Compatibility Analysis of Lead Bismuth Coolant and Structural Materials
Lead bismuth eutectic alloy(LBE)is the preferred material for the coolant and spallation target of lead-cooled fast reactor,accelerator driven sub-critical system(ADS)coolant and spallation target,due to its low melting point,high boiling point,high thermal conductivity,good radiation resistance and stable chemical activity.However,liquid lead-bismuth alloy coolant will cause serious corrosion to common structural materials,so the study of material compatibility is very necessary and meaningful.This report investigates relevant parties to understand the corrosion mechanism of structural materials in liquid lead-bismuth alloy,get familiar with the specific process of corrosion test experiment,preliminarily screen out some materials to be tested,and analyze and study the compatibility of structural materials in liquid lead-bismuth alloy.
