Dear Sir or Madam:

On March 12,2012, the Nuclear Regulatory Commission ("NRC" or "Commission")

issued an order (Reference 1) to Grand Gulf Nuclear Station (GGNS). Reference 1 was immediately effective and directs GGNS 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 requires submission of an initial status report 60 days following issuance of the final interim staff guidance. The final interim staff gUidance (Reference 2) was issued August 30, 2012. The purpose of this letter is to provide the initial status report pursuant to Section IV, Condition Co2, of Reference 1 within 60 days following issuance

GNRO-2012/0129 Page 2 of 3 of Reference 2. This report confirms GGNS has received Reference 2 and is in the process of evaluating the guidance for the purpose of establishing mitigation strategies to maintain or restore core cooling, containment, and spent fuel pool cooling capabilities in the event of a beyond-design-basis external event as described in Attachment 2 of Reference 1.

Major activities completed during this reporting period:

• Additional portable equipment was ordered prior to the issuance of Reference 2, as described in an NEI letter to the NRC (Reference 3).

• A site-specific evaluation is in progress to establish the coping capabilities as defined in NEI 12-06 (Reference 4).

• Resources are being identified and project plans initiated, including development of milestones, to assure compliance with Reference 1.

Planned activities for the next six months:

• Development and submittal of the overall integrated plan.

Technical difficulties encountered that could affect the ability to provide the licensee's February 28, 2013, submittal:

• None at this time.

Project milestones schedule through completion of installation and testing:

• A project milestones schedule will be provided with the overall integrated plan.

• Implementation of the order will be completed for GGNS Unit NO.1 prior to startup from Refueling Outage (RFO) Spring 2016.

This letter contains no new regulatory commitments.

If you have any questions regarding this report, please contact Jeffery A. Seiter at 601-437-6299.

I declare under penalty of perjury that the foregoing is true and correct; executed on October 25,2012.
