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.

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.

The Department of Energy’s Office of Nuclear Energy has wrapped up testing of its Atlas railcar, successfully completing a round-trip journey from Pueblo, Colo., to Scoville, Idaho. Built to safety standards set by the Association of American Railroads (AAR), the 12-axle railcar is designed to transport large containers of spent nuclear fuel and high-level radioactive waste.

Per- and polyfluoroalkyl substances (PFAS), an anthropogenic class of several thousand chemicals made for use in products such as nonstick cookware, water-, grease-, and stain-resistant materials, surfactants, and fire suppression foams [1], are emerging as a complicating factor in nuclear decommissioning. These chemicals, which have been manufactured globally, including in the United States, have gained regulatory and public attention due to their persistence and ubiquity in the environment, ability to be detected at low parts-per-trillion levels, and health-based standards set at levels hundreds to thousands of times lower than more classic contaminants such as polychlorinated biphenyls (PCBs).

Washington state’s Department of Ecology said it has reached a settlement with the Department of Energy over access to data the state described as “critical” to the cleanup of the Hanford Site near Richland, Wash.

The Securities and Exchange Commission is suing nuclear battery developer NDB Inc., charging that the company and its chief executive officer, Nima Golsharifi, defrauded investors by making materially false and misleading statements in a company press release.

Workers at the Hanford Site’s Waste Treatment and Immobilization Plant, also known as the Vit Plant, have begun removing the first three of 18 temporary startup heaters, the Department of Energy announced on September 12. The startup heaters were used to raise the first of two 300-ton glass melters in the plant’s Low-Activity Waste Facility to its operating temperature of 2,100°F.

The Environmental Protection Agency announced last week that it is adding Oklahoma’s Fansteel Metals/FMRI Superfund site to the National Priorities List. The list includes the nation’s most serious uncontrolled or abandoned releases of contamination and serves as the basis for prioritizing EPA Superfund cleanup funding and enforcement actions.
