1. An auxiliary wedge positioning apparatus for use in a nuclear reactor having at least one jet pump assembly, the wedge positioning apparatus consisting essentially of:(a) a restraint bracket body having a top end flat portion having one hole therethrough and a transverse rail with two bottom integral hooked protrusions each exactly opposite to each other and attached to the transverse rail, said protrusions having an angled gull wing shape with an upward member section and a downward member section;(b) a single triangular slide wedge having a flat side attached to the transverse rail of the restraint bracket body, with an end flat portion and an angled side facing outward;(c) a single slide rod passing through the top flat portion hole to contact the end flat portion of the triangular slide wedge; and(d) a single spring disposed around the slide rod, the spring contacting both the top end flat portion and exerting pressure against the end flat portion of the triangular slide wedge to exert pressure against adjacent bodies in the nuclear reactor; wherein the hooked protrusions contain a parallel member section, a middle upward member section and an end downward member section next to the transverse rail, providing an angled gull wing shape, where the parallel member section is outward at a 90° angle from the restraint bracket body, the middle upward member section is at a 20° to 60° angle to the restraint bracket body and the downward member section is at an angle of 70° to 110° from the upward member section and wherein the parallel member section has an attached upward member section ending and a downward member section; wherein the wedge positioning apparatus utilizes a combination of spring force and gravity to continuously tighten over time. 2. The wedge positioning apparatus of claim 1, wherein the hooked protrusions contain a wing angle stabilizing attachment connected to the upward member section and downward member section, where the wing stabilizing attachment is parallel to the upward member section and the downward member section. 3. The wedge positioning apparatus of claim 2, wherein the parallel member section is outward from and attached to the transverse rail, the downward member section is attached to the upward member section which upward section is in turn attached to the parallel member section. 4. The wedge positioning apparatus of claim 1 used for positioning in close contact with a circular jet pump assembly where the gull wing design conforms to the jet pump assembly using a three-line contact to maintain stability between all of the parts, where the hooked protrusions aid in installation of the apparatus while the jet pump assembly is in place and provide stability under vibration conditions, wherein the at least one gull wing is positioned partially around and in contact with the jet pump assembly. 5. In a nuclear reactor, at least two separate auxiliary wedge positioning apparatus, where the nuclear reactor, contains riser piping that can feed pumped cooled water to at least one jet pump assembly having a circumferential restrainer bracket, which restrainer bracket has at least two vibration damping adjustment set screws, each set in a set screw block contacting the jet pump assembly, the bracket positioned around the jet pump assembly which bracket also contacts the riser piping, such assembly and riser piping subject to vibration during reactor operation, wherein a main wedge is utilized away from the set screws, while the at least two separate auxiliary wedge positioning apparatus being positioned adjacent the set screws; wherein the at least two separate auxiliary wedge positioning apparatus consists essentially of:(a) a restraint bracket body having a top end flat portion having one hole therethrough and a transverse rail with two bottom integral hooked protrusions each exactly opposite to each other and attached to the transverse rail, said protrusions having an angled gull wing shape with an upward member section and a downward member section, structured to contact the at least one set screw block;(b) a single triangular slide wedge having a flat side attached to the top rail of the restraint bracket body, with an end flat portion and an angled side facing outward;(c) a single slide rod passing through the top flat portion hole to contact the end flat portion of the triangular slide wedge; and(d) a single spring disposed around the slide rod, the spring contacting the top end flat portion and exerting pressure against the end flat portion of the triangular slide wedge this pressure on the slide wedge forcing it against the jet pump assembly; wherein the hooked protrusions contain a parallel member section, a middle upward member section and an end downward member section next to the transverse rail, providing an angled gull wing shape, where the parallel member section is outward at a 90° angle from the restraint bracket body, the middle upward member section is at a 20° to 60° angle to the restraint bracket body and the downward member section is at an angle of 70° to 110° from the upward member section. 6. The wedge positioning apparatus of claim 5 in use in a nuclear reactor of claim 5, wherein both adjustment set screw blocks contact the hooked protrusion to stabilize it. 7. The wedge positioning apparatus of claim 5 in use in a nuclear reactor of claim 5, wherein the wedge positioning apparatus utilizes a combination of spring force and gravity to continually tighten over time the wedge disposed next to the at least one jet pump assembly. 8. The wedge positioning apparatus of claim 5, wherein the hooked protrusions contain a parallel member section, an upward member section and an end downward member section next to the transverse rail and a wing stabilizing attachment connected to upward member section and downward member section, where the wing stabilizing attachment is parallel to the upward member section and the downward member section and is adjacent to the at least one set screw block, and assists in preventing excessive circumferential movement of the auxiliary wedge positioning apparatus. 9. The wedge positioning apparatus of claim 8, wherein the parallel member section is outward from and attached to the transverse rail, an end downward member section is attached to a middle upward member section which upward section is in turn attached to the parallel member section next to the transverse rail. 10. The wedge pump positioning apparatus of claim 5 used for positioning in close contact with a circular jet pump assembly where the gull wing design conforms to the jet pump assembly using a three-line contact to maintain stability between all of the parts, where the hooked protrusions aid in installation of the apparatus while the jet pump assembly is in place and provide stability under vibration conditions, wherein the at least one gull wing is positioned partially around and in contact with the jet pump assembly and wherein parallel member section a has an attached upward member section ending and a downward member section; wherein the wedge positioning apparatus utilizes a combination of spring force and gravity to continuously tighten over time.
