FIELD: nuclear power production, possibly processes for making spacing grids of fuel assemblies assembled of cells formed of tubular blanks. ^ SUBSTANCE: method comprises steps of securing solder in the form of amorphous belt to edges of cells; selecting surface area of solder in the form of amorphous belt secured to edges of cell in range 0.17F -0.61F where F - surface area of cell edge; placing cells in jig for further heating soldered surfaces higher than temperature of solder melting; pressing soldered surfaces one to other with effort in range 300 - 500g/sq.cm. ^ EFFECT: enhanced corrosion proofness and strength of soldered joint, increased rigidity of the whole spacing grid. ^ 4 cl, 1 dwg |
