Department of Energy contractor Central Plateau Cleanup Company recently completed final demolition activities at the Hanford Site’s former Plutonium Finishing Plant, which was once one of the most hazardous facilities in the DOE’s Office of Environmental Management (EM) cleanup complex.

Check out this time-lapse video of the plant’s demolition from October 2016 through November 2021.

As the Department of Energy's Hanford Site prepares for around-the-clock operations for tank waste disposal, workers at the site's 242-A Evaporator are upgrading equipment used to remove water from the tank waste and the systems that transfer waste to and from large underground containers. The upgrades will also extend the evaporator’s service life.

With a notice published in the December 21 Federal Register, the Department of Energy has affirmed its interpretation of the statutory term “high-level radioactive waste” to mean that not all wastes from the reprocessing of spent nuclear fuel are HLW. The DOE said it interprets the statutory term such that some reprocessing wastes may be classified as non-HLW and may be safely disposed of in accordance with its radiological characteristics.

The Nuclear Regulatory Commission has approved the transfer of the Palisades nuclear power plant licenses from Entergy Nuclear Operations to Holtec International, as owner, and Holtec Decommissioning International (HDI), as decommissioning operator. Holtec and HDI intend to decommission the single-unit pressurized water reactor, located in Covert, Mich., under an accelerated schedule.

Four work crews have become qualified to operate the control room at the Hanford Site's Waste Treatment and Immobilization (VIT) Plant, which is targeted for operation in 2023.

When the Department of Energy, the state of Idaho, and the Environmental Protection Agency signed a federal facility agreement and consent order in December 1991, the agencies outlined a plan to investigate and clean up, if necessary, more than 500 individual waste areas within the 890-square-mile Idaho National Laboratory (INL) Site, which was established in 1949 to design, build, and test nuclear reactors.

The President’s Special Session at the 2021 ANS Winter Meeting and Technology Expo, held Thursday morning, explored the current impasse over the management of spent nuclear fuel in the United States, with leaders from Congress and representatives from the Department of Energy and the U.S. Government Accountability Office sharing the work they are doing in an effort to break that impasse.

The Department of Energy has restarted its consent-based siting process for identifying sites to store the nation’s spent nuclear fuel. Yesterday, the DOE issued a request for information that “will be used to further develop DOE’s consent-based siting process and overall waste management strategy in an equitable way.”

Having completed all startup testing of components and systems, the Waste Treatment and Immobilization Plant (WTP) at the Hanford Site near Richland, Wash., has moved to the commissioning phase, the Department of Energy’s Office of Environmental Management (EM) announced last week. During the commissioning phase, the final steps will be taken to prepare for the vitrification of radioactive and chemical waste as part of Hanford’s Direct-Feed Low-Activity Waste (DFLAW) program.

The license for Pacific Gas & Electric Company’s Humboldt Bay Unit 3 nuclear power plant near Eureka, Calif., has been terminated by the Nuclear Regulatory Commission, and the site has been released for unrestricted use. A 65-MWe boiling water reactor plant, Humboldt Bay-3 operated commercially from 1963 to 1976.

The New Mexico Court of Appeals upheld a permit modification allowing the Department of Energy and its contractor Nuclear Waste Partnership (NWP) to change how the volume of transuranic (TRU) waste emplaced at the Waste Isolation Pilot Plant near Carlsbad is calculated.

In a prerecorded video speech to last week’s Decommissioning Strategy Forum in Summerlin, Nev., Nuclear Regulatory Commission commissioner David Wright addressed public concerns about the growing number of utilities transferring their nuclear power reactor licenses to outside companies for accelerated decontamination and decommissioning after plant closure.

“While the NRC’s reactor decommissioning financial assurance program considers the potential for non-utility companies to conduct decommissioning, we have heard concerns about the use of these new license transfer models, given the significant acceleration of decommissioning schedules and withdrawals from decommissioning trust funds,” Wright said in his November 1 speech.

The Department of Energy has indefinitely delayed its final request for proposal (RFP) for the management and operations contract for the department’s Savannah River Site in South Carolina. The contract’s postponement was announced in a brief notice posted to the DOE’s Office of Environmental Management Consolidated Business Center website on November 9.

The Department of Energy is considering solidifying 2,000 gallons of Hanford’s tank waste and disposing of it as low-level radioactive waste at an off-site facility. A virtual public meeting on the proposed disposal plan is scheduled for November 18.

The Department of Energy’s Office of Environmental Management (EM) has authorized the use of a second mega-volume saltstone disposal unit (SDU) at the Savannah River Site in South Carolina. Savannah River Remediation (SRR), EM’s liquid waste contractor at SRS, received Critical Decision-4 for Saltstone Disposal Unit 7, marking the final step in the approval process before beginning operations.

UCOR, the primary contractor for the Department of Energy’s Oak Ridge Office of Environmental Management (OEM), recently transitioned to a new waste tracking system that improves how shipments are tracked from work sites to disposal locations.

The new system includes upgraded radio frequency identification (RFID) tracking for trucks, as well as new hardware and software, allowing for an automated tracking operation that delivers up-to-the-minute waste disposal data.

A group of women engineers with Washington River Protection Solutions (WRPS) has established a series of monthly lunchtime presentations aimed at empowering and mentoring other women engineers. WRPS is the Department of Energy’s tank operations contractor at the Hanford Site, near Richland, Wash.

“Engineering is a very competitive field,” said Elaine Porcaro, chief engineer for the DOE’s Office of River Protection tank farms projects. “It is inspiring to see that these women have taken the initiative to establish a forum to support and promote each other, sharing their successes and key learnings in order to pave the way for other women to be successful.”

The Nuclear Regulatory Commission on Wednesday approved a proposed rule to amend its regulations for nuclear power plants that are transitioning from operations to decommissioning. After changes requested by the NRC commissioners are made by agency staff, the proposed rule will be published in the Federal Register, initiating a 75-day comment period.

The Department of Energy’s Office of Environmental Management (EM) has awarded Savannah River Mission Completion (SRMC), of Lynchburg, Va., the Integrated Mission Completion Contract at the Savannah River Site near Aiken, S.C. The single-award, master indefinite delivery/indefinite quantity contract has an estimated contract ceiling of approximately $21 billion over a 10-year ordering period, with cost-reimbursement and fixed-price task orders to define the contract performance.
