Jet pump beam holder/positioner tool

This patent describes a nuclear reactor having a jet pump diffuser and a pressure sensing line and a stand off block, a beam for securing a pressure sensing line to the side of a jet pump diffuser, comprising in combination: an arcuate beam member having an upper and a lower end and spanning a length sufficient to provide two spaced apart points of support for the line from the diffuser; the beam defining at the points of support a line receiving concavity for locating the line relative to and generally parallel to the length of the arcuate beam; one of the ends of the beam opening to the side to receive the line between the line receiving concavity and wall of the beam opposite the line receiving concavity; the wall of the beam opposite the line receiving concavity defining an opening for receiving the stand off block adjacent the line. The line can be captured to the stand off block in registration with the stand off block; the other end of the beam having an introduced stand off block; means for securing the introduced stand off block for towards and away movement from the beam. The security means permits the introduced stand off block and beam to open to the side to receive the line. The introduced stand off block can move away from the beam to receive the line and towards the beam when the beam is drawn over the line. This action traps the line in spaced apart relation from the walls of the diffuser
