On March 12, 2012, the Nuclear Regulatory Commission ("NRC" or "Commission") issued an order (Reference 1) to Florida Power & Light (FPL). Reference I was immediately effective and directs FPL/St. Lucie to develop, implement, and maintain guidance and strategies to maintain or restore core cooling, containment, and spent fuel pool cooling capabilities in the event of a beyond-design-basis external event. Specific requirements are outlined in Attachment 2 of Reference 1.
Florida Power & Light Company 6501 S. Ocean Drive, Jensen Beach, FL 34957

L-2013-254 Page 2 Reference I required submission of an Overall Integrated Plan by February 28, 2013. The NRC Interim Staff Guidance (ISG) (Reference 2) was issued August 29, 2012 which endorses industry guidance document NEI 12-06, Revision 0 (Reference 3) with clarifications and exceptions identified in Reference 2. Reference 3 provides direction regarding the content of this Overall Integrated Plan.
Reference 4 provided the FPL/St. Lucie initial status report regarding mitigation strategies, as required by Reference I. Reference 5 provided the FPL/St. Lucie Overall Integrated Plan pursuant to Section IV, Condition C. 1, of Reference 1. Reference 6 informed the NRC that St.
Lucie was no longer pursuing reactor coolant pump (RCP) seal package modifications as part of the FLEX strategy.
The purpose of this letter is to provide the first six-month Overall Integrated Plan status report.
The information in the enclosure is based on conceptual design information that is current as of this letter. As design details and associated procedural guidance are finalized, additional information, as well as revisions to the information contained in the enclosure to this letter, will be communicated to the NRC in the 6-month Integrated Plan updates as required by Reference 1.
This letter contains no new regulatory commitments.

L-2013-254 Enclosure Page 1 of 16 First Six Month Status Report for the Implementation of Order EA-12-049, Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events 1 Introduction Florida Power & Light (FPL) developed an Overall Integrated Plan (Reference I in Section 8); documenting the diverse and flexible strategies (FLEX), in response to Reference 3 for the St. Lucie plant. 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 I). Milestone accomplishments are current as of August 19, 2013.
    . Submittal of August 2013 6-Month submittal (this document) 3     Milestone Schedule Status The following provides an update to Attachment 2 of the Overall Integrated Plan. It provides the activity status of each item, and whether the expected completion date has changed. The dates are planning dates subject to change as design and implementation details are developed. An additional milestone for FLEX Strategy Walkthrough Demonstration has been added per NEI template revision. The revised milestone target completion dates do not impact the order implementation date.

Reference 2 revised the St. Lucie FLEX strategy to maintain the current Flowserve N-9000 RCP seal configuration without making a Flowserve Abeyance seal modification. The existing St. Lucie seal configuration is consistent with the N-9000 RCP seal configuration evaluated in WCAP-17601-P, "Reactor Coolant System Response to the Extended Loss of AC Power Event for Westinghouse, Combustion Engineering and Babcock & Wilcox NSSS Designs" [5] and with the approaches adopted by other Combustion Engineering NSSS plants that currently utilize the Flowserve N-9000 seal. Note that both St. Lucie units have excess flow check valves in the RCP controlled bleed off (CBO) lines and, additionally, have fail closed isolation valves to isolate the CBO leakage pathway. Station Blackout Emergency Operating Procedures , have an early positive step to isolate the CBO leak path on loss of seal cooling.
As part of the revised RCP seal approach, St. Lucie will initiate the reactor coolant system cooldown to a steam generator pressure of 120 psia in a 2-6 hour timeframe as opposed to the 10-14 hour timeframe originally indicated in Reference 1. This action is compliant with WCAP-17601-P and eliminates the deviation previously indicated within Reference I Attachment IB, NSSS Significant Reference Analysis Deviation Table.

L-2013-254 Enclosure Page 3 of 16 4.2    Condenser Makeup Lines The Reference I FLEX response (page 22 of 102) stated that non-seismic condenser makeup lines from the CST would be seismically qualified to provide an additional qualified water inventory for hot standby and cooldown. In a seismic scenario, the qualified contents of the two CSTs and two RWTs will be available to provide approximately 120 hours of Phase 2 coping time. There is reasonable assurance that volumes of one or more non-qualified tanks may also be available. Entry into Phase 3 shutdown cooling (SDC) is expected well before use of makeup of seawater from the Ultimate Heat Sink would be anticipated. Accordingly, the current FLEX strategy does not include a modification to seismically qualify the condenser makeup lines.
4.3    Mechanical Connections The St. Lucie FLEX strategy for making mechanical system connections has evolved from that indicated in Reference I response figures to be consistent with NEI 12-06 guidance (Reference 4). Secondary connections may require reconfiguration (e.g., removal of valve bonnet or disassembly of a flanged pipe joint) if validated that time and resources are reasonably available to support the reconfiguration. Location of the connection points provide reasonable assurance that at least one connection will be available for all applicable hazards.
Refer to attached revised mechanical connection figures.
4.4    Electrical Connections The St. Lucie FLEX strategy for making electrical system connections has evolved from that indicated in the Reference I response figures to be consistent with NEI 12-06 guidance (Reference 4). Refer to attached revised electrical connection figures. Note the 480 volt connections will now be made using procedurally controlled breakers rather than using transfer switches.
4.5    Boration Requirements for Shutdown Margin The Reference 1 FLEX response (page 37 of 102) discussed boration requirements for shutdown margin.
Boration requirements have been developed using a generic analysis to encompass future Fuel Cycles. The analysis determined that SIT injection during the 2-6 hr cooldown to 120 psia SG pressure provides sufficient boration to maintain 1% Shutdown Margin with All Rods In and Xenon free conditions for an RCS cold leg temperature of> 300F. Additional boration is required to maintain 1% Shutdown Margin with All Rods In and Xenon free conditions prior to further cooldown in Phase 3. A Charging Pump will be available in FLEX Phase 2 and 3.
4.6    RRC LUHS Pump The Reference I FLEX response (page 68 of 102) indicated a pump would be provided from the Regional Response Center (RRC) to replace the function of the Intake Cooling Water Pumps due to the Loss of Ultimate Heat Sink (LUHS) event. The design point of the SAFER RRC pump is subject to final

L-2013-254 Enclosure Page 4 of 16 procurement but is expected to be 5000 gpm at 150 psi. The LUHS Pump criteria mentioned in Reference I (page 72 of 102; 7162 gpm, 90 psi) will be altered to align with SAFER provided equipment and demonstrated to be sufficient for the purpose of reinstating Phase 3 Shutdown Cooling.
5    Need for Relief/Relaxation and Basis for the Relief/Relaxation FPL expects to comply with the order implementation date. No relief/relaxation is required at this time.
