| Abstract Scope |
The reactor core is a multi-component extreme environment in which materials must operate. When combined, various stressors on core materials (temperature, stress, chemical, irradiation) produce degradation rates and modes that are not simply additive nor predictable. The effects of simultaneous irradiation and corrosion are also not separable (e.g. post-irradiation corrosion tests) and also provide an excellent example of the variability in material response with environment. For example, in high temperature water, corrosion of Zircaloy is greatly accelerated under irradiation with corrosion rates increasing steeply with flux, while corrosion of stainless steel under irradiation is suppressed. Corrosion of SiC depends strongly on the fabrication process and on both the corrosion potential and irradiation. The nature of irradiation-corrosion interaction in various systems will be discussed along with proposed processes to explain some of the seemingly contradictory observations. |
