FIELD: physics.
SUBSTANCE: apparatus for foiling fuel element cladding has a foil, rollers for rolling the foil, a die, a bar with a cylinder whose diameter is equal to the diameter of pellets of fissile material, sponges surrounding the cylinder in front of a slide valve. The slide valve is spring-loaded in guides from two pipe sections with slits which restrict its movement, wherein the guides are placed at the end of the fuel element cladding, which is placed in a lodgement. On the plane of the slide valve, there are protrusions which form a radial flange of the foil at the end of the cylinder.
EFFECT: high quality of the radial flange of the foil.
