ABSTRACT:
There is provided a process for the production of spherical fuel and/or fertile oxide or carbide particles for a nuclear reactor, especially a high temperature reactor, by casting an aqueous solution of a uranium and/or a thorium and/or plutonium salt, as well as in the case of the production of carbide particles finely dispersed carbon also, from a vibrating nozzle, passing the drops formed through an ammonia containing gas zone into an ammoniacal precipitation bath with subsequent washing, drying and sintering or melting. To the aqueous solution there is added individually or in admixture a water soluble or water miscible monomeric hydrocarbon having an aldehyde, keto, ether, amino, imino, phenol, carboxylic acid or carboxylic acid amide group, which substituted hydrocarbons form stable adducts with uranium, thorium and plutonium in aqueous alkaline solution, which adducts cannot be washed out with water and which does not impart to the solution a viscosity of over 15 cp at 20.degree. C.
