... These canisters are to be stored at the site until a permanent geological repository is opened and ready to receive them. Extended Slu(lge Processing Extended sludge processing is being used to prepare the sludge portion of the tank waste for processing into glass.

... The process removed cesium from the salt solution, but it also resulted in the generation of flammable benzene from radiolytic reactions and possibly from catalytic reactions with trace metals in the waste. In September 1995, SRS initiated ITP processing operations in a tank that contained about I.7 million liters (450,000 gallons)

From page 21...
... Crystalline Silicotitanate Ion Exchange Ion exchange has been in commercial use for over ~ 00 years to remove ions from aqueous solutions, e.g., to make deionized water. In most applications the separated ions are elated from the ion exchange material, e.g., using a dilute acid, the eluted ions are concentrated, and the ion exchanger is reused over and over.

... Solvent extraction has had a long history of successful use in the nuclear industry for such operations as spent fuel reprocessing and plutonium recovery. This history includes long periods of time in which solvents of various organic species have been exposed to high-radiation fields without experiencing catastrophic degradation rates.
