Description

In the ACP(the Advanced Spent Fuel Conditioning Process), UO2 pellet is converted into U3O8 powder since U3O8 powder is much desirable form for the following metallization process. The 20 kgUHM/batch size voloxidizer is under development in KAERI. Prior to the bulky and tricky 20 kg batch experiment, we tried to find the optimal condition of air flow rate and O2 concentration, which provides the maximum oxidation rate and prevents scattering of the fine U3O8 powder in the reactor caused by the excessive air flow rate, by using the small sized oxidation reactor. This reactor is similar in structure with the full sized one. Also the particle size of oxidized U3O8 powder was measured using the particle size analyzer
