The Department of Energy’s Office of Environmental Management said that crews at the Idaho National Laboratory site are making “significant progress” decommissioning the Submarine 1st Generation Westinghouse (S1W) reactor, the prototype pressurized water reactor that supported the development of the USS Nautilus, the world’s first operational nuclear-powered submarine.

The Department of Energy has released two additional requests for information related to its Cleanup to Clean Energy initiative, which aims to repurpose certain DOE-owned lands—portions of which were previously used during the nation’s nuclear weapons program—into sites for clean energy generation, including include solar, geothermal, wind, and nuclear electricity.

The Department of Energy’s Office of Environmental Management said a new regulatory partnership framework established in recent years by the Oak Ridge Office of Environmental Management (OREM), its contractor United Cleanup Oak Ridge (UCOR), the Environmental Protection Agency, and the Tennessee Department of Environment and Conservation (TDEC) is ushering in a new chapter of accelerated cleanup at the department’s Oak Ridge Reservation in Tennessee.

The Department of Energy’s Office of Environmental Management, which is responsible for the cleanup of 15 nuclear sites across the country, lacks a clear understanding of its costs for work not directly related to site cleanup, hampering the department’s ability to prioritize competing funding needs, according to a report by the Government Accountability Office.

The Department of Energy’s Office of Environmental Management announced it has completed a second of its 2023 priorities at Oak Ridge in as many months with the demolition of the Low Intensity Test Reactor, known as Building 3005, at the Tennessee site.

The Department of Energy’s Office of Environmental Management has awarded nearly $54 million in noncompetitive financial assistance grants and cooperative agreements to help support the office’s cleanup program. DOE-EM is responsible for environmental legacy cleanup of the effects of decades of nuclear weapons development and government-sponsored nuclear energy research.

The Department of Energy’s Office of Environmental Management has issued a draft request for proposal for a contract covering the next phase of cleanup at the West Valley Demonstration Project in western New York.

The Department of Energy has released the first request for information (RFI) related to the department’s Cleanup to Clean Energy initiative, which aims to repurpose certain DOE-owned lands, portions of which were previously used in the nation’s nuclear weapons program, into sites for clean energy generation.

Robotics experts from Sandia National Laboratories and representatives from the Department of Energy Office of Environmental Management’s Technology Development Office recently visited the Sellafield nuclear site in England to discuss how robotics, artificial intelligence, and other emerging tools can be developed and used in nuclear cleanup operations.

The Department of Energy’s Office of Environmental Management said that crews have completed major deactivation efforts at the Alpha-2 building at the Y-12 National Security Complex in Oak Ridge, Tenn. The former uranium enrichment facility is scheduled for demolition next year.

The Department of Energy’s Office of Environmental Management announced that the first batches of glass-forming beads, called frit, were poured last week into a melter at the Hanford Site’s Waste Treatment and Immobilization Plant (WTP), also known as the Vit Plant. The melter, which has been heated to 2,100ºF, will be used to immobilize Hanford’s radioactive and chemical tank waste, turning it into a stable glass form through vitrification.

The Idaho National Laboratory is moving closer toward closing its largest building—which, at more than 316,000 square feet, could comfortably house a modern U.S. aircraft carrier, according to the Department of Energy.

The Department of Energy’s Office of Environmental Management awarded a contract to Aptim Federal Services of Baton Rouge, La., to perform deactivation, decommissioning, and removal of the former Ion Beam Facility at Los Alamos National Laboratory in New Mexico.

A three-day Minority Serving Institutions Partnership Program (MSIPP) event, led by Savannah River National Laboratory researcher Simona Hunyadi Murph, was held recently at the South Carolina site, according to a release by the Department of Energy’s Office of Environmental Management (DOE-EM). The event included a collaborative workshop, job shadowing, and a tour of the laboratory and Savannah River Site field activities.

The Department of Energy’s Office of Environmental Management awarded a 10-year contract worth up to $5.87 billion to Southern Ohio Cleanup Company (SOCCo) of Aiken, S.C., for the decontamination and decommissioning of the DOE’s Portsmouth site in southern Ohio. SOCCo is a newly formed limited liability company comprising Amentum Environment and Energy, Fluor Federal Services, and Cavendish Nuclear (USA) Inc.

The Department of Energy has awarded an estimated $2.6 million to the National Governors Association (NGA) Center for Best Practices to work collaboratively with governors to solve the continued challenges posed by waste management and cleanup at DOE sites, the DOE’s Office of Environmental Management announced on July 5.

The Department of Energy’s Office of Environmental Management recently shipped for off-site disposal 14 sodium fluoride traps, or exchange vessels, from the C-310 Product Withdrawal facility at the DOE’s Paducah Gaseous Diffusion Plant site in Kentucky. DOE-EM said it has also eliminated the site’s entire inventory of chlorine gas cylinders.

The Department of Energy’s Office of Environmental Management and the New Mexico Environment Department (NMED) have negotiated a settlement on terms to renew the 10-year operating permit for the Waste Isolation Pilot Plant near Carlsbad, N.M. The DOE, along with WIPP’s operating contractor, Salado Isolation Mining Contractors, and the NMED negotiated the settlement with New Mexico stakeholders.

The Department of Energy’s Office of Environmental Management has awarded a $2 million grant to the Paducah Area Chamber of Commerce for its work in considering the possible future uses of the Paducah Gaseous Diffusion Plant site in Kentucky. The project will consist of site mapping, community studies, data analysis, and development of recommended strategies.
