414 Nicollet Mall - MP4 Minneapolis, MN 55401 December 17, 2015 L-XE-15-019 ATTN: Document Control Desk U.S. Nuclear Regulatory Commission Washington, DC 20555-0001 Prairie Island Nuclear Generating Plant, Monticello Nuclear Generating Plant Units 1 and 2 Docket 50-263 Dockets 50-282 and 50-306 Renewed License No. DPR-22 Renewed License Nos. DPR-42 and DPR-60 Commitment to Maintain Severe Accident Management Guidelines The Nuclear Energy Institute (NEI) Nuclear Strategic Issues Advisory Committee (NSIAC) recently approved an Industry Initiative to implement and maintain Severe Accident Management Guidelines (SAMGs). This letter establishes Northern States Power Company, a Minnesota corporation (NSPM), d/b/a Xcel Energy, commitments related to SAMGs for the Monticello Nuclear Generating Plant (MNGP) and Prairie Island Nuclear Generating Plant (PINGP). These guidelines would be used by emergency response personnel during accident conditions that progress beyond the mitigation capabilities described in Emergency Operating Procedures (EOPs). SAMG strategies are intended to arrest the progression of fuel damage, maintain the capability of the containment as long as possible, and minimize radiological releases.

It is expected that NRC staff personnel will conduct periodic inspections of the MNGP and PINGP SAMGs and performance deficiencies, if any, will be assessed using the Reactor Oversight Process. NSPM also understands that inspection activities will not extend to NRC review and approval of SAMG strategies, or the use of equipment described in the SAMGs.

Should you have any questions concerning the content of this letter, please contact John Callahan, Manager - Emergency Preparedness, (612) 330-2879.

ENCLOSURE 1 LIST OF REGULATORY COMMITMENTS - PRAIRIE ISLAND NUCLEAR GENERATING PLANT The following table identifies those actions committed to by Northern States Power Company, a Minnesota corporation (NSPM), d/b/a Xcel Energy, for the Prairie Island Nuclear Generating Plant (PINGP). Any other statements in this submittal are provided for information purposes and are not considered to be regulatory commitments.

TYPE (Check One)

SCHEDULED COMMITMENT ONE- COMPLETION CONTINUING DATE TIME COMPLIANCE ACTION NSPM will consider the PINGP X October 31, 2016 SAMGs within plant configuration management processes in order to ensure that the SAMGs reflect changes to the facility over time.

NSPM will update the PINGP X Within 2 refueling SAMGs to future revisions of the outages or 3 years of Pressurized Water Reactor Owners the publication date Group generic severe accident of the guidelines, technical guidelines, and the whichever is greater SAMGs will be integrated with other emergency response guideline sets and symptom-based Emergency Operating Procedures, and validated, using the guidance in NEI 14-01, Emergency Response Procedures and Guidelines for Beyond Design Basis Events and Severe Accidents.
