The U.S. Department of Energy says just one of the older single-walled storage tanks at the Hanford site appears to be actively leaking.
RICHLAND, WA - The U.S. Department of Energy says just one of the older single-walled storage tanks at the Hanford site appears to be actively leaking.
The Department of Energy's Office of River Protection tank farm contractor, Washington River
Protection Solutions, has determined that 19 of the 20 single shell tanks showing decreased liquid levels at the Hanford Site are not actively leaking. The one tank that was identified as leaking, T-111, appears to be stabilizing.
Earlier this year, it was believed that six single shell tanks were leaking.
The underground tanks contain radioactive wastes left over from the production of plutonium for nuclear weapons.
The Energy Department said Wednesday that the one tank that is leaking, known as T-111, appears to be stabilizing.
The agency says evaporation accounts for the loss of fluid in some tanks.
As many as 67 tanks are suspected of having leaked in the past. But leaking was believed to end when most liquids were removed from the single-walled tanks in 2004.
The DOE issued this statement Wednesday, "The cleanup of tank waste at Hanford's nuclear facilities and protection of workers, the public and the
environment remains a high priority for the Department. We will continue to keep the State of Washington, Congress and other key stakeholders apprised of the situation as we continue to monitor the liquid levels inside the single shell tanks"
