Abstract
An apparatus () for thermal denitration of a uranyl nitrate hydrate to uranium trioxide UO3. The apparatus () comprises a burner () and a reaction chamber () configured to carry out thermal denitration of uranyl nitrate hydrate and to form uranium trioxide UO3 in the form of particles. The apparatus also comprises a separating chamber () suitable for separating UO3 particles from the gases resulting from the thermal denitration carried out in the reaction chamber (), and at least one filter () configured for purifying the gases. The separating chamber () is a decanting chamber into which the reaction chamber () directly opens out. The filter () is capable of performing the separation at a temperature greater than or equal to 350° C. The invention also relates to use of such an apparatus, to a thermal denitration process and to UO3 particles obtained by such a process.
