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 directed the Vogtle Electric Generating Plant - Units 3 and 4(VEGP 3&4) 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 3 of Reference 1.
Reference 1 required submission of an Overall Integrated Plan within one year after issuance of the final NRC Interim Staff Guidance (Reference 2). Reference 2 endorses industry guidance document NEI 12-06, Revision 0(Reference 3) with clarifications and exceptions identified in Reference 2. VEGP 3&4 has provided the original VEGP 3&4 Overall Integrated Plan (Reference 4) and an updated VEGP 3&4 Overall Integrated Plan (Reference 5).
U. S. Nuclear Regulatory Commission ND-22-0040 Page 2 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 and was followed in developing the enclosed report. The purpose of this letter is to provide the seventeenth 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 status report provides an update of milestone accomplishments since the last six-month update, including any changes to the compliance method, schedule, or need for relief and the basis, if any.
This letter contains no new regulatory commitments. This letter has been reviewed and determined not to contain security-related information.
If you have any questions, please contact Mr. Steven Leighty at 706-848-6790.
Respectfully submitted.
