Performance Indicator: PP01 Site-Specific FAQ (Appendix D)? Yes FAQ requested to become effective: when approved and after completion of the security computer upgrade.

Question Section NEI 99-02 Guidance needing interpretation (include page and line citation): NA Event or circumstances requiring guidance interpretation:

Indian Point Unit 2 and 3 each have their own security computer, independent of the other unit resulting in a different security indicator for each unit. The station currently reports two separate and distinct security performance indicators, one for Unit 2 and one for Unit 3 In early 2015, a new security computer system will be made operational, which will result in a single site wide system. This site-specific FAQ requests guidance on how to best handle that transition when it occurs.

If licensee and NRC resident/region do not agree on the facts and circumstances explain:

NA Potentially relevant existing FAQ numbers: NA Response Section Proposed Resolution of FAQ The site proposes to maintain two separate security indicators, one for Unit 2 and one for Unit 3.

Future Data Once the site security system is integrated, the security performance indicator for both units will be annotated with a licensee comment indicating that the security system has been combined into a site indicator. Entergy will work with INPO to revise the normalization factors to reflect the new combined system. For future data reporting, the performance indicators, although two separate files, will contain identical information, each reflecting current site performance.

Past Data (prior to site security computer integration)

For historical data presentation, Entergy proposes to maintain two separate indicators (one for Unit 2 and one for Unit 3). The indicator for the Units will reflect the performance of the unit specific security system, up to the point where the system was integrated, at which point the performance line will shift to reflect the new station value. A licensee comment will be Page 1 of 2 Recd from NRC 03/31/2015

FAQ 14-10 Indian Point Security Upgrade included on the indicator stating that data included before the integration date reflects a unit specific value, versus a site specific value.

If appropriate, provide proposed rewording of guidance for inclusion in next revision. None PRA update required to implement this FAQ: No MSPI Basis document update required to implement this FAQ? No.

NRC Response This FAQ discusses the treatment of the Protected Area Security Equipment Performance Index performance indicator (PI) for Indian Points transition from two independent security systems to a single integrated system. The NRC staff agrees with the licensees proposal to maintain two separate indicators for Indian Point Unit 2 and 3 with the understanding that once integrated, the reported data will be identical for the two units. The licensee will report the PI data with revised site normalization factors for each unit once the system is installed with the previous quarters values utilizing the individual unit normalization factors. It is understood that once the new system has operated for four quarters, the PI value independently reported for each unit will be identical.
