Q&A / Discussion
More-than-Minor Screening Criteria Alex Garmoe Senior Reactor Analyst Reactor Assessment Branch Division of Reactor Oversight Office of Nuclear Reactor Regulation
More-than-Minor Screening Criteria
- ADVANCE ACT Section 507 prompted review of issue screening process
- ensure NRCs regulatory oversight is risk-informed and performance-based
- Prior issue screening updates implemented earlier this year
- Expanded applicability of VLSSIR
- Elimination of dual-path TE-ROP screening option for Green issues
- More-Than-Minor decision-making consistency and efficiency has long been a focus area
- Questions/criteria involve subjectivity
- Roughly 100 examples in IMC 0612 Appendix E
More-than-Minor Screening: Current State
- IMC 0612 Appendix B questions:
- reasonably be viewed as a precursor to a significant event?
- have the potential to lead to a more significant safety concern?
- associated with one of the cornerstone attributes and adversely affect the associated cornerstone objective?
- Use IMC 0612, Appendix E, or the Security Issues Forum process to inform answers to the screening questions listed above.
- Additional background guidance in IMC 0612 Section 5
- requires inspectors to apply reasonable judgment
- some variability will exist whenever different inspectors have to apply judgment to unique and site-specific circumstances
More-than-Minor Screening: Future State
- Next step in ADVANCE Act Section 507-driven changes to issue screening is improving the MTM determination
- Address the subjectivity and judgment in current criteria
- Reduce the level of effort required to make the determination
- Enhance consistent and predictable outcomes
- These can be achieved by relocating MTM to IMC 0609 documents
- Already a familiar tool that is part of issue screening process
- More objective than the existing MTM questions/criteria
- IMC 0612 Appendix E examples would be eliminated
- Review and revision of IMC 0612 and 0609 documents is underway along with Baseline Inspection Program revisions

Future State:
More-than-Minor Screening Criteria From IMC 0612 to IMC 0609
Impacts of the Proposed Change
- Replacement of broad criteria with targeted, cornerstone-specific criteria
- Reduction in the degree of subjectivity and judgment involved
- Opportunity to revisit the threshold of more-than-Minor
- Restricted to Minor/Green decision-making, did not consider greater-than-Green threshold under this effort
- Synced with changes to greater-than-Green criteria in Security and EP that are unrelated to this effort
- Does not impact overall issue screening process (0612B flowchart)
Impacts of the Proposed Change
- Document revisions and internal comment are ongoing and specific wording and criteria are not yet finalized
- Example impacts based on current status:
- Currently everything entering 0609 appendices is at least Green
- Proposed Appendix A revisions include 10 questions in which Green becomes Minor
- Proposed Appendix F revisions include 14 questions in which Green becomes Minor, issues with low degradation rating are now Minor
- It is anticipated that many of the Green findings associated exclusively with degradations in margin or minor calculational errors, in which operability/functionality/qualifications were maintained, would screen to Minor
Impacts of the Proposed Change
- No MTM example in IMC 0612 Appendix E covering RCS leakage
- RCS Leakage is an attribute of the Barrier Integrity Cornerstone
- At what point does RCS leakage result in a YES to the existing IMC 0612 Appendix B questions?
Impacts of the Proposed Change
- Current MTM examples in IMC 0612 Appendix E dont define transient
Impacts of the Proposed Change Revised IMC 0609A Question 1 for Mitigating Systems removes concept of reasonable doubt Existing IMC 0612E example:
Impacts of the Proposed Change
- It is expected that the number of Green findings will be reduced
- Intention is to maintain Green findings impacting
- Plant stability (trips and >10% transients)
- SSC operability, availability, qualification that would affect performance of intended function (without considering comp measures, mods/repair, etc.)
- Unplanned dose exposures or rad material release
- EP: Impact to the 6 planning standards that can still be greater-than-Green
- Not an all-inclusive list
- Some future adjustments may be needed given scope and pace of this effort
- For the same reason, it is expected that some issues may be approved for deviation from the default screening approach
- Minor violations require correction - CR (number and title) may be included in Inspection Reports
Implementation of Changes
- Implementation is subject to Commission approval of the approach
- Request for approval will be contained in ROP Baseline Inspection Program Revision SECY
- Document revisions are ongoing with regional comment in October and November
- Revised document issuance throughout December
- Implementation, pending approval, in January 2026
Questions and Discussion on the Revision to the More-than-Minor Issue Screening Guidance
New Engineering Inspection Doug Bollock Senior Reactor Operations Engineer Reactor Inspection Branch Division of Reactor Oversight Office of Nuclear Reactor Regulation
Elements of New Engineering Inspection Procedure
- New Inspection Procedure (IP 71111.21A):
- Tailored to specific Structures, Systems, and Components (SSCs) being inspected.
- Inspection Team & Duration:
- 2-3-member team (includes resident inspector).
- Onsite for two weeks
- Inspection can be completed in two consecutive weeks or spread out over some time period within a year, depending on the samples selected.
- Inspection effort:
- 175-210 hours (defined in the inspection plan).
- Flexible Scope & Focus:
- Inspection scope is adaptable to target problem areas.
- Specific guidance based on SSCs selected for inspection.
- Resource Flexibility:
- Flexibility in inspection resources used to support the effort.
New Engineering Inspection Objectives
- To assess current engineering performance to maintain risk-significant systems, structures, and components (SSCs) capable of performing their design basis functions under bounding conditions described in the plant design and licensing bases.
- To assess current engineering performance to maintain SSCs defense-in-depth capability with safety margins provided for in the design and licensing bases.
- To provide insights regarding current engineering performance to maintain SSCs consistent with probabilistic risk assessments (PRAs) used for regulatory activities.
New Engineering Inspection Procedure Elements
- The IP is intended to be used to implement the technical requirements and guidance in past engineering inspection procedures (but not limited to):
- Sample types implemented under this IP will therefore cover several types of samples such as CGD packages, aging-related component reviews, fire protection SSCs and administrative controls, POV design basis evaluations, modifications, 10 CFR 50.59 screenings and evaluations, and operating experience reviews.

