The Department of Energy’s Office of Environmental Management awarded a 10-year contract worth up to $630 million to Louisiana-based Aptim Federal Services for deactivation and decommissioning work at two U.S. Naval Nuclear Propulsion Program sites in New York.

The Department of Energy’s Office of Environmental Management announced that it has completed construction of the new large-scale ventilation system at its Waste Isolation Pilot Plant in New Mexico.

The American Nuclear Society brought together 11 other energy and environmental advocacy organizations in calling on Congress to fund the Environmental Protection Agency to develop a new, technology-neutral, generic environmental standard for the disposal of spent nuclear fuel and high-level radioactive waste in the United States.

In a letter to the leaders of the House and Senate appropriations committees, the groups ask for an additional $3 million in fiscal year 2025 for the EPA’s Office of Radiation and Indoor Air to work on the new standard.

The staff of the Nuclear Regulatory Commission have sent a proposed rule covering the disposal of low-level radioactive waste to the agency’s commissioners for approval. The proposed rule would amend NRC regulations to require new and revised site-specific technical analyses and permit the development of site-specific criteria for LLW disposal. It would also authorize the near-surface disposal of certain greater-than-Class-C (GTCC) waste streams and provide for the licensing of those waste streams by NRC Agreement States.

Interim Storage Partners (ISP), a joint venture of Waste Control Specialists and Orano USA, has petitioned the U.S. Supreme Court to overturn the decision by the 5th Circuit Court of Appeals to vacate its license for a consolidated interim storage facility for commercial spent nuclear fuel in Andrews County, Texas.

With the placement of 25 wall sections, 208 support columns, and 7 roof sections, work crews have completed all major concrete placements for the megavolume Saltstone Disposal Unit (SDU) 10 at the Savannah River Site in South Carolina, according to the Department of Energy’s Office of Environmental Management.

The Department of Energy’s Office of Environmental Management and its contractor Washington River Protection Solutions (WRPS) recently demonstrated the use of cold spray technology as a means of refurbishing double-shell waste tanks at the Hanford Site in Washington state. The tanks store liquid radioactive and chemical waste that was created during Hanford’s plutonium production era.

The Department of Energy’s Office of Nuclear Energy announced last week that the Association of American Railroads has certified its Atlas railcar system to operate on all major freight railroads in the United States.

Watch a video of the Atlas railcar development here.

The Department of Energy will enter into lease negotiations with two solar energy developers for 400 megawatts of solar electricity generation within the Idaho National Laboratory site. Announced on June 5, the projects are the first proposed projects selected under the department’s Cleanup to Clean Energy initiative, an effort to repurpose parts of DOE-owned lands—portions of which were previously used in the nation’s nuclear weapons program—into sites of clean-energy generation, including for solar, geothermal, wind, and nuclear.

Switzerland’s national cooperative for the disposal of radioactive waste, Nagra, is distancing itself from recent reports regarding the work of the Geneva-based engineering start-up Transmutex, which claims to have developed a new technology for the transmutation of radioactive waste.
