Canada’s Nuclear Waste Management Organization (NWMO) is shifting the timing for selecting a preferred site for a spent nuclear fuel repository to the fall of 2024, a full year later than previously planned. The NWMO, a nonprofit organization tasked with the safe, long-term management of Canada’s spent fuel in a deep geological repository, said the delay is the result of several provincial lockdowns associated with the COVID-19 pandemic.

Washington River Protection Solutions (WRPS) is preparing to retrieve waste from Tank AX-101 at the Department of Energy’s Hanford Site near Richland, Wash. WRPS is the tank operations contractor at Hanford.

Deep Isolation announced that it has signed a memorandum of agreement with engineering services company Amentum to further the commercialization of Deep Isolation’s nuclear waste storage and disposal technology around the world. The initial targets for joint work include locations in Europe and the Pacific that represent a combined market for geologic disposal of spent fuel and high-level waste worth more than $30 billion, the company said.

The Department of Energy’s Office of Environmental Management (EM) celebrated the opening of a new exhibit at the National Atomic Testing Museum in Las Vegas during a ceremony on August 2.
Created through a partnership between EM and the museum, the permanent exhibit, “Beyond the Manhattan Project: Cleaning up the Legacy of America’s Nuclear Defense and Research Missions,” offers a visual display of EM’s critical work to clean up sites across the country impacted by five decades of nuclear weapons production and government-sponsored nuclear energy research.

The Government Accountability Office is recommending that Congress clarify the Department of Energy’s legal authority to sell depleted uranium hexafluoride (DUF6) left over from uranium enrichment operations at the department’s Portsmouth Site in Ohio and the Paducah Site in Kentucky.

Savannah River Mission Completion (SRMC), the radioactive liquid waste contractor at the Department of Energy’s Savannah River Site, is optimizing some equipment maintenance at the Salt Waste Processing Facility (SWPF). The facility traditionally uses centrifugal contactors in the solvent extraction process, and its laboratory uses manipulators to handle process samples and equipment within its radioactive cell. The equipment requires periodic maintenance and rebuilding.

Westinghouse Electric Company was awarded an engineering contract with Norsk Nukleær Dekommisjonering (NND) to plan the decommissioning of the country’s two nuclear research reactors, located in Halden and Kjeller. The three-year agreement includes options up to six years and is valued at up to $100 million (NOK 1 billion).

The Nuclear Regulatory Commission has published its final environmental impact statement (EIS) for Holtec International’s proposed HI-STORE consolidated interim storage facility (CISF) for spent nuclear fuel in southeastern New Mexico. Based on its environmental review, the NRC staff recommends issuing the license, subject to the findings in the staff’s ongoing safety review of the application.

The Department of Energy’s Office of Environmental Management (EM) said it continues to make progress toward the start of operations of the Idaho National Laboratory Site’s Integrated Waste Treatment Unit (IWTU), having completed a final test run of the facility.
Operation of the IWTU, which was constructed to treat approximately 900,000 gallons of radioactive liquid waste, has been delayed a number of times, most recently due to supply chain issues.
The Waste Isolation Pilot Plant in southeastern New Mexico.
Reston, Va.-based Tularosa Basin Range Services (TBRS), a single-purpose entity under the umbrella of Bechtel National, has been awarded the 10-year, $3 billion management and operating contract for the Waste Isolation Pilot Plant (WIPP) by the Department of Energy’s Office of Environmental Management (EM). Located near Carlsbad, N.M., WIPP is the DOE’s geologic repository for defense-generated transuranic waste.
The new contract replaces the current WIPP M&O contract held by Nuclear Waste Partnership, which expires on September 30. The contract with TBRS was announced on July 11.

The U.S. Supreme Court on June 21 struck down a Washington state workers’ compensation law that was designed to make it easier for workers at the Department of Energy’s Hanford Site to receive compensation benefits. The court, by unanimous decision, found that the law violates the U.S. Supremacy Clause and discriminates against the federal government and its contractors.
Located near Richland, Wash., the Hanford Site produced plutonium for the U.S. weapons program for more than 40 years and is currently undergoing a massive radiological cleanup mission involving around 10,000 workers.

Researchers at three Canadian universities are studying whether bentonite clay—used as an engineered barrier in Canada’s proposed deep geological repository—can support sulfide-producing microbes that can eat away at the canisters containing spent nuclear fuel.

Canada’s Nuclear Waste Management Organization (NWMO) has announced that it has successfully completed a full-scale demonstration of the engineered barriers that are designed to contain and isolate Canada’s spent nuclear fuel in a deep geological repository.

In this week’s “EM Update,” the Department of Energy’s Office of Environmental Management (EM) reports that its contractor Savannah River Nuclear Solutions (SRNS) has successfully reduced degreasing solvents in the aquifer beneath the Savannah River Site in South Carolina using a technology that injects a form of iron and oil into groundwater.
“The oil attracts the Cold War[–era] cleaning solvents while the iron degrades and neutralizes the contamination,” said Shannan Lucero, SRNS manager for area closure projects.
