Abstract
A systematic study has been made on the effect of differences in conditions of applied vibration on the density obtained with a ternary grained powder of arc-fused and crushed UO2 powder packed in a stainless steel cladding tube.
Comprehensive analysis is made of the relationships between densities obtained and vibration conditions, defined by combinations of two factors among four-i.e., frequency, displacement, velocity and acceleration. The highest density has been found to be obtained at the highest acceleration, provided that displacement is in the range of 1030 μm, and this range is found to be the optimum condition for all levels of acceleration.
The process of vibratory compaction is discussed on the basis of the combination of different factors conducive to the compaction, segregation and disintegration of the powder particles.
