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, exemptions, etc.)
  • Assess adequacy of the requirement (i.e., rulemaking)

Not clearlywithin 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 Risk-informed Process for Evaluations (RIPE)

  • RIPE establishes a more efficient process to review licensing actions that address low safety significance (LSS) issues.
  • RIPE leverages existing regulations and approved risk-informed initiatives to create a streamlined NRC review process for plant-specific exemption and license amendment requests for LSSissues.
  • Adoption of RIPE was recommended in a memo to the NRR Office Director dated January 5, 2021 (ML20261H428).

4 What is RIPE?

Regulations Does not generically apply to regulatory issues and is not intended to displace rulemaking.

Does address unique plant non-compliance issues that would be specific to a narrow portion of the regulation for that licensee.

Evaluation Does not change how licensees make the determination concerning validity of licensing request.

Does inform the level-of-effort NRC staff will expend to conduct review and approval/denial of license requests.

Inspection/Enforcement Does not involve inspection and enforcement of findings and violations.

Does support how those violations and findings are corrected.

5 How Does RIPE Work?

Leverages work done in previous risk-informed initiatives IDP TSTF-505 RIPE (using existing regulations)

Integrated Decision-making Panel (IDP) Reviews Key Engineering Principles Demonstrates Probabilistic Risk Assessment Acceptability

Licensee identifies non-compliance that has a minimal safety impact Licensee documents the exemption or amendment request using Guidelines for Analyzing the Safety Impact of Issues (ML20261H462)

Licensee requests licensing action per streamlined review process 6

NRC reviews licensing action using streamlined review guidance in TSG-DORL-2021-01 (ML20261H473)

Approval Process Safety Impact Characterization Submittal to NRC Implementation of RIPE NRC Actions Licensee Actions

7 Why RIPE?

  • Focus NRC and licensee resources on the most safety significant issues.
  • Address low safety compliance issues in an efficient and predictable manner consistent with NRC's Principles of Good Regulation.
  • Leverage existing regulations and risk insights.

8 Whats Next?

  • Explore expansion of RIPE to include:

- Exemption and amendment requests from licensees that do not have an approved TSTF-505 (Risk-Informed Completion Times) amendment, but have an approved TSTF-425 (Surveillance Frequency Control) amendment or can provide other forms of risk information.

- Exemption and amendment requests in other areas (EP, Security, etc)

  • Continue outreach to interested parties
