Abstract

Oxide films on austenitic stainless steels in water-cooled nuclear power systems experience redox transients during operational transitions and oxygen ingress events. However, studies on the change of oxide chemistry with time in response to a dissolved oxygen (DO) excursion remain limited. In this study, in-situ Raman spectroscopy is used to track the time-resolved evolution of the 600–750 cm −1 spinel band on as-received and 30% cold-worked 304L stainless steel in high-temperature water (300 °C) under two protocols: (1) a low-DO baseline (DO
