UNITED STATES NUCLEAR REGULATORY COMMISSION rch 2, 2018

SUBJECT:

ANNUAL ASSESSMENT LETTER FOR PERRY NUCLEAR POWER PLANT; REPORT 05000440/2017006

Dear Mr. Hamilton:

The NRC has completed its end-of-cycle performance assessment of your Perry Nuclear Power Plant, reviewing performance indicators (PIs), inspection results, and enforcement actions from January 1, 2017 through December 31, 2017. This letter informs you of the NRCs 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 your Perry Nuclear Power Plant during the most recent quarter was within the Regulatory Response Column of the NRCs Reactor Oversight Process (ROP) Action Matrix. This conclusion was based on a single inspection finding having low-to-moderate safety significance (i.e., White) in the Mitigating Systems Cornerstone originating in the second quarter of 2017 that involved the failure to evaluate the effects of voltage suppression diode failure on the Standby Diesel Generator (SDG) control circuit (Inspection Report 05000440/2017010), and all PIs within the expected range (i.e., Green).

Therefore, in addition to ROP baseline inspections, the NRC commenced a supplemental inspection in accordance with Inspection Procedure 95001, Supplemental Inspection Response To Action Matrix Column 2 Inputs. This procedure was conducted to provide assurance that:

(1) the root and contributing causes of the White performance issue were understood; (2) the extent of condition and extent of cause were identified; and (3) your corrective actions were sufficient to address the root causes and contributing causes and to prevent recurrence. The NRC completed the on-site portion of the supplemental inspection the week of February 12, 2018. The results of this inspection will be communicated in Inspection Report 05000440/2018040.

The enclosed inspection plan lists the inspections scheduled through December 31, 2019. This updated inspection plan now includes planned security inspections which were formerly transmitted under separate correspondence. 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 12 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.

The enclosed inspection plan includes, among other inspections, a Cyber Security Inspection in April 2018 conducted in accordance with Inspection Procedure (IP) 71130.10P, Cyber Security, a Design Basis Assurance inspection in June 2018 conducted in accordance with IP 71111.21N, Design Bases Assurance Inspection (Programs), and a Fire Protection inspection in September 2018 conducted in accordance with inspection procedure IP 71111.05T, Fire Protection (Triennial).

This letter and its enclosure will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding.

Please contact Billy Dickson at 630-829-9827 with any questions you have regarding this letter.

Sincerely,

/RA Julio Lara Acting for/
