METHOD TO MANUFACTURE FUEL RODS WITH ZIRCONIUM SHELL Russian patent published in 2013 - IPC G21C21/00 

FIELD: power engineering.

SUBSTANCE: method may be used to manufacture fuel elements of nuclear reactors with cermet fuel rods. The unit of fuel rod stocks is placed in a container above briquettes of working medium from glass, the container is closed with a cap, the container is put into a through furnace, and the cap is removed at the outlet of the furnace after submersion of the unit into the working medium. To prevent exhaust of the working medium into the volume of the cap, a layer of more fusible glass is arranged on the surface of briquettes in comparison with the glass of briquettes, for instance, in the form of powder.

EFFECT: reduced adhesion of glass to stocks and easier release of stocks from glass after their pressing due to limitation of through furnace atmosphere access to surfaces of stocks in process of their submersion.
