| 中文摘要 | 10 MW高温气冷实验堆中石墨粉尘的产生会对一回路冷却剂氦气的品质以及高温堆内仪器设备的可靠运行带来很大的挑战,因此在一回路氦净化系统入口处设置了高性能不锈钢烧结金属过滤元件来确保系统的安全运行。组合不同过滤精度的过滤元件可以对石墨粉尘的粒径分布等进行研究,提供10 MW高温堆不同运行状况下石墨粉尘的相关信息,对反应堆安全正常运行具有重要意义。本文针对过滤元件的过滤机理进行了研究,对过滤效率的理论模型进行了分析,利用聚焦粒子束扫描电子显微镜观察烧结金属过滤元件的表面微观结构特征,为高温堆中石墨粉尘的取样测量研究奠定了基础。; The graphite dust in the 10 MW high temperature gas-cooled reactor will bring great challenges to the quality of the primary loop coolant and the reliable operation of equipment of the HTR-10,so high-performance stainless steel sintered metallic filter elements are installed at the entrance of the helium purification system to ensure the safe operation of the system. The particle size distribution of the graphite dust can be studied by combining different filtration fineness filters. It can provide the information of the graphite dust under different operating conditions of the HTR-10,which is of great significance to the normal reactor operation. The filtration mechanism of the filters has been studied,the theoretical model of the filtration efficiency has been analyzed,and the surface microstructure characteristics of the sintered metallic filter elements has been observed with SEM( focused ion beam scanning electron microscope),which lay a good foundation for the further study on the sampling measurement of the graphite dust in the HTR-10. |
