The U.S. Department of Energy estimates it could cost at least $7.2 billion to convert and dispose of tens of thousands of cylinders of depleted uranium hexafluoride, a dangerous, corrosive waste byproduct of the uranium enrichment process. Some of the waste came from the former K-25 site in Oak Ridge and is now stored in Ohio, but a portion of the converted depleted uranium could eventually be returned to Oak Ridge for use in nuclear weapons.

DOE picks Idaho for nuclear test reactor

The U.S. Department of Energy has decided to build a nuclear test reactor at Idaho National Laboratory to study fuels and materials.

Besides INL, Oak Ridge National Laboratory had been considered as a potential site for the Versatile Test Reactor. ORNL remains one of five national laboratories that are partners on the project. DOE said building the test reactor at INL was its preferred alternative.

At ORNL, the Versatile Test Reactor would have been at a relatively undeveloped site previously considered for other projects about a mile east of the ORNL main campus. It would have required a new hot cell and a facility for post-irradiation examination and the conditioning of spent nuclear fuel for disposal. It would also have used existing facilities at ORNL, including the Irradiated Fuels Examination Laboratory and the Irradiated Material Examination and Testing Facility.

DOE said building the Versatile Test Reactor at either INL or ORNL would have small environmental consequences, but overall, the consequences would be less at the INL site. Among the reasons: A smaller area would be temporarily disturbed and permanently occupied at INL because of the need to build a new hot cell facility at ORNL. Unlike the INL site, the ORNL location abuts wetlands that would have to be managed or avoided under the Clean Water Act and Tennessee regulations. The removal of trees at ORNL would result in the loss of roosting habitat for sensitive bat species. And although small at both locations, the potential radiological impacts would be lower at INL because the Versatile Test Reactor would be farther from the site boundary and population density is lower near INL than ORNL.

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.

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.

Cymbeline “Bem” Culiat

A former molecular geneticist at Oak Ridge National Laboratory will discuss regenerative medicine and a potential treatment for severe COVID-19 disease patients and those who struggle with “long haul” symptoms.

The talk by Cymbeline “Bem” Culiat—co-founder, president, and chief science officer of NellOne Therapeutics in Knoxville—will speak virtually to Friends of ORNL at noon Tuesday, February 8.

“While at ORNL, Culiat discovered the role of the NELL1 signaling protein in fostering the growth and maturation of musculoskeletal and cardiovascular tissues in mice and other mammals, including humans,” a press release said. “Her biotech company focuses on using her discovery to advance regenerative medicine, which involves replacing, engineering, or regenerating human or animal cells, tissues, or organs to promote healing and restore normal function. In contrast, traditional medicine typically provides treatment of symptoms rather than addressing root causes.”

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.”
