Advanced reactor developer Terrestrial Energy and Utah-based waste management company EnergySolutions announced they have signed a memorandum of understanding to collaborate on the siting and deployment of Terrestrial Energy’s integral molten salt reactor plants at EnergySolutions-owned sites.
Veolia UK announced that it has developed a new method for salvaging copper from electrical cables from decommissioned nuclear facilities. The process, which handles and disposes of the contaminated plastic coating that protects the core from radiation, reduces the time and cost of treating the waste while preserving the copper for recycling, the waste management company said.
It’s safe to say that readers of Nuclear News are familiar with decommissioning. It’s even safe to assume that experienced decommissioning practitioners are familiar with the National Historic Preservation Act (NHPA) and how it applies to typical projects. What’s different about the N.S. Savannah is that the entire project site is a historic property—and in fact, is a federally owned National Historic Landmark (NHL), a status that confers the highest level of protection under law. Federal owners of NHLs are obligated to minimize harm in both planning and actions. Distilled to its salient point, no federal owner of an NHL should destroy it if there’s a reasonable alternative. That level of preservation is not what we normally associate with nuclear decommissioning. This perfectly summarizes the challenges, and opportunities, that decommissioning Savannah offered. The story of how the Maritime Administration (MARAD) managed these two otherwise contradictory processes showcases how historic preservation and decommissioning can positively intersect, provides a pathway for other historic facilities, and further adds to the already illustrious history of one of our nation’s significant 20th century landmarks.
The Department of Energy’s Office of Environmental Management announced it has awarded a 10-year, $3 billion contract to West Valley Cleanup Alliance (WVCA) for decommissioning and demolition work at the West Valley Demonstration Project in western New York. WVCA is a newly formed limited liability company made up of BWXT Technical Services Group, Jacobs Technology, and Geosyntec Consultant. Teaming subcontractors include Perma-Fix Environmental Services and North Wind Portage.
The pursuit of returning two of the country’s retired nuclear plants into service is not only unusual—it is unprecedented and promises to make history.
That’s according to a piece coauthored by former assistant secretary for nuclear energy Katy Huff in the Bulletin of the Atomic Scientists regarding plans from Holtec and Constellation to restart Michigan’s Palisades plant and Pennsylvania’s Three Mile Island Unit 1, respectively.
Chantilly, Va.-based Amentum has been awarded a 7-year contract estimated to be worth €5.5 million (about $6 million) to consult on the dismantling of steam drum separators in Units 1 and 2 of Lithuania’s Ignalina nuclear power plant. Once the country’s largest generator of electricity, Ignalina was permanently shut down in 2009 and the plant’s two RBMK-1500 reactors are expected to be fully decommissioned by 2038.
Despite progress made over the past years, the United Kingdom’s Nuclear Decommissioning Authority (NDA) has not seen an adequate return on investment in cleaning up the Sellafield nuclear site on England’s Cumbria coast, according to a new report by the U.K.’s National Audit Office, which scrutinizes government spending.
Orano USA announced that it has recently completed the transportation and disposal of the dismantled Crystal River Unit 3 reactor using only four large packages, which were shipped more than 1,800 miles each by barge and multi-axle trailer from the nuclear power reactor’s site on Florida’s west coast to Waste Control Specialists’ disposal facility in Andrews County, Texas.
Decommissioning begins on the closed Wisconsin power plant
In October 2012, Dominion Energy announced it was closing the Kewaunee nuclear power plant, a two-loop 574-MWe pressurized water reactor located about 27 miles southeast of Green Bay, Wis., on the western shore of Lake Michigan. At the time, Dominion said the plant was running well, but that low wholesale electricity prices in the region made it uneconomical to continue operation of the single-unit merchant power plant.
The Nuclear Regulatory Commission is soliciting public comment on the agency’s guidance for addressing discrete radioactive particle (DRP) contamination resulting from the decontamination and decommissioning of nuclear facilities. According to the NRC, the draft guidance is intended to avoid any inconsistencies in how the agency approaches DRP contamination.
The Pennsylvania Department of Environmental Protection (DEP) expressed its confidence in the decommissioning work taking place at the damaged Three Mile Island Unit 2 during a recent meeting of the TMI-2 Community Advisory Panel (CAP). “We cannot be more pleased with the progress being made,” said Dwight Shearer, director of the DEP, during the meeting, held on September 13 in Middleton, Pa.
The Nuclear Decommissioning Authority (NDA), the government agency charged with cleaning up the United Kingdom’s nuclear sites, has awarded three contracts totaling £30 million (about $39 million) for research into new decommissioning techniques.
The Nuclear Regulatory Commission noted two low-level regulatory violations during a recent inspection of the San Onofre Nuclear Generating Station, which is currently undergoing decommissioning in Southern California. The violations involved the shipment of two reactor pressurizers from San Onofre to EnergySolutions’ disposal facility in Clive, Utah.
The Department of Energy’s Office of Environmental Management awarded a 10-year contract worth up to $630 million to Louisiana-based Aptim Federal Services for deactivation and decommissioning work at two U.S. Naval Nuclear Propulsion Program sites in New York.
The Department of Energy’s Office of Environmental Management announced that the 30-foot-long, 37,600-pound reactor vessel from Oak Ridge National Laboratory’s Low Intensity Test Reactor was shipped to EnergySolutions’ low-level radioactive waste facility in Clive, Utah, in late April.
By an order dated April 25, the Nuclear Regulatory Commission has approved the transfer of ownership of Vallecitos Nuclear Center from GE Hitachi Nuclear Energy to NorthStar Group Services for nuclear decontamination, decommissioning, and environmental site restoration.
The Environmental Protection Agency recently announced that it will issue a rule aimed at limiting public exposure to per- and polyfluoroalkyl substances (PFAS). The final rule will designate two widely used PFAS chemicals, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as Superfund.
According to the EPA, both PFOA and PFOS meet the statutory criteria for designation as hazardous substances.
Registration is open for Argonne National Laboratory’s Facility Decommissioning Training Course, a four-day instruction designed for those responsible for the decontamination and decommissioning of nuclear facilities and who are looking to understand the full breadth and depth of the D&D processes.
The next session will be held July 16–19 in Santa Fe, N.M. Information on the course and how to register can be found here.
The Nuclear Regulatory Commission will hold a public meeting on May 8 to discuss the license termination process for the retired nuclear-powered merchant ship, the NS Savannah. During the meeting, NRC staff will discuss the license termination process and receive public comments on the remaining cleanup activities described in the license termination plan for the historic ship, which may see a second life as a floating museum.
The development of nuclear power is one of the pillars of Poland’s energy transition, which involves construction of safe and modern Generation III+ pressurized water reactors.
Polskie Elektrownie Ja˛drowe (PEJ) is the company responsible for, among other things, preparing the investment process for the construction of the first Polish nuclear power plant with a capacity of up to 3,750 MWe. PEJ’s goal is to build six nuclear reactors (for a total capacity of 6–9 GWe), securing 25 percent of the electricity needed in Poland by 2043 and guaranteeing a stable supply of clean energy to millions of homes across the country.
