Boiling Water Reactor Core Shroud Stress Corrosion Cracking surface machining
To verify the effect of hardened surface on stress corrosion cracking (SCC) of 316L, characteristics of cracked BWR core shroud have been investigated by means of microstructures. At the inner surface of core shroud where grinding was done, fine grains were observed at the surface thin layer. Furthermore, deformation-induced slip-line field including extensive deformation-twins was observed in the harden ed surface region. In contact with corrosion products on the shroud surface, intensive Ni enrichment a...
