Cleanup crews started a $4.7 million project this month to reduce maintenance and operations costs at the Molten Salt Reactor Experiment, which was shut down 50 years ago at Oak Ridge National Laboratory.

The project is expected to save nearly $25 million in costs, the U.S. Department of Energy Office of Environmental Management said in an “EM Update” published Tuesday.

The cost-reduction project will relocate employees stationed at the decades-old facility. Personnel currently housed in the building will move to other site locations to help with other projects, the “EM Update” said.

The project is expected to enhance the facility’s electrical distribution, sump pump, fire suppression, and monitoring systems.

“Although it was shut down 50 years ago, certain systems within the reactor building have continued to operate to keep the facility safe and stable until it can be demolished,” said the “EM Update,” with the Oak Ridge story contributed by Mike Butler. [Read more…]

The partial shutdown of the federal government does not affect state oversight of the federal cleanup program in Oak Ridge, a state official said Thursday.

At this time, the federal shutdown has no impact on the Tennessee Department of Environment and Conservation, said Kim Schofinski, TDEC deputy communications director. That means state oversight of the Oak Ridge cleanup program is not currently affected. The Oak Ridge sites include East Tennessee Technology Park (the former K-25 site), Oak Ridge National Laboratory, and Y-12 National Security Complex. [Read more…]

The design is complete and funding is available for the construction of an Equipment Building and Viewing Tower that will help commemorate the history of the K-25 Building, once the world’s largest building under one roof.

K-25 was built in Oak Ridge during World War II to help enrich uranium for the Manhattan Project. That was a top-secret federal program to build the world’s first atomic weapons. During the war, Oak Ridge enriched the uranium for “Little Boy,” the first atomic bomb used in wartime. “Little Boy” was detonated over Hiroshima, Japan, on August 6, 1945, shortly before the end of World War II.

After the war, the four-story, 44-acre K-25 Building and four other large buildings at the K-25 site continued to use a process known as gaseous diffusion to enrich uranium for atomic weapons and commercial nuclear power plants. Officials say the K-25 site, which is in west Oak Ridge, helped win the Cold War.

After decades of use, the K-25 site was shut down in the mid-1980s, and as part of a cleanup effort in recent years, the five large gaseous diffusion buildings have been demolished. But the history of the K-25 building and the site will live on in a History Center on the second floor of Oak Ridge Fire Station Number 4, which is next to K-25’s concrete slab, and at the Equipment Building and Viewing Tower, which will be just west of the History Center.

The History Center, Equipment Building, and Viewing Tower will be on the south side of the former K-25 Building. The site is now known as Heritage Center or East Tennessee Technology Park. [Read more…]

The Anderson County Commission will hold a workshop today (Monday, January 7), starting at 6 p.m., to discuss the U.S. Department of Energy’s proposed construction and operation of a new hazardous waste disposal facility on the federal reservation in Oak Ridge.

The purpose of the meeting is to allow commissioners, officials, and residents to provide comments before the deadline for public comment on Wednesday January 9, on the proposed Environmental Management Disposal Facility (EMDF). The deadline was pushed back to this month after officials requested more time to look over the information.

David Adler, director of the Quality and Mission Support Division for the DOE’s Oak Ridge Office of Environmental Management, will attend Monday’s meeting, according to WYSH Radio in Clinton. [Read more…]

Tennessee officials have approved the demolition of two large buildings at the Biology Complex at the Y-12 National Security Complex.

The Biology Complex once housed more people with doctorates than anywhere in the world, according to the U.S. Department of Energy. DOE has said the men and women who worked there radically enhanced the world’s knowledge in biology, including the discovery of the Y chromosome.

Y-12 announced in December that the Tennessee Historical Commission had approved the demolition of the two buildings: Buildings 9207 and 9210. The buildings date back to the Manhattan Project, a top-secret federal program to build the world’s first atomic weapons during World War II. Oak Ridge was part of that project.

The demolition work at the Biology Complex is being overseen by the U.S. Department of Energy’s Oak Ridge Office of Environmental Management. [Read more…]

The U.S. Department of Energy is not affected by the partial government shutdown that started at midnight, and DOE employees and contractors, including in Oak Ridge, are expected to continue their normal work schedules.

”The partial government shutdown does not impact Department of Energy facilities,” federal officials said in a statement. “DOE’s fiscal year 2019 appropriations bill was approved by Congress and signed by the president in September. DOE employees and contractors are expected to continue to report to work according to their usual work schedule.”

Among the DOE sites and operations in Oak Ridge are East Tennessee Technology Park, Oak Ridge Institute for Science and Education, Oak Ridge National Laboratory, Oak Ridge Office, Oak Ridge Office of Environmental Management, Office of Scientific and Technical Information, and Y-12 National Security Complex. Y-12 is overseen by the National Nuclear Security Administration, a DOE agency. [Read more…]

Three women received the Muddy Boot Award and Postma Young Professional Medals presented by the East Tennessee Economic Council at its annual awards luncheon on Friday, December 14.

The Muddy Boot Award was created in the 1970s to honor individuals who have gone above the call of duty—like those who served the nation during the Manhattan Project—to make the community, the state of Tennessee, and the nation a better place to live and work, a press release said. More than 90 people have received the award. A full list of recipients and more information about the honor can be found on the ETEC website at www.eteconline.org.

Lawrence Young, founding president and chief executive officer of the Community Reuse Organization of East Tennessee, presented the Muddy Boot Award.

Sherry Browder, currently the re-industrialization manager for URS | CH2M Oak Ridge LLC (UCOR) at the East Tennessee Technology Park and a career environmental management specialist, was awarded the Muddy Boot Award for, among other activities, her work to transform the former gaseous diffusion site to an industrial asset in Oak Ridge and Roane County, the press release said.

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…]
