摘　　要：在10MW高温气冷堆(HTR-10)中,由于石墨构件的磨损会产生石墨粉尘,将影响反应堆的正常运行。石墨粉尘的产生主要来自堆芯、卸料管和装料管3个部位。本文在石墨磨损试验的基础上,保守地估算了HTR-10在正常运行工况下石墨粉尘的产生量(大约为2.74kg/年)。通过质量加权平均,给出了石墨粉尘的体积、面积和直径分布函数。In 10 MW High Temperature Gas-cooled Reactor (HTR-10), the wear of graphite components generates the graphite dust to influence the normal working of the reactor. The graphite dusts come from three parts: core, unload pipe and load pipe. Based on the graphite wear experiments, we here estimated that the graphite generation under normal working condition is about 2.74 kg/a. By the mass-weighted average, the distribution function of volume, area and diameter for graphite particle were obtained.
