Dear Sir or Madam:

On March 12, 2012, the NRC issued an order (Reference 1) to Entergy. Reference 1 was immediately effective and directs Entergy to install reliable spent fuel pool level instrumentation at River Bend Station. Specific requirements are outlined in Attachment 2 of Reference 1.

Aw4

RBG-47385 Page 2 of 3 Reference 1 required submission of an initial status report 60 days following issuance of the final interim staff guidance (Reference 2) and an overall integrated plan pursuant to Section IV, Condition C. Reference 1 also requires submission of a status report at six-month intervals following submittal of the overall integrated plan. Reference 3 provides direction regarding the content of the status reports. Reference 2 endorses industry guidance document NEI 12-02, Revision 1 (Reference 3) with clarifications and exceptions identified in Reference 2. Reference 4 provided the Entergy initial status report regarding spent fuel pool instrumentation. Reference 5 provided the Entergy overall integrated plan.

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 Mr. Joseph Clark, Manager- Licensing, at 225-381-4177.

I declare under penalty of perjury that the foregoing is true and correct; executed on August 28, 2013.

1. Introduction Entergy developed an Overall Integrated Plan (Reference 1 in Section 8) for River Bend Station (RBS), documenting the requirements to install reliable spent fuel pool level instrumentation (SFPI), in response to Reference 2. This attachment provides an update of milestone accomplishments since submittal of the Overall Integrated Plan, 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 the development of the Overall Integrated Plan (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 July 10, 2013 (Reference 3) and responded to on July 25, 2013 (Reference 4). The response to the RAIs was added to the milestone schedule. Any additional RAI responses will be provided in future six-month status reports as necessary. The status of individual RAIs is indicated in the attached RAI table. The addition of this milestone and target completion date does not impact the Order implementation date.

3. Milestone Schedule Status The following provides an update to milestone schedule to support the Overall Integrated Plan.

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.

Revised Target Milestone Date Activity Status Completion Date Reliable SFPI Installed Spring 2015 Refueling In Progress Outage Respond to NRC RAls Dated Jul 26, 2013 See RAI Table July 3, 2013 (Reference 3) y Below

4. Changes to Compliance Method The current Level 2 elevation is now 107'-10 5/16" El. The previous Level 2 elevation was 10 ft. above the top of the spent fuel rack at 94'-10 5/16" El. This differs from the conceptual design RBS initially submitted to the NRC. The Level 2 elevation is raised to 107'-10 5/16" to account for non-special nuclear material stored above 94'-10 5/16" in the Spent Fuel Pool.

5. Need for Relief/Relaxation and Basis for the Relief/Relaxation RBS expects to comply with the order implementation date and no relief/relaxation is required at this time.
6. Open Items from Overall Integrated Plan and Draft Safety Evaluation None.
7. Potential Draft Safety Evaluation Impacts The NRC has not yet issued a draft safety evaluation; therefore, there are no potential impacts to the Draft Safety Evaluation identified at this time.
8. References The following references support the updates to the Overall Integrated Plan described in this attachment.
