Conclusions
In conclusion, our disposal form development studies determined that:
(1) Hanford WTP waste Ag0Z and other silver mordenites can be
compliantly land disposed if solidified and stabilized using a
formulation of 65 mass% ASTM Portland Type III cement,
25 mass% silver mordenite waste, and 10 mass% CaI2.
(2) CaI2 should be an effective modifier for cements used to
solidify and stabilize any silver sorbents used to control radioiodine releases from nuclear facilities such as nuclear fuel
reprocessing facilities or other nuclear waste vitrification
facilities.
