摘要：

Molten salt is used as primary coolant flowing through graphite moderator channel of a molten salt reactor.Working at high temperature under radiation environment,the pore network structure of nuclear graphite should be well understood.In this paper,X-ray tomography is employed to study the 3D pore structure characteristics of nuclear grades graphite of IG-110,NBG-18 and NG-CT-10,and permeability simulation through geometries are performed.The porosity,number of pores and throats,coordination number and pore surface are obtained.NGCT-10 is of similar microstructure to IG-110,but differs significantly from NBG-18.The absolute permeabilities of IG-110,NG-CT-10 and NBG-18 are 0.064,0.090 and0.106 mD,respectively.This study provides basis for future research on graphite infiltration experiment.
