Suffered SCC (stress corrosion cracking) at the primary cooling system in 1980, the “Fugen” power station introduced the three preventive technologies immediately. After the upgrade of the plant, no SCC occurred during the operation period. We have inspected the actual structural materials of the “Fugen” power statio n on its decommissioning stage to evaluate effectiveness of SCC management technologies, which are combin ing material replacement, induction heating stress improvement (IHSI) to reduce the w...
