7 leaks found in Hanford's oldest double-walled tank

RICHLAND, Wash. - Inspectors at the Hanford Nuclear Reservation have found seven leaks in the site's oldest double-walled radioactive waste storage tank.Tank AY-102 was known since 2012 to have a slow leak from its inner shell into the space between its inner and outer walls.The Tri-City Herald reports that the tank, which once held 744,000 gallons of waste, had been emptied of all but 19,000 gallons by February.Then an inspection was done with video cameras.

Contamination at Hanford tank did not come from leak

RICHLAND, Wash. (AP) - Radioactive contamination found on a piece of equipment on the Hanford Nuclear Reservation was not the result of a leak in an underground nuclear waste storage tank.The U.S. Department of Energy said Wednesday that an analysis has ruled out that the contamination came from a leak within double-walled tank AZ-101.The department and its contractor are now looking at other potential sources, such as historical contamination from previous work at the tank.
