Abstract
1,249,336. Nuclear fuel. OSTERREICH. ISCHE STUDIENGESELLSCHAFT FUR ATOMENERGIE G.m.b.H. 2 Dec., 1968 [7 Dec., 1967], No. 57163/68. Heading G6C. [Also in Division C7] Coated uranium, plutonium, or thorium oxide nuclear fuel particles are produced by spraying a mixture of a solution of a compound of the metal and a polymerizable organic substance to form particles, carbonizing the organic substance and transforming the metal compound in the presence of a protective gas into the form of oxide dispersed in a carbon matrix, and forming a gas-tight coating on the resultant particles. An aqueous solution containing uranium nitrate, a phenol or amine, and an aldehyde may be sprayed into an oil bath to form small particles which are heated as a fluidized bed at 1200 C. in the presence of argon or CO. When argon is used, the particles are coated with carbon by decomposition of methane firstly at 1200- 1400 C. and then at 2200-2700 C. When CO is used as the protective gas, the lower temperature coating may be omitted. The particles can withstand temperatures up to 2800 C. or higher without migration of nuclear fuel into the coating. Reference is also made to the preparation of particles of high melting point oxides of rare earth and other elements. Coatings of silicon carbide, zirconium carbide and tantalum carbide may be applied instead of carbon coatings. Reference has been directed by the Comptroller to Specification 1,146,015.
