Uranium nitride has a high U density that is an important property for the accident tolerant fully ceramic microencapsulated fuel design. Gadolinium is burnable poison important for flattening the reactivity of the fuel. The impact of the chemical form of Gd additions to the sol-gel feedstock was investigated in this work. Densities were higher when Gd was incorporated as a nitrate hexahydrate and lower when added as a sesquioxide.
