ABSTRACT:
A device (10) for compressing a closure assembly (82) and an O-ring (80) within a control rod drive mechanism for a nuclear reactor in order to seal same. The device (10) applies a predetermined compressive force to the closure assembly (82) and O-ring (80) and has incorporated therein an angularly movable sleeve (18) which engages a lock nut (98) and threadably advances same within the control rod drive mechanism so as to engage the closure assembly (82) and apply the predetermined compressive force to assembly (82) and O-ring (80). After depressurization, lock nut (98) retains closure assembly (82) and O-ring (80) within the control rod drive mechanism by a predetermined residual compressive force.
