The Department of Energy’s Office of Environmental Management said that crews with the Oak Ridge Office of Environmental Management (OREM) and its cleanup contractor UCOR are preparing to demolish another deteriorating Manhattan Project–era building at the Y-12 National Security Complex at Oak Ridge, Tenn.
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.
Sellafield Ltd. and AtkinsRéalis have successfully operated a robotic dog from a remote location in what might be the first time such an operation has happened at a nuclear licensed site, according to the companies in a March 18 press release.
NorthStar Group Services has announced that it has closed on an agreement to acquire ownership of the Vallecitos Nuclear Center from GE Vernova and GE Hitachi Nuclear Energy for NorthStar's nuclear decontamination, decommissioning, and environmental site restoration.
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.
Work has started at the Department of Energy’s Los Alamos National Laboratory in New Mexico to deactivate, decommission, and remove the Ion Beam Facility, which played a role in research and experiments that helped develop the nation’s nuclear arsenal during the 1950s and 1960s.
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.
