The results of an analysis of alloy grades for determining the most corrosion resistant material for building a reactor and hydro-fluorination of uranium oxides are presented. The alloy EP-797 or its improved analog EP-797-VI holds the greatest promise for work in a medium consisting of hydrogen fluoride gas and water vapor at temperatures to 600°C. The use of monel in the fluorination of uranium oxides is problematic because of the relatively low application temperature limit ~500°C as well as operating experience gained in foreign conversion plants.
