Specific requirements are outlined in Attachment 2 of Reference 1 .

Pursuant to Condition C of Section IV, Reference 1 required submission of an initial status report 60 days following issuance of the final interim staff guidance (ISG), an overall integrated plan, and status reports at six-month intervals following the submittal of the overall integrated plan. The ISG (Reference 2) endorses, with clarifications, an industry guidance document from the Nuclear Energy Institute (NEI), NEI 12-06, "Diverse and Flexible Coping Strategies (FLEX) Implementation Guide," Revision 0 (Reference 3). Reference 4 provided the MNGP initial 60-day status report regarding mitigation strategies. Reference 5 provided the overall integrated plan for MNGP. The first through fifth six-month status reports were provided in References 6 through 10, respectively.

The purpose of this letter is to provide the sixth six-month status report pursuant to Section IV, Condition C.2 of Reference 1, which delineates the progress made in implementing the requirements of the Reference 1 Order. The enclosed report provides an update of milestone accomplishments since the Reference 10 status report was submitted, including changes to the compliance method, schedule, or the need and basis for relief, if any.

Please contact John Fields, at 763-271-6707, if additional information or clarification is required.

L-MT-16-009 NSPM Enclosure Monticello Nuclear Generating Plant Sixth Six-Month Status Report for Implementation of Order EA-12-049, Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events 1.0 Introduction The Nuclear Regulatory Commission (NRC) issued Order EA-12-049, "Issuance of Order to Modify Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events," on March 12, 2012 (Reference 1). The Order required licensees to develop, implement and maintain guidance and strategies to maintain or restore core cooling, containment, and spent fuel pool cooling capabilities following a beyond-design-basis external event. The Order required licensees to submit an Overall Integrated Plan (OIP), including a description of how the requirements in of the Order would be achieved. Northern States Power Company, a Minnesota corporation (NSPM), doing business as Xcel Energy, submitted the OIP (Reference 2) for the Monticello Nuclear Generating Plant (MNGP) on February 28, 2013. In accordance with Section IV, Condition C.2 of Reference 1, NSPM submitted the first six-month status report on August 28, 2013 (Reference 3), the second six-month report on February 28, 2014 (Reference 4), the third six-month report on August 28, 2014 (Reference 6), the fourth six-month report on February 24, 2015 (Reference 9) and the fifth six-month report on August 19, 2015 (Reference 10).

On November 25, 2013, the NRC issued an Interim Staff Evaluation (ISE) for MNGP's Mitigating Strategies OIP (Reference 5). The ISE documents the NRC's conclusion that NSPM has provided sufficient information to determine that there is reasonable assurance that the OIP, when properly implemented, will meet the requirements of Order EA-12-049 at MNGP. The ISE also documents the confirmatory and open items identified by the NRC as a result of their review and audit of MNGP's OIP.

This Enclosure provides the sixth six-month status report. This status report includes an update of milestone accomplishments since submittal of the fifth six-month status report, including changes to the compliance method, schedule, or the need and basis for relief, if any. This status report also provides an update on NSPM's closure of the open and confirmatory items identified in the NRC's ISE, if any. This information is current as of January 31,2016.

2.0 Milestone Accomplishments The original milestone schedule with target dates was provided in Attachment 2 of the Reference 2 Enclosure. No milestones were completed since the last six-month status report and prior to January 31, 2016.

L-MT-16-009 NSPM Enclosure 3.0 Milestone Schedule Status The following Table 1 provides an update of the milestone schedule for the OIP. This table includes a brief milestone status and a revised target date, if the target date has changed. The target dates are planning dates subject to change as design and implementation details are developed. This schedule is current as of January 31, 2016.

No activity statuses or target dates have changed for this status report.

• Required dates 4.0 Proposed Changes to Compliance Method There are no additional changes to the compliance methods in the Reference 2 OIP.

No updates to information in the OIP are included in this report.

5.0 Need and Basis for Relief from the Requirements of the Order NSPM expects to comply with the Order implementation date (as described below) and requirements. No relief from the requirements of the Order is required at this time.

On October 1, 2014, NSPM submitted a relaxation request to the NRC for Order EA-12-049 (Reference 7). The relaxation request was proposed because the installation of a containment wetwell vent that meets the requirements of Order EA-13-109, Phase I, will take additional time to complete, as compared to the compliance dates associated with Order EA-12-049. On November 21, 2014, the NRC approved the requested relaxation (Reference 8).

NSPM plans to provide the NRC with a report that full compliance with the EA-12-049 order has been achieved within 60 days after completion of the 2017 refueling outage.

The "Submit Completion Report" milestone is consistent with the current projected completion of the 2017 refueling outage, plus 60 days.

6.0 Open Items from Overall Integrated Plan and Interim Staff Evaluation NSPM did not identify any open items in the MNGP Mitigating Strategies OIP. The OIP contained future actions to ensure compliance with the Order. The future actions were identified internally and are being tracked through NSPM's corrective action program (CAP).

L-MT-16-009 NSPM Enclosure On November 25, 2013, the NRC issued the ISE for MNGP's Mitigating Strategies OIP (Reference 5). As a result of the review and audit of MNGP's OIP, the NRC identified a list of confirmatory and open items that required additional follow-up or resolution.

Subsequently, during the week of November 17, 2014, the NRC held an onsite audit to assess MNGP's readiness for compliance with Order EA-12-049.

NSPM provided a full update to ISE open items and audit questions in a separate letter to the NRC dated October 12, 2015 (Reference 11 ). Subsequent to this letter, the NRC opened an additional item identified as SE 11. NRC sent SE 11 to NSPM in an email dated November 13, 2015 (Reference 12). NSPM will continue to provide information to the NRC via the online reference portal as necessary.

7.0 Potential Interim Staff Evaluation Impacts No potential impacts of ISE updates are proposed in this report.
