Solid forms for Savannah River Plant radioactive wastes
Methods are being developed to immobilize Savannah River Plant wastes in solid forms such as cement, asphalt, or glass. /sup 137/Cs and /sup 90/Sr are the major biological hazards and heat producers in the alkaline wastes produced at SRP. In the conceptual process being studied, /sup 137/Cs removed from alkaline supernates, together with insoluble sludges that contain /sup 90/Sr, will be incorporated into solid forms of high integrity and low volume suitable for storage in a retrievable surface storage facility for about 100 years, and for eventual shipment to an off-site repository. Mineralization of /sup 137/Cs, or its fixation on zeolite prior to incorporation into solid forms, is also being studied. Economic analyses to reduce costs and fault-tree analyses to minimize risks are being conducted. Methods are being studied for removal of sludge from (and final decontamination of) waste tanks.
