| 摘要 |
The invention concerns a conversion device comprising successively a reactor (12) provided with means for inputting UF6, water vapour and nitrogen for bringing about the formation of UO2F2 by hydrolysis, a rotary pyrohydrolysis tube still designed for transforming UO2F2 into uranium oxide, provided with heating means distributed in at least five zones and means for conditioning the oxide powder. The inputting means comprise an injector with three concentric nozzles respectively connected to intakes of UF6, nitrogen and water vapour, the UF6 being supplied to the central nozzle and the nitrogen being injected between UF6 and water vapour.
