The Department of Energy has signed an amendment to a 2016 sales agreement with Global Laser Enrichment (GLE) that will provide the company with access to large stockpiles of DOE-owned depleted uranium hexafluoride (DUF6) tails as GLE looks to build its proposed uranium enrichment facility at the DOE’s Paducah site in Kentucky. As announced on June 5, the amendment is one of the conditions of a 2019 agreement by Australia’s Silex Systems Limited, Canada’s Cameco Corporation, and GE Hitachi Nuclear Energy for the restructuring of GLE, the exclusive licensee of Silex’s laser uranium enrichment technology.

Separately, the DOE announced on June 5 that it has issued a formal record of decision for the shipment and disposal of depleted uranium oxide from the former gaseous diffusion plants at the department’s Paducah and Portsmouth sites in Ohio to one or more disposal facilities in the western United States.

The antinuclear organization Beyond Nuclear has filed an appeal with the U.S. Court of Appeals for the District of Columbia Circuit requesting a review of the Nuclear Regulatory Commission’s decision to deny its petition against Holtec International’s application to build and operate a consolidated interim storage facility (CISF) for spent nuclear fuel in southeastern New Mexico.

The Department of Energy’s Office of Environmental Management on May 27 issued a final request for proposals for the cleanup of the Idaho National Laboratory site, near Idaho Falls, Idaho, and the Fort Saint Vrain facility near Platteville, Colo. The 10-year contract for the projects—collectively called the Idaho Cleanup Project—has an estimated ceiling of about $6.4 billion.

Under an agreement with the state of California, the Department of Energy will soon resume environmental cleanup of the Energy Technology Engineering Center (ETEC) at the Santa Susana Field Laboratory site in Ventura, Calif., about 36 miles northwest of Los Angeles. In a legal order signed on May 19 with the California Department of Toxic Substances Control, the department has agreed to demolish 10 of the remaining DOE-owned buildings within the ETEC, including several of the most contaminated buildings.

The Department of Energy has awarded a $13-billion tank closure contract for services at its Hanford Site, near Richland, Wash. The 10-year contract was awarded on May 14 to Hanford Works Restoration, a joint venture of BWXT Technologies and Fluor Corporation that also includes DBD and INTERA, two preselected small businesses that provide specialized modeling and regulatory expertise, respectively.

Hanford Works Restoration will take over from Hanford’s current tank waste contractor, Washington River Protection Solutions (WRPS), whose contract expires at the end of September. The WRPS contract includes a clause that allows the DOE to end the contract earlier to align with a 60-day transition to the new contract.

Jeff England, director of transportation projects for NAC International, pointed to the large stainless steel canister, which looked like a giant-­sized silver dumbbell, perched on the flatbed of a semitrailer truck parked in the middle of the expansive exhibit hall in the Phoenix Convention Center. NAC, a provider of nuclear storage, transportation, and consulting services, was using the 2020 Waste Management Conference, held March 8–12 in Phoenix, Ariz., to unveil its newest transport casks, the Optimus-­H and Optimus-­L.

“These are a different niche,” England said of the casks, which were designed to transport radioactive materials, including remote-­handled transuranic waste, high-­activity intermediate-­level waste, low-­enriched uranium, and fissile materials. “You have a lot of [small] drum-­sized packages, and you also have a lot of big packages that will hold around 10 55-­gallon drums. But there’s not anything in between. We hold a 110-­gallon drum capacity.”

Scott Dempsey is the senior vice president of waste management business development for EnergySolutions, a nuclear services company headquartered in Salt Lake City, Utah.

Dempsey has 29 years of experience in nuclear power plant waste operations, as well as in commercial waste processing, packaging, transportation, and disposition. He has received all relevant Department of Transportation, Resource Conservation and Recovery Act, Occupational Safety and Health Administration, radiological, and other industry certifications required for handling and disposition of wastes. Dempsey holds a bachelor’s degree in finance, and his previous experience includes management positions at F.W. Hake Associates, Duratek Inc., and MHF Services.

