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 Department of Energy’s Office of Environmental Management said that contractors have completed the treatment of 2,000 gallons of radioactive and chemical waste as part of the Hanford Site’s Test Bed Initiative project, which aims to demonstrate the feasibility of alternative options for retrieving and treating low-activity tank waste at the site in Washington state.

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.

The municipality of South Bruce, located near the Bruce nuclear power plant in southwestern Ontario, voted narrowly in favor of being a willing host to a potential deep geologic repository for Canada’s spent nuclear fuel. The official declaration of results from the municipality showed that 51 percent of South Bruce residents voted in favor of the referendum, with 1,604 voting "yes" and 1,526 voting "no." Voter participation was 69 percent, surpassing the 50 percent voter turnout required to make the vote binding by law.

Sweden’s Land and Environmental Court has granted the Swedish Nuclear Fuel and Waste Management Company (Svensk Kärnbränslehantering AB, or SKB) an environmental permit to build and operate a geologic repository for the country’s spent nuclear fuel near the Forsmark nuclear power plant, about 86 miles north of Stockholm. The permit also includes the building of a spent fuel encapsulation plant at the central interim storage facility for spent nuclear fuel at Oskarshamn, about 200 miles south of Stockholm.

The U.S. Navy’s Surface Ship Support Barge, converted in the 1960s from a WWII T2 tanker to a support barge to accept spent nuclear fuel during the refueling of nuclear aircraft carriers, was dismantled and disposed of by the nuclear decommissioning company APTIM as a first-of-its-kind vessel dismantlement project for the Navy. The project was executed under contract with Naval Sea Systems Command; however, regulatory oversight was accomplished through an interagency framework agreement between the U.S. Navy and the Nuclear Regulatory Commission.

Deep Isolation announced that it hosted its third technical workshop for the UPWARDS project, a Department of Energy Advanced Research Projects Agency-Energy (ARPA-E) initiative aimed at developing a universal canister system (UCS) for the disposal of radioactive waste streams from advanced reactors. The workshop, held at R-V Industries in Honey Brook, Pa., focused on the large-scale manufacturing and commercialization of the UCS.

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.

BWX Technologies announced that the Department of Energy has approved Hanford Tank Waste Operations & Closure (H2C) to begin work under a contract valued at up to $45 billion to clean up tank waste at the Hanford Site near Richland, Wash. H2C is a limited liability company made up of BWXT Technical Services Group, Amentum Environment and Energy, and Fluor Federal Services.

The Department of Energy is proposing to fully decommission the Submarine 5th Generation General Electric (S5G) prototype at the Naval Reactors Facility on the Idaho National Laboratory site. Along with the Environmental Protection Agency and the state of Idaho, the DOE has initiated a 30-day public comment period (ending November 14) on the planned end state for the facility and its defueled reactor vessel.

With the recent mobilization at the site of the former SM-1A nuclear power plant at Fort Greely, Alaska, the Radiological Health Physics Regional Center of Expertise, located at the U.S. Army Corps of Engineers’ Baltimore District, began its work toward the decommissioning and dismantlement of its third nuclear power plant, this time located just 175 miles south of the Arctic Circle.

Focused on the post-cleanup management of closed Department of Energy sites, the DOE Office of Legacy Management (LM) is responsible for the long-term surveillance and maintenance of more than 100 sites across the United States and Puerto Rico associated with past radiological and nuclear material production and testing, and energy research—some dating from as early as the Manhattan Project. With cleanup completed, many of these sites have been put to beneficial reuse and repurposed as parks and nature preserves, where visitors can witness the return of thriving ecosystems.

Robotics is fast becoming a go-to for nuclear decommissioning advances, and several organizations working in West Cumbria, England, the hub of the United Kingdom’s energy sector, have formed a partnership to share insight and work together to address common challenges and opportunities. Cumbria Robotics Cluster is an ambitious initiative powered by the Industrial Solutions Hub (iSH) to harness and expand the region’s renowned capabilities in cutting-edge engineering and problem solving.

Beginning last week, the two Department of Energy offices responsible for the environmental cleanup of the department’s Hanford Site have been combined under a new name: the Hanford Field Office. Previously, management of the 586-square-mile site near Richland, Wash., was split between the Richland Operations Office and the DOE Office of River Protection (ORP).
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.
