Vitrification & Grout

Site preparation recently began for the next large-scale Saltstone Disposal Unit (SDU) at the U.S. Department of Energy’s Savannah River Site in South Carolina, according to a post Monday on the site’s Facebook page. Liquid waste contractor Savannah River Remediation (SRR) has completed excavation of the location for SDU 8, a 32-million-gallon megavolume concrete structure that will permanently […]

HENDERSON, Nev. — Communities along the Georgia-South Carolina line, as well as U.S. Energy Department cleanup vendors, are closely tracking federal consideration of disposal options for 10,000 gallons of vitrified wastewater from the Savannah River Site. When the Energy Department published its proposed reinterpretation of the definition of radioactive high-level waste (HLW) in June, it […]

Key components of the $17 billion Waste Treatment Plant at the Hanford Site in Washington state might miss the current deadline to begin operation, the U.S. Energy Department acknowledged this week.

Interim salt waste treatment at the Savannah River Site in South Carolina has been shut down, as the Department of Energy prepares to start up the larger-scale Salt Waste Processing Facility (SWPF) in December. Since April 2017, workers at the 310-square-mile site have been operating the Actinide Removal Process (ARP) and Modular Caustic Side Solvent Extraction Unit (MCU): two […]

The U.S. Energy Department and contractor Bechtel National reached a key milestone this week toward operation of the $17 billion Waste Treatment and Immobilization Plant at the Hanford Site in Washington state. The company and DOE’s Office of River Protection held a ribbon-cutting ceremony Monday to mark the start of testing on equipment within an […]

The U.S. Defense Nuclear Facilities Safety Board (DNFSB) has officially closed an 8-year-old recommendation that identified significant failings in the safety culture for the Waste Treatment Plant (WTP) being built at the Department of Energy’s Hanford Site in Washington state. “The Board has concluded that the Department of Energy has adequately addressed the underlying causes […]

The U.S. Department of Energy and the Washington state Department of Ecology are taking public comments through Sept. 16 on a proposed change to the dangerous waste permit for the Hanford Site. If approved, the state permit modification would allow DOE to connect a backup waste transfer line from the Waste Treatment and Immobilization Plant’s […]

The Washington state Department of Ecology has denied the Department of Energy’s application for a permit to cover Test Bed Initiative (TBI) work at the Hanford Site, but expressed support for the project. Despite the initial setback, the letter of denial issued March 15 also said there is a better and possibly quicker way for […]

Operations at a key Savannah River Site waste facility are expected to increase later this year, in unison with the startup of the Salt Waste Processing Facility (SWPF) at the Department of Energy facility in South Carolina. Staffing increases are also expected at the SRS Saltstone Production Facility, which mixes treated salt waste with a cement […]

Department of Energy contractor CH2M HILL BWXT West Valley (CHBWV) has removed virtually all the waste generated from demolition of the vitrification plant at the West Valley Demonstration Project in New York state. About 460 containers of debris have been sent from the site at the town of Ashford to off-site facilities, the Energy Department […]

The Department of Energy has determined that its current operating plans for the Waste Treatment Plant at the Hanford Site do not require a supplement to a comprehensive 2012 supplemental environmental impact statement (EIS) on radioactive tank waste at the Washington state cleanup complex. The agency concluded in a new analysis that altered plans for […]

The GeoMelt vitrification system installed at Perma-Fix Northwest in Richland, Wash., has wrapped up its initial demonstration melt of sodium-contaminated radioactive waste from the Department of Energy’s Idaho National Laboratory (INL). Veolia Nuclear Services Federal Services, which owns the technology, in September received the INL contract to “demonstrate at full-scale” the system’s capabilities to process the reactive […]

Workers at the Hanford Site on Wednesday resumed stabilizing the second PUREX Plant radioactive waste storage tunnel with concrete-like grout to prevent its possible collapse. The project was suspended for several days after an Oct. 26 incident in which steam was spotted coming from a small building attached to the tunnel, leading to a precautionary […]

Workers at the Hanford Site are preparing to start filling the PUREX Plant’s second waste storage tunnel with concrete-like grout as soon as this week, after the Washington state Department of Ecology on Sept. 28 approved the interim stabilization work to prevent collapse. In May 2017, there was a partial collapse of the older and […]

A newly inked deal has paved the way for Veolia Nuclear Solutions to demonstrate its patented GeoMelt technology to process radioactive waste sent from the Idaho National Laboratory (INL). Under the agreement, announced Sept. 25, INL management and operations contractor Battelle Energy Alliance (BEA) will ship some drums with small amounts of radioactive contaminated sodium […]

The Department of Energy must hold additional public hearings in the Pacific Northwest on a proposal that could lead to a limited amount of radioactive waste being grouted in place in the Hanford Site’s underground storage tanks, according to three members of Washington state’s congressional delegation. Sens. Patty Murray and Maria Cantwell, along with Rep. […]

There is a diminishing likelihood that the long-awaited Integrated Waste Treatment Unit (IWTU) at the Idaho National Laboratory will begin operations this year, as had been hoped in some quarters, the Defense Nuclear Facilities Safety Board indicated recently.
