"RICHLAND, Washington, August 20, 2012 (ENS) – For the first time, a leak of highly radioactive waste has been detected from a double-shelled tank at the Hanford Nuclear Site in central Washington state."

"The public interest group Hanford Challenge Friday released disclosed a memo from U.S. Department of Energy inspectors to the Washington State Department of Ecology detailing the leak.

Dated August 14, the memo acknowledges a highly-radioactive chemical waste leak that was detected in early August from Tank AY-102 on the floor of the “annulus,” the space between the two walls of the double-shell tank."
