Vitrification & Grout

The Department of Energy is making plans for the next phase of a demonstration project for commercial grouting and disposal of some of the low-activity radioactive waste held in underground storage tanks at the Hanford Site in Washington state. Planning is underway for Phase 2 of the test bed initiative, grouting 2,000 gallons of waste, […]

To prevent it from collapsing, the Department of Energy wants to start filling a second PUREX plant waste storage tunnel at the Hanford site with concrete-like grout in August — before the end of a scheduled public comment period about the effort. The Washington State Department of Ecology, lead state regulator at Hanford, plans a […]

The Savannah River Site is on pace to double-stack 358 canisters of treated radioactive liquid waste in this fiscal year, nearly double the 200 canisters stacked in fiscal 2017. All told, the Department of Energy facility near Aiken, S.C., has to date double-stacked 457 canisters of waste in one of its Glass Waste Storage Buildings […]

The Department of Energy has approved the documented safety analysis required for hot commissioning of the Low-Activity Waste Facility at the Hanford Site’s Waste Treatment Plant. Completion of the 7,000-page document is a required milestone for plant contractor Bechtel National, worth up to $6.65 million in fees. Bechtel National nuclear safety engineers spent three years […]

Researchers have vitrified 2 gallons of radioactive waste removed from a Hanford Site storage tank in a first-of-a-kind demonstration of the processes that will be used at the Waste Treatment Plant being built at the Energy Department facility in Washington state. Pacific Northwest National Laboratory researchers said it was the first time Hanford tank waste […]

A project to advance testing on whether some radioactive waste at the Department of Energy’s Hanford Site could be grouted rather than converted to glass would proceed under direction from legislation in the U.S. House of Representatives. On Wednesday, the House Appropriations Committee advanced its marked -up fiscal 2019 energy appropriations bill for a vote […]

An Energy Department contractor at the Savannah River Site (SRS) in South Carolina is seeking expressions of interest from subcontractors potentially interested in conducting concrete testing at Saltstone Disposal Unit (SDU) 7. Savannah River Remediation said in a May 8 post on a federal contracting website it is seeking responses by June 15. The AECOM-led […]

By John Stang Perma-Fix Environmental Services executives said Wednesday they see the potential for at least $5 million in annual revenue from a specialized radioactive waste vitrification system now being tested. In a conference call to discuss Perma-Fix’s latest quarterly earnings, President and CEO Mark Duff said there is enough contaminated sodium wastes at nuclear […]

At least one member of the House Committee on Oversight and Government Reform said last week he supports giving the Hanford Site in Washington state the ability to pursue lower-cost options for disposal of millions of tons of radioactive waste. Rep. Steve Russell (R-Okla.) said he favors giving the Energy Department extra flexibility at Hanford […]

Sen. Ron Wyden (D-Ore.) said Tuesday he plans to look into the transfer of the Energy Department project manager for the Waste Treatment Plant (WTP), at the Hanford Site in Washington state, shortly after he raised concerns about missing documentation on steel being used at the facility. On March 6, then-WTP Federal Project Director William […]

Gaps in safety assurance documents filed by Bechtel National are not serious enough to imperil the schedule for the Waste Treatment Plant the company is building at the Energy Department’s Hanford Site in Washington state, the head of DOE’s Hanford Office of River Protection said Monday. “No, I don’t think it’s a significant issue,” ORP […]

A Department of Energy review has found more quality assurance issues at the Waste Treatment Plant being built at the Hanford Site in Washington state. Quality records “needed to demonstrate that the important-to-safety structural steel could perform its safety function were either missing or of indeterminate quality,” according to a March 6 letter from DOE’s […]

The Department of Energy has named a new federal project director and assistant manager for the Hanford Site Waste Treatment Plant as the $17 billion project moves into a new phase.
