Officials for Hanford Nuclear Reservation trying to determine if second giant tank containing radioactive waste is leaking

Officials for Hanford Nuclear Reservation trying to determine if second giant tank containing radioactive waste from production of plutonium for nuclear weapons is leaking | 26 April 2016 | (WA) Officials for the Hanford Nuclear Reservation are trying to determine if a second giant underground tank containing radioactive waste from the production of plutonium for nuclear weapons is leaking, the U.S. Department of Energy revealed on Tuesday. Air monitors attached to an aging tank known as AY-101 recently found radiation at higher than normal background levels, the agency said. A video inspection of the underground tank found no evidence that radioactive waste had leaked from the primary tank into the space between the two walls, Hanford officials said. A Hanford watchdog group on Tuesday contended the higher radiation found by the air monitors was evidence of a leak in a second tank.
