摘要：

Wastage phenomena on adjacent tubes (target-wastage) arise from water/steam leak in steam generators of sodium-cooled fast reactors. Target-wastage is likely to be caused by liquid droplet impingement erosion and flow-accelerated corrosion in an environment marked by high-temperature and high-alkali (reaction jet) due to sodium-water reaction. The static and flow-accelerated corrosion experiments have been carried out as a part of phenomena elucidation experiments for target-wastage by using actual tube material under high-temperature sodium-hydroxide and sodium monoxide conditions which are mainly generated by sodium-water reaction. The authors evaluated the dependence of liquid/tube material temperature and liquid velocity upon the flow-accelerated corrosion rate on the tube and derived the new correlation of flow-accelerated corrosion for target-wastage taking into account local wastage environment in this report. ©2013 The Japan Society of Mechanical Engineers.
