The invention relates to nuclear engineering. The inventive method for producing ceramic nuclear fuel tablets consists in preparing, granulating and pressing a moulding powder and in sintering the thus obtained tablets. The preparation stage consisting in grinding and mixing is carried out by means of ferromagnetic needles in a container under magnetic field action. The inventive device for preparing the moulding powder comprises a protective chamber, a grinding and mixing unit embodied in the form of an inductor coil. A tube which is made of a non-magnetic material and in which the container is arranged is introduced into the inductor coil. Said device also comprises a powder granulation unit, a container conveying and positioning system provided with elements for vertically displacing and turning said container. The protective chamber is embodied in the form of a circuit in such a way that the container is displaceable therein. Said container is made of a non-magnetic material in the form of a cylinder and provided on the end surface thereof with a valve which is connected to a cylindrical tank by means of a flange joint. The valve has an internal cavity which is separated from the cylindrical tank by a transversal mesh partition impenetrable for the ferromagnetic needles. Said invention is characterised in that it improves the powder mixing efficiency. |
