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 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.
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.
DOE liquid waste contractor Savannah River Remediation is moving forward with Saltstone Disposal Unit projects to support the Salt Waste Processing Facility at the Savannah River Site.
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.

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.

The Department of Energy’s Office of Environmental Management (EM) announced that it has accomplished another of its 2021 priorities by permanently disposing of a cumulative 12 million tons of uranium mill tailings from the Moab Site in Utah. The announcement, made on October 26, follows last week’s report by EM that it has shipped more than 1 million tons of tailings for disposal in fiscal year 2021, which ended on September 30, the largest annual amount since FY 2012.

The Department of Energy’s Office of Environmental Management (EM) has issued a final request for proposal (RFP) for the Hanford Integrated Tank Disposition Contract, a 10-year, $45 billion deal to oversee waste tank operations at the DOE’s Hanford Site near Richland, Wash. Proposals are due by December 20.

The Department of Energy’s Office of Environmental Management (EM) has released an animated video of the Direct-Feed Low-Activity Waste (DFLAW) Program at the Hanford Site near Richland, Wash. The video shows the integrated procedure for treating Hanford’s radioactive tank waste, a process EM says is a key component of its strategic cleanup vision.

Using a specialized radiation detector, Department of Energy cleanup contractor UCOR is characterizing a hot cell at Oak Ridge National Laboratory in preparation for its demolition. The detector overlays a radiation-intensity color-map on a picture of the environment and identifies gamma-emitting nuclides and their locations.

The Department of Energy’s Office of Environmental Management this week announced that after seven years, mining of the Waste Isolation Pilot Plant’s Panel 8 is finished. Created from an ancient salt formation 2,150 feet below the surface, Panel 8’s seven emplacement rooms are the next destination for transuranic waste brought to WIPP from DOE sites throughout the country.

Washington state and Oregon will receive approximately $33.5 million through four financial assistance grants from the Department of Energy to fund programs related to the cleanup of the department’s Hanford Site near Richland, Wash. The grants will support environmental response regulatory activities, emergency preparedness, and public information programs in the two states.
All four grants, which were noncompetitively awarded, are for fiscal years 2022 through 2026.

The Department of Energy is preparing to demolish two large, complex facilities at the Nevada Nuclear Security Site with ties to historical nuclear propulsion rocket development and testing programs. The DOE’s Environmental Management (EM) Nevada Program and its environmental program services contractor, Navarro Research and Engineering, have begun characterization and hazard reduction work on the site’s Engine Maintenance, Assembly, and Disassembly (EMAD) and Test Cell C (TCC) complexes.

The Savannah River Site is reducing the flow of hazardous and radioactive metal contaminants to South Carolina’s rivers and streams by injecting a mix of clean water and baking soda into the site’s groundwater. The base mix neutralizes groundwater that has become acidic as a result of SRS’s chemical separations work, helping restrict the flow of contaminants.
