Room-temperature tensile properties are given for a series of slip-cast APPR-type UO/sub 2/ stainless steel fuel plates. Properties of conventionally fabricated tupe SM-1 dispersion plates were determined for comparison. Slip-cast fuel plates sintered to 90% density, hot or cold rolled approximately 30%, and annealed 1 hour at 1120 deg C showed ultimate tensile strengths equal to those of the conventional plates, slightly lower yield strengths, and tripled ductility. All of the slip cast plates, in the annealed condition, and all of the conventional plates withstood 90 deg cold bends around a sharp-edged punch (0 deg radius) without visible cracking. An in vestigation of the basic variables involved in the slip casting process was started. Techniques for measuring slip stability and castability were evolved and preliminary tests were made. Tests were also started to determine the effect of particle size distribution on the green and sintcred densities of siip castings. (auth)
