Materials Reliability Program: Stress Corrosion Crack Initiation Testing of Nickel-Base Alloys for Pressurized Water Reactor Applications—Part 1 (MRP-426)
In reactor pressure vessel boundary components made of nickel alloys, stress corrosion crack growth has been a key factor in setting inspection intervals and considering life extension of nuclear plants. EPRI now seeks to use stress corrosion crack initiation in the same way. Researchers conducted lab tests on stress corrosion crack initiation in Alloys 600/182 […]

Materials Reliability Program: Specification Guideline for Primary Water Stress Corrosion Cracking Mitigation by Surface Stress Improvement
Stress corrosion cracking is a type of degradation that can affect components in nuclear plants. Peening (also known as surface stress improvement) is a technology that can help mitigate this degradation by modifying the stress on metal surfaces. These guidelines are intended to help U.S. nuclear utilities prepare technical specifications for peening in three areas: […]
