WebIn boiling water reactors (BWRs), stress corrosion cracking (SCC) has occurred in Alloy 600 and Alloy 182, 132 and 82 weld metals. Most BWRs mitigated SCC by injecting H 2 into the feed water, although the levels vary by ~8X depending on whether they use electrocatalysis and low H2, or only moderate H 2.Under moderate hydrogen water chemistry conditions, … WebMDM Results for BWR: – Fatigue & Fracture Toughness Fatigue Ei tlEff t Fti LifEnvironmental Effects on Fatigue Life Hi hHigh-CTh lF ti fBWRPi iC Thermal Fatigue of BWR Piping 2008 2010 LTO 2008 2010 LTO Lo-C Env.
