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.

DGR Grant Construction will construct a safe-storage enclosure over the K East Reactor building at the Department of Energy’s Hanford Site in Washington state. Two construction subcontracts, worth about $9.5 million, were awarded to the Richland, Wash.–based company by Central Plateau Cleanup Company, the DOE’s Richland Operations Office site cleanup contractor.

According to the Department of Energy’s Office of Environmental Management (EM), shipments of transuranic waste to the Waste Isolation Pilot Plant in New Mexico are back to pre-pandemic levels, with the deep underground repository receiving 12 shipments in one week this summer.
The DOE recently completed startup testing on the uninterruptable electrical power system for Hanford’s Low-Activity Waste Facility.
Department of Energy workers recently finished startup testing of a battery-powered backup electrical system for the Low-Activity Waste (LAW) Facility at the Hanford Site near Richland, Wash. According to the DOE’s Office of Environmental Management (EM), the uninterruptable electrical power system is vital to safeguarding the facility, part of Hanford’s Waste Treatment and Immobilization Plant, in the unlikely event of a temporary power loss to the plant.

The Department of Energy’s Office of Environmental Management has doubled the number of work shifts for employees in glove box operations at its Savannah River Site in South Carolina. The increased work pace will help the department meet its commitment to South Carolina to remove surplus plutonium from the state, the DOE said.

The Department of Energy’s Office of Environmental Management has issued a final request for proposals for a transportation services contract for the Waste Isolation Pilot Plant in southeastern New Mexico. The current WIPP transportation services contract, held by CAST Specialty Transportation, expires on May 27, 2022.
Demolition of the last of 11 structures at the former Y-12 Biology Complex at Oak Ridge was completed in June, and the removal of the building’s slab foundation is scheduled to be completed this fall. (Photo: DOE)
Crews with the Department of Energy’s Office of Environmental Management (EM) have completed the demolition of Building 9207, the largest and final building at the former Biology Complex at the Y-12 National Security Complex in Oak Ridge, Tenn., the DOE announced this week. Removal of the massive six-story, 255,000-square-foot building ushers in a new chapter of transformation at Y-12, the DOE said.
