Symposium Composite Materials for Nuclear Applications II
Presentation Title Mechanistic Understanding of Hydrothermal Corrosion of SiC Under Irradiation
Author(s) Peng Wang, Gary S Was
On-Site Speaker (Planned) Peng Wang
Abstract Scope SiC-SiC composite materials are of growing interest for accident tolerant fuel cladding applications due to their excellent physical and mechanical properties that are desirable for high-temperature environments and under intense radiation conditions. However, under normal operation conditions, hydrothermal corrosion of SiC has been a concern in the light water reactor environment where continuous dissolution of SiC into the water was accelerated under the influence of water radiolysis and irradiation. An in-situ irradiation-corrosion experiment on 3C-SiC using proton beam has demonstrated that hydrothermal corrosion of SiC in high-temperature water depends strongly on both the corrosion potential and irradiation. Corrosion of SiC in water was also studied using ab initio molecular dynamic (AIMD) to elucidate the atomic-scale corrosion mechanism.
