Materials Reliability Program: Primary Water Stress Corrosion Cracking in Alloys 600 and 690: Quantitative Assessment of Crack Initiation Time (MRP-406)
Alloy 690 has replaced Alloy 600 in the construction of new nuclear power plants because of its superior resistance to stress corrosion cracking in primary water systems. This study compared crack initiation time for Alloy 690 and Alloy 600 to document Alloy 690’s ability to enable longer intervals between in-service inspections and to assess components’ […]
