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.
