| titleOfInvention | Denitrating apparatus of uranyl nitrate and/or plutonium nitrate |
| abstract | PURPOSE:To prepare uranium trioxide stably, by tilting a rectifying apparatus under a fluidized bed of an apparatus for preparing the uranium trioxide by the thermal decomposition of a solution of uranyl nitrate, and feeding a fluidizing gas of a raw material to a taking out pipe of the uranium trioxide. CONSTITUTION:A tilted rectifying apparatus 3 is provided under a cylindrical body 1 of an apparatus for preparing UO3 by denitrating uranyl nitrate, and a solution (5a) of uranyl nitrate enriched to a given concentration is blown from a feeding pipe 5 to the cylindrical body 1. On the other hand, a fluidizing gas (7a) is blown from a feeding pipe 7 into a wind box 2, passed through the rectifying apparatus 3 and lifted to form a fluidized bed 4. The blown uranyl nitrate is thermally decomposed in the fluidized bed 4 to produce UO3 powder. In this case, coarse particles of the UO3 are lowered along the inner surface of the tilted rectifying apparatus 3, and discharged from a taking out pipe 8. Fine particles (6a) are taken out of an overflow pipe 6 to cause no clogging of the rectifying apparatus 3 and stabilize the operation. The method is applicable to the preparation of plutonium dioxide from plutonium nitrate. |
