RMS-based b-value Analysis of Nuclear Piping Cracks under Realistic Noise Environments

Current Acoustic Leak Monitoring Systems (ALMS) in nuclear power plants (NPPs) are primarily designed for leak detection, often failing to identify precursor crack growth due to the masking effects of high-level mechanical background noise. This study proposes a robust RMS-based b-value analysis to evaluate crack progr...
