Choose the right perspective
Match the person's licensing work to your need, since operating plant amendments, license renewal and new reactor applications involve different NRC processes and timelines. Also consider whether you need a site-level licensing manager who knows one plant's licensing basis or a fleet-level leader who sets licensing strategy across several plants.
Questions to take into the conversation
- 01How do you decide when a plant change needs a license amendment request rather than an evaluation under the existing licensing basis?
- 02What do you do before submitting to the NRC to reduce requests for additional information and keep the review on schedule?
- 03How do you staff and sequence a license renewal or new reactor application alongside routine licensing work?
