The purpose of this letter is to provide the fifth six-month status report pursuant to Section IV, Condition C.2, of the March 12, 2012, U.S. Nuclear Regulatory Commission (NRC) order modifying licenses with regards to requirements for mitigation strategies for beyond-design-basis external events, Order EA-12-049, for the Sequoyah Nuclear Plant (SQN), Units 1 and 2 (Reference 1).
On February 28, 2013, the Tennessee Valley Authority (TVA) submitted an Overall Integrated Plan (OIP) in response to Reference 2. On August 28, 2013, TVA provided the first six-month status report to the OIP (Reference 3).
The OIP submitted in Reference 2 employed a strategy using reactor coolant pump (RCP) low leakage seals. TVA revised its strategy to use the existing conventional RCP seals.
This change in RCP seals required a revision to the OIP submitted by Reference 2. Based on a review of TVAs plan, including the first six-month update and information obtained
U.S. Nuclear Regulatory Commission CNL-15-175 Page 3 August 28, 2015 through the mitigation strategies audit process, the NRC concluded in its Interim Staff Evaluation (ISE) that the plan , when properly implemented, will meet the requirements of the Order EA-12-049 (Reference 4). The ISE included open item 3.2.1.6.A that required revision to the Sequence of Events due to use of the conventional RCP seals for reanalysis by the NRC. On February 28, 2014, TVA provided the second six-month status report and revised OIP (Reference 5) which included the required revision to the Sequence of Events due to use of the conventional RCP seals.
On August 28, 2014, TVA provided the third six-month status report (Reference 6) .
Reference 6 noted changes to the pre-staged locations for the current 6900v FLEX Diesel Generators (3 MWe DGs) and the change in the site location for the FLEX Equipment Storage Building .
On February 27 , 2015, TVA provided the fourth six-month status report (Reference 7). This status report provided an OIP update summary section by section including the use of the Condensate Storage Tanks (CSTs) as the primary water source in lieu of the Auxiliary Feedwater Storage Tank (AFWST). In addition , a copy of the SQN OIP updated to February, 2015 was uploaded to the ePortal.
On April 2, 2015, TVA requested an extension for SQN Unit 1 FLEX implementation (Reference 8) to allow deferral of implementation until the Unit 2 required implementation.
This request was granted by the NRC (Reference 9).
The Enclosure of this letter provides a summary of updates to SQN's OIP since the fourth six-month status report.
Two items on the OIP Open Items table remain open (Open Items 13 and 21) . These two open items are listed in the Enclosure. The OIP Milestone Schedule status and target completion dates have been updated as shown in the Enclosure.
There are no new regulatory commitments in this letter. If you have any questions regarding this report, please contact Erin Henderson at (423) 843-7170.
I declare under penalty of perjury that the foregoing is true and correct. Executed on the 28th day of August 2015.

ENCLOSURE TENNESSEE VALLEY AUTHORITY SEQUOYAH NUCLEAR PLANTS FIFTH SIX MONTH STATUS REPORT FOR THE IMPLEMENTATION OF ORDER EA-12-049, ORDER MODIFYING LICENSES WITH REGARD TO REQUIREMENTS FOR MITIGATION STRATEGIESFOR BEYOND-DESIGN-BASIS EXTERNAL EVENTS Introduction Tennessee Valley Authority (TVA) developed an initial Overall Integrated Plan (OIP)
(Reference 1 in Reference section of this enclosure), for Sequoyah Nuclear Plant (SQN),
Units 1 and 2, documenting the diverse and flexible strategies (FLEX), in response to Reference 2. TVA provided the first 6-month status report on August 28, 2013 (Reference 3). A second 6-month update and a revised OIP were provided on February 28, 2014 (Reference 4), and the third 6-month status report on August 28, 2014 (Reference 5). A fourth 6-month status report was submitted to NRC on February 27, 2015 (Reference 6) and an updated OIP was provided to the NRC through the ePortal. This enclosure provides an update of milestone accomplishments since submittal of the fourth 6-month status report, including any changes to the compliance method or schedule.
Milestone Accomplishments The following milestones have been completed since submittal of the fourth 6-month status report, and are current as of August 21, 2015.
- Unit 1 Design Engineering
- Unit 1 Implementation Outage
- Storage Design Engineering
- Implement Training Milestone Schedule The following provides an update to Attachment 2 of the OIP (Reference 4). The activity status of each item is provided, as well as any change to the expected completion date.
The dates are expected dates and are subject to change as design and implementation details are developed.
The revised milestone target completion dates do not impact the order implementation date.

