Bruce GS A Calandria Tube Removal 2A-28 Tooling and Bulkhead Welding Tool

Abstract

A longitudinal crack in the full length of the calandria tube (c/T) at Bruce A Unit 2, channel N06, prevented the ase of conventional tooling, ie expan- ding bung, for removal purposes. One alternative method was a welding tool developed by GE Canada to weld a bulkhead radially into the calandria tube which could then be used for pushing or pulling the C/T out of the reactor using a separate push/pull tool. This presentation describes the design and development of the bulkhead welding tool.
