More Information
Summary:FIELD: nuclear power engineering; structural components of nuclear reactor fuel assemblies. ^ SUBSTANCE: proposed guide channel has stepped sleeve around tube that has annular drilling on inner surface accommodating bushing welded to sleeve. At least end of bushing providing power contact between sleeve and tube and end of tube are butt-to-butt assembled with mating surfaces of sleeve and the latter is made of metal similar to that of fuel assembly top nozzle. Sleeve can be longitudinally split, built of two parts, or provided with axial slits and welded to outer surface of tube to join its slits. ^ EFFECT: provision for nonsplit joint between channel and top nozzle made of different non-welding metals. ^ 3 cl, 3 dwg
