U.S. Nuclear Regulatory Commission Page 2 August 28, 2013 On March 12, 2012, the Nuclear Regulatory Commission (NRC) issued an order (Reference 1)to Tennessee Valley Authority (TVA). Reference 1 was immediately effective and directs TVA to install reliable spent fuel pool level instrumentation (SFPLI). The specific requirements are outlined in Attachment 2 of Reference 1.Reference I 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 V, Condition C. Reference 2 endorses industry guidance document Nuclear Energy Institute (NEI)12-02, Revision 1 (Reference
- 3) with clarifications and exceptions identified in Reference 2.Reference 4 provided the TVA initial status report regarding SFPLI strategies.
Reference 5 provided the TVA Browns Ferry Nuclear Plant, Units 1, 2, and 3 overall integrated plan.Reference 1 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. 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 enclosed report provides an update of milestone accomplishments since submittal of the overall integrated plan, including any changes to the compliance method or schedule.The enclosure describes the plans that TVA will use to meet the regulatory requirements outlined in Attachment 2 of Reference 1, but does not identify any additional actions to be taken by TVA. Therefore, this letter contains no regulatory commitments.
If you have any question regarding this submittal, please contact Kevin Casey at (423) 751-8523.I declare under penalty of perjury that the foregoing is true and correct. Executed on the 28th day of August 2013.Res ec ully, J. W. Shea Vice President, Nuclear Licensing

ENCLOSURE I Introduction Browns Ferry Nuclear Plant (BFN) developed an Overall Integrated Plan (Reference 1 in Section 8 of this Enclosure), documenting the requirements to install reliable spent fuel pool level instrumentation (SFPLI), in response to Reference
- 2. This enclosure provides an update of milestone accomplishments since submittal of the Overall Integrated Plan, including any changes to the compliance method or schedule.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 30, 2013.* A design kickoff meeting has been completed.
- Response to BFN Request for Additional Information (RAI) is complete (Reference 3).3 Milestone Schedule Status The following updates the 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.
The milestone target completion dates do not impact the order implementation date.Page 1 of 4 Target Revised Milestone Completion Activity Target Date Status Completion Date_ Date Submit 60 Day Status Report 10/29/2012 Complete Submit Overall Integrated Plan 02/28/2013 Complete Submit 6 Month Updates: Update 1 08/28/2013 Complete Update 2 02/28/2014 Not Started Update 3 08/28/2014 Not Started Update 4 02/28/2015 Not Started Update 5 08/28/2015 Not Started Update 6 02/282016 Not Started Update 7 08/28/2016 Not Started RAI response 07/18/2013 Complete Modifications:

The original target completion dates for implementation for Units 1, 2, and 3 corresponded to the completion of the second refueling outage of the respective unit following submittal of the February 28, 2013 integrated plan. Implementation of the SFPLI is currently scheduled to be performed on-line as indicated by the revised target completion dates.2. These milestones were not included in the February 28, 2013, Overall Integrated Plan.4 Changes to Compliance Method The primary and backup instrument channel battery life was anticipated to exceed 96 hours0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> in the February 2013 Integrated Plan. A preliminary battery life calculation has been completed.
TVA is updating the anticipated battery life to 84 hours9.722222e-4 days <br />0.0233 hours <br />1.388889e-4 weeks <br />3.1962e-5 months <br /> to provide margin for issues that may arise during the design process.There are no other changes to the compliance method as documented in the Overall Integrated Plan (Reference 1).Page 2 of 4 5 Need for Relief/Relaxation and Basis for the Relief/Relaxation Browns Ferry Nuclear Plant (BFN) 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 NRC Evaluation The following tables provide a summary of the open items documented in the Overall Integrated Plan or the NRC Evaluation and the status of each item.Overall Integrated Plan Open Item Status 01-1) TVA will complete an instrument channel Engineering and vendor uncertainty calculation and document instrument documentation are in progress.channel accuracy and calibration requirements.
