All four steam generators at Germany’s Unterweser nuclear power plant have been removed from the reactor building, plant owner PreussenElektra has announced. The single-unit pressurized water reactor was shut down in 2011 as part of Germany’s decision to phase out nuclear energy. Decommissioning and dismantlement of the reactor began soon after PreussenElektra was granted a permit for the work in February 2018.

A scientific mission led by the French National Centre for Scientific Research (CNRS) set sail this past weekend in the Northeast Atlantic to investigate the long-term impacts of radioactive waste dumped at sea between the 1950s and 1990s.

Working with the Environmental Protection Agency, the Department of Energy has revised its planned approach to remediating contaminated soil underneath the Chemical Materials Engineering Laboratory (commonly known as the 324 Building) at the Hanford Site in Washington state. The soil, which has been designated the 300-296 waste site, became contaminated as the result of a spill of highly radioactive material in the mid-1980s.

A new method has received Washington state’s approval for use at the 222-S Laboratory at the Department of Energy’s Hanford Site, improving how experts analyze tank waste and providing more precise data to support safe and efficient cleanup.

The Nuclear Waste Management Organization, which is mandated by law to develop an approach for the long-term care of Canada’s spent nuclear fuel, has begun collecting feedback from Canadians and Indigenous people to help refine its process for selecting a second deep geologic repository site.
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.
Cleanup crews successfully removed the defueled reactor vessel from the Submarine 1st Generation Westinghouse naval nuclear propulsion prototype reactor plant. (Photo: DOE)
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.
Simulator instructor Marc Widener at the controls of a new crane simulator for the Savannah River Site’s Defense Waste Processing Facility.
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.
