基于流化床化学气相沉积的碳化硅材料制备、性能及其在核领域的应用
Preparation, Performance and Nuclear Applications of Silicon Carbide Materials Prepared by FB-CVD Method
摘要
Abstract
Results regarding the fabrication of SiC coating layers and other SiC-related materials for nuclear reactor applications are reported herein. A fluidized bed chemical vapor deposition (FB-CVD) method was used to prepare the SiC coatings, and the coating process was simulated using the newly proposed multiscale coupling model to enhance the coating uniformity. Different kinds of SiC series products, such as dense SiC layers, fine-grained SiC coating layers, SiC/C/Si mixed coating layers, porous SiC coating layers, SiC nanowires and SiC nanoparticles, were developed for nuclear energy applications. Postulated accident conditions, such as air ingress, wereconsideredto evaluate the reliability of the SiC coating layer. An irradiation test was also performed in ahigh-flux nuclear reactor, and the results validated the high performance of SiC coating materials in nuclear reactor applications.关键词
