The USS Enterprise is to be dismantled in Mobile, Ala.
The U.S. Department of Defense has awarded NorthStar Group Services subsidiary NorthStar Maritime Dismantlement Services a firm-fixed-price contract worth $536,749,731 for the dismantling, recycling, and disposal of the historic USS Enterprise (now also known as the ex-Enterprise), the world’s first nuclear-powered aircraft carrier. The work will be performed in Mobile, Ala., and is expected to be completed by November 2029.

Tokyo Electric Power Company has released the results of its initial analysis of a sample of nuclear fuel debris from Unit 2 of Japan’s damaged Fukushima Daiichi nuclear power plant. The sample, which measured around 5mm by 4mm and totaled 0.187 grams, was taken from the floor of the reactor pedestal during a second trial removal of fuel debris conducted in April.

A milestone was reached by Idaho Cleanup Project crews in the deactivation and demolition of the defueled Submarine 1st Generation Westinghouse (S1W) naval nuclear propulsion prototype reactor plant, which had once served as a training ground for about 14,000 U.S. Navy submariners and plant operators.
Workers offload nitrogen into the LAW Facility at Hanford’s Waste Treatment and Immobilization Plant. The nitrogen, mixed with other materials, will simulate tank waste as the facility prepares for waste operations later this year. (Photo: DOE)
The Department of Energy’s Office of Environmental Management announced that it has introduced waste simulant chemicals to the Hanford Site’s Waste Treatment and Immobilization Plant (WTP) as part of the cold commissioning testing of the plant’s Low-Activity Waste Facility.

A milestone has been reached at the Department of Energy’s Paducah Site when work crews successfully fabricated valves from old equipment and installed them on 137 specialized cylinders. This action will enable future work crews to transform depleted uranium hexafluoride (DUF6) stored inside the cylinders into depleted uranium oxide, a stable chemical form suitable for reuse, storage or disposal.

The Department of Energy’s Oak Ridge Office of Environmental Management recently completed the transfer of a 32-acre parcel at the East Tennessee Technology Park (ETTP) for private sector use. The transfer brings the total amount of property transferred from federal ownership for economic reuse to 1,832 acres at the ETTP, which was once home to the Oak Ridge Gaseous Diffusion Plant.

The Department of Energy’s Office of Environmental Management said it will use a new simulator to help train operators on the safe and efficient movement of a remotely operated crane at the Defense Waste Processing Facility (DWPF) at the Savannah River Site in South Carolina. The DWPF, where Savannah River’s liquid high-level radioactive waste is vitrified and placed into storage containers, uses an unmanned bridge crane system to install and replace equipment in the high-humidity, high-radiation, and harsh chemical environment of the facility’s processing cells.

Canada’s Nuclear Waste Management Organization has selected five companies it is to work with to design and plan the organization’s proposed deep geologic repository for spent nuclear fuel. As the owner of the project, the NWMO will be working with WSP Canada, Peter Kiewit Sons (Kiewit), Hatch Ltd., Thyssen Mining Construction of Canada, and Kinectrics.

As part of its Test Bed Initiative (TBI) demonstration project, the Department of Energy’s Office of Environmental Management completed two shipments of treated, low-activity tank waste from the Hanford Site near Richland, Wash. The approximately 2,000 gallons of TBI waste will be solidified in grout and permanently disposed of at Waste Control Specialists’ (WCS) federal disposal facility in Andrews County, Texas, and at EnergySolutions’ disposal facility in Clive, Utah.

A 1960s Electrolux vacuum cleaner was among the more unusual items workers removed from one of the world’s oldest nuclear waste stores at the United Kingdom’s Sellafield nuclear site.

An agreement signed by the state of Idaho and the U.S. Department of Energy will open the way for a single cask of high-burnup spent nuclear fuel to be shipped from Dominion Energy’s North Anna nuclear power plant in Virgina to Idaho National Laboratory for research purposes.

Nuclear energy produces about 9 percent of the world’s electricity and 19 percent of the electricity in the United States, which has 94 operating commercial nuclear reactors with a capacity of just under 97 gigawatts-electric. Each reactor replaces a portion of its nuclear fuel every 18 to 24 months. Once removed from the reactor, this spent (or used) nuclear fuel (SNF or UNF) is stored in a spent fuel pool (SFP) for a few years then transferred to dry storage.
An international team of researchers have collaborated to reduce operational risk and realize a vision of long-term success for the Waste Treatment and Immobilization Plant (WTP) at the Department of Energy’s Hanford Site near Richland, Wash.

For over a decade, the DOE’s Hanford Field Office (HFO) has been working with national laboratories, universities, and glass industry experts to establish capabilities and generate data to increase the confidence in a successful startup and transition to full-time operations at the WTP.

The cost to complete the cleanup of the Department of Energy’s Hanford Site in Washington state could cost as much as $589.4 billion, according to the 2025 Hanford Lifecycle Scope, Schedule, and Cost Report, which was released by the DOE on April 15. While that estimate is $44.2 billion lower than the DOE’s 2022 estimate of $640.6 billion, a separate, low-end estimate has since grown by more than 21 percent, to $364 billion.
The life cycle report, which the DOE is legally required to issue every three years under agreement with the U.S. Environmental Protection Agency and Washington State Department of Ecology (Ecology), summarizes the remaining work scope, schedule, and cost estimates for the nuclear site. For more than 40 years, Hanford’s reactors produced plutonium for America’s defense program.

The Optimized Segmentation process patented by Orano Decommissioning Services was successfully implemented for the first time at the Crystal River Unit 3 (CR-3) decommissioning project in Florida [1]. Using this approach, Orano was able to avoid the time- and resource-intensive process of packaging components into numerous standardized waste containers and significantly reduced the required segmentation activities.
