrived to investigate the cause of the blaze. TVA spokesman Craig Beasley said a team of TVA management officials was starting its investigation of the Saturday fire, which swept through a four-story tower at the Browns Ferry nuclear plant. No injuries were reported in the blaze at the three-reactor facility.

Operators of the troubled Rancho Seco nuclear power plant have been advised by an analyst to permanently close the plant rather than continue costly efforts to restart it after a two-year shutdown. "Our analysis shows closing the plant would save $200 million to $1 billion over the next 12 years," energy policy analyst Joseph Kriesberg told the Sacramento Municipal Utility District Board of Directors.

A meltdown may be occurring at one of the reactors at an earthquake-damaged nuclear power plant in northeast Japan, a government official told CNN Sunday morning Japan time. "There is a possibility, we see the possibility of a meltdown," said Toshihiro Bannai, director of the international affairs office of Japan's Nuclear and Industrial Safety, in a telephone interview with CNN from the agency's Tokyo headquarters.

Congressmen on Friday denounced a proposed Nuclear Regulatory Commission rule change on evacuation planning as a "declaration of war" against states' rights and vowed a legislative counterattack. Congressmen from Massachusetts, New York and Ohio said that the states' power to protect citizens living near nuclear plants would be wiped out by the commission's staff proposal.

Engineers began injecting nitrogen into one of the reactors at the troubled Fukushima Daiichi nuclear power plant Wednesday evening as radiation levels in seawater near the plant dropped and a new report from the U.S. Nuclear Regulatory Commission suggested that the plant may face even more troubles in the future. Officials from the United Nations, meanwhile, said that even though the situation in Japan is more serious than the U.S. faced after the Three Mile Island accident in Pennsylvania in 1979, the group does not expect severe health consequences.

Concern over the safety of the San Onofre nuclear power plant is growing among Orange County cities closest to the facility, which has been shut down since January because of system failures. Officials in nearby San Clemente and Laguna Beach - both within 20 miles of the San Onofre facility - have registered their fears after significant wear was found on hundreds of tubes carrying radioactive water inside the plant's generators. Residents in the Orange County beach towns for years have lived with the twin-domed nuclear plant as a backdrop.

At least one person was killed and four injured when a furnace exploded Monday at the Marcoule nuclear waste treatment site in southern France. Authorites say there was no radioactive leakage to the outside. Evangelia Petit of the Agency for Nuclear Safety confirmed the explosion but declined to provide further details, according to the Associated Press. The Marcoule nuclear plant is located in Langedoc Roussillon, in southern France, near the Mediterranean Sea. The site of the blast does not reportedly contain any nuclear reactors.
