| Abstract Scope |
Environmentally assisted cracking was first observed during post-irradiation examination of the Molten Salt Reactor Experiment (MSRE). The observed cracking on the surfaces of salt-facing surfaces was attributed to infiltration of tellurium, a fission product. For future molten salt reactor (MSR) designs, it is important to know if tellurium or other fission products will lead to embrittlement and cracking of materials proposed for salt facing components.
For this talk, I will briefly review the history of environmentally assisted cracking in LWRs and MSRs to see if any lessons from decades of success at mitigating cracking in LWRs can be applied to MSRs. I will then discuss current work on environmentally assisted cracking at Michigan, including studies of irradiation assisted stress corrosion cracking in LWRs, and tellurium assisted cracking in MSRs. I will discuss manufacture and processing of new materials that may mitigate cracking in both LWRs and MSRs. |
