Special steel resists corrosion in liquid metal for nuclear reactors

AI Insight

This study investigates the corrosion behavior of T91 ferritic-martensitic steel when exposed to static lead-bismuth eutectic (LBE) under oxidizing conditions. The research examines how protective oxide layers form and evolve over time on the steel surface, which is critical for understanding material degradation in liquid metal environments. The findings reveal the mechanisms of oxide scale formation and provide insights into the long-term performance of T91 steel in LBE systems.

Why it matters

T91 steel is a candidate structural material for advanced nuclear reactors and accelerator-driven systems that use lead-bismuth eutectic as a coolant. Understanding its corrosion resistance is essential for ensuring the safety and longevity of next-generation nuclear energy systems operating at high temperatures.
