Abstract Scope |
Lead and lead bismuth eutectic (LBE) are extremely corrosive at elevated temperatures (500-700°C) to conventional steels used in reactors. Flowing LBE introduces more challenges in terms of mechanical, thermal-hydraulics, and corrosion. To address these challenges, a high temperature corrosion test station was built at Niowave to test a variety of sample coupons in 500 °C flowing LBE for 1000 hours at high flow rates (>2 m/s). Several refractory materials and advanced alloys were tested and this presentation will address the evaluation of corrosion behavior of those samples. Initial results show promising corrosion resistance from refractory metals such as tantalum with significant degradation in the Fe-based alloys. |
