1. A core spray sparger T-box clamp assembly for a sparger T-box in a nuclear reactor, the clamp assembly comprising:an anchor plate shaped to substantially align with a cover plate of the T-box;a clamp including a plurality of latches mated with the anchor plate, the clamp configured to connect and secure the anchor plate to the T-box via the latches the latches being directly connected to the t-box;at least one sparger pipe support configured to attach to sparger pipe adjoining the T-box, the sparger pipe rigidly connected to the anchor plate in at least one dimension; anda bearing plate extendably attached to the anchor plate, the bearing plate configured to seat against the cover plate of the T-box. 2. The clamp assembly of claim 1, wherein the clamp further includes a rotatable extension on a front face of the clamp assembly, the rotatable extension configured to tighten the clamp against the T-box via the latches when the rotatable extension is rotated. 3. The clamp assembly of claim 2, wherein the rotatable extension includes a ratchet nut, a ratchet nut lock, a slider wedge, and a central post. 4. The clamp assembly of claim 3, wherein the central post extends concentrically through the anchor plate, the ratchet nut, the ratchet nut lock, and the slider wedge, and wherein the slider wedge is nested within the ratchet nut and the ratchet nut is nested within the ratchet nut lock. 5. The clamp assembly of claim 3, wherein the ratchet nut lock is rigidly connected to the slider wedge, and wherein the ratchet nut lock engages the ratchet nut so as to permit rotation of the ratchet nut only in a single direction. 6. The clamp assembly of claim 1, wherein the latches engage opposite sides of the T-box and center the clamp and anchor plate between the opposite sides. 7. The clamp assembly of claim 1, wherein the anchor plate and the sparger pipe support are rigidly connected in only two perpendicular directions. 8. The clamp assembly of claim 7, wherein the anchor plate and the sparger pipe support are connected by a dovetail joint. 9. The clamp assembly of claim 1, wherein the sparger pipe support includes at least one T-bolt, at least one T-bolt nut, and at least one sealing collar. 10. The clamp assembly of claim 9, wherein the sparger pipe support is connected to the sparger pipe by the T-bolt, the T-bolt nut, and the sealing collar, the T-bolt extending through the sparger pipe support and into the sparger pipe. 11. The clamp assembly of claim 10, wherein the T-bolt nut is configured to be tightened from a front face of the clamp assembly. 12. A core spray sparger T-box clamp assembly for a sparger T-box in a nuclear reactor, the clamp assembly comprising:an anchor plate shaped to substantially align with a cover plate of the T-box;at least one sparger pipe support attached to sparger pipe adjoining the T-box, the sparger pipe rigidly connected to the anchor plate in at least one dimension;a bearing plate extendably attached to the anchor plate, the bearing plate, the plurality of latches directly connected to the t-box and configured to slide radially inward toward the anchor plate; anda clamp including a plurality of latches extending around the anchor plate and the bearing plate, the plurality of latches configured to slide radially inward toward the anchor plate as the clamp is tightened. 13. The clamp assembly of claim 12, wherein the anchor plate, the sparger pipe support, and the bearing plate are configured to be attached to or removed from one of the sparger T-box and the sparger pipes through a single face of the clamp assembly. 14. A core spray sparger T-box clamp assembly for a sparger T-box in a nuclear reactor, the clamp assembly comprising:an anchor plate;at least one sparger pipe support configured to attach to a sparger pipe adjoining the T-box, the sparger pipe support connected to the anchor plate;a bearing plate extendably attached to the anchor plate; anda clamp including a plurality of latches configured to engage directly with the T-box, the clamp urging the bearing plate against a cover plate of the T-box, the clamp being secured to the T-box by the latches so as to provide the urging. 15. The clamp assembly of claim 14, wherein the clamp includes a rotatable extension configured to tighten the clamp and further urge the bearing plate against the T-box. 16. The clamp assembly of claim 15, wherein the rotatable extension includes a ratchet nut, a ratchet nut lock, a slider wedge, and a central post. 17. The clamp assembly of claim 16, wherein the central post extends concentrically through the anchor plate, the ratchet nut, the ratchet nut lock, and the slider wedge, and wherein the slider wedge is nested within the ratchet nut and the ratchet nut is nested within the ratchet nut lock. 18. The clamp assembly of claim 16, wherein the ratchet nut lock is rigidly connected to the slider wedge, and wherein the ratchet nut lock engages the ratchet nut so as to permit rotation of the ratchet nut only in a single direction. 19. The clamp assembly of claim 14, wherein the latches extend around an outer edge of the anchor plate at equal and opposite intervals so as to engage opposite sides of the T-box. 20. The clamp assembly of claim 14, wherein the anchor plate and the sparger pipe support are rigidly connected in only two perpendicular directions.
