Reconciliation OMA Change Evaluation Scope Oconee FAQ 06-0012 Binning Examples 2
Purpose of OMA Reconciliation NFPA 805, Section 4.2.4, in reference to the use of OMAs for the performance based approach states additional risk presented by their use shall be evaluated.
Process can contribute to safety by eliminating unnecessary OMAs Presentation Focus: Determine which compliance strategy OMAs are allowed and those that require change evaluation 3
OMA Change Evaluation Scope OMAs that are either not allowed under the current regulatory framework or for which there is no previous NRC approval are not compliant with current regulations.
NEI 04-02 FAQ 06-0012 clarifies which operator manual actions that will require change evaluations during the transition to NFPA 805.

FAQ 06-0012 Background 5
Generic Fire Modeling Treatments November 6, 2007 1
Overview Define the treatments What are they?
Why were they developed?
What are they used for?
Describe the basis for each treatment Describe the process by which they are applied 2
Generic Fire Modeling Treatments Pre-solved mathematical solutions Simple correlations/zone computer models Conservatively biased/full parameter sensitivity evaluation Range set to accommodate most applications Fully specified limits of applicability for each treatment Eight distinct computation areas Fire scenario and fire scenario effects Developed to allow efficient determination of zone of influence in the field 3
Field Use of Generic Treatments 3-page field note form with procedure Cross-indexes NUREG 6850 Ignition Source Bins with eight generic treatment cases Selects ZOI using a bounding treatment heat release rate bin for the field notes Defines limits of applicability Provides an option for more refined ZOI Consult tables and graphs in generic treatment report Detailed analysis may be required:
Exceed limits of applicability or higher resolution result is needed 4
Oconee Non-Power Operations By:
David Goforth NFPA-805 Technical Manager November 6, 2007 1
Shutdown Risk Management The likelihood of an adverse event is best reduced by maintaining a balance between prevention and mitigation strategies. Shutdown Risk is minimized by implementing a program that contains the following elements outlined in NUMARC 91-06 and Generic Letter 88-17.
- 1. Preserving Shutdown Key Safety functions through Defense in Depth
- 2. Effective Risk Management
- 3. Awareness and planning of High Risk Evolutions
- 4. Appropriate involvement of organizations and disciplines in schedule development and review
- 5. Effective communication of plant status
- 6. Effective control of outage activities 2
FAQ 07-40 The strategy for additional controls/protection of equipment during non-power operations will be based on configurations or Plant Operating States (POS) during the outage where the risk is intrinsically high. The point of the strategy will be to evaluate and manage the risks of a fire, but not necessarily when the plant is more susceptible to an event causing the loss of a key safety function (KSF). Rather, the strategy should address configurations during which there is a high risk associated with the loss of a KSF. This takes into account the consequences of the loss of a KSF, not just the increased likelihood of the loss of a KSF. During periods of low risk normal risk management controls, processes and procedures will be utilized.

Purpose Describe the transition process for Existing Engineering Equivalency Evaluations (EEEEs)
Z Guidance Z Scope Z Adequacy Review Process Z Documentation Z HNP Results / Examples Page 2
Guidance O NEI 04-02 (Reference 2.4) Section 4.1.1 states in part:
The extent to which the pre-transitional fire protection licensing basis can be incorporated into the new NFPA 805 licensing basis is determined by the extent to which the fire protection CLB can be shown to comply with the requirements in NFPA 805. However, exceptions are permitted for the following licensee specific deviations from NFPA 805 requirements:
Z Existing Engineering Equivalency Evaluations [NFPA 805 Figure 2.2]. Note the licensee will review these equivalency evaluations during the transition process to ensure the quality level and the basis for acceptability is still valid.
Page 3
Guidance (Cont)
O Proposed FAQ 07-0033 O EEEEs performed per the appropriate application of current deterministic guidelines (Generic Letter 86-10) and evaluated under 50.59 and/or the Standard License Condition can be transitioned.
O EEEEs are not considered previously approved by the NRC.
Page 4
Scope - Summarized in LAR O Not in Scope - EEEEs which document rated or compliant conditions.
O In Scope-EEEEs which use performance based evaluations.
Page 5
Adequacy Review Process O Process documented in FPIP-0125.
O Review performed by independent FPE.
O EEEEs that dont meet adequacy review Z Can be reworked to meet acceptance criteria.
Z Can be included in transition as a change.
Page 6
Adequacy Review Process (Cont)
O Acceptance Criteria- NEI 02-03, Appendix A
& FAQ 07-033 (Proposed)
Z The engineering evaluation should not be based solely on quantitative risk evaluations.
Z The engineering evaluation should reflect the current plant configuration or bound changing plant conditions.
Page 7
Adequacy Review Process (Cont)
Z The engineering evaluation should be an appropriate use of the engineering evaluation process.
Z The engineering evaluation has been evaluated against the criteria in the pre-transition standard fire protection license condition, 10 CFR 50.59, or plant specific process used to determine the impact of the change/condition on the ability to achieve and maintain post-fire safe shutdown.
Page 8
HNP Results O 34 EEEEs identified for adequacy review O All identified EEEEs performed since 1999.
O 21 identified as adequate during first pass.
O 8 have minor items which need clean up, typos, minor clarifications.
O 5 still under review.
