Draft Request for Additional Information for (MF6061) Regarding TSTF-425, rev. 3 Importance: High Ron and Rick, By letter dated March 26, 2015 (ADAMS Accession No. ML15089A231, Exelon Generation Company, LLC (EGC) submitted a license amendment request (LAR) for Nine Mile Point Nuclear Station Unit No. 1. The proposed amendment would modify NMP, Unit 1 TS by relocating specific surveillance frequencies to a licensee-controlled program with the implementation of Nuclear Energy Institute (NEI) 04-10, "Risk-Informed Technical Specifications Initiative 5b, Risk-Informed Method for Control of Surveillance Frequencies." The changes are consistent with NRC-approved Industry Technical Specifications Task Force (TSTF) Standard Technical Specifications (STS) change TSTF-425, Revision 3, (ADAMS Accession No. ML090850642). The Federal Register Notice published on July 6, 2009 (74 FR 31996),
announced the availability of this TS improvement.
Based on our review of the request, we have identified additional areas where additional information is needed to complete our review. The Draft request for additional information (RAI) is provided in this email. The staff has requested a response by October 22. If you need clarifications, please let me know as soon as possible so I may arrange a call with the staff.
REQUEST FOR ADDITIONAL INFORMATION RELATED TO AN AMENDMENT TO ADOPT TECHNICAL SPECIFICATIONS TASK FORCE TRAVELLER (TSTF)-425 TO RELOCATE SPECIFIC SURVEILLANCE FREQUENCIES TO A LICENSEE CONTROLLED PROGRAM NINE MILE POINT NUCLEAR STATION UNIT 1 DOCKET NO.
50-220
- 1. The license amendment request (LAR) notes that a peer review was performed in 2008 for the internal events PRA. Confirm that this was a full scope peer review. Also, confirm that Regulatory Guide (RG) 1.200, Revision 1 was used, and note which ASME/ANS standard version endorsed by RG 1.200, Revision 1 was used.
- 2. The LAR does not mention that a gap assessment was performed for the internal events PRA between RG 1.200, Revision 1 and RG 1.200, Revision 2. If this has not been done, perform a gap assessment.
Provide the gap assessment findings and observations with their dispositions for the application.
- 3. The LAR states that in performing assessments for other hazards groups, a qualitative or bounding approach will be utilized in most cases. Clarify which hazard groups are included in the other hazards groups. Also, confirm that surveillance test interval evaluations, which are based on Individual Plant Examination for External Event studies, will take into consideration the current plant configuration and operation. In addition, if a detailed quantification is being proposed in the LAR for these hazard groups versus a qualitative or bounding analysis, then Regulatory Guide 1.200, Revision 2 should apply to these PRA models. If this is the case, describe your plans to address RG 1.200, Revision 2 for these PRA models other than the Fire PRA model, which was reviewed against this RG.

- 4. The LAR does not discuss shutdown risk assessment, which is included in NEI 04-10 guidance.
Describe the shutdown risk methodology to be used for NEI 04-10 evaluations.
- 5. Do the failure probabilities of structures, systems, and components modeled in the NMP1 internal events PRA include a standby time-related contribution and a cyclic demand-related contribution?
If not, please describe how standby time-related contribution is addressed for extended intervals.
