UNITED STATES NUCLEAR REGULATORY COMMISSION REGION III 2443 WARRENVILLE RD. SUIT E 210 LISLE, IL 60532-4352 March 1, 2017 Mr. Scott Site Vice President Prairie Island Nuclear Generating Plant Northern States Power Company, Minnesota 1717 Wakonade Drive East Welch, MN 55089-9642 SUBJECT: ANNUAL ASSESSMENT LETTER FOR PRAIRIE ISLAND NUCLEAR GENERATING PLANT, UNITS 1 AND 2 (REPORT 05000 282/20 16 00 6 AND 05000 306/2 0 16 00 6)

Dear Mr. Northard:

The NRC has completed its end-of-cycle performance assessment of Prairie Island Units 1 and 2 , reviewing performance indicators (PIs)

, inspection results

, and enforcement actions from January 1, 20 16 , through December 31, 20 16. This letter informs you of the NRC's assessment of your facility during this period and its plans for future inspections at your facility. The NRC concluded that overall performance at your facility preserved public health and safety.

The NRC determined the performance at Prairie Island Unit 1 during the most recent quarter was within the Licensee Response Column, the highest performance category of the NRC

's Reactor Oversight Process (ROP) Action Matrix

, because all inspection findings had very low safety significance (i.e., Green), and all PIs were within the expected range (i.e., Green). Therefore, the NRC plans to conduct ROP baseline inspections at your facility.

The NRC determined the performance at Prairie Island Unit 2 during the most recent quarter was within the Regulatory Response Column, the second highest performance column of the NRC's Reactor Oversight Process (ROP) Action Matrix

. This conclusion was based on one low-to-moderate (White) PI for Unplanned Scrams per 7000 critical hours

.

The NRC's review of Prairie Island Nuclear Generating Plant, Unit 2, identified that Unplanned Scrams per 7,000 Hours PI had returned to below the Green-to-White threshold in the second quarter of 2016. On October 25, 2016, the NRC issued a supplemental inspection report (ML16299A465), which stated that your actions to address the performance issue(s) were acceptable and the PI was closed. Therefore, as a result of the successful completion of the supplemental inspection and a Green Unplanned Scrams per 7,000 Critical Hours PI, the NRC determined the performance at Prairie Island Nuclear Generating Plant, Unit 2, to be within the Licensee Response column of the ROP Action Matrix as of October 25, 2016.

The enclosed inspection plan lists the inspections scheduled through December 31

, 20 17. The NRC provides the inspection plan to allow for the resolution of any scheduling conflicts and personnel availability issues. Routine inspections performed by resident inspectors are not included in the inspection plan. The inspections listed during the last twelve months of the inspection plan are tentative and may be revised. The NRC will contact you as soon as possible to discuss changes to the inspection plan should circumstances warrant any changes.

This inspection plan does not include the plan for security-related inspections, which will be sent via separate, non-publicly available correspondence.

In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 2.390 of the NRC

's "Rules of Practice," a copy of this letter will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Please contact Kenneth Riemer at 630-829-9628 with any questions you have regarding this letter.

Sincerely,

/RA/
