英文摘要	Mesocarbon microbeads and the isostatic pressing method were used to prepare binderless nanopore-isotropic graphite (NPIG) as a neutron moderator and reflector, to inhibit liquid fluoride salt and Xe-135 penetration during use in a molten salt nuclear reactor. The microstructure, thermophysical, and other properties of the NPIG were studied and compared with isostatic graphite (IG-110, TOY TANSO CO., Ltd., Japan). A high-pressure reactor and a vacuum device were constructed to evaluate the molten salt and Xe-135 penetration in the graphite, respectively. The results indicated that NPIG possessed a graphitization degree of 74% and excellent properties such as a high bending strength of 94.1 +/- 2.5 MPa, a high compressive strength of 230 +/- 3 MPa, a low porosity of 8.7%, and an average pore diameter of 69 nm. The fluoride salt occupation of IG-110 was 13.5 wt% under 1.5 atm, whereas the salt gain in NPIG remained steady even up to 10 atm with an increase of <0.06 wt%, demonstrating that the graphite could inhibit the liquid fluoride salt infiltration effectively. The helium diffusion coefficient for NPIG was 8.76 x 10(-5) cm(2)/s, much less than 1.21 x 10(-2) cm(2)/s for IG-110. The NPIG could effectively inhibit liquid fluoride salt and Xe-135 penetration.
