Researchers at Savannah River National Laboratory (SRNL), in concert with Lawrence Berkeley National Laboratory, Massachusetts Institute of Technology, Pacific Northwest National Laboratory, and Florida International University, are leading the Advanced Long-Term Environmental Monitoring Systems (ALTEMIS) project to move groundwater cleanup from a reactive process to a proactive process, while also reducing the cost of long-term monitoring and accelerating site closure.

It is the 1940s in Maywood, N.J. A new residential community has sprouted up, and the homeowners want to beautify their front lawns, so they go to a nearby property to gather some fresh topsoil. Little did they know that they’re helping to plant the seeds for one of the largest and most high-profile environmental cleanup projects in the nation.

Currently, the Nuclear Regulatory Commission is overseeing 17 nuclear power plants that are undergoing active decommissioning. For 10 of those plants, the NRC licenses have been transferred, either through sale or temporary transfer, from the plant owner and operator to a third party, nonutility company for decommissioning. To be profitable, those companies are decommissioning the nuclear plants as expediently as they safely can, while still protecting workers and the environment, using proprietary techniques and processes.

Baton Rouge, La.-based Aptim Federal Services announced that the U.S. Army Corps of Engineers, Baltimore District, has awarded the company a six-year, $95.5 million contract to decommission, dismantle, and dispose of the SM-1A nuclear power reactor at Fort Greely, Alaska.
Josh Everett, a diver with UCC UK Ltd., enters bay No. 11 of Sellafield’s Pile Fuel Storage Pond in December 2022, the first time in over 60 years a diver has entered the legacy pond, used to store a variety of spent nuclear fuel types and wastes. During this commissioning nuclear dive, Everett’s underwater tasks included emergency diver extraction trial confirmation, radiation monitoring system verification, and radiation contact meter commissioning.

The last time a human entered the Pile Fuel Storage Pond at the Sellafield nuclear site in Cumbria, England, was in 1958, when records show a maintenance operator and health physics monitor carried out a dive into the newly constructed pond to repair a broken winch. At least that was true until December 2022, when Josh Everett, a diver from the U.K. specialist nuclear diving team Underwater Construction Corporation (UCC) UK Ltd., became the first person in more than 60 years to work in one of the most unique workplaces in the world.

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 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.
