The Palisades nuclear power plant.
The Nuclear Regulatory Commission has made Holtec International’s post-shutdown decommissioning activities report (PSDAR) for the closed Palisades nuclear power plant available for public comment until December 27. The NRC also plans to hold a public meeting to discuss the report on the evening of September 22 at the South Haven campus of Lake Michigan College, about 10 miles north of the Palisades site in Covert, Mich.
The San Onofre nuclear power plant.
The San Onofre Nuclear Generating Station (SONGS) recently shared a few videos on its YouTube channel, showing recent progress Southern California Edison has made in dismantling the plant’s turbine building. Decommissioning of the nuclear power plant, which permanently ceased operations in 2013, is being conducted by SONGS Decommissioning Solutions, a joint venture of EnergySolutions and AECOM.

Westinghouse Electric Company was awarded an engineering contract with Norsk Nukleær Dekommisjonering (NND) to plan the decommissioning of the country’s two nuclear research reactors, located in Halden and Kjeller. The three-year agreement includes options up to six years and is valued at up to $100 million (NOK 1 billion).

Holtec International announced on June 28 that it has completed the acquisition of the Palisades nuclear power plant and the Big Rock Point site from Entergy Corporation. The Nuclear Regulatory Commission approved the license transfer for the two sites, both located in Michigan, in December 2021.

The Department of Energy’s Office of Environmental Management (EM) said that construction is well underway on a protective enclosure, or cocoon, for the K East Reactor building at the Hanford Site near Richland, Wash.
EM reports that is has achieved one of its key construction priorities for 2022 by beginning construction of the enclosure, which is designed to protect the reactor building while the radioactivity in the deactivated reactor core decays over the next several decades, making it safer and easier to decommission.
A time-lapse video showing the construction of the cocoon’s massive 120-foot steel frame can be seen here.

Dounreay Site Restoration Ltd. (DSRL) and the Robotics and Artificial Intelligence in Nuclear (RAIN) Hub, a consortium of universities led by the University of Manchester, are working together on the development of robots capable of accessing areas that are inaccessible or unsafe for humans to work in. The robots will be used to inspect and characterize Dounreay’s laboratories, buildings, and structures as the United Kingdom prepares to decontaminate and decommission the nuclear site.
The Kewaunee nuclear power plant in Carlton, Wis.
The Nuclear Regulatory Commission has approved the transfer of the operating license of the shutdown Kewaunee nuclear power plant from Dominion Energy to EnergySolutions. The transfer, which includes the general license for the Wisconsin site’s spent fuel storage facility, is contingent upon approval by the Wisconsin Public Service Commission.
EnergySolutions entered into an agreement with Dominion in May 2021 to acquire the Kewaunee site for decommissioning.

Depending on the size and complexity of a decommissioning project, the transportation and disposal of radioactive waste will have an oversized impact on planning, schedule, and budget. The scope of decommissioning a site contaminated with radioactive material begins and ends with the proper and safe packaging of waste and subsequent transportation from the site to the final disposal location. Once all of the waste is gone from the site, the compliance exercise can be completed and the site released from controls (i.e., the radioactive materials license is terminated and the site is decommissioned).

Utah-based EnergySolutions is joining Radiation Safety and Control Services (RSCS) in the decommissioning of NS Savannah, the world’s first nuclear-powered merchant ship, currently berthed at the Port of Baltimore in Maryland. EnergySolutions announced on March 29 that a joint venture of the two companies, Nuclear Ship Support Services, is conducting the final phases of decommissioning the ship’s reactor, which was defueled in 1975 but remains in place.

Holtec International and Hyundai Engineering & Construction have signed an agreement to cooperate in the area of nuclear plant decontamination and decommissioning.
Under the teaming agreement, Hyundai E&C will participate in D&D activities at Holtec-owned decommissioning sites in the United States to build its capabilities and experience in preparation for decommissioning projects in South Korea, which will be undertaken by the two companies. The agreement also provides for the two companies to further expand their cooperation internationally.

The Department of Energy’s Office of Environmental Management (EM) announced on February 10 that it is set to deactivate and demolish the prototype for the reactor used for the USS Nautilus, the world’s first operational nuclear-powered submarine and the first submarine to complete a submerged transit of the North Pole.
The Palisades power plant, in Covert Township, Mich.
The Nuclear Regulatory Commission has approved the transfer of the Palisades nuclear power plant licenses from Entergy Nuclear Operations to Holtec International, as owner, and Holtec Decommissioning International (HDI), as decommissioning operator. Holtec and HDI intend to decommission the single-unit pressurized water reactor, located in Covert, Mich., under an accelerated schedule.
