Abstract

A pyrolytic carbon coated nuclear fuel particle and method of making it. The fuel particle has a core composed of a refractory compound of an actinide metal. The pyrolytic carbon coating surrounds the core so as to provide a void volume therebetween. The coating has an initial density of no greater than 1.45 grams/cm.sup.3 and an anisotropy factor than 3.0 and a final density upon heat treatment above about 2000.degree. C. of greater than 1.7 grams/cm.sup.3 and an anisotropy factor greater than 5.

Process to minimize cracking of pyrolytic carbon coatings

Patent Lackey, Jr., Walter J. (Oak Ridge, TN); Sease, John D [Knoxville, TN]

Carbon-coated microspheroids useful as fuels in nuclear reactors are produced with a low percentage of cracked coatings and are imparted increased strength and mechanical stability characteristics by annealing immediately after the carbon coating processes.

Pretreatment process for forming a smooth surface diamond film on a carbon-coated substrate

Patent Feng, Zhu [Albany, CA]; Brewer, Marilee [Goleta, CA]; Brown, Ian [Berkeley, CA]; ...

A process is disclosed for the pretreatment of a carbon-coated substrate to provide a uniform high density of nucleation sites thereon for the subsequent deposition of a continuous diamond film without the application of a bias voltage to the substrate. The process comprises exposing the carbon-coated substrate, in a microwave plasma enhanced chemical vapor deposition system, to a mixture of hydrogen-methane gases, having a methane gas concentration of at least about 4% (as measured by partial pressure), while maintaining the substrate at a pressure of about 10 to about 30 Torr during the pretreatment.

Pyrolytic carbon-coated nuclear fuel

Patent Lindemer, Terrence B [Oak Ridge, TN]; Long, Jr., Ernest L. (Oak Ridge, TN); Beatty, Ronald L [Wurlingen, CH]

An improved nuclear fuel kernel having at least one pyrolytic carbon coating and a silicon carbon layer is provided in which extensive interaction of fission product lanthanides with the silicon carbon layer is avoided by providing sufficient UO.sub.2 to maintain the lanthanides as oxides during in-reactor use of said fuel.

Method for applying pyrolytic carbon coatings to small particles

Patent Beatty, Ronald L [Oak Ridge, TN]; Kiplinger, Dale V [Concord, TN]; Chilcoat, Bill R [Knoxville, TN]

A method for coating small diameter, low density particles with pyrolytic carbon is provided by fluidizing a bed of particles wherein at least 50 per cent of the particles have a density and diameter of at least two times the remainder of the particles and thereafter recovering the small diameter and coated particles.

Methods for forming pitting resistant carbon coating

Patent Erylimaz, Osman L.; Singh, Harpal; Greco, Aaron C.; ...

A method for making a pitting resistant carbon coating that includes a hydrogenated diamond-like coating (“H-DLC”). The H-DLC is relatively soft and elastic. Unlike hard and/or inelastic coatings in the prior art, the present coatings do not exhibit a loss of adhesion (delamination). A bonding layer may be deposited on a metallic substrate and the deposited H-DLC on the bonding layer.
