Reduced activation ferritic steel F82H is a prime candidate for the Japan’s DEMO reactor blanket structural material. In this study, surface oxidation treatments for F82H have been performed to evaluate the effect of the chromium oxide layer on deuterium permeation and its stability under actual DEMO reactor conditions.
