The sodium compatibility and the nitric acid dissolution of (Zr(0.80)U(0.20)N, prepared by carbothermic reduction of the oxide, were determined. No interaction with liquid sodium (T=823 K) was observed. The material readily dissolved in nitric acid (T=378-383 K). From these results it is concluded that ZrN is an attractive inert matrix in fast reactor fuels for the incineration of plutonium and minor actinides.
