Glass/Metal Interactions, Leaching, Waste Glass, Canister Material

摘要

A series of glass/metal leaching experiments have been conducted to evaluate the effects of potential metal canister and metal overpack materials on the durability of SRP waste glass. A modified leaching test, based upon standard MCC-1 leaching procedures, was used. The metals studied included: low carbon steel, ferritic steel, austenitic steel, a titanium based alloy, lead, Inconel 600, and E-Brite. The simulated SRP waste glass system studied was 131/TDS waste glass, a glass system with the most extensive data base available. At the conclusion of the test, leachate samples were analyzed for key elements in solution, and the surfaces of the metal and glass samples were examined for microstructural changes. 15 figs., 4 tabs.
