Název v původním jazyce

Corrosion Resistance of Alumina-Forming Austenitic Steels Under Simulated Accident Conditions for SCWR and SCW-SMR Applications

Popis výsledku v původním jazyce

This study evaluates the potential of Alumina-Forming Austenitic (AFA) steels, containing 2–5% aluminium, derived from SS 310S, material for Small Modular Reactors cooled by Supercritical Water (SCW-SMR). AFA steels exhibit high-temperature corrosion resistance due to alumina (Al2O3) scale formation and enhanced mechanical strength via precipitation hardening. As part of the international ECC SMART project which aims to develop SCW-SMR, flat coupons were exposed to water at 380 °C and 25 MPa for 1000 hours, where water properties change drastically. The exposed samples were analysed using SEM-EDS/EBSD to evaluate the bulk material microstructure and to determine the corrosion layer. Based on weight gain and thin oxide layer formed on the surface, a very low corrosion rate was detected.
