A FeCrAl-ODS steel has been developed for the accident tolerant fuel cladding of light water reactors in Japanese projects. Spent fuel are reprocessed in Japan, namely spent fuel pins are chopped and immersed into a hot nitric acid solution to leach out the fuel. Behavior of the corrosion products from fuel cladding should be evaluated to estimate the influence of those on the reprocessing process. In this study, effect of nitric acid concentration on corrosion behavior of Fe-12Cr-6Al based oxide dispersion strengthened steels was evaluated.
