Where do savings come from? Where do savings come from? Reduce capital costs Examples: Vogtle MSIV Actuators, Hatch Plant Service Water Piping Projects Remove components from special treatment programs and extend or eliminate PMs Example: Equipment Qualification Program, In- Service Testing Right Work at the Right Time! Programs Procurement - Daily and Outage Reduce parts cost by 80% Solve obsolesce issues Cut lead time in half or more 4

Implementation Tips and Lessons Learned Implementation Tips and Lessons Learned Think 50.69 early and often, especially in Design space. Salvaging Opportunities vs. Maximizing Benefits Include all affected departments in change management for 50.69 Team Sport Align PRA model updates with 50.69 Periodic Review Make it easy!! Use what is in place Do not add more process than what is needed Ensure easy reinstatement of special treatments if needed 11
