OLYMPIA, Wash. (AP) - A tank that holds radioactive liquids is leaking at the nation's most contaminated nuclear site, Washington Gov. Jay Inslee said Friday, raising concerns about the integrity of other storage facilities at the Hanford Nuclear Reservation.
The U.S. Department of Energy said liquid levels are decreasing in one of 177 underground tanks at the nuclear reservation. Monitoring wells near the tank have not detected higher radiation levels, but Inslee said the leak could be in the range of 150 gallons to 300 gallons over the course of a year and creates a long-term threat that could impact groundwater or rivers.
"I am alarmed about this on many levels," Inslee said at a Friday afternoon news conference. "This raises concerns, not only about the existing leak ... but also concerning the integrity of the other single shell tanks of this age."
