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.”

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.

Pennsylvania’s Department of Environmental Protection (DEP) is intervening in the proceeding for FirstEnergy Corporation’s application to transfer the license for Unit 2 of the Three Mile Island nuclear power plant to an EnergySolutions subsidiary for decommissioning. The Pennsylvania DEP filed its petition to intervene in the transfer of TMI-2’s possession only license, along with a request to extend the time to file a request for a hearing, to the Nuclear Regulatory Commission.

The startup of tank waste treatment activities at Hanford’s Waste Treatment and Immobilization Plant took a step forward in April with the Department of Energy’s issuing a request for information for the operation of the WTP Direct Feed Low-Activity Waste (DFLAW) facilities. According to the DOE, the RFI solicits input, via capability statements, from potential contractors with the specialized capabilities necessary to meet all of the major elements of scope for the upcoming competitive procurement for the operation of WTP DFLAW facilities, which will treat and vitrify for disposal low-activity waste from underground storage tanks at the Hanford Site near Richland, Wash.

Decommissioning work in parts of the Fukushima Daiichi plant in Japan has been delayed after engineers discovered that sandbags placed in the basements of buildings near Units 1 and 3 were found to contain excessive radiation levels. Tokyo Electric Power Company (TEPCO) operates the plant and is in charge of the decommissioning efforts following the accident caused by the earthquake and tsunami on March 11, 2011.

Recognizing the impacts of the current COVID–19 pandemic, the Nuclear Regulatory Commission has decided to extend the public comment period on a proposed interpretation of its low-level radioactive waste disposal regulations. The new deadline for comments is July 20. The proposed LLW interpretive rule, announced on March 6, would permit licensees to dispose of waste by transfer to persons who hold specific exemptions for the purpose of disposal (NN, Apr. 2020, p. 47).

The Department of Energy’s Office of Environmental Management (EM) has reduced operations at the majority of its cleanup sites as a result of stay-at-home orders in some states. The DOE said that most EM sites have transitioned to “essential mission-critical operations status with maximum telework” as a response to the coronavirus pandemic. The DOE said that EM is continuing to monitor developments associated with COVID-19 and is evaluating its potential impacts on projects.

An International Atomic Energy Agency team of experts said in a review published on April 2 that the two options for the controlled disposal of treated water stored at the Fukushima Daiichi nuclear power plant are “technically feasible.” A Japanese advisory subcommittee outlined the two options—vapor release and discharge to the sea—for the water that is being stored at the plant following the 2011 accident.

The Department of Energy’s Office of Environmental Management (EM) has issued an outline of planned accomplishments over the next decade to capitalize on progress it has made in cleaning up former government weapons and research sites over its first 30 years. The release of the 66-page report, A Time of Transition and Transformation: EM Vision 2020-2030, was announced on March 9 by William “Ike” White, DOE senior advisor for environmental management, during the 2020 Waste Management Conference in Phoenix, Ariz.

The NRC approved the transfer of the reactor's license to ADP CR3 for decommissioning.

The Nuclear Regulatory Commission approved the license transfer for the Crystal River-3 nuclear power plant from Duke Energy Florida to ADP CR3, enabling active decommissioning of the shuttered nuclear power plant, the agency announced on April 1.
