高温气冷堆蒸汽发生器中石墨粉尘重悬浮规律研究
Study of Graphite Dust Resuspension in Steam Generator of HTR
摘要
Abstract
Graphite dust has an important effect on the safety analysis of high-tempera-ture gas-cooled reactor (HTR) .The flow field in steam generator was studied using computational fluid dynamics (CFD) method ,and the resuspension of graphite dust in steam generator was analysed .The results show that the resuspension fraction is nearly zero for the particles with the diameter of 0.1μm ,while it increases as the helium veloc-ity in steam generator increases for the particles with the diameter larger than 1 μm . The results also indicate that the resuspension fraction would increase as the diameter of the graphite dust increases at a given helium velocity .关键词
