| titleOfInvention | METHOD AND DEVICE FOR PRODUCING FUEL PARTICLES |
| abstract | 1. A method of producing spherical fuel particles and / or particles of a fertile material with a size in the range of preferably from 300 μm to 800 μm, in particular, to obtain particles from uranium oxide and / or uranium carbide and / or uranium-containing mixed oxide and / or mixed carbide, by forming droplets of a solution containing uranyl nitrate as well as at least one excipient such as urea, tetrahydrofuryl alcohol (THFA) and / or polyvinyl alcohol (PVA), into an ammonia precipitation bath (102) to form microspheres, aging and washing of the microspheres obtained in this way in an ammonia solution, drying, and also heat treatment, characterized in that the microspheres (74) are separated from the precipitation bath in the first separator (10) and fed to the aging solution in the ammonia solution for aging, and the duration of contact of the microspheres with the liquid the precipitation bath (102) before being introduced into the aging solution is set equal to or substantially equal, and the microspheres are transferred from the aging solution through a transfer device into a multistage cascade washer (28), in which the microspheres are completely or essentially completely washed off from ammonium nitrate and at least one auxiliary substance contained in the microspheres, and after drying, the microspheres are calcined during heat treatment, being distributed monolayer. 2. The method according to claim 1, characterized in that the same or essentially the same time interval between the formation of microspheres (74) in the precipitation bath (102) and feeding into the aging solution is set by means of the first separator (10). The method according to claim 1 or 2, characterized |
