Dear Sir or Madam:

By letter dated July 28, 2011 (Reference 1), Entergy Operations, Inc. (Entergy) received enforcement discretion for fire protection issues for Renewed Facility Operating License No.

DPR-51 for Arkansas Nuclear One, Unit 1 (ANO-1). The enforcement discretion was based, in part, on submittal of an ANO-1 request to adopt a new fire protection licensing basis which complies with the requirements in 10 CFR 50.48(a), 10 CFR 50.48(c), and the guidance in Regulatory Guide 1.205, Risk-Informed Performance-Based Fire Protection for Existing Light-Water Nuclear Power Plants, no later than August 31, 2012.

ANO, Unit 2 (ANO-2) submitted a request to adopt a new licensing basis (i.e., transition to 10 CFR 50.48(c), National Fire Protection Association (NFPA) Standard 805, commonly called NFPA 805) in March 2012. By letter dated May 25, 2012 (Reference 2), the NRC informed Entergy that supplemental information was required to support completion of the NRCs acceptance review of the ANO-2 submittal. As a result, supplemental information, including a regulatory commitment to provide additional information by November 2, 2012, was submitted to the NRC on July 10, 2012 (Reference 3). By teleconference on August 9, 2012, the NRC informed Entergy that additional information would be required to complete the NRC acceptance review and, therefore, the ANO-2 letter would not be accepted. The NRC identified three generic information items, but not in sufficient detail for Entergy to fully comprehend the scope and resources required to resolve all open issues. Subsequently, Entergy applied for an extension of the ANO-2 enforcement discretion period in Reference 4.

From a fire protection perspective, both ANO units are similar and supported by a single NFPA 805 transition team. Given the unexpected and significant resources likely to be required to resolve the aforementioned ANO-2 NFPA 805 submittal issues and, assuming that the same information would need to be developed and submitted for ANO-1, the August 31, 2012, ANO-1 submittal commitment is no longer achievable.

Because additional time is required to better understand the NRC concerns and develop an acceptable response into the ANO-1 submittal, in addition to the development of a subsequent ANO-2 NFPA 805 submittal, Entergy requests an extension of enforcement discretion for fire protection issues associated with ANO-1 until August 31, 2013. Entergy, therefore, commits to submit an ANO-1 License Amendment Request (LAR) implementing 10 CFR 50.48(c) prior to August 31, 2013 (see Enclosure 2 of this letter). Per the enforcement discretion policy, once the request is submitted and accepted, the enforcement discretion would then continue until the NRC dispositions the LAR.

By letter dated May 25, 2012 (Reference 2), the NRC outlined justification that would be required for an extension of enforcement discretion should Entergy be unable to provide sufficient supplemental information in a timely fashion that would support NRC acceptance of the ANO-2 LAR. Enclosure 1 to this letter contains information necessary to meet the Reference 2 requirements for enforcement discretion application as it would pertain to ANO-1.

Entergy requests the NRC issue a Confirmatory Order approving the requested enforcement discretion extension for ANO-1 as permitted by Reference 5.

Should you have any questions concerning this letter, or require additional information, please contact Stephenie Pyle at 479-858-4704.

1CAN081202 Page 3 of 3 I declare under penalty of perjury that the foregoing is true and correct.

Executed on August 23, 2012.

Enclosure 1 to 1CAN081202 Enforcement Policy Requirements for Fire Protection Issues - 10 CFR 50.48(c) to 1CAN081202 Page 1 of 2 Enforcement Policy Requirements for Fire Protection Issues - 10 CFR 50.48(c)

In accordance with Section 9.1, "Enforcement Discretion for Certain Fire Protection Issues (10 CFR 50.48)," of the NRC Enforcement Policy, dated July 12, 2011, and NRC letter to Entergy Operations, Inc. (Entergy) dated May 25, 2012, Supplemental Information Needed for Acceptance of Requested Licensing Action Re: License Amendment Request to Adopt National Fire Protection Association Standard 805 (ML121380395), Entergy is providing the following justification in support of extending the current enforcement discretion period for fire protection issues for Arkansas Nuclear One, Unit 1 (ANO-1) as described in the cover letter to this Enclosure. The required information stated below is excerpted from the aforementioned NRC letter dated May 25, 2012. Key information associated with Entergys NFPA 805 transition process is included in italics.

