| Abstract Scope |
New technical advances in drilling technology have advanced the possibility of using very deep boreholes (3-5 km) into the crystalline basement rock for disposal of the nuclear waste. The design of the canister used to hold the nuclear waste is one of the primary engineered barriers in the design of geologic disposal systems. There is a need for novel canister designs and materials that can withstand the different factors that can lead to the degradation of the canister such as general corrosion, localized corrosion, stress corrosion cracking, microbially induced corrosion (MIC), galvanic corrosion, hydrogen embrittlement, and phase stability. Bimetallic structures manufactured via thermal spraying technology for storage canisters were manufactured and tested. Corrosion testing proved the high corrosion resistance and mechanical integrity of novel materials. |
