    摘要: The present invention discloses a system for repairing small internal diameter (1.24 in. or less) Inconel 600 bottom mounted nozzles on reactor pressure vessels. The system enlarges the original small diameter nozzle bore to a larger size and ads a larger ID Inconel 600 replacement nozzle therein which allows IDST weld tooling to be inserted to weld the replacement nozzle to thereactor vessel. An Inconel 600 sleeve of the original small ID tubing is inserted in the replacement nozzle and welded to the replacement nozzle to restore the operability of the original tube.
