| Abstract Scope |
Since discovering that simultaneous irradiation sometimes slows corrosion in molten fluoride salts, researchers are uncovering new and unexpected coupled effects at an accelerating rate. Such coupled experiments are vital, as they are significantly more representative of how materials will behave during reactor operation. In this talk, I present findings related to newly discovered irradiation/corrosion effects, such as: (1) irradiation-induced wetting initiating faster corrosion, yet not accelerating its progression, (2) radiation-induced delocalization which slows corrosion by blurring the line between intragranular and intergranular corrosion, (3) effects of impurities on radiation-affected corrosion, (4) separating radiolysis and radiation-affected corrosion, and (5) radiation-affected dealloying. Our new findings will be tied in with the recent work of many other groups to paint the most complete possible snapshot of how simultaneous irradiation affects corrosion in molten salts and liquid metals, both vital coolants in both advanced fission and fusion nuclear power plants. |
