The preparation of uranium (IV) oxide (UO2) and mixed actinide oxides containing UO2 can be accomplished by heating actinide compounds in the presence of hydrogen. Hydrogen is required as a reducing agent to prevent the oxidation of U(IV) to a higher oxidation state. The capability to heat actinide materials in a reducing environment using 2.9 volume % hydrogen in Ar was installed in glovebox 46 in lab C-155. Multiple research and demonstration programs will utilize the furnace capability to prepare actinide oxides.
