Numerous bit styles and designs were tested using core-region mockups containing both actual materials and suitable substitutes in place of radiologically or economically prohibitive materials. The drilling mockup, located at INEL, included composite test samples consisting of Zircaloy-clad quartz rods, Inconel spacer grids, 300-series stainless steel end fittings, concrete blocks, ungraded 3/8-inch gravel, and hard-fired alumina plates. Information obtained from these tests was evaluated to select the drill bit cutter most appropriate for the work at TMI-2. Subsequent proof testing showed the bit to be successful in cutting all the anticipated material configurations | |||
