The Energy Department, dealing with twin setbacks in its long effort to deal with Cold War-era radioactive waste, said Tuesday it was stopping construction of a massive plant in South Carolina to handle surplus plutonium and proceeding with an investigation into a leak at a nuclear dump in New Mexico that exposed 13 workers to airborne plutonium. In releasing its fiscal 2015 budget, energy officials said they were stopping construction of the "mixed oxide fuel" plant at the Savannah River site in South Carolina.

The U.S. Energy Department said Tuesday it had opened an investigation into a leak of radioactive materials at a nuclear burial site near Carlsbad, N.M. The department shut down normal operations last week at its Waste Isolation Pilot Plant after radiation alarms sounded late Friday, when no one was in the underground facility. Officials at the site discounted any effect on human health, saying no radiation had escaped to the surface and no workers were exposed. So far, it is unknown what caused the release of radioactivity inside the repository, built in ancient salt beds 2,150 feet below the surface.

The canopies of kelp undulating in the surges off the coast of California camouflage a complex ecosystem of sharks, rock fish, crabs, urchins and anemones that blossom like colorful flowers on the forest floor. Now, Steven L. Manley, a biology professor at Cal State Long Beach, and Kai Vetter, head of applied nuclear physics at Lawrence Berkeley National Laboratory, have launched a campaign to monitor those groves for radioactive contaminants due to arrive later this year in ocean currents from Japan's damaged Fukushima nuclear power plant.

Radiation detected off the U.S. West Coast from the Fukushima Daiichi nuclear plant in Japan has declined since the 2011 tsunami disaster and never approached levels that could pose a risk to human health, seafood or wildlife, scientists say. Experts have been trying to dispel worries stemming from a burst of online videos and blog posts in recent months that contend radiation from Fukushima is contaminating beaches and seafood and harming sea...

MEXICO CITY - After a frantic search across a wide section of central Mexico, authorities said Wednesday that they had found a stolen truck that was transporting a large amount of dangerous radioactive material, a substance that can be used in making dirty bombs. The truck and its contents were found in the state of Mexico, about 20 miles north of the capital, not far from where they were stolen Monday. But the metal container with the radioactive material had been opened by the thieves, who then chucked it about half a mile from where they abandoned the truck, an official with the Mexican nuclear safety commission told The Times.

On a wind-swept plateau, underground steel tanks that hold the nation's most deadly radioactive waste are slowly rotting. The soil deep under the desert brush is being fouled with plutonium, cesium and other material so toxic that it could deliver a lethal dose of radiation to a nearby person in minutes. The aging tanks at the former Hanford nuclear weapons complex contain 56 million gallons of sludge, the byproduct of several decades of nuclear weapons production, and they represent one of the nation's most treacherous environmental threats.
