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 5):
The spherical fuel element forming apparatus of  claim 2 , wherein, the material canister workstation conveying device ( 6 ) comprises an infrared position sensor, a chain driven by a motor and a plurality of material canisters ( 6 - 2 ) mounted on the chain; wherein the infrared position sensor is used for determining whether the opens of the plurality of material canisters ( 6 - 2 ) correspond to a conveying port ( 6 - 1 ) of the core sphere matrix powder quantitative conveying device ( 1 ), a discharge port of a weighing hopper ( 3 - 2 ) of the nuclear fuel particle accurate quantification device ( 3 ), the primary stirring device ( 4 ) and the discharge molding device ( 5 ) respectively.
