Initial characterization of the geologic and engineered barrier materials for a nuclear waste repository in basalt has been completed. Data have been obtained on the characteristics of the reference waste forms which are being studied for eventual disposal in such a repository. Reference basalt entablature, colonnade, and flow top specimens have been selected from the Umtanum flow, which is the primary basalt flow under consideration for repository siting. Material from the Mabton Interbed Stratum, Pomona Flow basalt, smectite clay from the Pomona Flow, a potassium clinoptilolite, Beverly sandstone and tuff, and Grande Ronde groundwater are also included in the suite of reference geologic materials. Reference engineered barrier materials include sodium bentonite and canister metals such as carbon steel, cupronickel, Hastelloy and Inconel alloys. Spent fuel, borosilicate glass, and supercalcine ceramic comprise the reference waste forms. Analyses were made for physical, chemical, and morphological characteristics using techniques ranging from simple observations of color to sophisticated ultrastructural analysis in the electron microscope. Analyses of the elemental and phase chemistries for most of the reference materials have been completed on typical samples. Determinations of material homogeneity are currently being performed.
