Having completed all startup testing of components and systems, the Waste Treatment and Immobilization Plant (WTP) at the Hanford Site near Richland, Wash., has moved to the commissioning phase, the Department of Energy’s Office of Environmental Management (EM) announced last week. During the commissioning phase, the final steps will be taken to prepare for the vitrification of radioactive and chemical waste as part of Hanford’s Direct-Feed Low-Activity Waste (DFLAW) program.

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.

As the workers at Hanford’s Waste Treatment and Immobilization Plant (WTP) move closer to starting up the first of two melters inside the plant’s Low-Activity Waste (LAW) Facility, plant contractor Bechtel National has launched the Journey to Melter Heatup website that explains the WTP commissioning process, including critical activities such as the loss-of-power test and the melter heatup process.

Improvements to Hanford’s 242-A Evaporator Facility continue to be made as the Department of Energy prepares to begin its direct-feed low-activity waste (DFLAW) approach to treating radioactive liquid waste at the site near Richland, Wash. The DOE announced on November 3 that its Office of River Protection and contractor Washington River Protection Solutions (WRPS) have completed several major upgrades and repairs at the evaporator, and more are planned.

Used to reduce waste volume by removing liquid from Hanford’s underground storage tanks, the 242-A Evaporator is fundamental to the Hanford Site tank waste mission and will play an essential part in the DFLAW treatment approach, according to the DOE.

Uncertainties with WTP persist, GAO says

The Department of Energy’s Office of Environmental Management has not followed best practices or DOE policy in pursuing alternatives for pretreating radioactive tank waste at the Hanford Site, near Richland, Wash., according to a report released on May 12 by the Government Accountability Office. The DOE has spent over $400 million since 2013 looking into alternatives to pretreating Hanford’s low-activity waste (LAW), yet the department has not properly defined a mission need or a life-cycle cost estimate for its preferred alternative, according to the report.

The startup of tank waste treatment activities at Hanford’s Waste Treatment and Immobilization Plant took a step forward in April with the Department of Energy’s issuing a request for information for the operation of the WTP Direct Feed Low-Activity Waste (DFLAW) facilities. According to the DOE, the RFI solicits input, via capability statements, from potential contractors with the specialized capabilities necessary to meet all of the major elements of scope for the upcoming competitive procurement for the operation of WTP DFLAW facilities, which will treat and vitrify for disposal low-activity waste from underground storage tanks at the Hanford Site near Richland, Wash.
