U.S. Nuclear Regulatory Commission Page 3 February 28, 2014 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). 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 overall integrated plan pursuant to Section IV, 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 Watts Bar Nuclear Plant, Units 1 and 2 overall integrated plan. On August 2, 2013, the NRC issued a request for additional information (RAI)

(Reference 6) and TVA provided its response on September 6, 2013 (Reference 8).

The NRC issued its Interim Staff Evaluation and RAls regarding TVA's overall integrated plan on November 13, 2013 (Reference 9). On November 22, 2013, TVA provided an initial response to the Reference 9 RAls (Reference 10) and provided an additional RAI follow-up response on January 10, 2014 (Reference 11).

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. TVA submitted the first six-month update on August 28, 2013 (Reference 7).

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 Enclosure provides an update of milestone accomplishments since submittal of the first six-month status report, including any changes to the compliance method or schedule. Response to the Reference 9 RAls will be provided in a separate letter.

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 February 2014.

This attachment provides an update of milestone accomplishments since submittal of the first six-month status report (Reference 4),

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 January 31, 2014.

WBN issued DCN 59683 for SFPLI on September 30, 2013 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.

In the first six-month update dated August 28, 2013 (Reference 3), the target completion dates were revised to reflect implementation of the modifications on-line for Unit 1 and prior to Unit 2 initial startup. The implementation dates are further revised as shown in the column titled Revised Target Completion Date above.

These revised dates fall within the schedule required by NRC Order EA-12-051.

2. These milestones were not included in the February 28, 2013, Overall Integrated Plan.

4 Changes to Compliance Method There are no other changes to the compliance method as documented in the Overall Integrated Plan (Reference 1) and Section 4 of the first six-month update (Reference 7).
