Post-test evaluations of Waste Isolation Pilot Plant-Savannah River simulated defense HLW canisters and waste form

Eighteen nonradioactive defense high-level waste (DHLW) canisters were emplaced in and subjected to accelerated overtest thermal conditions at the bedded salt Waste Isolation Pilot Plant (WIPP) facility for about three years. Post-test laboratory results of the corrosion and metallurgical property alterations of several stainless steel 304L waste canisters, cast steel overpacks, and associated instrumentation ranged from negligible to moderate. We found appreciable surface corrosion and corrosion products on the cast steel overpacks. Pieces of both 304L and 316 stainless steel test apparatus underwent extensive stress corrosion cracking failure and nonuniform attack. One of the retrieved test packages contained nonradioactive glass waste form from the Savannah River Site. We conducted posttest analyses of this glass to determine the degree of resultant glass fracturing, and whether any respirable fines were present. Linear glass fracture density ranged from about 1 to 8 fractures intersecting every 5 cm (2 inch) segment of the canister cross-section, diameter line. Glass fines between 1 and 10 microns in diameter were detected, but were not quantified.
