Savannah River Laboratory monthly report: {sup 238}Pu fuel form processes

Description: Progress during August 1975 in the development of {sup 238}PuO{sub 2} heat sources is reported. In studies to characterize {sup 238}PuO{sub 2}, the following were concluded: particle size was determined to be the most important characteristic affecting the variation in fabricability of {sup 238}PuO{sub 2}; problem feed consists of smaller particles (2 to 4 {mu}m) than older, acceptable feed (4 to 6 {mu}m). The particle size of new feed has varied from 3 to 10 {mu}m primarily as a result of vary… more

Savannah River Laboratory monthly report: {sup 238}Pu fuel form processes

Description: In direct-strike {sup 238}PuO{sub 2}, agglomeration occurs in the oxalate precipitate and is unaffected by washing agent or calcining temperature. The evaluation of an automatic pulverizer-classifier for the PuFF Facility was begun. Difference between the mini-hot press at SRL and the LASL full-scale hot press require higher pressures to be used at SRL to obtain the density specified for PPO. Hot-pressed density was found to vary with applied pressure and, to a lesser extent, with size of feed.… more
