| Abstract Scope |
Structural materials used in the pressure vessels of nuclear reactors face extreme conditions, including high temperatures, radiation, mechanical stresses, and corrosive environments characterized by corrosion, radiolysis, and hydriding. Addressing these challenges is essential to extending the lifespan of current Light Water Reactors (LWRs) and successfully deploying Generation IV reactor concepts. In this presentation, we will examine the real-time monitoring of model metal alloys exposed to corrosive environments using advanced synchrotron X-ray imaging techniques. Our approach utilizes synchrotron X-rays as both an imaging probe and a controlled source of non-displacive radiation. This allows for simultaneous investigation of microstructural changes under combined corrosion and radiolytic conditions. This approach provides new insights into the dynamic degradation mechanisms involved and contributes to the development of radiation-tolerant structural materials for nuclear energy applications. |
