Specimens cut from series of glasses made at PNNL to represent a range of salt loadings in prototype composition DPF-5 and a range of iron oxide loadings in prototype composition DPF-3 were subjected to modified ASTM C1308 tests to assess the relative durabilities and retention of salt cations. Test results show both the intrinsic durability and salt cation retention decrease as the total amount of salt cations is increased, but waste forms made with up to 34 mass % salt waste loadings on a salt-cation basis are more durable than glass-bonded sodalite waste forms made with optimal salt waste loadings (about 6% on a salt-cation basis). Other tests are in progress to assess the effect of solution feedback on the long-term durability of these materials.
