Description

Progress in the development of manufacturing procedures and techniques for uranium dioxide fuel pellets is described. Specifications for both the uranium oxide powder and the final fuel pellet are given. A process is described for making pellets wlth closely controlled density, dimensions, purity, and freedom from structural defects from ADU (ammonium diurante process) uranium dioxide powder. A formula relating lineaashrinkage to green and fired densitles has been derived, This formula has proven a useful tool in control of fired or slnterod pellet dimensions and densities esses described were utillzod in the manufacture of pellets for use in critical experiments. Improvements ... continued below
