  • Hanford faces deadline crush to sort out grouting options

    By John Stang OLYMPIA, WASH. — The Hanford Site faces an extremely tight schedule to select both a technology and a destination for low-level radioactive waste intended to be immobilized in grout, the site’s top lawyer said here this week. “It is an aggressive timeline” said DOE’s chief Hanford counsel Mark Silberstein on the tight […]

  • DOE signals four-month delay in cold commissioning for Hanford waste treatment plant

    The Department of Energy expects to miss a legally binding Aug. 1 milestone for starting cold commissioning, making glass from non-radioactive liquid, at the Waste Treatment and Immobilization Plant at the Hanford Site in Washington state. DOE’s site manager for the former plutonium production complex, Brian Vance, told the Washington Department of Ecology of the […]

    Bechtel National has made its second batch of test glass at the Department of Energy’s Waste Treatment and Immobilization Plant at the Hanford Site in Washington state, the company said in various social media posts. “Our team poured molten clean test glass into a container from Melter 2 for the first time,” Bechtel said in […]

  • Hanford advisory panel raises questions on grout, other issues

    No decision has been made on whether grouting of some low-level radioactive tank waste at the Department of Energy’s Hanford Site would occur inside the 580-square-mile federal complex, or elsewhere, government attorneys told an advisory board Tuesday. A pathway to grout for some Hanford waste sparked questions from the Hanford Advisory Board, which was briefed […]

  • No slippage of glass-making timelines in ‘holistic’ agreement for Hanford

    A long-awaited settlement agreement rolled out Monday by state and federal agencies says the Department of Energy’s Hanford Site in Washington state still intends to start turning low-level radioactive tank waste into glass starting next year, with high-level waste vitrification to follow in the 2030s. DOE, the Washington state Department of Ecology (Ecology), and U.S. […]

  • Subs, small businesses short-changed from Bechtel vit contract, OIG finds

    Subcontractors and small businesses should have benefitted more over time from Bechtel National’s multibillion-dollar contract to build the Waste Treatment and Immobilization Plant at the Department of Energy’s Hanford Site in Washington state, DOE’s Office of Inspector General said. By self-performing so much of the work, “Bechtel reduced subcontracting opportunities for small businesses and other […]

  • Second melter heats up at Hanford vitrification plant

    Crews have started heating up the second melter for the Department of Energy’s Waste Treatment and Immobilization Plant at the Hanford Site in Washington state, the agency said Wednesday. “Last year, the Hanford team successfully completed heat up of the first melter and poured the first non-radioactive test glass,” at the Waste Treatment Plant built […]

  • IWTU hits a re-start snag, crews look for a fix

    The Department of Energy has scrubbed its goal to restart this month the Integrated Waste Treatment Unit at Idaho National Laboratory. “This week, while performing start-up operations at the Integrated Waste Treatment Unit (IWTU), crews identified abnormal conditions while performing testing in preparation for resuming waste processing,” DOE said in an email press release shared […]
