Alloy 600 activities


Key components of the primary system Reactor Pressure Vessel made of Alloy 600 and welded with Alloy 82/182 are highly susceptible to Primary Water Stress Corrosion Cracking (PWSCC). Framatome offers Ultra High Pressure (UHP) Cavitation Peening to protect the Reactor Pressure Vessel Head, Primary Circuit and Bottom-Mounted Nozzles against surface-induced PWSCC. It enables cost efficiency and lower outage impact compared to traditional repair methods without risk of damaging the primary circuit components. Frequency of Non-Destructive Examination inspections can be also reduced.
