摘要： Fissionable-fuel or fertile elements for the core of a nuclear reactor, especially a reactor of the gas-cooled type, wherein the fuel or fertile material is introduced into graphite shells in the form of coated particles and a pyrolytically decomposable carbon-containing or silane gas is passed upwardly through the shell while the mass therein is heated by displacing an induction-furnace core downwardly around the graphite shell thereby bonding the coated particles together with pyrolytic carbon, silicon carbide or zirconium carbide being formed in situ to yield a coherent mass with a porosity of, say, 10 to 25 percent. The gas is preferably a mixture of one or more inert gases (nitrogen, argon or helium) with one or more hydrocarbons or carbon-containing gases (e.g., methane, acetylene, benzene, or silanes).

摘要： A PROCESS FOR PRODUCING COATED NUCLEAR FUEL PARTICLES HAVING IMPROVED FISSIN PRODUCT RETENTIN BY APPLYING A LOW DENSITY PYROLYTIC CARBON LAYER, FOLLWED BY A DENSE SILICON OR ZIRCONIUM CARBIDE LAYER AND THEREAFTER A DENSE ISOTROPIC PYROLYTIC CARBON LAYER. A THIN SEAL LAYER OF AN IMPERMABLE PYROLTIC CARBON IS DEPOSITED BETWEEN THE LOW DENSITY CARBON AND THE METAL CARBIDE LAYER. FOR CERTAIN CASES, AND PARTICULARLY WHERE OXIDE FUEL PARTICLES ARE EMPLOYED, AND ADDITIONAL SEAL LAYER OF AN IMPERMEABLE PYROLYTIC CARBON IS DEPOSITED IMMEDIATELY ADJACENT THE NUCLEAR FUEL CORE. FURTHER, THE PARTICLES MAY INCLUDE A LAYER OF DENSE ISOTROPIC PYROLYTIC CARBON DEPOSITED INTERIOR OF THE METAL CARBIDE LAYER. THE EXTERIOR DENSE ISOTROPIC LAYER SHOULD HAVE A THERMAL COEFFICIENT OF EXPANSION WHICH APPROXIMATES THAT OF THE METAL CARBIDE WITHIN ABOUT 20 PERCENT SUCH THAT THE METAL CARBIDE IS MAINTAINED IN COMPRESSION UNDER SUBSEQUENT IRRADIATION.
