Abstract:Development of the Gel-Addition Process for mixed urania-plutonia fuels has continued. UO^ sols have been prepared by the ORNL Formate Process. Gel spheres were made by drying sol droplets in a recirculating column containing a 2-ethyl hexanol bath. Carbon analyses at various steps show that at least half the carbon added (as urea and formate during sol preparation) remains in the sol. Gelation roughly triples the carbon level (C/U atoms ratio in gel = 1. 5). A study of the gelation bath composition showed tha… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
