    摘要： This invention provides a dripping nozzle device to produce ADU particles with good sphericity, a device for recovering a feedstock liquid to prepare a uniform feedstock liquid, a device for supplying a feedstock liquid to form drops with a uniform volume, a device for solidifying the surfaces of drops so that the drops will not deform easily when they fall onto and hit the surface of an aqueous ammonia solution, a device for circulating an aqueous ammonia solution so that the uranyl nitrate in the drops can be changed to ammonium diuranate completely, to such an extent that uranyl nitrate in the center of each drop is changed to ammonium diuranate, and an apparatus for producing ammonium diuranate particles with good sphericity. The dripping nozzle device is provided with a single vibrator to vibrate nozzles simultaneously. The device for recovering a feedstock liquid recovers the feedstock liquid remaining in the nozzles and mixes it with a fresh feedstock liquid. The device for supplying a feedstock liquid is provided with a light irradiator for irradiating falling drops with light. The device for solidifying the surfaces of drops sprays ammonia gas over each of the paths along which the drops dripping from the nozzles fall. The device for circulating an aqueous ammonia solution enables drops to flow upward in the aqueous ammonia solution in the aqueous ammonia solution reservoir. The apparatus for producing ammonium diuranate utilizes these devices.

    摘要： There is provided a process for the production of fuel compacts consisting of an isotropic, radiation resistant graphite matrix of good heat conductivity having embedded therein coated fuel and/or fertile particles for insertion into high temperature fuel elements by providing the coated fuel and/or fertile particles with an overcoat of molding mixture consisting of graphite powder and a thermoplastic resin binder. The particles after the overcoating are provided with hardener and lubricant only on the surface and subsequently are compressed in a die heated to a constant temperature of about 150.degree.C., hardened and discharged therefrom as finished compacts.

    摘要： 1. In a process for producing a tenacious zirconium carbide coating on graphite impregnated with uranium comprising the steps of impregnating a piece of porous graphite with uranyl nitrate dihydrate dissolved in tertiary butyl alcohol, enveloping said graphite piece in clean tertiary butyl alcohol solvent to dissolve said uranyl nitrate dihydrate impregnant from the surface of said graphite into a liquid, enveloping said graphite piece in liquid nitrogen to freeze said impregnated solution, evaporating said frozen solvent therefrom, whereby said uranyl nitrate dihydrate is deposited within said graphite pores, converting said uranium to the carbide by the application of heat, outgassing said graphite, applying a coating of finely divided zirconium suspended in liquid containing a carbonaceous binder onto said graphite surface, evaporating said liquid and converting said zirconium to the carbide by the application of heat whereby a zirconium carbide coating is obtained.
