Abstract
Approximately 4000 sintered, 25 wt% Pu02-75 wt% U02, FFTF type fuel pellets were fabricated in the initial test of the FFTF Fuel Pin Fabrication Development and Demonstration Facility.The materials, equipment, techniques, and sampling used in the fabrication are described.Complete characterization of the sintered pellets including dimensions, density, chemical composition, and homogeneity is reported.The sintered pellets have an average density of 91.35% TD and an average oxygen-to-metal ratio of 1.99.The pellets are homogeneous, and no evidence of the existence of more than one phase was detected.The O/M of 200 of the sintered pellets was reduced to 1.96.One hundred of the pellets were centerless ground for use in determining pellet density by geometrical methods.
