Waste Management

The Salt Waste Processing Facility at the Department of Energy’s Savannah River Site has performed largely as expected, processing more than one million gallons of radioactive waste during its first eight months of operation, the DOE reported on June 8. The SWPF is being used to treat the majority of the site’s remaining liquid radioactive waste, generated from the production of nuclear materials.

The Department of Energy has issued a final request for proposals for a 10-year, $3 billion management and operating contract for the Waste Isolation Pilot Plant near Carlsbad, N.M. The current M&O contract, held by Nuclear Waste Partnership, expires on September 30.

Final cleanup activities at the Hanford Site’s demolished Plutonium Finishing Plant have resumed following a pause in work prompted by the COVID-19 pandemic, the Department of Energy announced. Crews with the DOE’s Richland Operations Office and site contractor Central Plateau Cleanup Company will remove, package, and dispose of rubble remaining from the demolition of the plant’s plutonium reclamation facility, which was torn down in 2017.

Towed from its home in Newport News, Va., the U.S. Navy’s Surface Ship Support Barge has arrived in Mobile, Ala., for decommissioning, Advance Local Alabama reported on June 1. The 268-foot-long barge operated from 1964 to 2016, supporting the Navy's nuclear vessel refueling and functioning like a spent fuel pool at a commercial nuclear power plant.

The transfer of the Indian Point nuclear power plant from Entergy to Holtec International and its subsidiaries was completed last week. Under the asset transfer deal, Holtec Indian Point becomes owner of the closed plant, with Holtec Decommissioning International serving as the site’s license holder and decommissioning operator.

The Department of Energy’s Office of Environmental Management will award the Idaho Cleanup Project contract for the Idaho National Laboratory site to Idaho Environmental Coalition (IEC), of Tullahoma, Tenn. The contract has an estimated ceiling of approximately $6.4 billion over 10 years, with cost reimbursement and fixed-price task orders to define the contract performance.

Do you have TRU waste with characteristics and/or prohibited items not acceptable in their current configuration for transportation and/or disposal at WIPP? Such as liquids, oxidizers, corrosives, reactive materials, flammable liquids, and aerosol cans? Are you sorting and segregating the non-compliant waste forms and then developing process/treatment approaches (i.e., solidification, grouting, deactivation, etc.) to ensure your final waste form will meet transportation and WIPP’s acceptance requirements?

Work crews recently placed a final radioactive waste shipment into the Idaho National Laboratory site’s largest waste disposal area. The Department of Energy's Office of Environmental Management noted on May 25 that it would begin closing the facility, fulfilling its commitment to the state of Idaho.

Paving the way for increased automation in nuclear decontamination and decommissioning and waste management, French nuclear company Framatome announced that testing has confirmed the operation of its robotic systems for handling and sorting high-dose waste components.

A collaboration agreement signed by Ontario Power Generation’s Center for Canadian Nuclear Sustainability, Canadian Nuclear Laboratories, and SNC-Lavalin will build on Ontario’s extensive nuclear industry expertise and skilled workforce to support the decommissioning of CANDU reactors in Canada and around the world, according to a May 13 press release from the organizations. The work will include the decommissioning of OPG’s Pickering nuclear power plant following the end of commercial operations in 2025.

Department of Energy contractor Savannah River Remediation (SRR) announced on May 11 that it has completed a salt dissolution campaign in Tank 37, one of the underground tanks storing high-level radioactive liquid waste at the Savannah River Site (SRS) in South Carolina.

Utah-based EnergySolutions has entered into a definitive agreement with Dominion Energy to acquire the closed Kewaunee nuclear power plant for prompt decommissioning. Located about 30 miles southeast of Green Bay, Wis., the single-unit, 574-MWe pressurized water reactor was shut down in May 2013 for financial reasons.

Posiva Oy, the company responsible for the disposal of Finland’s spent nuclear fuel, announced last week that it has begun excavating the first disposal tunnels at the Onkalo deep geologic repository near the Olkiluoto nuclear power plant.

The Nuclear Regulatory Commission is set to allow about 2 million gallons of low-level radioactive wastewater from the Vermont Yankee nuclear power plant, currently undergoing decommissioning, to be disposed of at an Idaho waste facility. As published in the May 7 Federal Register, the NRC has issued an environmental assessment and finding of no significant impact for a request by NorthStar Nuclear Decommissioning to dispose of the wastewater at US Ecology Idaho’s waste facility near Grand View.

A federal court has dismissed a claim by the Nuclear Energy Institute that the Nuclear Regulatory Commission had reversed decades of established policy by requiring owners and operators of nuclear power plants to obtain the agency’s approval to dispose of low-level radioactive waste, even in NRC Agreement States.

At issue was a letter the NRC sent to NEI in 2019, stating that licensees must receive agency approval before disposing of LLW. In response, NEI filed a lawsuit against the NRC, claiming that the letter imposes new obligations on licensees without the NRC’s having followed rulemaking procedures required by the Administrative Procedure Act, including publishing notice of the new policy and receiving input from stakeholders prior to implementation.

Workers at the Department of Energy’s Hanford Site near Richland, Wash., recently completed testing a mock-up of a system that will be used to isolate and stabilize about 15,000 pounds of radioactive debris in the site’s K West Reactor spent fuel storage basin.

Granholm

The American Nuclear Society joined seven other prominent nuclear organizations in submitting a letter to energy secretary Jennifer Granholm requesting that the Department of Energy establish an office dedicated to developing and managing an integrated nuclear waste storage, transportation, and disposal program. The letter asks that the new office report directly to the energy secretary.

Specifically, the office would do the following:

• Provide a focal point for work on spent nuclear fuel and high-level radioactive waste.
• Facilitate necessary engagement with external stakeholders.
• Demonstrate an intent and commitment to take meaningful action.

The Nuclear Waste Technical Review Board (NWTRB), created by Congress to evaluate the technical and scientific validity of the Department of Energy’s work related to the management and disposal of spent nuclear fuel and high-level radioactive waste, has released a report titled Six Overarching Recommendations for How to Move the Nation’s Nuclear Waste Management Program Forward.

The Department of Energy announced that it has determined that an underground single-shell waste tank at its Hanford Site near Richland, Wash., is likely leaking into the soil beneath the tank. The DOE said that the leaking tank poses no increased health or safety risk to the Hanford workforce or the public.

During the annual National Cleanup Workshop, held virtually in September of last year due to the COVID-19 health crisis, William “Ike” White, senior advisor to the under secretary for science in the Department of Energy’s Office of Environmental Management, said that despite the pandemic, 2020 was an inflection year for the DOE and his office.
