  • Method for repairing vertical welds in a boiling water reactor shroud using a clamp with eccentric pins sealed against an interior of the shroud
    Patent number: 6178635
    Abstract: A method of repairing a crack in a boiling water reactor shroud with a clamp having pins eccentrically mounted on disks connected by a structural member includes inserting the pins into openings formed in the shroud on opposite sides of the weld and turning the disks to rotate the pins toward the weld such that edges of the holes are engaged by the pins to transmit loads from the shroud to the structural member rather than the weld. A seal member is mounted in compression between a flange at an inboard end of at least one of the pins and an inner surface of the shroud to control leakage through the opening in the shroud.
