Abstract
In an apparatus for producing UOpowder, the apparatus has an oxidation reactor including an interior space, a scrap box loaded with UOsintered pellets to be oxidized and introduced into the interior space of the oxidation reactor, an impact generating unit applying an impact to the scrap box to dissipate heat generated by the oxidation of the UOsintered pellets in the oxidation reactor, and a control unit controlling an oxidation process. The apparatus for producing UOpowder allows the heat generated by the oxidation of the UOsintered pellets in the oxidation reactor to be uniformly dissipated by the impact generating unit, thus producing UOpowder having a larger specific surface area which can be used to obtain a sintered UOpellet with a larger and more stable grain size of increased quality.
