<P>PROBLEM TO BE SOLVED: To provide a fixing device for reducing stress induced in a welded section of a metering pipe by fixing a reactor metering pipe to the outer circumference of a circular tube of a jet pump diffuser. <P>SOLUTION: An outer member 41 is supported to the outer circumference 18a of the circular tube of the jet pump diffuser 18 by a C-shaped support member 30, and the metering pipe 19 is clamped in the radial direction by the outer member 41 and inner member 42, 43. Wedge members 44, 45 are interposed between the outer circumference 18a of the circular tube and inner members 42, 43 to firmly fix the metering pipe 19 to the outer circumference 18a of the circular tube. <P>COPYRIGHT: (C)2009,JPO&INPIT |
