Abstract
Three nuclear fuels, pure urania, 5% and 10% gadolinia containing fuel s were coated with boron nitride to improve nuclear and physical prope rties. Coating was done by plasma enhanced chemical vapor deposition t echnique by using boron trichloride and ammonia. The specimens were ex amined under a scanning electron microscope. Boron nitride formed a gr ainy structure on all fuels. Gadolinia decreased the grain size of bor on nitride. The fractal dimensions of fragmentation and of area-perime ter relation were determined.
