Abstract
A core spray T-box attachment assembly for a core spray nozzle includes a primary cruciform wedge and a secondary cruciform wedge in contact with the primary cruciform wedge to form a cruciform wedge subassembly adapted for insertion within a bore of the core spray nozzle to sealingly engage an interior converging portion of a safe end of the core spray nozzle. The assembly includes a spider in contact with the cruciform wedge subassembly, and a draw bolt engaging an axial bore of a center portion of the cruciform wedge subassembly and the spider to the T-box.

A method of replacing a subassembly within a core spray nozzle of a nuclear reactor, the subassembly including a T-box and a thermal sleeve, and the core spray nozzle including a safe end with a converging inner surface, the method comprising:
- removing the T-box and the thermal sleeve;
- providing a second T-box and a second thermal sleeve, the second T-box having a first end adjacent the second thermal sleeve;
- assembling a cruciform subassembly in the safe end of the core spray nozzle, the cruciform subassembly configured to create a seal against an inner circumference of the converging inner surface;
- and
- adjusting a clamp attached to a second or third end of the second T-box to seal the cruciform subassembly against the converging inner surface of the safe end of the core spray nozzle.
