Crews are making significant progress on the construction of the K-25 viewing platform at the Oak Ridge Reservation in Tennessee, the Department of Energy’s Office of Environmental Management announced on August 20. When completed next year, the elevated platform will offer a sweeping panoramic view of the massive 44-acre footprint of the K-25 Building, which once produced enriched uranium used in the weaponry that ended World War II.

The Nuclear Regulatory Commission noted two low-level regulatory violations during a recent inspection of the San Onofre Nuclear Generating Station, which is currently undergoing decommissioning in Southern California. The violations involved the shipment of two reactor pressurizers from San Onofre to EnergySolutions’ disposal facility in Clive, Utah.

A collaboration between Savannah River Nuclear Solutions (SRNS) and Savannah River National Laboratory (SRNL) is making progress toward processing non-aluminum spent nuclear fuel (NASNF) as part of the site’s accelerated basin de-inventory mission. SRNL is the managing and operating contractor at the Department of Energy’s Savannah River Site in South Carolina.

Savannah River Nuclear Solutions (SRNS), the management and operations contractor for the Department of Energy’s Savannah River Site, announced that it has injected more than 100 million gallons of clean artesian well water to neutralize shallow groundwater contamination underneath 33 acres of a former coal storage yard and the associated runoff basin at the site in South Carolina. According to Ashley Shull, senior scientist for the project, “100 million gallons is nine times more water than [is] contained in the Georgia Aquarium in Atlanta.”

The Department of Energy’s Office of Environmental Management has issued a final request for proposals for an infrastructure support services (ISS) contract at the department’s Paducah Site in Kentucky, which is the former home of the Paducah gaseous diffusion uranium enrichment plant. DOE-EM has conducted extensive cleanup and environmental remediation activities at the site since the late 1980s.

Sogin (Società Gestione Impianti Nucleari), the state-owned company responsible for the decommissioning of Italy’s nuclear plants and the management of radioactive waste, announced on July 30 that it has completed the first phase of dismantling Garigliano nuclear power plant’s reactor vessel with the removal of contaminated metal components from the deflector.

The Department of Energy has issued a request for information to gather input on its proposed package performance demonstration, which is intended to demonstrate the robustness of spent nuclear fuel transportation casks in hypothetical accident conditions. By simulating severe accident scenarios, the DOE said it intends to show to the public and stakeholders the safety and reliability of transporting SNF by rail, heavy-haul truck, and barge.

Workers at the Savannah River Site have recently completed the replacement of a piece of equipment that the Department of Energy said in a July 31 press release is “essential for operations in the site’s H Canyon chemical separations capable facility.”

Work crews have started retrieval of radioactive and chemical waste from a third set of underground storage tanks at the Hanford Site, according to the Department of Energy's Office of Environmental Management. Contractor Washington River Protection Solutions (WRPS) is retrieving and transferring more than 325,000 gallons of waste from the single-shell Tank A-101 at the site's A Tank Farm. The waste is being sent to a newer double-shell tank for continued safe storage.
Retrieval activities began one month after workers emptied the site’s 21st single-shell tank. Waste removed from the 21 tanks totals about 3 million gallons.

Despite efforts to increase hiring, the Department of Energy’s Office of Environmental Management continues to be understaffed, according to a recent Government Accountability Office report. The GAO found that, at the end of fiscal year 2023, DOE-EM had 263 vacant positions across its headquarters, cleanup sites, and EM Consolidated Business Center—a vacancy rate of 17 percent. The office is responsible for the cleanup of the environmental legacy waste resulting from decades of nuclear weapons production and government-sponsored nuclear energy research.

Oklo Inc. announced that it has completed the first end-to-end demonstration of its advanced fuel recycling process as part of an ongoing $5 million project in collaboration with Argonne and Idaho National Laboratories. Oklo’s goal: scaling up its fuel recycling capabilities to deploy a commercial-scale recycling facility that would increase advanced reactor fuel supplies and enhance fuel cost effectiveness for its planned sodium fast reactors.

The township of Ignace in northwestern Ontario has indicated its willingness to host a potential deep geologic repository for Canada’s spent nuclear fuel. The town council voted unanimously on July 10 to pass a resolution indicating its willingness to participate in the Nuclear Waste Management Organization’s (NWMO's) process for selecting a repository site, making it the first Canadian community to officially move forward with the next phase of a site selection process that began in 2010.
