U.S. Department of Energy public bus tours have resumed in Oak Ridge after a two-year pause due to the COVID-19 pandemic.

The tours began running again on July 11, and they are scheduled to continue through November.

“The program is a longtime staple in the community, helping educate residents and visitors about the site’s rich history and current missions,” DOE said in an EM Update newsletter published Tuesday. (EM stands for environmental management.)

The tour program started in 1996 and has attracted tens of thousands of visitors from all 50 states, DOE said.

The three-and-a-half-hour tours allow visitors to see all three DOE sites on the Oak Ridge Reservation, including Oak Ridge National Laboratory (ORNL), Y-12 National Security Complex, and East Tennessee Technology Park.

The U.S. Department of Energy and cleanup contractor UCOR are preparing to demolish research reactor facilities at Oak Ridge National Laboratory.

Crews are nearing the final stages of deactivation inside two former research reactor facilities: the Bulk Shielding Reactor, known as Building 3010, and the Low Intensity Test Reactor, known as Building 3005, according to a newsletter published by DOE’s Office of Environmental Management. They are also beginning efforts at the Oak Ridge Research Reactor, known as Building 3042.

The work is overseen by DOE’s Oak Ridge Office of Environmental Management, or OREM.

These structures are located in the heart of ORNL, and their demolition will eliminate risks, clear land for research missions, and enhance access to a component of the Manhattan Project National Historical Park, the department said.

Teresa Frady

Teresa Frady, president of the Community Reuse Organization of East Tennessee, is the Spotlight Interview guest on this week’s episode of the Gone Fission Nuclear Report podcast, which covers U.S. Department of Energy environmental management activities around the nation.

Hosted by Michael Butler, the episode is available on all podcast platforms and can be accessed at www.gonefissionpodcast.com, a press release said.

Frady shared with Butler’s listeners CROET’s mission to help DOE transition underused assets such as land, buildingsm and equipment to private sector companies at the East Tennessee Technology Park, also known as the Heritage Center. She recently replaced Lawrence Young, who had served as CROET’s president and chief executive officer since its founding in 1995.

“Our partnership with DOE in transferring federal land helps the region with creation of quality jobs but also adds the property to Roane County and City of Oak Ridge tax rolls,” she said in the press release. “This helps the communities and saves the federal government money since DOE no longer has to maintain those assets.”

Innovation has been required as federal cleanup crews work to deactivate and demolish the final portion of the former Radioisotope Development Laboratory at Oak Ridge National Laboratory.

The structure is known as the East Cell Bank, and it is on the U.S. Department of Energy’s list of high-risk excess contaminated facilities, said a press release from DOE Office of Environmental Management. The East Cell Bank is located in the heart of ORNL, near ongoing research missions.

Workers with cleanup contractor UCOR characterized the final cell to identify potential radiological and hazardous contamination, the press release said. They conducted the work in stages under a six-story protective structure erected to ensure nearby facilities and ongoing research missions at ORNL aren’t impacted by the cleanup.

The crews began by taking surveys and readings from an opening at the front of the structure, the release said. They used long-reach tools and a specialized radiation detector. The detector overlays a radiation-intensity color map on a picture of the environment and identifies gamma-ray emitting nuclides and their locations.

The U.S. Department of Energy is upgrading a historic reactor in Oak Ridge to keep the facility safe until it can be demolished.

The reactor, the Molten Salt Reactor Experiment, is at Oak Ridge National Laboratory, and it was shut down nearly 50 years ago. At some point, the MSRE will be deactivated, and that will save about $5 million in annual operating costs, a press release said.

The work is being overseen by the DOE Oak Ridge Office of Environmental Management.

“We have the important responsibility of keeping it safe until major cleanup operations begin,” said Nathan Felosi, EM’s ORNL portfolio federal project director. “The latest round of projects is making sure that’s the case and achieving considerable cost savings to taxpayers.”

Note: This story was updated at 9 a.m. Feb. 4.

Two federal agencies have agreed to build a K-25 Viewing Platform at the historic site in west Oak Ridge that was used to enrich uranium for nuclear weapons and nuclear power plants during World War II and the Cold War. The design is expected to be complete in March and the building completed by the end of 2023.

The construction agreement for the viewing building at the former K-25 site was signed by the U.S. Department of Energy’s Oak Ridge Office of Environmental Management and U.S. Army Corps of Engineers.

The viewing platform will give visitors a view of the large 44-acre footprint of the former K-25 Building. K-25, which was the world’s largest building, was erected during World War II as part of the Manhattan Project to help enrich uranium for the world’s first atomic bombs during World War II. The K-25 Building was demolished in 2013, and many other structures at the site have been removed as the federal government turns over property for private development.

The K-25 Building site itself is now part of the Manhattan Project National Historical Park. That project commemorates the workers, equipment, and processes used during the Manhattan Project in Oak Ridge, Tennessee; Hanford, Washington; and Los Alamos, New Mexico.

The K-25 Viewing Platform and associated exhibits are the final components of a multi-project agreement that the Oak Ridge Office of Environmental Management signed in 2012, clearing the way for demolition of the North Tower of the mile-long, U-shaped K-25 Building. The projects commemorate the history of the K-25 site, which has also been known as the Oak Ridge Gaseous Diffusion Plant.

The Oak Ridge team that mostly cleaned up the former K-25 site, demolishing five large gaseous diffusion buildings and more than 500 structures, has received a Secretary’s Achievement Award from U.S. Energy Secretary Jennifer Granholm. The work was done ahead of schedule and under budget, the U.S. Department of Energy said.

Granholm honored the DOE Office of Environmental Management team from Oak Ridge in a virtual ceremony Wednesday, a press release said.

K-25 was used to enrich uranium for nuclear weapons and commercial nuclear power plants from World War II to the 1980s.

It was the first removal of a uranium enrichment complex, and it cleared 13 million square feet of deteriorated, contaminated structures from the site, the press release said.

“The Secretary’s Achievement Award honors a group or team of DOE employees and contractors who accomplish significant achievements on behalf of the department, demonstrating cooperation and teamwork in attaining their goals,” the press release said. “The award was given to the Oak Ridge Vision 2020 Project Team based on its achievements from 2020.”

Crews are nearly finished deactivating the second of three collections of old, mercury-contaminated equipment around the Alpha-4 facility at the Y-12 National Security Complex at Oak Ridge, a press release said.

The project addresses potential environmental risks and moves the U.S. Department of Energy Office of Environmental Management a step closer to preparing one of Y-12’s largest high-risk contaminated facilities for demolition, the press release said.

The column exchange, or COLEX, structures are connected to the four-story 500,000-square-foot Alpha-4 building, which was used for uranium separation from 1944 to 1945. Workers finished installing the COLEX equipment in 1955 for lithium separation, a process that required large amounts of mercury. A significant amount of the mercury was lost into the equipment, buildings, and surrounding soils, and its cleanup is one of EM’s top priorities.

Demolition work at a former radioisotope laboratory in Oak Ridge could be complete this spring.

The U.S. Department of Energy Oak Ridge Office of Environmental Management and UCOR announced earlier this year that UCOR, a contractor, had begun removing the two remaining structures at the former Radioisotope Development Lab at Oak Ridge National Laboratory.

“This project launches our next phase of major demolition and cleanup at ORNL,” said Nathan Felosi, OREM’s portfolio federal project director for ORNL. “Our work is eliminating contaminated structures, like this one, that are on DOE’s list of high-risk facilities and clearing space for future research missions.”

Known as “hot cells,” the structures being demolished are heavily shielded concrete rooms that provided researchers protection from highly radioactive material during the years the laboratory was operational, a press release said.
