Understanding Stress Corrosion Cracking (SCC), Affecting Variables and Prevention Strategies in Nuclear Power Plants—A Review

This review paper provides a comprehensive insight about the issue of SCC in NPPs, encompassing its economic impacts, mechanisms, material considerations, testing strategies, predictive modeling, and prevention methods. The study will explore the relationship between materials and environmental variables which cause the onset and progression of SCC in different materials commonly used for piping systems and related infrastructure. SCC stands as a noteworthy concern within the nuclear power industry, resulting in expensive downtime and repair procedures, and carrying potential severe safety implications. This comprehensive review will provide insights into the mechanisms underlying SCC and development of strategies for preventing and mitigating its effects on piping systems. By understanding the factors that contribute to SCC and how it can be mitigated, industries can develop strategies to prevent SCC related failures and ensure safe and reliable operation.
