摘要	Fatigue strength of the structural materials of lead -cooled fast reactors (LFRs) and accelerator -driven systems (ADS) may be degraded in liquid metal (Lead or lead -bismuth eutectic (LBE)) environments. The fatigue crack growth (FCG) data of structural materials in liquid LBE are necessary for damage tolerance design, safety assessment and life management of key equipment. A novel monitoring system for fatigue crack length was designed on the compliance method and the monitor technology of crack opening displacement (COD) of CT specimens by the linear variable differential transformers (LVDT) system. It can be used to predict the crack length by monitoring the COD of CT specimens in harsh high -temperature liquid LBE using a LVDT system. The prediction accuracy of this system was verified by FCG experiments in room temperature air and liquid LBE at 150, 250 and 350 degrees C. The first results obtained in the FCG test for T91 steel in liquid LBE at 350 degrees C are presented.
