Dear Sir or Madam:

By letter dated August 16, 2012 (Reference 1), violations for Indian Point Nuclear Generating Unit No. 2 (IP2) and Unit No. 3 (IP3) were issued for the use of unapproved operator manual actions (OMAs) to mitigate safe shutdown equipment malfunctions caused by a fire-induced single spurious actuation in lieu of protecting the equipment in accordance with 10 CFR Part 50 Appendix R, Paragraph III.G.2. The violations resulted from the denial of a number of OMAs in the Exemption transmitted by letters dated February 1,2012 (References 2 and 3). In accordance with 10 CFR 2.201, Attachments 1, 2, and 3 to this letter provide the reply to the violations. Entergy Nuclear Operations, Inc. (Entergy) is not contesting the violations.

Note that in response to Reference 4, the planned resolutions to eliminate the need for the unapproved OMAs were provided in tables in Reference 5, which were subsequently updated in References 6 and 7. This reply to the notices of violation supersedes the information, including the commitment, previously transmitted in References 5, 6, and 7.

The tables in References 6 and 7 have been provided in Attachments 2 and 3 of this reply with the following changes:

" For both units, the titles of the tables have been changed.

• For IP2 (Attachment 2), the changes in the description under Planned Resolution and Scheduled Completion Date for resolution of OMA 6 in Fire Area F, Fire Zones 5A, 6, and 22A is based on further engineering evaluation leading to the conclusion that modification of the safe-shutdown analysis and methodology only for these three zones within Fire Area F, with no other plant changes, would not be consistent with the existing licensing basis for III.G.2 compliance based on fire areas. Therefore, an integrated solution for OMA 6, encompassing all affected zones in Fire Area F - which involves the need for physical modification - will be implemented, consistent with the schedule shown for OMA 6 in Fire Zones 7A and 27A.

" For IP2 (Attachment 2), the change in Scheduled Completion Date for resolution of OMA 13 in Fire Area J, Fire Zone 43A is based on confirmation of the need to align the solution for this zone with that of adjoining Fire Zone 46A, such that the revised safe-shutdown methodology developed for Fire Zone 46A, scheduled for completion in Q4 2012, will also envelope that of the adjoining Fire Zone 43A.

As noted in Reference 5, given the substantial technical challenge imposed by the OMA resolution effort, and recognizing that the requisite engineering evaluations are in progress at this time, the presently conceptualized solutions may change, in that the scope of analyses and/or the nature and scope of plant physical modifications may require revision as the OMA resolutions are finalized. The target completion dates shown in the attachments represent Entergy's current informed projection, and any change in resolution concept and/or completion schedule that may be determined to be

NL-12-122 Docket Nos. 50-247 & 50-286 Page 3 of 3 necessary as an outcome of the engineering analysis and evaluation process will be communicated to NRC.

Regulatory commitments made in this submittal are identified in Attachment 4 to this letter.

Indian Point Nuclear Generating Unit Nos. 2 & 3 Docket Nos. 50-247 & 50-286 License Nos. DPR-26 & DPR-64

NL-12-122 Docket Nos. 50-247 & 50-286 Attachment 1 Page 1 of 5 Reply to Notices of Violation Regarding Unapproved III.G.2 Operator Manual Actions As transmitted by letters dated February 1,20121, exemptions from the requirements of 10 CFR 50, Appendix R, Paragraph III.G.2 for the use of operator manual actions (OMAs) were granted in part and denied in part for Indian Point Unit 2 (IP2) and Unit 3 (IP3). As a result, a violation was issued for each unit for the use of OMAs without prior NRC approval. The reply provided herein together with Attachments 2 and 3 to this letter address both violations.

Unit 2 Violation License Condition 2.K specifies, in part, that Entergy Nuclear Operations, Inc., (ENO) shall implement and maintain in effect all provisions of the NRC-approved fire protection program as described in the Updated Final Safety Analysis Report.

The Updated Final Safety Analysis Report, Section 9.6 specifies that ENO will meet the requirements of 10 CFR Part 50, Appendix R, Section III.G.2, which requires, in part, except as provided for in paragraph G.3 of this section, where cables or equipment, including associated non-safety circuits that could prevent operation or cause maloperation due to hot shorts, open circuits, or shorts to ground, of redundant trains of systems necessary to achieve and maintain hot shutdown conditions are located within the same fire area, one of the means of ensuring that one of the redundant trains is free of fire damage shall be provided, per the requirements in G.2.a - G.2.f.

Contrary to the above, between June 30, 2006, and April 26, 2012, ENO failed to implement all provisions of the approved fire protection program. Specifically, the safe shutdown strategy for Indian Point Unit 2 relied upon unapproved operator manual actions to mitigate post-fire safe shutdown equipment malfunctions caused by a single spurious actuation, in lieu of protecting the equipment in accordance with 10 CFR Part 50 Appendix R, Section III.G.2, per the requirements in G.2.a - G.2.f . The specific operator manual actions and fire areas and fire zones that are in violation of Appendix R,Section III.G.2 are listed in the Indian Point Unit 2 Denied OMA Summary Table of NRC Inspection Report 05000247/2012009 and 05000286/2012008. The use of manual actions in lieu of providing the required protection requires prior NRC approval.

