Abstract
As part of research 011 the vibratory compaction method of fabricating U02 fuel elements, the effect of vibration character (frequency, acceleration and so on) on the compaction density was studied with sinusoidal wave vibration generated by an electrodynamic-shaker, with the view to optimization of vibration conditions for obtaining high compaction densities. Fused UO2 with a particle size distribution of −6, +12 mesh: 67.5w/o, −40, +70 mesh: 20.0w/o, −200 mesh: 12.5w/o (mesh: US. Unit) was compacted into 40 “long, 0.5” outer diameter and 0.035 wall 304 stainless steel tubes. Optimum results (88% of theoretical density) were obtained with the following stepwise acceleration increase procedure:Keywords
