Abstract
The problem of the effect of thermal loads on buckling strength is importan t in buckling research for fast breeder reactors, because an axial temperat ure gradient is produced in the main vessel and significant thermal stress is induced at the surface of sodium. In this paper, we focus on two types o f reactor vessels (loop type and pool type) and investigate the effect of t hermal loads accompanied by axial temperature changes near the sodium surfa ce. In addition, the reduction of the buckling strength due to thermal load s is evaluated.
