Abstract: The characteristics of UO₂ powder are crucial for production of both UO₂ based fuel and uranium based metallic and alloy fuel. Depending upon the usage as UO₂ based fuel or as metallic uranium based fuel, the desired quality parameters of UO₂ are different. The UO₂ powder was produced by two different methods: (1) by the reduction of the thermal decomposed product of ammonium diuranate and (2) by the direct reduction of ammonium diuranate. Oxygen to uranium ratio (O/U), specific surface area (SSA) and crystal structure of UO₂ powder produced by these two methods were studied.
