Ladies and Gentlemen:
On March 12, 2012, the Nuclear Regulatory Commission (NRC) issued an order (Reference 1) to Southern Nuclear Operating Company. Reference 1 was immediately effective and directs the Vogtle Electric Generating Plant - Units 1 and 2 (VEGP) 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.
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.1.a of Reference 1. Reference 2 endorses industry guidance document NEI 12-06, Revision 0 (Reference 3) with clarifications and exceptions identified in Reference 2.
U.S. Nuclear Regulatory Commission NL-14-0181 Page 2 Reference 4 provided the VEGP initial status report regarding mitigation strategies.
Reference 5 provided the VEGP 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 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 enclosed 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 NRC commitments. If you have any questions, please contact John Giddens at 205.992.7924.

- The licensee stated that the Class 1E batteries are capable maintaining critical loads for 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> prior to reaching the minimum voltage during an ELAP event, with margin. However, on page 10 of the Integrated Plan the licensee stated that the 480V Flex DGs will be available at any point past 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> to restore power to one battery charger on each Class 1 E 125Vdc distribution bus. The licensee's response does not address the additional 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> that the critical loads would be powered from the Class 1E batteries and whether the minimum voltage would be exceeded during this time.

- 1. A structure to provide protection of the FLEX equipment will be constructed to meet the requirements identified in NEI 12-06 Section 11. Construction of the FLEX Storage Facility will be completed for 2 sets of FLEX equipment by the date the first unit will reach the Order EA-12-049 implementation completion due date.
- 2. Based on updated calculations:
- a. The ability to monitor 2 (redundant) channels of instruments is reduced from 16 to 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br /> only in the event the FLEX DG is not installed and operating as planned and expected per the OIP. The ability to monitor a single channel extends past 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br /> without the FLEX DG installed.
- b. The SFP water inventory heat up rates for the maximum normal design basis heat load has been adjusted from 130°F to 212°F after 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> to 100°F to 212°F after 14 hours1.62037e-4 days <br />0.00389 hours <br />2.314815e-5 weeks <br />5.327e-6 months <br />.
- c. The time to boil following an emergency design basis heat load (full core offload) has been adjusted from 5 to 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />. The time to reach the minimum safe shielding water coverage of 15 feet above the top of irradiated fuel has been adjusted from approximately 25 hours2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br /> to approximately 27 hours3.125e-4 days <br />0.0075 hours <br />4.464286e-5 weeks <br />1.02735e-5 months <br />. The acceptability of the initiation of phase 2 actions at approximately 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> due to SFP evaporation has been adjusted from less than 3 feet to less than 2 feet.

- d. The projections for the control room to surpass 11 OoF have been adjusted from less than 9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> to less than 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.

The time for load shed actions outlined in plant procedures to provide reliable illumination in the control room horseshoe area has been adjusted from more than 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br /> to more than 15 hours1.736111e-4 days <br />0.00417 hours <br />2.480159e-5 weeks <br />5.7075e-6 months <br />.
- e. The temperature heat up in the TDAFW pump room with no ventilation has been adjusted from no more than 121 oF during the 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> SBO coping period to no more than 116°F during the first 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> of operation.
- 3. No Phase 1 or Phase 2 coping strategies are required for maintaining containment integrity if the BDBEE occurs while the plant is operating in Modes 1 through 4.
- 4. A Phase 1 coping strategies will be required for maintaining containment integrity if the BDBEE occurs during operating Modes 5 and 6 with steam generator heat removal not available. Containment venting utilizing the ILRT penetration or acceptable alternative provides this containment coping strategy.
- 5. Opening the large missile shield doors is no longer credited for SFP area venting.
- 6. SNC is in the process of evaluating Phase 3 strategies and timing; any changes in Phase 3 strategies will be reflected in a future six month status report.
