Crews start work for Mercury Treatment Facility at Y-12

Work began in June to build the Mercury Treatment Facility at the Y-12 National Security Complex.

The Mercury Treatment Facility will allow the U.S. Department of Energy to clean up and demolish several large Y-12 buildings that used mercury to separate lithium for nuclear weapons during the Cold War in the 1950s and 1960s. The facility is expected to help reduce the amount of mercury in East Fork Poplar Creek, which flows through Oak Ridge.

DOE announced in December that it had awarded a $91 million contract to build the Mercury Treatment Facility. The contract, which could be in place for up to four years, was awarded to APTIM-North Wind Construction JV LLC.

A groundbreaking was held at the site in November 2017, and site preparations were completed by December 2018.

The U.S. Department of Energy announced Tuesday that it has completed the site preparations for the construction of the Mercury Treatment Facility at the Y-12 National Security Complex.

The Mercury Treatment Facility will allow DOE to clean up and demolish several large Y-12 buildings that used mercury to separate lithium for use in nuclear weapons during the Cold War (in the 1950s and 1960s). It’s part of a large-scale cleanup and demolition project at Y-12 and an effort to reduce the amount of mercury in East Fork Poplar Creek, which flows through Oak Ridge.

DOE announced on Tuesday, December 4, that it had awarded a $91 million contract to build the Mercury Treatment Facility at Y-12. The contract, which could be in place for up to four years, was awarded to APTIM-North Wind Construction JV LLC.

DOE said early site preparation activities were started by other contractors in December 2017. A groundbreaking was held at the site in November 2017, and UCOR, DOE’s lead cleanup contractor in Oak Ridge, began work at the treatment facility site with a subcontractor after the groundbreaking, the DOE Oak Ridge Office of Environmental Management said in a story published Tuesday in an EM Update.

The Mercury Treatment Facility will have two components: a headworks facility and a treatment plant connected by a pipeline. The headworks facility will capture creek flow on the west end of Y-12, store excess stormwater collected during large rainfalls, remove grit, and pump water through the pipeline to the treatment plant on the east side of Y-12. The treated water will then flow into East Fork Poplar Creek. [Read more…]
