Liquid lead-bismuth eutectic (LBE) is considered as a coolant of fast reactors, a target material of accelerator drive systems and a coolant of concentrated solar power systems. The liquid LBE systems operated at 1173 K can be applied as a heat source to hydrogen production. Although 316L austenitic steel is a candidate structural material, the corrosion data of 316L steel in flowing LBE at 1173 K is still limited. The liquid metal stirring pot was modified to perform the corrosion test at 1173 K. The corrosion test of 316L steel in stirred LBE was performed at 1173 K for 250 hours. The occurrence of corrosion-erosion was not recognized on the specimen. The specimen showed a mass loss of 5.28 g/m².
