摘　　要：分析了10MW高温气冷堆(HTR-10)中的石墨粉尘在热气导管中的沉积情况,得到了石墨粉尘在热气导管中的沉积率。在分析计算中,考虑了石墨粉尘在热气导管中的紊流沉积和热泳沉积。计算结果发现,石墨粉尘在热气导管中的沉积量非常小,其主要原因是氦气的流速较高。The deposition of graphite dust in heat gas duct of 10MW high temperature gas-cooled reactor （HTR-10） was analyzed. The deposition efficiency of graphite dust in heat gas duct was obtained, which was necessary to estimate the radioactivity activity at the surface of heat gas duct. in the analysis, the turbulent deposition and thermophoretic deposition of graphite dust were involved. The calculation results revealed that the deposition amount of graphite dust in heat gas duct was small due to the large flow velocity of helium in heat gas duct.