FLEX Mitigation Strategy Update Summary The following is a list of updates made to the information provided since the fourth 6-month status report (Reference 6). A copy of the latest version of the OIP incorporating these changes will be uploaded to the ePortal. Additional discussion and detail are provided in the OIP.
General information:
- The Developmental Reference listing has been updated, a SQN FLEX White Papers section included and TVA Electronic Document Management System (EDMS) numbers referenced to ease retrievable, as needed.
Maintain Core Cooling & Heat Removal:
- The hardened and seismically qualified CSTs serve as the primary source of Steam Generator (SG) makeup water.
- Long term borated water source includes the (refueling water storage tank) RWST Alternate Strategy for maintaining core cooling with SGs not available. The RWSTs are missile protected from their base at plant grade (elevation 706 feet) to a height 3 feet above their base. The tank is fabricated of 5/16 thick SS SA 240 type 304 plate and has horizontal stiffener bands installed. The volume of water protected is 20,000 gallons. The Unit 1 and Unit 2 RWSTs are located on opposite sides of the plant with structures located between the tanks. In the event of a tornado, it is assumed that one RWST would be damaged by a missile, but the other RWST would survive. This is based on a separation distance of 500 feet in the north and south direction and the robust concrete structures located between the two tanks. These structures include the Reactor Buildings (height of 856.5'), Auxiliary Building (796.75), and the Control Building (755) that provide shielding and separation between the RWSTs (749.7).
Other structures around the RWSTs that would provide a level of protection from tornado generated missiles include for Unit 1, the Unit 1 Primary Water Storage Tank to the east and the Service Building to the west; for Unit 2, the Unit 2 Primary Water Storage to the east and the Condensate Storage Tank shield wall to the west. TVA calculation for structural integrity analysis of the RWSTs is CEB-CQS-295. This calculation verifies structural integrity of the tank under static and dynamic loading.
Maintain RCS Inventory Control:
- Identified revised reactor coolant pump (RCP) seal leakage rates based on PWROG/Westinghouse calculations. Based on the identified RCP seal leakage rates, there is no change to the strategy.
Maintain Spent Fuel Pool Cooling:
- The plant modification to add two independent spent fuel pool (SFP) level instruments which provide remote SFP level monitoring capability is complete. There are no open items relative to NRC Order EA 12-051 and NEI 12-02.

Safety Functions Support:
- Each 480v FLEX diesel generator (DG) is provided with a 180 gallon day tank. Each day tank will provide approximately 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> of 480v FLEX DG full load operation.
Makeup for the 480v FLEX DGs day tanks will be provided by a dedicated 8,000 gallon fuel oil storage tank located at ground level on the South side of the Unit 2 Control and Auxiliary Buildings. Each 480v FLEX DG has a dedicated fuel oil transfer pump located in the fuel oil storage tank, powered by its FLEX DG. Diesel fuel makeup to the 480v FLEX DG day tanks will require manual operator actions on a 7 to 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> periodicity to start the fuel transfer pumps and shut them off when day tank levels are full.

Items that remain Open from Overall Integrated Plan (OIP) and NRC Evaluation The following table provides a summary of the OIP open items that remain Open. The complete OIP Open Items listing is provided in the uploaded OIP.
Open Item Description Status Number 13 An evaluation of the impact of FLEX response Open actions on design basis flood mode preparations TVA River Operations will be performed. This evaluation will include the procedure RvM-SOP-10.05.06, potential for extended preparation time for FLEX.
