Microstructural Observation of SiC/C Coated Layer on a Nuclear Fuel

다국어 초록 (Multilingual Abstract)

Microstructural observation of SiC/C coated layer on a nuclear fuel was carried out to develop a coated nuclear fuel technology. Silicon carbide layer was formed by a combustion reaction between silicon and pyrolytic carbon layers, which were prepared by a fluidized bed type chemical vapor deposition unit and ECR PECVD equipment, respectively. Deposition rate significantly depended on the initial source gas content, flow rate and coating temperature. Morphology of the pyrolytic carbon had equiaxed grain, which layers depended on the initial substrate shape. Chemical analysis of the layer by EDX and AES and microstructural observation with SEM and TEM revealed that inner and outer layers were pyrolytic carbon with equiaxed grains □ respectively.