New Engineering Inspection Procedure Planning
- The inspection lead will develop an inspection plan that implements the referenced IP(s) objectives within the resource estimates. There will be an IP attachment that may be used as a reference to build the inspection plan.
- The inspection lead will gather information from the licensee describing current engineering activities. This activity should commence approximately 180 days and no later than 120 days prior to the scheduled onsite inspection (if inspection scope is known, specific request for information may be sent closer to the inspection date).
- This can be accomplished by document requests and/or discussions with the site Resident
- The Regional End of Cycle Meeting can also be used as input to the inspection.
- Inspection plans should demonstrate a focus on current licensee engineering performance (last 4 years ).
- During sample selection, the inspection lead should review prior inspection history and consider selecting a sample that has not been reviewed recently at the site.
Problem Identification and Resolution (PI&R)
Inspection Procedure Changes Sarah Obadina Reactor Operations Engineer Reactor Inspection Branch Division of Reactor Oversight Office of Nuclear Reactor Regulation
PI&R Inspection Procedures
- Baseline IP (IMC 2515 App A)

- Current sections of PI&R Team Inspection included as optional samples:
- Licensee audits and self-assessments
- Licensee use of operating experience
- Review of issues that pose challenges to the free flow of information for adequate resolution
- Reactive IP (IMC 2515 App C)
- Entry Criteria
- Regional Administrator approval
PI&R Team Inspection
- Two-member team, onsite for one week (Flexibility on inspection resources used)

PI&R Team Inspection Entry Criteria
- Entry Criteria for implementation of team inspection1, as approved by the Regional Administrator
- 1) Findings:
- Two or more Greater-than-Green (GTG) findings in the area of PI&R in any 12-month period, or
- Greater than 5 cumulative findings in the area of PI&R in any 12-month period that the regional office has concerns about the adequacy of the licensees corrective actions
- 2) Supplemental Inspections:
- Supplemental inspection identifies and documents a significant weakness in the PI&R program which the licensee did not identify, or
1)
The team inspection will be applicable to Columns 1, 2 & 3 of the Action Matrix. The team inspection is not recommended in Column 4 of the Action Matrix due to duplication in inspection effort for an IP 95003 Supplemental Inspection.
2)
There will be two IMC 2515 App C inspections for SCWE: IP 93100 and this new PI&R team inspection. Only one of these inspections should be conducted for a SCWE issue. The regional administrator should choose the inspection that is most applicable.
