The new Mercury Treatment Facility at the Y-12 National Security Complex will help reduce the amount of mercury that gets into East Fork Poplar Creek and allow the demolition of four large buildings where mercury was used to help make nuclear weapons during the Cold War, officials said Monday.

Mercury contamination is one of the biggest problems remaining from the Cold War, U.S. Senator Lamar Alexander said during a groundbreaking ceremony on Monday morning. Alexander, a Tennessee Republican, first announced the new treatment facility at Y-12 more than four years ago.

“In May 2013, I came to Oak Ridge to announce that a new water treatment facility would be built at Y-12 at the head of the East Fork Poplar Creek to prevent mercury that was once used to make nuclear weapons from getting into our waterways,” Alexander said. “That day, I made a personal commitment to address one of the biggest problems we have from the Cold War era—mercury contamination—and help fund a solution. Today, I am proud to see that we are breaking ground on the new water treatment facility.”

Site preparation for the new Mercury Treatment Facility is expected to start this year, with the rest of construction beginning in late 2018. The facility is expected to start operating in late 2022.

The treatment plant will allow workers to demolish four large buildings where mercury, a toxic metal, was once used: Alpha 2, Alpha 4, Alpha 5, and Beta 4. Work on those buildings, mostly on the west side of Y-12, could start by 2024. [Read more…]

Site preparation could start later this year for the Mercury Treatment Facility at the Y-12 National Security Complex as the U.S. Department of Energy prepares for demolition and cleanup work at the nuclear weapons plant.

DOE’s Oak Ridge Office of Environmental Management, or OREM, expects to complete demolition and cleanup work at the East Tennessee Technology Park, the former K-25 site, in 2020. It will then focus on the large-scale demolition work at Y-12.

Among the Y-12 buildings that could be demolished are Alpha 4, Alpha 5, and Beta 4, all large buildings where mercury, a toxic metal, was once used. The buildings used mercury to separate lithium for nuclear weapons. The lithium separation operations started in 1955 and ended in 1963.

But before that cleanup work can begin, OREM needs the Mercury Treatment Facility. The plant was first announced at a press conference featuring U.S. Senator Lamar Alexander, a Tennessee Republican, about four years ago, in May 2013.

“This water treatment plant is a major step in addressing one of the biggest problems we have from the Cold War era—mercury once used to make nuclear weapons getting into our waterways,” Alexander said at the time. [Read more…]

Construction on a mercury treatment plant at the Y-12 National Security Complex could start in 2018 and cost $146 million, a federal official said Wednesday.

The plant would treat mercury contamination that originates in the West End Mercury Area at Y-12, flows through storm drains, and enters Upper East Fork Poplar Creek at a point known as Outfall 200. East Fork Poplar Creek flows through Oak Ridge.

The U.S. Department of Energy has evaluated several alternatives for treating the mercury, including doing nothing. But DOE prefers an option that would treat 3,000 gallons of contaminated water per minute and store two million gallons of stormwater. It could reduce the flow of mercury, a toxic metal, by an estimated 84 percent. [Read more…]
