Steam Generator Management Program: Summary of 2016 Research into Lead Stress Corrosion Cracking Trends—Effect of Applied Potential on Alloy 690TT and pH on Alloy 800
Recent research suggests that the presence of lead can be linked to stress corrosion cracking of steam generator tubing in nuclear plants. In this study, EPRI investigated the conditions of a plant’s secondary water in which tubing materials are susceptible to lead-related stress corrosion cracking.
Traditional heat treatments used in production of parts made of alloy 718 may not be optimal for the corrosive, irradiated environment of pressurized water reactors, potentially leading to fuel assembly component degradation. This study evaluated 11 different thermo-mechanical treatments for alloy 718 for their ability to reduce susceptibility to stress corrosion cracking and irradiation-assisted stress […]
