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.

A silver chloride–based cleanup technology is expected to reduce radioactive iodine-129 contamination found in soil and groundwater near the center of the Department of Energy’s Savannah River Site in South Carolina to levels well below regulatory limits. The I-129 was created during the production of plutonium and tritium at the site throughout the Cold War era.

The Department of Energy’s Office of Environmental Management has released a draft request for proposals (RFP) for a new contract worth up to $21.5 billion over 10 years for the operation of the Savannah River Site in South Carolina. The draft RFP contemplates a standalone, performance-based, cost-plus-award-fee management and operating (M&O) contract containing discrete contract line-item numbers/specifications with the potential for other contract types.

As the workers at Hanford’s Waste Treatment and Immobilization Plant (WTP) move closer to starting up the first of two melters inside the plant’s Low-Activity Waste (LAW) Facility, plant contractor Bechtel National has launched the Journey to Melter Heatup website that explains the WTP commissioning process, including critical activities such as the loss-of-power test and the melter heatup process.

Ukraine’s State Nuclear Regulatory Inspectorate (SNRIU) has authorized the operation of Chernobyl’s Interim Storage Facility (ISF-2), allowing spent nuclear fuel from the plant’s three undamaged reactors to be loaded into the dry storage facility. The handover of the ISF-2 operating license was carried out during a ceremony held on April 26, the 35th anniversary of the Chernobyl accident, and was attended by Ukraine’s president, Volodymyr Zelensky.

Nuclear Waste Partnership (NWP), the management and operations contractor for the Department of Energy’s Waste Isolation Pilot Plant in southeastern New Mexico, announced that it has awarded a subcontract valued at approximately $163 million to The Industrial Company (TIC) to complete the construction of the transuranic waste repository’s Safety Significant Confinement Ventilation System (SSCVS).

The Waste Isolation Pilot Plant in southeastern New Mexico is once again accepting shipments and processing transuranic waste following a two-month annual maintenance outage. According to the Department of Energy, WIPP is back to accepting five waste shipments per week, with post-pandemic plans to increase shipments to 10 per week.

The State of New York will withdraw its lawsuit against the transfer of Indian Point’s license to Holtec International for decommissioning under a provisional agreement signed on April 14. In exchange, Holtec has agreed to maintain a minimum of $400 million in Indian Point’s decommissioning trust fund for the next 10 years.

A project to reduce by approximately half the high-security protected area at the Department of Energy’s Y-12 National Security Complex in Oak Ridge, Tenn., will avoid millions of dollars in costs and accelerate cleanup, the DOE’s Office of Environmental Management (EM) announced.
