METHOD FOR CERAMIC SOLID NUCLEAR FUEL PRODUCTION AND DEVICE FOR ITS REALIZATION Russian patent published in 2005 - IPC

Abstract RU 2258964 C2

FIELD: nuclear industry; ceramic nuclear fuel production.

SUBSTANCE: the proposed method of ceramic nuclear fuel production includes fuel dispersion by means of oxidation with air flows, fed under the layer of heated fuel. The fuel oxidation is carried out when feeding two air flows, one of which is stopped during vibration release of obtained products of dispersion. The vibration release of dispersion products from the fuel layers is realized periodically with extraction of fine-dispersed powder. The device for ceramic nuclear fuel production includes vertical tubular multistage vibroreactor with the cascade of sieve grids and powder separator. The sieve grids are disposed one over another and equipped with poured tubes.

EFFECT: enhanced quality of ceramic nuclear fuel production.