Unit 3 Violation License Condition 2.H specifies, in part, that Entergy Nuclear Operations, Inc., (ENO) shall implement and maintain in effect all provisions of the approved Fire Protection Program as described in the Final Safety Analysis Report.

NRC letter dated February 1, 2012, "Indian Point Nuclear Generating Unit No. 2 - Exemption from the Requirements of 10 CFR Part 50, Appendix R, Paragraph III.G.2 (TAC No. ME0798)" and NRC letter dated February 1, 2012, "Indian Point Nuclear Generating Unit No. 3 - Exemption from the Requirements of 10 CFR Part 50, Appendix R, Paragraph III.G.2 (TAC No. ME0799)"

NL-12-122 Docket Nos. 50-247 & 50-286 Attachment 1 Page 2 of 5 The Final Safety Analysis Report, Section 9.6.2 specifies that ENO will meet the requirements of 10 CFR Part 50, Appendix R, Section III.G.2, which requires, in part, except as provided for in paragraph G.3 of this section, where cables or equipment, including associated non-safety circuits that could prevent operation or cause maloperation due to hot shorts, open circuits, or shorts to ground, of redundant trains of systems necessary to achieve and maintain hot shutdown conditions are located within the same fire area, one of the means of ensuring that one of the redundant trains is free of fire damage shall be provided, per the requirements in G.2.a - G.2.f.

Contrary to the above, between June 30, 2006 and April 26, 2012, ENO failed to implement all provisions of the approved fire protection program. Specifically, the safe shutdown strategy for Indian Point Unit 3 relied upon unapproved manual operator actions to mitigate post-fire safe shutdown equipment malfunctions caused by a single spurious actuation, in lieu of protecting the equipment in accordance with 10 CFR Part 50 Appendix R, Section III.G.2, per the requirements in G.2.a - G.2.f . The specific operator manual actions and fire areas and fire zones that are in violation of Appendix R,Section III.G.2 are listed in the Indian Point Unit 3 Denied OMA Summary Table of NRC Inspection Report 05000247/2012009 and 05000286/2012008. The use of manual actions in lieu of providing the required protection requires prior NRC approval.

Reason for the Violations 10 CFR 50, Appendix R, Paragraph III.G.2 requires the following:

Except as provided for in paragraph G.3 of this section, where cables or equipment, including associated non-safety circuits that could prevent operation or cause maloperation due to hot shorts, open circuits, or shorts to ground, of redundant trains of systems necessary to achieve and maintain hot shutdown conditions are located within the same fire area outside of primary containment, one of the following means of ensuring that one of the redundant trains is free of fire damage shall be provided:

a. Separation of cables and equipment and associated non-safety circuits of redundant trains by a fire barrier having a 3-hour rating. Structural steel forming a part of or supporting such fire barriers shall be protected to provide fire resistance equivalent to that required of the barrier;

b. Separation of cables and equipment and associated non-safety circuits of redundant trains by a horizontal distance of more than 20 feet with no intervening combustible or fire hazards. In addition, fire detectors and an automatic fire suppression system shall be installed in the fire area; or

c. Enclosure of cable and equipment and associated non-safety circuits of one redundant train in a fire barrier having a 1-hour rating, In addition, fire detectors and an automatic fire suppression system shall be installed in the fire area;

NL-12-122 Docket Nos. 50-247 & 50-286 Attachment 1 Page 3 of 5 Inside noninerted containments one of the fire protection means specified above or one of the following fire protection means shall be provided:

d. Separation of cables and equipment and associated non-safety circuits of redundant trains by a horizontal distance of more than 20 feet with no intervening combustibles or fire hazards;

e. Installation of fire detectors and an automatic fire suppression system in the fire area; or

f. Separation of cables and equipment and associated non-safety circuits of redundant trains by a noncombustible radiant energy shield.

As discussed in the Exemptions transmitted by the February 1, 2012 NRC letters, the NRC staff denied a number of the requested exemptions based on the lack of fire protection defense-in-depth, particularly detection or automatic suppression, or lack of adequate time margin available to complete the OMA.

Entergy requested exemptions because the criteria of III.G.2 were not met, including the lack of detection and/or automatic fire suppression in many of the areas. The areas lacking detection and/or automatic fire suppression were identified in the various submittals, and it was Entergy's belief that the lack of detection/suppression was acceptable as long as the OMAs were demonstrated to be reliable and feasible. Entergy misjudged the significance that the lack of detection/suppression has on the acceptability of using the unapproved OMAs in lieu of meeting the requirements of III.G.2.

