FUEL FOR HIGH-TEMPERATURE NUCLEAR REACTORS

Patent ·
OSTI ID:4045988

Metal cans or cladding for reactor fuel elements cannot be used when the operating temperature is high; in order to limit the diffusion of fission products, small amounts of zircomum, niobium, silicon or magnesium are incorporated to the ceramic type fuel. These metals, their oxides and carbides reduce the vapor pressure of the fission products. The uranium (or uranium dioxide) is mixed with reactor-grade carbon and preferably zirconium carbide, the mixture is compacted, degassed, and sintered under vacuum at 2000 deg C. (EURATOM)
