The support clamp assembly of claim 10, further comprising:a dowel pin on an inner surface of the recessed area of the pad,the jack screw defining a divot on a side surface of the jack screw near the distal end of the jack screw, the divot matable with the dowel pin to lock the jack screw and the pad in place within the corresponding support groove. 12. The support clamp assembly of claim 10, further comprising:serrated edges on a circumferential surface of the jack screw,a ratchet lock spring on the front surface of the housing, the ratchet lock spring engageable with the serrated edges of the jack screw to incrementally tighten the jack screw and provide anti-rotational support for the jack screw. 13. The support clamp assembly of claim 12, wherein the jack screw and the ratchet lock spring are made of a material configured to substantially maintain its physical properties in an operating nuclear reactor environment, wherein the jack screw and ratchet lock spring are made from a material that is different from a material of the housing, the jack screw and ratchet lock spring being made from Iconel X-750, a nickel-chromium-iron alloy. 14. The support clamp assembly of claim 1, wherein, the housing is made of a material configured to substantially maintain its physical properties in an operating nuclear reactor environment, the housing material being type 316 austenitic stainless steel. 15. The support clamp assembly of claim 1, further comprising:opposing, vertically extending tongues attached to the main body of the housing, the tongues configured to insert into grooves on a side surface of the fingers to attach the housing to the fingers without welding,wherein the longitudinal rear surface of the main body is about perpendicular to the horizontally extending fingers, the tongues extending about parallel to a longitudinal length of the main body. 16. A support clamp assembly, comprising:a jet pump sensing line support configured to be affixed to a jet pump diffuser,a plurality of horizontally extending fingers projecting from the jet pump sensing line support, the fingers located in a vertical row, each pair of fingers defining a support groove between the pair of fingers,jet pump sensing lines configured to be located in each support groove,a housing with a longitudinal rear surface attachable to a distal end of the plurality of fingers without welding,a plurality of access holes in a row defined by the housing, the row of access holes positioned lengthwise along the housing, each hole located in front of a support groove, an axial centerline of each hole being about collinear with an axial centerline of a corresponding support groove. 17. The support clamp assembly of claim 16, further comprising:a pad located in each support groove, each pad having an arced rear surface that mates with a corresponding sensing line. 18. The support clamp assembly of claim 17, wherein each the pad has a recessed area on a front side of the pad. 19. The support clamp assembly of claim 18, further comprising:a jack screw in each of the access holes, each jack screw having a distal end fitting within the recessed area of a corresponding pad, the jack screw configured to be tightened to ensure that the corresponding pad fits snugly against the sensing line. 20. The support clamp assembly of claim 19, further comprising:a dowel pin on an inner surface of the recessed area of each pad,each jack screw defining a divot on a side surface of the jack screw near the distal end of the jack screw, the divot mating with the dowel pin to lock the jack screw and the pad in place within the corresponding support groove. 21. The support clamp assembly of claim 19, further comprising:serrated edges on a circumferential surface of each of the jack screws,a ratchet lock spring, for each jack screw, located on the front surface of the housing, each ratchet lock spring engaging the serrated edges of a corresponding jack screw to incrementally tighten the jack screw and provide anti-rotational support for the jack screw. 22.
