| Abstract: | The surface reaction of uranium-niobium alloy with c arbon monoxide has been studied by x-ray photoelectron spectroscopy(XPS) and gas chromatography(GC).The reaction leads to the formation of UO2,UC/UCxO y,Nb2O5 and NbO on the surface of uranium-niobium alloy after exposure i n the atmosphere of carbon monoxide for 72 hours at 25℃.In the meanwhile CO2 has clearly been detected in the atmosphere after the reactions.The interaction mechanism of uranium-niobium alloy with carbon monoxide has been also discussed. |

| Keywords: | uranium-niobium alloy carbon monoxide x-ray photoelectron spectroscopy |
