A nearly yearlong effort to de-tension and remove more than 400 steel cables, known as tendons, from the two containment domes of the San Onofre Nuclear Generating Station (SONGS) was recently completed, with only one minor first aid incident recorded, according to Southern California Edison.

Over the past decade, the Department of Energy has been collecting data on nuclear power plants to help plan for the eventual removal of spent nuclear fuel from the sites, performing site evaluations to assess transportation infrastructure and the transportability of spent fuel.

Orano has delivered its first TN-LC spent nuclear fuel transport cask to Korea Hydro and Nuclear Power Company. The first use of the cask is planned for an international transport between South Korea and Sweden by the end of 2021.
KHNP received a license in June for the TN-LC transport cask from the Nuclear Safety and Security Commission, South Korea’s regulatory agency, for the transport of high-burnup spent fuel.

Westinghouse will segment and dispose of the reactor internals and pressure vessels at Sweden’s Ringhals-1 and Ringhals-2 under a deal announced last week with plant owner Vattenfall. Unit 2, a pressurized water reactor, and Unit 1, a boiling water reactor, were shut down in 2019 and 2020, respectively, after operating for more than 40 years.

The Department of Energy is celebrating a major milestone in its tank waste mission at the Hanford Site near Richland, Wash. DOE tank operations contractor Washington River Protection Solutions has finished construction of the pipeline that will carry treated waste from an underground tank to the Waste Treatment and Immobilization Plant (WTP) for vitrification.

While it has been known for decades that bacteria known as Geobacter could clean up uranium waste, researchers at Michigan State University recently uncovered the biological mechanism behind the bacteria’s ability to do it.

DGR Grant Construction will construct a safe-storage enclosure over the K East Reactor building at the Department of Energy’s Hanford Site in Washington state. Two construction subcontracts, worth about $9.5 million, were awarded to the Richland, Wash.–based company by Central Plateau Cleanup Company, the DOE’s Richland Operations Office site cleanup contractor.

The Nuclear Regulatory Commission has issued its final environmental impact statement on an application by Interim Storage Partners for a license to construct and operate a consolidated interim storage facility for spent nuclear fuel in Andrews County, Texas. After considering the environmental impacts of the proposed action, the NRC announced today that its staff has recommended granting the proposed license.

Nuclear waste should not be used as an excuse for trying to shut down nuclear reactors, says radiation safety expert Andrew Karam in his recent article for the American Council on Science and Health titled, “Let’s Talk about Radioactive Waste."
The DOE recently completed startup testing on the uninterruptable electrical power system for Hanford’s Low-Activity Waste Facility.
Department of Energy workers recently finished startup testing of a battery-powered backup electrical system for the Low-Activity Waste (LAW) Facility at the Hanford Site near Richland, Wash. According to the DOE’s Office of Environmental Management (EM), the uninterruptable electrical power system is vital to safeguarding the facility, part of Hanford’s Waste Treatment and Immobilization Plant, in the unlikely event of a temporary power loss to the plant.

The Department of Energy's Office of River Protection and the Richland Operations Office hosted a roundtable discussion recently with tribal nations located near the Hanford Site to review the Department’s tribal government policy—Order 144.1, the American Indian and Alaska Native Tribal Government Policy—and discuss opportunities for strengthening tribal consultation.
The Office of River Protection is within the purview of the DOE's Office of Environmental Management (EM). The Hanford Site, in eastern Washington state, is a 586-square-mile site that was used as a nuclear production complex during the World War II era.

The Defense Nuclear Facility Safety Board, which provides independent federal oversight of Department of Energy weapons facilities, has reported that low-level radioactive and other combustible waste is accumulating in the basement of Los Alamos National Laboratory’s Plutonium Facility (PF-4), and that housekeeping and waste management in the PF-4 basement have been a continuing challenge.
