Creators

Description

An improved method of preparing nuclear reactor fuel by carbonizing a uranium loaded cation exchange resin provided by contacting a H+ loaded resin with a uranyl nitrate solution deficient in nitrate, comprises providing the nitrate deficient solution by a method comprising the steps of reacting in a reaction zone maintained between about 145 to 2000C, a first aqueous component comprising a uranyl nitrate solution having a boiling point of at least 1450C with a second aqueous component to provide a gaseous phase containing HNO3 and a reaction product comprising an aqueous uranyl nitrate solution deficient in nitrate
