Abstract
PURPOSE:To surely install a reactor instrumentation pipe in a simple structure and prevent its bond by providing its pressure welding part made of shape memory alloy. CONSTITUTION:A cylindrical base part 25a, a plurality of arm parts 25b composed of shape memory alloy projected from its end and a tubular part as a pressure welding part 25 at which a roller 25c and the like on the edge thereof are provided on the upper end of an instrumentation pipe body 24 and the pressure welding part 25 is abutted on an upper grid plate 26 which is a core support plate 27. At the lower end of the instrumentation pipe body 24 a taper part 31 is closely spaced on a seat 30 of an in-core housing 28 and an in-core flange 29 through a reactor core support plate 27. Therefore, since the arm part is widened at the high temperature of nuclear reactor operation and shunk at the low temperature of the nuclear reactor stop, it is a simple formation and can surely be installed into a reactor core. Further, the reactor core instrumentation pipe 23 can be prevented from being bonded on the upper grid plate 26.
