Abstract : During rearrangement of the elements in the SM-1 core, (AD-265 580), a control rod basket was damaged so severely that it had to be replaced. The damaged basket assembly was left in the inner shield tank while a safe and practical method of removal could be devised. Several possible solutions to the problem were considered. The method finally selected involved cutting the basket underwater by means of a remote cutter and removing the separate pieces through the fuel transfer chute. This method proved to be effective and the damaged basket was successfully removed without undue difficulty. The basket sections were loaded into a spent fuel cask and shipped to ORNL on 8 May 1961.
