Abstract : During rearrangement of the fuel elements in the SM-1 core, four control rod end caps were damaged because of improper removal procedures. Further unavoidable damage to the end caps occurred in subsequent removal operations. Because of the long lead time necessary to obtain new caps and also because of the large cost involved, it was decided to repair the damaged parts at Ft. Belvoir, Virginia. A water shield tank and remote handling tools were fabricated, the control caps were disassembled, damaged parts were replaced with locally fabricated substitutes, and the reassembled units were put back into service. All work was successfully accomplished without subjecting personnel to dangerous radiation. (Author)
