1. A method to assemble a support clamp assembly in a jet pump of a nuclear reactor vessel, the method comprising:attaching a cable to a first end of a shaft and lowering the shaft and cable into an elbow conduit and thermal sleeve of the jet pump;guiding at least one thermal sleeve anchor device down the cable to slide the anchor device on the shaft, wherein the anchor device abuts against a second end of the shaft;seating the anchor device against an inside surface of the thermal sleeve;extending the shaft from the anchor device, through an aperture in the elbow conduit wherein the aperture is in a wall of the elbow conduit;attaching a securing device to the first end of the shaft extending through the aperture in the elbow conduit, wherein the securing device abuts an outside surface of the wall of the elbow conduit to apply tension to the shaft, andthe tension to the shaft biases the thermal sleeve towards the wall of the elbow conduit. 2. The method of claim 1 further comprising extending the cable through an opening in a riser pipe transition from the jet pump, and inserting the shaft, cable and anchor device through the opening and through an inside of the riser pipe, elbow conduit and thermal sleeve. 3. The method of claim 2 wherein the anchor device includes a primary cruciform and a secondary cruciform, and the method includes sliding the cable through a base in the primary cruciform and then through a base of the secondary cruciform. 4. The method of claim 1 wherein the securing device includes a boss and a nut, and sliding the first end of the shaft through an aperture in the boss and attaching the nut to the first end of the shaft extending through the boss.