For those OMAs that were denied due to inadequate time margin to complete the action, it was Entergy's judgment that the time margins available were adequate, which made the OMAs feasible. This is supported by the determination during inspections performed in May 2011 and again in April 2012 by Region I that the OMAs (except for an IP3 OMA involving service water strainers) are adequate as interim compensatory actions and are feasible. However, considering the scope or complexity of the actions that had to be performed, it was determined by the NRC staff that the OMAs could not be performed with adequate time margin to be acceptable for compliance with Appendix R.

Entergy understands the positions established by the NRC staff and does not contest the violations. Note that the condition reports tracking the resolution of these issues are CR-IP2-2011-02417 and CR-IP3-2011-02853 for IP2 and IP3, respectively.

Regarding the aspect of the IP2 violation where Entergy failed to identify and request exemptions for two OMAs associated with the operation of 21 Charging Pump (operating the pump from the emergency control station in the 480V Switchgear Room and using the scoop tube in the pump room) that were being relied upon to achieve and maintain safe shutdown in the event of a fire impacting Fire Zone 7A in Fire Area F, the following has been determined:

NL-12-122 Docket Nos. 50-247 & 50-286 Attachment 1 Page 4 of 5

" A screening report that identified all the OMAs that required an exemption correctly identified that certain actions associated with 21 Charging Pump would require an exemption, but did not explicitly identify the two OMAs of concern. The input to the engineering report was the IP2 Appendix R Analysis and associated database. The database and document did not correctly record and code the actions for the pump as manual actions. Specifically, non-standard nomenclature was used in the IP2 Appendix R Analysis and multiple protective actions were grouped as a single entry for the pump instead of individually. The use of non-standard nomenclature and presentation method resulted in an error of omission in transcribing OMAs from the screening report to the exemption request submitted in March 2009.

• The personnel responsible for preparing the IP2 Appendix R Analysis database did not exhibit a heightened awareness of the importance of maintaining the convention of the database. The erroneous database entries were obviously different from other entries in the database and should have been questioned before becoming part of the permanent record.

Corrective Steps Taken and Results Achieved Entergy was initially informed of the pending denial of a number of OMAs in May 2011 during the IP3 Triennial Fire Protection inspection. Following receipt of the verbal notification, the following actions were taken for IP2 and IP3:

" Hourly fire watch tours were implemented for all areas in which OMAs were credited, not only for areas in which the denied OMAs were credited. For OMAs in the IP2 Containment, a one hour log of containment average temperature was initiated. These actions will remain in effect for each unapproved OMA until the OMA is resolved.

• In May 2011 during the IP3 Triennial Fire Protection inspection, Region I inspectors assessed the feasibility (including time margins) of the IP2 and IP3 OMAs and determined they were adequate as interim compensatory actions pending final disposition of the exemption requests (except for an IP3 OMA involving service water strainers).

Resolution plans have been established for all of the unapproved OMAs. For IP2, planned resolutions to eliminate the need for the unapproved OMAs are scheduled to be completed as shown in Attachment 2. For IP3, planned resolutions to eliminate the need for the unapproved OMAs are scheduled to be completed as shown in Attachment 3; OMAs 2, 3, 4, 5, 6, 7, 8, and 11 have been resolved by revision of the Appendix R safe-shutdown analysis and methodology to credit existing separation within the fire area/zone, and they are shown as "Completed" in .

Regarding the aspect of the IP2 violation where Entergy failed to identify and request exemptions for the two OMAs associated with the operation of 21 Charging Pump, the following corrective actions as documented in CR-IP2-2012-03024 have been taken:

NL-12-122 Docket Nos. 50-247 & 50-286 Attachment 1 Page 5 of 5 Compensatory measures were verified to be established and adequate to address the OMAs for the operation of the pump, and Operations procedure 2-ONOP-FP-001 (Plant Fires) was revised to include the OMAs.

The feasibility and reliability of the OMAs were validated with Operations and documented by engineering evaluation.

All of the component protection remarks in the IP2 Appendix R Analysis and the IP3 Appendix R Analysis not coded using conventional nomenclature were reviewed and it was verified that there are no other "unaccounted for" manual actions identified in any of the remarks.

Coaching was provided to applicable engineering staff to reinforce the critical nature of the Safe Shutdown Analysis and continued use of Human Performance tools; coaching was provided to the Programs & Components Engineering department to reinforce the use of Human Performance tools when relying on past reports as a basis for critical decisions.

Corrective Steps That Will be Taken Planned resolutions to eliminate the need for the unapproved OMAs are scheduled to be completed as shown in Attachment 2 for IP2 and in Attachment 3 for IP3. As reflected in these attachments, full compliance with the requirements of Appendix R Paragraph III.G.2 will be accomplished by Spring 2014 RFO for IP2 and by Q2 2013 for IP3.

Regarding the aspect of the IP2 violation where Entergy failed to identify and request exemptions for two OMAs associated with the operation of 21 Charging Pump, a modification to protect circuits of concern is required (identified in Attachment 2 as OMAs 20 and 21).
