Proposed Crack Growth Rate Disposition Curves For Stress Corrosion Cracking Of Alloy 82 In BWR Environments

Product Number: ED22-18349-SG

Author: Peter L. Andresen, Robert G. Carter, Katsuhiko Kumagai

Publication Date: 2022

SCC in Fe- and Ni-base alloys has been observed in high temperature water, both in the laboratory tests and in BWRs. SCC results from complex interactions of ~10 primary variables and hundreds of secondary variables, broadly categorized in terms of stress, environment and microstructure.

There is extensive evidence from laboratory data and plant experience of the SCC susceptibility of Alloy 82 weld metal in both BWR and PWR environments. Two international expert panels evaluated laboratory data under PWR conditions and created disposition curves to address the effects of stress intensity factor (K), temperature, and other factors. Another expert panel is creating a disposition
curve under BWR conditions for K, temperature, corrosion potential, impurities, and other factors. Nickel alloy weld metals at lower Cr levels (~15% Cr for Alloy 182 and ~20% Cr for Alloy 82) are more susceptible to SCC than weld metals of higher Cr content (~30% Cr for Alloy 52/152). This paper focuses on on-thefly effects on SCC growth rate of Alloy 82 weld metal in BWR environments of corrosion potential, water
purity and temperature.
