Lead-bismuth eutectic(LBE)was one of primary candidate materials for coolant in advanced nuclear reactors,such as accelerator driven system(ADS)and fast neutron reactor,due to its low melting point,low reactivity,low vapor pressure,low viscosity and fast heat removal,etc[1;2].However,it is known that severe corrosion occurs in the presence of liquid Lead-bismuth eutectic alloy,especially at high temperature.Therefore,the selection of the structural material exposed to LBE is an extremely complex problem and compatibility tests are required.
