OSTI ID:4843271
A pneumatic vibratory compaction machine was designed, constructed, and placed in operation. A study was initiated to determine the feasibility of reaching densities of 90% of theoretical. Eight tubes filled with MgO, used as a substitute for UO/sub 2/, were reduced in cross sections by the Rock Rite process. Initial as-packed density in all specimens was about 65% of theoretical, and final densities ranged from 75 to 90%. Reductions on the various specimens ranged from 20 to 60%. No cladding failures occurred during reduction. Simple welds, one spacer to one rod, were successful in that welds can be made which penetrate only about 50% of the clad wall. Work hardened tubing was subjected to 700 deg F steam for periods up to 123 days. Tensile testing of the specimens showed that no annealing occurred. (auth)