1. Schedule of the key transition activities and major milestones for achieving the proposed new date including:
a. The preliminary design of specific plant modifications used to reduce site risk.

The preliminary design of specific plant modifications that are necessary to support the ANO-1 transition to NFPA 805 is included in Attachment 1 of this Enclosure.

Physical modifications are generally in the scoping phase at this time; however, the modification design phase includes verification by key ANO NFPA 805 project team personnel to ensure the final design meets the risk-based requirements credited in the ANO-1 NFPA 805 transition process.

b. Identification of all required NFPA 805 operator recovery actions.

Operator recovery actions are provided in Attachment 2 of this Enclosure. Although the final ANO-1 NFPA 805 submittal is not complete, the ANO-1 NFPA 805 transition process is not expected to identify any additional operator recovery actions.

c. Identification of all the NFPA 805 recovery action risk.

Recovery action risk is included in Attachment 3 of this Enclosure. The risk associated with the recovery actions is conservatively calculated within the context of the Fire Area in which the recovery actions are credited. The information provided in Attachment 3 is preliminary; however, Entergy does not expect the enclosed risk values to differ significantly in the final NFPA 805 submittal from that provided in Attachment 3.

d. Completion of the subsequent fire risk evaluations, sensitivity analyses, and formulation of the LAR.

The fire risk evaluations (FREs) and any necessary sensitivity analyses have been completed and are undergoing final review. Completion of the ANO-1 NFPA 805 submittal is not expected to require any significant changes to the fire risk evaluations or sensitivity analyses. However, the scope of the NRC identified ANO-2 open items, which must be evaluated for impacts on the ANO-1 NFPA 805 submittal, could require further review of the FREs and/or sensitivity analyses.

to 1CAN081202 Page 2 of 2 In light of the above, Entergy expects to submit the ANO-1 LAR by August 31, 2013, to accommodate gaps identified in the ANO-2 LAR and to account for unforeseen circumstances that may arise over this time period that could have a significant, currently undefined, impact on the timing of the ANO-1 LAR. Therefore, Entergy requests an extension of enforcement discretion until August 31, 2013. Nevertheless, Entergy intends to submit the ANO-1 LAR as soon as possible and will continue to interface with NRC personnel to support this effort.

2. Transition status should also identify and describe the additional progress that will be made in the following areas between the original ANO-1 LAR submittal date and the proposed new submittal date:
a. Classical fire protection transition.
b. Nuclear safety performance criteria transition.
c. Defining and installing transition modifications.

A summary of the ANO-1 NFPA 805 transition schedule over the requested enforcement discretion extension period is provided in Attachment 4 of this Enclosure.

Note that the uncertainties described above and accommodation of the ANO-2 NFPA 805 submittal can affect the schedule. Issues that have been raised on ANO-2 will need to be addressed for ANO-1 and resolved separately. The schedule is continuously updated to reflect necessary changes in start and finish dates and to reflect current plans.

The aforementioned May 25, 2012, NRC letter also requested Entergy ensure the following transition-related information remains available, on-site, for NRC staff review:

a. Listing of all fire protection-related non-compliances and the related compensatory measures for those non-compliances.
b. Documentation ensuring each Operator Manual Action put in place as a compensatory measure is feasible and reliable, in accordance with the guidance in Regulatory Issue Summary 2005-07, "Compensatory Measures to Satisfy the Fire Protection Program Requirements," dated April 19, 2005 (ADAMS Accession No. ML042360547).
c. A description of the physical modifications performed, if any, to address existing fire protection issues and non-compliances.

The above information is available, on-site, for NRC staff review.

Attachment 2 ANO-1 NFPA Operator Recovery Actions

, Attachment 2 1CAN081202 Page 1 of 3 A multi-compartment analysis has been performed that has identified the need for operator action should the fire impact adjacent areas. These actions are required in the event of a multi-compartment fire interaction. The probability of such an interaction is low and therefore the need to implement these actions is not expected based upon the low failure probability of breaches that affect the associated barriers and creates an interaction beyond the initiating fire requiring recovery actions due to the fire impact in the adjacent area. The incorporation of these actions in post fire shutdown procedures will be evaluated in a manner that clearly differentiates these actions from those primary recovery actions which are associated with the initiating fire. The recovery actions identified below are associated with the initiating fire.
