摘要： The invention relates to a method for installing a rail apparatus and a rail apparatus for running an automatic ultrasonic flaw detector around a reactor pressure vessel (1) for detecting any flaw in the weld beads (12, 13) on the reactor pressure vessel. At least two circumferential rails (221-224) and vertical rails (231-234) are connected through turn tables (241-244) at their crossing points to form a rail unit. The rail unit has vertical rails (231, 233) extending upward from the uppermost circumferential rail. The vertical rails are secured to a gamma shield (20) so that the rail unit as a whole is suspended from the gamma shield (20) by means of these vertical rails. The rail unit is provided with swing prevention devices (28) for preventing swing thereof. In installation of the rail apparatus, the rail unit is temporarily mounted to the reactor pressure vessel before mounting the latter into a containment vessel. Then after placing the reactor pressure vessel together with the rail unit in a right place within the containment vessel, the rail unit is supported suitably by the gamma shield.

摘要： On the basis of a finding that a magnetic hysteresis of a metal material, among magnetization characteristics changing with secular embrittlement of the metal material, shows a clear correspondence with the degree of embrittlement of the metal material, a change in such a magnetization characteristic is measured to estimate the degree of secular embrittlement of the metal material. In a typical embodiment, a superconducting quantum interference device (340) is used to detect the magnetization characteristic of a measuring object (11). According to the present invention, the degree of embrittlement of a metal material used in an environment of high temperatures can be quickly detected in a non-destructive fashion so that the danger of brittle fracture of the metal material can be reliably prevented.

摘要： A guide apparatus comprises annular rail means (24) and means (27, 28, 29) for attaching the annular rail means onto a cylindrical member (19) to be inspected by a inspecting means on the rail means. The attaching means is provided on the rail means and includes at least two radially stationary jaw means (28, 29) and at least one radially movable jaw means (27). Each of the radially stationary jaw means has a jaw surface to be abutted on an outer pe, iphery of the cylindrical member. A radial distance between the abutting surface of the radially stationary jaw means and the inner peripheral surface of the radial means is discontinuously variable.
