Dear Sir or Madam:

On March 12, 2012, the NRC issued an order (Reference 1) to Entergy Operations, Inc.

(Entergy). Reference 1 was immediately effective and directs Entergy to install reliable

SFP level instrumentation. Specific requirements are outlined in Attachment 2 of

Reference 1.

Reference 1 required submission of an initial status report 60 days following issuance of

the final interim staff guidance (Reference 2) and an OIP pursuant to Section IV, Condition C. Reference 2 endorses industry guidance document NEI 12-02, Revision 1 (Reference 3). Reference 4 provided the initial status report regarding SFP

instrumentation, and Reference 5 provided the OIP.

Reference 1 requires submission of a status report at six-month intervals following

submittal of the OIP. Reference 3 provides direction regarding the content of the status

reports. The purpose of this letter is to provide the first six-month status report pursuant

to Section IV, Condition C.2, of Reference 1, that delineates progress made in

implementing the requirements of Reference 1. The attached report provides an update

of milestone accomplishments since the last status report, including any changes to the

compliance method, schedule, or need for relief and the basis, if any.

This letter contains no new regulatory commitments. Should you have any questions

regarding this submittal, please contact Stephenie Pyle at 479.858.4704.

I declare under penalty of perjury that the foregoing is true and correct; executed on

August 28, 2013.

Sincerely, Original signed by Jeremy G. Browning JGB/nbm

Attachment to 0CAN081303 Arkansas Nuclear One (ANO) Units 1 and 2 (ANO-1 and ANO-2) First Six Month Status Report for the Implementation of Order EA-12-051, Order to Modify Licenses with Regard to Reliable Spent Fuel Pool (SFP) Instrumentation Attachment to 0CAN081302

ANO-1 and ANO-2 First Six Month Status Report for the Implementation of Order EA-12-051, Order to Modify Licenses with Regard to Reliable SFP Instrumentation Introduction Entergy Operations, Inc. developed an overall integrated plan (OIP) provided via

Reference 1 for ANO-1 and ANO-2, documenting the requirements to install reliable

spent fuel pool instrumentation (SFPI), in response to Reference 2. This attachment

provides an update of milestone accomplishments since submittal of the OIP, including

any changes to the compliance method, schedule, or need for relief/relaxation and the

basis, if any.

Milestone Accomplishments The following milestone(s) have been completed since the development of the OIP (Reference 1) and are current as of July 31, 2013.

Although not part of the original milestone schedule, NRC requests for additional information (RAIs) were received June 26, 2013 (Reference 3) and responded to

on July 25, 2013 (Reference 4). The responses to the RAIs were added to the

milestone schedule. The addition of this milestone and target completion date

does not impact the Order implementation date.

Milestone Schedule Status The following provides an update to the milestone schedule to support the OIP. This

section provides the activity status of each item, and the expected completion date

noting any change. The dates are planning dates subject to change as design and

implementation details are developed.

Milestone Target Completion Date Activity Status Revised Target Completion Date ANO-1 Reliable SFPI Design Modification Package

Developed/Issued October 2013 In Progress ANO-1 Reliable SFPI Installed 1R25 Fall 2014 Refueling Outage Pending 1R25 Early 2015 Refueling Outage (see Note) ANO-2 Reliable SFPI

Design Modification Package

Developed/Issued July 2014 Pending ANO-2 Reliable SFPI Installed 2R24 Fall 2015 Refueling Outage Pending NRC RAIs (Received June 26, 2013)

July 25, 2013 Submitted Not Applicable Attachment to 0CAN081302

Page 2 of 3

Note: The ANO-1 Refueling Outage 1R25 (second refueling outage after submittal of

the OIP) original schedule date of Fall 2014 has slipped to early 2015 due to the 1R24 (Spring 2013) stator drop event recovery and outage extension.

Changes to Compliance Method There are no significant changes to the compliance method as documented in the OIP (Reference 1). OIP changes and/or updates based on current design and

implementation plans are considered minor in nature and are summarized as follows:

Reference OIP Section 2 (Schedule). ANO-1 compliance / implementation /

target completion date has slipped as noted in the above Milestone Schedule

Status. This is a change of the physical date only while maintaining the required

implementation association with the second refueling outage after submittal of

the OIP. Reference OIP Section 6 (Instrument Channel Design Criteria

), Section 7 (Arrangement

), and Attachments 1 and 2 (SFPI Simplified Approximate Locations and Cable Routing

). These sections state that in the SFP area, cables shall be routed in "rigid metal conduit." As already identified in the RAI response (Reference 4), this is updated to "protective metal raceway" to open up the

generic use of raceway (versus conduit) to allow use of wire/tube tracks with

convenient removable covers to better facilitate installation.

Need for Relief/Relaxation and Basis for the Relief/Relaxation ANO expects to comply with the order im plementation date and no relief/relaxation is required at this time.

Open Items from OIP and Draft Safety Evaluation None Potential Draft Safety Evaluation (SE) Impacts The NRC has not issued a draft SE for either unit; therefore, there are no potential

impacts to the draft SE identified at this time.
