包覆颗粒燃料涂层工艺是高温气冷堆(HTGR)关键技术之一。在研究制备工艺参数对包覆层性能的影响的基础上,确定了制备包覆颗粒燃料的最佳工艺条件,并制备出达到冷态设计要求的 Triso 型包覆颗粒燃料。
Coated particulate fuel coating process is one of the key technologies of high temperature gas cooled reactor (HTGR). Based on the study of the influence of the preparation parameters on the properties of the coating, the optimum process conditions for the preparation of the coated pellet fuel were determined and the Triso coated pellet fuel which reached the cold design requirement was prepared.
