| Abstract Scope |
Both current and advanced reactors require that materials operate in extreme environments consisting of high temperature, irradiation, stress, and chemical aggressiveness. Depending on the reactor design and degradation mode, different combinations of these environmental components come into play. Swelling is of greatest concern in sodium cooled reactors and the primary environmental components are temperature and damage. Irradiation creep is of concern in both LWRs as well as high temperature concepts with components under stress, in addition to a high temperature and radiation. Finally, irradiation assisted stress corrosion cracking remains a vexing problem in LWRs and requires all of the environmental components to be at work for the process to occur. These degradation modes occur in progressively more complex environments that make for difficult experimentation. This talk will focus on strategies to capture the effect of multi-modal environments on the various degradation modes in an effort to improve our mechanistic understanding. |