EnergySolutions has operations across the United States, Canada, and Japan. The company provides services to commercial utilities and U.S. and Canadian governments and laboratories. Its work includes decommissioning nuclear power plants and safely containing, transporting, recycling, processing, and disposing of nuclear material.

Dempsey talked about the company’s cask and container activities with Nuclear News Editor-in-Chief Rick Michal.

The Department of Energy’s Office of Environmental Management has not followed best practices or DOE policy in pursuing alternatives for pretreating radioactive tank waste at the Hanford Site, near Richland, Wash., according to a report released on May 12 by the Government Accountability Office. The DOE has spent over $400 million since 2013 looking into alternatives to pretreating Hanford’s low-activity waste (LAW), yet the department has not properly defined a mission need or a life-cycle cost estimate for its preferred alternative, according to the report.

The 2020 Waste Management Conference, held March 8–12 in Phoenix, Ariz., kicked off just days before the World Health Organization declared the spread of the novel coronavirus a pandemic. When the conference began, it was still unclear how extensive the coronavirus outbreak would be, and meeting organizers later learned that two attendees were tested for COVID-19, the disease caused by the virus, in the days following the meeting. Fortunately, neither of the attendees tested positive.

The global engineering company Jacobs, under a contract with Radioactive Waste Management Ltd. (RWM), will be studying the release of radioactivity from irradiated graphite taken from reactor core samples at the United Kingdom’s nuclear power plants. According to Jacobs, the research will support RWM, a subsidiary of the U.K. government’s Nuclear Decommissioning Authority, in its analysis of graphite behavior and the options for graphite waste management in the future.

The Nuclear Regulatory Commission is requesting comments on its draft environmental impact statement (EIS) for Interim Storage Partners’ (ISP) proposed consolidated interim storage facility (CISF) for spent nuclear fuel and greater-than-Class C (GTCC) waste in West Texas. The NRC published notice of the draft EIS in the May 8 Federal Register with a deadline of September 4 to submit comments. The NRC said that it is extending the usual 60-day comment period to allow more time for members of the public to submit comments during the COVID-19 health emergency.

Comments can be submitted through the federal rulemaking website with a search for Docket ID NRC–2016–0231.

The Nuclear Regulatory Commission has released a draft environmental impact statement (EIS) for Interim Storage Partners’ (ISP) proposed consolidated interim storage facility (CISF) for spent nuclear fuel and greater-than-Class C (GTCC) waste in West Texas. Based on its environmental review of the CISF, the NRC staff issued a preliminary recommendation that an NRC license be granted to ISP to construct and operate the CISF to temporarily store up to 5,000 metric tons of uranium (MTU) in commercial spent fuel and GTCC waste for a licensing period of 40 years.

Deep in the underground of a New Mexico desert, the Department of Energy is studying the effects of high-level, heat-generating radioactive waste on water migration in the salt formations. At the Waste Isolation Pilot Plant (WIPP) near Carlsbad, N.M., a collaboration between Sandia, Los Alamos, and Lawrence Berkeley National Laboratories is performing a series of borehole-scale process tests, called the Brine Availability Test in Salt (BATS) project.

The National Nuclear Security Administration’s early-stage plan to dilute and dispose of 34 metric tons of surplus plutonium in the Waste Isolation Pilot Plant (WIPP) is technically viable, according to an April 30 release from the National Academies of Sciences, Engineering, and Medicine.

The Nuclear Regulatory Commission has rejected a number of contentions filed against Holtec International’s application to build and operate a consolidated interim storage facility (CISF) for spent nuclear fuel in southeastern New Mexico. On April 23, the commissioners voted to dismiss five separate appeals of the presiding Atomic Safety and Licensing Board’s decision to deny requests to intervene in the proceeding for Holtec’s license application.
