DOE Expects To Start ‘Vitrifying’ Hanford Nuclear Waste Next Year
In 2023 the Division of Power will start reworking the poisonous soup saved in tanks on the Hanford, Wash. nuclear waste web site right into a extra storable glass kind, in accordance with the pinnacle of DOE’s Workplace of Environmental Administration.
“We’re about to start heating up the primary WTP melter,” stated administrator Ike White in a current look on the Nationwide Cleanup Workshop. The Waste Remedy Plant melter is designed to warmth nuclear waste and glass to 2,100º F so the combination might be poured into chrome steel containers in a stabilizing course of referred to as “vitrification.” The containers will likely be saved on web site.
Turning on the primary melter topped the to-do listing launched early this 12 months by DOE’s Workplace of Environmental Administration, and with the New 12 months approaching, time is operating out to examine it off.
“That is one other enormous step ahead for this system as Hanford will get ever nearer to immobilizing our tank waste in glass,” White stated. “It is actually transformational for a web site that— and it has been a long time in coming.”
The melter DOE hopes to activate by the top of 2022—and to function for a five-year lifetime—was put in 12 years in the past.
A graphic roadmap printed by the cleanup contractor, Bechtel Nationwide Inc, suggests—maybe with out irony—that the highway forward is the steepest but. Bechtel and DOE nonetheless anticipate to start the operations section, feeding low-level waste into the “vit plant” by December 2023.
The highway so far has not been with out bumps. DOE expressed frustration with Bechtel’s progress greater than a decade in the past, with one official calling the agency “incompetent” and urging it’s faraway from the job. Simply final 12 months, former Power Secretary Steven Chu accused Bechtel and different federal contractors of opposing funding for analysis into higher options for nuclear waste so they might proceed to gather large funds from the federal government 12 months after 12 months.
White expressed a extra constructive view:
“All people is on the identical web page with the imaginative and prescient for getting the cleanup carried out, growing a sensible and achievable method for our most tough challenges, just like the high-level tank waste at Hanford,” he stated.
DOE started treating some low-level waste at Hanford in 2022, and the vitrification course of scheduled to start out subsequent 12 months will even deal with low-level waste. Excessive-level waste is one other matter.
“We’re treating Hanford tank waste on a big scale for the primary time ever,” White stated. “However growing a sensible and achievable method for addressing the complete stock of waste there stays a hurdle, one thing that we should overcome.”
Starting within the Nineteen Forties, the tanks at Hanford acquired wastes from processes used to extract plutonium from spent nuclear gas to be used in nuclear weapons. The tanks continued to obtain waste from gear decontamination on the Hanford web site into the Sixties, and within the Seventies it was found that some tanks appeared to be leaking.
