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. Reference 6 provided the first six-month status report. The purpose of this letter is to provide the second 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 February 27, 2014.

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

Attachment to 0CAN021406 Page 1 of 5 ANO-1 and ANO-2 Second Six Month Status Report for the Implementation of Order EA-12-051, Order to Modify Licenses with Regard to Reliable SFP Instrumentation

1. 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 SFP instrumentation (SFPI), in response to Reference 2. This attachment provides an update of milestone accomplishments since the last status report, including any changes to the compliance method, schedule, or need for relief/relaxation and the basis, if any.

2. Milestone Accomplishments The following milestone(s) have been completed since August 28, 2013, and are current as of January 31, 2014:

Although not part of the original milestone schedule, the NRC Interim Safety Evaluation (ISE) was received October 29, 2013 (Reference 3). The ISE included 17 requests for additional information (RAIs) for the NRC to complete its review. The NRC clarified during the November 26, 2013, public meeting that the ISE questions supersede any previous requests for information issued by the Staff concerning the SFP instrumentation (Reference 4). Therefore, the RAIs received June 26, 2013 (Reference 5) are considered superseded by the RAIs contained in the ISE received October 29, 2013.

3. 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.

September 30, 2014 In Progress Target Completion Date is the last submitted date from either the overall integrated plan or previous six-month update.

4. Changes to Compliance Method There are no additional changes to the compliance method.

5. Need for Relief/Relaxation and Basis for the Relief/Relaxation Entergy expects to comply with the order implementation date and no relief/relaxation is required at this time.

6. Open Items from OIP and ISE As discussed in Section 2, Entergy has received an ISE for ANO that includes 17 RAIs.

Responses to the RAIs are due September 30, 2014, and are provided in Section 9 of this six-month status report. The following table provides a status of the RAIs.

9. Responses to two of the ISE RAIs for ANO-1:

RAI #4: Please provide the results of the evaluation performed to ensure that other hardware stored in the SFP cannot adversely interact with the SFP level instrumentation.

For ANO-1, the new instruments are being mounted in the east and west corners on north side of the SFP to take advantage of missile and debris protection inherent in the corners of the SFP and from SFP curbs and SFP bridge tracks/rails. Current plant procedures and practices would not result in a need to move spent fuel into these locations either during insertion or removal of spent fuel. Normal activities associated with the SFP racks would not be impacted by mounting the instruments in these locations. An exclusion zone of two square feet around the probe is the minimum clearance required to prevent any tools or devices from disturbing the function of the probe.

RAI #11: Please provide the NRC staff with the final configuration of the power supply source for each channel so that the staff may conclude that the two channels are independent from a power supply assignment perspective.

For ANO-1, the primary channel (Instrument Channel 3) 120 volt alternating current (VAC) power is being supplied from Panel RS3, which is a Class 1E inverter-backed panel supplied from 125V direct current (VDC) Bus D01. The backup channel (Instrument Channel 4) 120 VAC power is being supplied from Panel RS4, which is a Class 1E inverter-backed panel supplied from 125 VDC Bus D02.
