NEUP CINR-20-19195: The effect of LWR primary coolant water chemistry (LiOH vs. KOH) on stainless steel: An integrated experimental and computational study of the corrosion response of stainless steel for different surface microstructures and mechanical stress factors

The primary objective of the proposed research project is to study the effect of surface microstructure, mechanical stress factors, and dpa damage on the corrosion response of stainless steel under two different alkaline PWR water chemistry conditions. We will investigate mechanical stress factors such as strain rate, residual stress, deformation induced persistent slip bands (PSBs), dpa damage, and fatigue cracks. This work will inform the US nuclear industry regarding KOH.
