英文摘要	A fixed-bed deposition method was used to prepare rough laminar pyrolytic carbon coating (RLPyC) on graphite for inhibiting liquid fluoride salt and Xe-135 penetration during use in molten salt breeder reactor. The RLPyC coating possessed a graphitization degree of 44% and had good contact with graphite substrate. A high-pressure reactor was constructed to evaluate the molten salt infiltration in the isostatic graphite (IG-110, TOY TANSO CO., LTD.) and RLPyC coated graphite under 1.01, 1.52, 3.04, 5.07 and 10.13 x 10(5) Pa for 12 h. Mercury injection and molten-salt infiltration experiments indicated the porosity and the salt-infiltration amount of 18.4% and 13.5 wt% under 1.52 x 10(5) Pa of IC-110, which was much less than 1.2% and 0.06 wt% under 10.13 x 10(5) Pa of the RLPyC, respectively. A vacuum device was constructed to evaluate the Xe-135 penetration in the graphite. The helium diffusion coefficient of RLPyC coated graphite was 2.16 x 10(-12) m(2)/s, much less than 1.21 x 10(-6) m(2)/s of the graphite. Thermal cycle experiment indicated the coatings possessed excellent thermal stability. The coated graphite could effectively inhibit the liquid fluoride salt and Xe135 penetration.
