A radioactive chemical called pertechnetate is a bad actor when it’s in nuclear waste tanks. But researchers at PNNL and the University of South Florida have a new lead on how to selectively separate it from the nuclear waste for treatment.
Installing new access holes (up to 6 feet in diameter) could reduce the overall time and cost to retrieve waste from Hanford's underground storage tanks, according to a structural analysis of the tank domes by PNNL and Becht Engineering.
How might getting old—really old—affect the glass waste form chosen to immobilize radioactive waste at the Hanford Site in southeastern Washington state? Researchers are seeking answers from walls containing ancient glass in Europe. These walls, known as hillforts, are defense structures that date as far back as the Bronze Age. The researchers progress is the cover story in the May 2016 American Ceramic Society Bulletin.
