Acoustic emission for real-time monitoring of stress corrosion cracking of 316LN stainless steel in simulated PWR primary water

Key Points

• Stress corrosion cracking was detected and monitored in real time, indicating potential risks for stainless steel structures.
• Acoustic emission techniques measured activity levels, with notable findings correlating to stress corrosion conditions over time.
• Observational analysis in simulated pressurized water reactor environments shows critical safety implications for materials.
• This highlights the need for ongoing monitoring practices in power generation to maintain structural integrity and safety.
