Abstract Scope |
Chlorine Induced Stress Corrosion Cracking (CISCC) is a concern for dry storage canisters around the coastal United States. A mechanistic understanding of the process could help predict crack growth rates. In situ synchrotron x-ray tomography and diffraction were performed on different heats of 304SS (representing spent fuel canister material) during chlorine induced stress corrosion cracking in a simulated marine environment. The role of martensite was probed using x-ray diffraction data while the role of crack branching was studied using the x-ray tomography data. Additionally, the role of stress intensity was probed using both x-ray tomography and stress intensity analysis. Post experimental electron microscopy was used to determine the chemical and structural compounds formed around the crack. A mechanism based on the experimental evidence of atmospheric chlorine induced stress corrosion cracking was then proposed. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525. |
