Abstract Scope |
Decades of experience with operating light water reactors have led to a vast base of knowledge about stress corrosion cracking in LWRs. Improvements in materials and water chemistry have led to fewer operational issues due to environmentally assisted cracking, and thus longer economic lifetimes for LWRs.
Although we have no commercial operating experience with molten salt reactors from which to draw, 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, we 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. We 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. |
