METHOD OF MAKING REMOTE FUEL ASSEMBLY GRID OF NUCLEAR REACTOR Russian patent published in 2009 - IPC G21C3/34 

FIELD: physics, nuclear physics.

SUBSTANCE: invention relates to atomic energetics and can be used at plants, which make fuel assemblies for energy nuclear reactors. Before stamping of cells, the thickness of the figured cells of a specific melting-batch is determined with the formula. Pressing instruments are selected depending on the size "ready-to-operate" S_M figured cells, size T_M figured cells, equal to the length of the section, corresponding to the size "ready-to-operate", and from the thickness of the walls S figured cells of a specific melting-batch corresponding with the design formula. There is simplification of the process of determining the thickness of the walls of the work piece, increase in the precision of the selection of the press -instrument. Minimum voltage is used when making the fuel assembly.

EFFECT: simplification of the process of determining the thickness of the walls of the work piece, increase in the precision of the selection of the press - instrument, minimisation of voltage used in making the fuel assembly.
