Patent · Sat Jan 01 00:00:00 EST 1983

OSTI ID:864538

Blocher, Jr., John M.; Veigel, Neil D.; Landrigan, Richard B.

A method of coating ceramic nuclear fuel particles containing a major amount of an actinide ceramic in which the particles are placed in a fluidized bed maintained at ca. 800.degree. to ca. 900.degree. C., and niobium pentachloride vapor and carbon tetrachloride vapor are led into the bed, whereby niobium metal is deposited on the particles and carbon is deposited interstitially within the niobium. Coating apparatus used in the method is also disclosed.
