Abstract

Kemals of nuclear fuel material are coated with pyrolytic carbon, cooled, exposed to air and coated again. Kemals of zirconium, uranium 235 and carbon made by sintering a mixture of zirconium carbide and uranium mionocarbide with a furfuryl alcohol binder are placed in a furnace comprising an electrically heated graphite tube, fluidized in a stream of argon whilst the temperature is raised to 1600 DEG C. and coated with pyrolytic carbon by adding methane to the argon. During the coating process the methane partial pressure is varied several times to produce discontinuities in the coating structure. The coated kemals are cooled, exposed to air for 10 hours and then coated with either a second pyrolytic carbon layer by heating to 1450 DEG C. in methane and argon or with a silicon carbide layer applied by cracking methyltrichlorosilane with hydrogen at 1500 DEG C.ALSO:A silicon carbide layer is applied to a pyrolytic carbon coating on a substrate containing zirconium, uranium 235 and carbon by cracking methyltrichlorosilane with hydrogen at 1500 DEG C.
