Abstract:
A spherical fuel element forming apparatus comprises a fuel area forming system, a fuel-free area shaping system and a green sphere pressing system connected sequentially. The fuel area forming system is used for evenly mixing a core sphere matrix powder with nuclear fuel particles and then pressing the mixed core sphere matrix powder and nuclear fuel particles into core spheres. The fuel-free area shaping system is used for preparing a spherical fuel element from the core spheres covered by a fuel-free matrix powder. The green sphere pressing system is used for pressing the spherical fuel elements into green spheres. The spherical fuel element forming apparatus is distributed according to a technical process flow line operation, and is compact in structure and convenient to operate. Sphere greens after being finally pressed are high in sphericity, fuel element cost is lowered, and the finished product rate is high.

Claim (Index 8):
The spherical fuel element forming apparatus of  claim 1 , wherein, the fuel-free area shaping system comprises a core sphere positioning-conveying device ( 9 ), a core sphere positioning-transferring device ( 12 ), a fuel-free area matrix powder quantitative conveying device and a fuel-free area shaping device arranged sequentially; the core sphere positioning-conveying device ( 9 ) being connected with the fuel-free area shaping device through the core sphere positioning-transferring device ( 12 ); the fuel-free area matrix powder quantitative conveying device being connected with the fuel-free area shaping device;\n wherein the core sphere positioning-conveying device ( 9 ) and core sphere positioning-transferring device ( 12 ) are used for transferring the core spheres to the fuel-free area shaping device; the fuel-free area matrix powder quantitative conveying device conveys the matrix powder to the fuel-free area shaping device; the fuel-free area shaping device coats the core spheres with the matrix powder so as to prepare the spherical fuel element.
