Nuclear Power & Radiation

"LOS ANGELES — Unusual wear has been found on hundreds of tubes that carry radioactive water at Southern California’s San Onofre Unit 2 nuclear plant, raising questions about the integrity of equipment the company installed in a multimillion-dollar makeover in 2009.

The disclosure came two days after a tube leak at the plant’s other unit prompted operators to shut down the reactor as a precaution. A tiny amount of radiation could have escaped, but officials say workers and the public were not endangered.

"The two chairmen of a study group established after the Obama administration killed a plan for a nuclear waste repository in Nevada appeared before a House subcommittee on Wednesday to explain a proposed solution to the enduring waste dilemma. They found their idea tough to sell. Last week the so-called Blue Ribbon Commission on America’s Nuclear Future released a report calling for a new approach to finding a site, based on local consent rather than Congressional dictate."

"Canada’s Nunavut Territory is the largest undisturbed wilderness in the Northern Hemisphere. It also contains large deposits of uranium, generating intense interest from mining companies and raising concerns that a mining boom could harm the caribou at the center of Inuit life."

"TOKYO -- The temperature fell to minus 8.7 degrees Celsius on Sunday morning near Japan's crippled nuclear power plant, causing water pipes and valve seals to rupture, leaking tons of water."

"Workers at the Fukushima Daiichi nuclear plant discovered Sunday that the damaged pipes spilled nearly eight tons of water from 14 locations. Two additional water leaks were discovered today, according to plant operator Tokyo Electric Power Company.

"U.S. law enforcement agencies are exposing people to radiation in more settings and in increasing doses to screen for explosives, weapons and drugs. In addition to the controversial airport body scanners [2], which are now deployed for routine screening, various X-ray devices have proliferated at the border, in prisons and on the streets of New York. Not only have the machines become more widespread, but some of them expose people to higher doses of radiation. And agencies have pushed the boundaries of acceptable use by X-raying people covertly, according to government documents and interviews."

"The United States must urgently work to find a new central site to house its spent nuclear fuel and probe whether Japan's nuclear disaster has any safety implications for storage at the country's plants, a federal panel said on Thursday."

"Japan's energy minister admitted on Tuesday that no records were kept of top level discussions in the critical early days on how to respond to the world's worst nuclear disaster in 25 years."
