Work crews at the Department of Energy's Hanford Site recently completed the first transfer of test water from the Waste Treatment and Immobilization Plant's Effluent Management Facility to the nearby Liquid Effluent Retention Facility (LERF). The transfer of 6,000 gallons was the first simulation of the process that will be used to treat secondary liquid waste from the plant’s Low-Activity Waste Facility during operations to treat tank waste.
“This is a tremendous accomplishment that culminates years of work by our team and alumni toward being ready for hot commissioning,” said Valerie McCain, project director and senior vice president for Bechtel National, Inc. “It’s an important step for the entire Hanford team and our collective mission of protecting the Columbia River and its shoreline communities.”
Bechtel National is a contractor of the DOE's Office of Environmental Management's Office of River Protection.

The Department of Energy announced on Wednesday that the first large-scale treatment of radioactive and chemical waste from underground tanks at the Hanford Site near Richland, Wash., has begun with the start of operations of the Tank-Side Cesium Removal (TSCR) System.
The newly operational TSCR System removes radioactive cesium and solids from the tank waste. The treated waste will be fed directly to the nearby Waste Treatment and Immobilization Plant (WTP) for vitrification when the plant comes on line next year.

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.

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 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 is celebrating a major milestone in its tank waste mission at the Hanford Site near Richland, Wash. DOE tank operations contractor Washington River Protection Solutions has finished construction of the pipeline that will carry treated waste from an underground tank to the Waste Treatment and Immobilization Plant (WTP) for vitrification.

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.

A new wastewater filter system being installed at Hanford’s Effluent Treatment Facility (ETF) is expected to increase waste processing throughput, improve efficiency, and save money as the site in southeastern Washington gears up to treat tank waste, the Department of Energy announced.
