Key Industry Lessons Learned from Tabletop Inspection Process Overarching theme: clarity and documentation are vital

  • Use and definition of various models Model of record Working models Application specific models
  • Process for incorporating new types of equipment/operational procedures (e.g. FLEX, OPC)
  • Documentation and procedures for engagement with engineering on modification reviews

Future Engagement with NRC Orderly and predictable roll-out Scope of training for NRC regional staff and other staff supporting inspections

  • Consistency in interpretations
  • Delineation between information and operating experience Appropriately sized inspection process
  • Inspection team size
  • Scope of inspection
  • Ensure no repetition of previous reviews Inspection interval
  • Four years conflicts with schedule for application-driven model updates
  • Consider lengthening to make best use of NRC and licensee resources
