Risk-informed Process for Exemptions Next Steps Tim Reed, NRR/DORL Antonios M. Zoulis, NRR/DRA

2 A Map of the Universe of Findings High safety Low safety Clearly within the licensing basis Address issue with appropriate tools such as:

  • Enforcement
  • Order
  • Inspect licensee corrective actions Clearly within the licensing basis Address finding/violation with appropriate tools (i.e.,

either the licensee comes into compliance or proposes changes to the licensing basis):

  • Inspect licensee corrective actions (e.g., 50.59, PI&R)
  • Change the licensing basis (LAR, relief, exemption, etc.)
  • Assess adequacy of the requirement (i.e., rulemaking)

Not clearly within the licensing basis Evaluate issue to determine regulatory actions with tools suchas:

  • 50.54(f) or generic communication
  • Backfitting
  • Generic issue process
  • Use LIC-504 and TIA as applicable Not clearly within the licensing basis but clearly low safety significance EXIT:
  • Document decision
  • Make public record Address issues in this quadrant

3 Open to Graded Approach 50.69 & TSTF 505 TSTF-425 and TSTF-505 TSTF-425 Other risk information Streamline Review - No review of PRA or deterministic review Type 2 Deterministic Review Risk-informed review

4 Whats Next?

  • Further develop example safety impact evaluations.
  • Enhance NRR staff guidance.
  • Finalize RIPE guidance.
  • Focus on top tier but continue evaluating graded approach to review based on use of different risk-informed initiatives and other risk information.
  • Continue interactions with public and other interested parties.
