PURPOSE: An assembly of zirconium alloy guide pipe and stainless steel interior connection pipe of a nuclear fuel assembly is provided to connect a guide pipe and an interior connection pipe through a filler metal, thereby shortening the assembling time of guide pipe and interior connection pipe. CONSTITUTION: An injection hole (111) is formed penetrating in the outer periphery of a guide pipe flange. The surface of an interior connection pipe (120) is exposed by the injection hole. The bottom end of the interior connection pipe is inserted into the guide pipe flange. The bottom end of the interior connection pipe is injected through the injection hole. The guide pipe and interior connection pipe are fixed by a filler metal.
