The Nuclear Regulatory Commission has updated its guidance for nuclear power plant owners and operators in estimating the cost of decommissioning their reactors. Licensed power reactor operators are required under NRC regulations to annually adjust the estimated costs (in current year U.S. dollars) of decommissioning their plants to ensure that adequate funds are available when needed.

The Department of Energy’s Office of Environmental Management said it has reached a regulatory milestone ahead of schedule in preparing radioactive waste tanks for closure at the Savannah River Site in South Carolina. DOE-EM said it received concurrence in January from the South Carolina Department of Environmental Services (SCDES) and the U.S. Environmental Protection Agency that SRS had successfully removed waste from the site’s Tank 4 and may now proceed to waste sampling and analysis of that tank ahead of its closure.

Germany’s NUKEM Technologies Engineering Services GmbH, in partnership with Uniper Nuclear Services GmbH (UNS), has successfully completed the dismantling of the fourth and final reactor pressure vessel (RPV) at Oskarshamn nuclear power plant in Sweden. The work was done as part of the UNNU Consortium, which since 2020 has been dismantling Sweden’s four RPVs—two at the Oskarshamn site and two at the Barsebäck nuclear plant site.

The U.K. government’s Nuclear Waste Services said it has identified three “areas of focus” in its search to find a suitable site and a willing community to host a geologic disposal facility (GDF) for the country’s most hazardous radioactive waste. The areas are within three communities currently involved in the siting process—Mid Copeland and South Copeland in Cumbria, and East Lincolnshire, England.
