| titleOfInvention | Method for producing ceramic nuclear fuel tablets, device and container for carrying out said method |
| abstract | 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 ( 7 ) in a container ( 4 ) under magnetic field action. The inventive device for preparing the moulding powder comprises a protective chamber ( 12 ), a grinding and mixing unit embodied in the form of an inductor coil ( 10 ). A tube ( 9 ) which is made of a non-magnetic material and in which the container ( 4 ) is arranged is introduced into the inductor coil ( 10 ). Said device also comprises a powder granulation unit, a container conveying and positioning system provided with elements for vertically displacing ( 8, 13 ) and turning ( 14 ) said container. The protective chamber ( 12 ) is embodied in the form of a circuit in such a way that the container ( 4 ) is displaceable therein. Said container ( 4 ) is made of a non-magnetic material in the form of a cylinder and provided on the end surface thereof with a valve ( 6 ) which is connected to a cylindrical tank ( 21 ) by means of a flange joint ( 25 a , 25 b ). The valve ( 6 ) has an internal cavity which is separated from the cylindrical tank by a transversal mesh partition ( 26 ) impenetrable for the ferromagnetic needles ( 7 ) Said invention is characterised in that it improves the powder mixing efficiency. |
