The Department of Energy has extended Savannah River Nuclear Solutions’ (SRNS) management and operating contract at the Savannah River Site (SRS) in South Carolina for up to an additional five years. The announcement was made recently 29 by engineering company Fluor, which leads the SRNS joint venture, along with Newport News Nuclear and Honeywell.

Based on a review of U.S. Atomic Energy Commission (AEC) records and available data from numerous agencies, there are an estimated 4,225 mines across the country that provided uranium ore to the U.S. government for defense-related purposes between 1947 and 1970. To aid in the cleanup of these legacy uranium mines and establish a record of their locations and current conditions, the Defense-Related Uranium Mines (DRUM) program was established within the Department of Energy’s Office of Legacy Management (LM).
ANS Standards Committee publishes new standard for light water reactor risk-informed, performance-based design
The new standard ANSI/ANS-30.3-2022, Light Water Reactor Risk-Informed, Performance-Based Design, has just been issued by the American Nuclear Society. Approved by the American National Standards Institute (ANSI) on July 21, 2022, the standard provides requirements for the incorporation of risk-informed, performance-based (RIPB) principles and methods into the nuclear safety design of commercial light water reactors. The process described in this standard establishes a minimum set of process requirements the designer must follow in order to meet the intent of this standard and appropriately combine deterministic, probabilistic, and performance-based methods during design development.

The Department of Energy announced up to $50 million for a new milestone-based fusion energy development program on September 22. The funding opportunity announcement is open to for-profit companies—possibly teamed with national laboratories, universities, and others—that are prepared to meet major technical and commercialization milestones leading to a pilot fusion power plant design.

This spring, the U.S. Government Accountability Office (GAO) released an insightful report reviewing and summarizing the status and performance of the largest projects and operations within the Department of Energy’s Office of Environmental Management (EM), which is responsible for the cleanup of hazardous and radioactive waste at sites and facilities that have been contaminated from decades of nuclear weapons production and nuclear energy research.

Nuclear power generation surpassed coal generation in the United States for the first time in 2020. As utilities continue to retire coal-fired plants, reusing the shuttered sites to host nuclear reactors could help the nation reach the goal of net-zero emissions by 2050 and prove economically beneficial both for nuclear deployments and for the communities impacted by fossil fuel generation. That’s according to a Department of Energy report released this week, detailing how hundreds of U.S. coal power plant sites that have recently retired or plan to close within the decade could be suitable for new nuclear power plants. Nuclear power’s high capacity factors mean those plants could deliver an added benefit—delivering more baseload power to the grid from the nameplate capacity replacement.
Demolition has begun on the Bulk Shielding Reactor at the Oak Ridge National Laboratory. It marks the first teardown of a former reactor at the site. (Photo: DOE).
In a first for the Department of Energy’s Oak Ridge Site, a former reactor facility is being demolished. The site’s cleanup contractor, UCOR, began tearing down the Bulk Shielding Reactor, also known as Building 3010, last week.
“While this project is not the biggest demolition we’ve undertaken, it carries a lot of significance,” said Laura Wilkerson, acting manager for the Oak Ridge Office of the DOE’s Office of Environmental Management (EM). “It is the first removal of a former reactor at [Oak Ridge National Laboratory], and it is a signal of much more to come at the site in the immediate future.”

Scientists in the Departments of Radiation Oncology and Medicine at the University of Washington (UW) and Fred Hutchinson Cancer Center (Fred Hutch) are directly targeting cancerous cells traveling through patients’ bloodstreams with diseases such as leukemia and lymphoma using an intravenous injection of the radioactive isotope astatine-211 (At-211). The work, its challenges, and its promise were described in a recent news release from the National Isotope Development Center (NIDC), which is managed by the Department of Energy’s Isotope Program.

Those who welcomed the $700 million earmarked for high-assay low-enriched uranium (HALEU) supply in the Inflation Reduction Act of 2022 (IRA) in August have cause to celebrate again. The White House sent a supplemental appropriation request to Congress on September 2 that would provide more than double the IRA funds if passed—$1.5 billion—for the Department of Energy’s Office of Nuclear Energy to build a reliable supply of both low-enriched uranium for existing U.S. nuclear power plants and HALEU for the advanced reactors that will be built within the decade.

Work is nearing completion on a fourth basin needed to ensure adequate storage for wastewater during tank waste treatment on the Department of Energy’s Hanford Site, in Washington state.
According to the DOE, its operations contractor Washington River Protection Solutions (WRPS) has made significant progress on Basin 41 at the Liquid Effluent Retention Facility (LERF) since concrete was first poured for the perimeter one year ago.

While many Californians are hopeful the state’s last nuclear power reactor can be saved, PG&E is actively preparing for decommissioning.

The reports of the death of the Diablo Canyon nuclear power plant may be greatly exaggerated. While Pacific Gas and Electric (PG&E) announced as early as 2016 that it would be closing California’s last operating nuclear power plant at the end of its current operating license, there has been growing political pressure to keep the plant, and its 2,200 MWe of carbon-free energy, running.
