UNITED STATES NUCLEAR REGULATORY COMMISSION REGION III 2443 WARRENVILLE RD. SUITE 210 LISLE, ILLINOIS 60532-4352 January 5, 2018 Mr. David B.

SUBJECT:
PERRY NUCLEAR POWER PLANTNOTIFICATION OF NRC SUPPLEMENTAL INSPECTION (95001) AND REQUEST FOR INFORMATION
Dear Mr. Hamilton:
By letter dated August 24, 2017, (ADAMS ML17236A187), the U.S. Nuclear Regulatory Commission (NRC) communicated to you the final significance determination of a finding having low-to-moderate safety significance (White) at your Perry Nuclear Power Plant. This finding involved the licensees failure to evaluate the effects of voltage suppression diode failure on the Standby Diesel Generator (SDG) control circuit, which was a component subject to the requirements of Title 10 Code of Federal Regulations (CFR) Part 50, Appendix B, Criterion III, Design Control. Specifically, the licensee failed to consider the effect of a shorted diode on the control circuitry of the SDG, and, as a result, failed to recognize that installation of voltage suppression diodes across control relays, with no mitigation for diode failure, was not suitable for the SDG control circuit. This introduction of new components (diodes) into the control circuitry resulted in the eventual failure of the SDG control circuit, thereby rendering the SDG inoperable and unable to start.
By letter dated October 31, 2017, we were notified by your staff that you were ready for the NRC to conduct our supplemental inspection to review the actions taken to address the White finding. Accordingly, we plan to conduct a supplemental inspection, beginning on February 12, 2018, at your Perry Nuclear Power Plant using Inspection Procedure 95001, Supplemental Inspection for One or Two White Inputs in a Strategic Performance Area. This on-site inspection is scheduled to be performed February 12 through February 16, 2018.
In order to minimize the impact to your on-site resources and to ensure a productive inspection for both organizations, we have enclosed a request for documents needed for this inspection.
The documents identified are those that the inspectors will need prior to and upon arrival at the site. It is important that all of these documents are up-to-date and complete in order to minimize the number of additional documents requested during the on-site portion of the inspection.
We have discussed the schedule for these inspection activities with your staff and understand that our regulatory contact for this inspection will be Mr. Anthony Kledzik. If there are any questions about this inspection or the material requested, please call or email Mr. Jandovitz at 630-829-9763 or John.Jandovitz@nrc.gov.
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.
Sincerely,
/RA/
