PEACH BOTTOM ATOMIC POWER STATION - POST-APPROVAL SITE INSPECTION FOR LICENSE RENEWAL - PHASE 4 INSPECTION REPORT 05000277/2018011 AND 05000278/2018011

Dear Mr. Hanson:

On November 30, 2018, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at the Peach Bottom Atomic Power Station, Units 2 and 3 and discussed the results of this inspection with Mr. Matthew Herr, Plant Manager, and other members of your staff. The results of this inspection are documented in the enclosed report.

The inspection examined activities conducted under your license as they relate to safety and compliance with the Commissions rules and regulations and with the conditions of your license.

In conducting the inspection, the team examined a sample of your Aging Management Programs to verify the effects of aging were being managed to ensure structures, systems, and components in the scope of these programs maintained the ability to perform their intended functions. The inspection involved review of your implementing procedures, evaluations, and corrective actions associated with your monitoring activities. The inspection also involved plant equipment walkdowns and interviews with station personnel.

The NRC inspectors did not identify any finding or violation of more than minor significance. This letter, its enclosure, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and the NRC Public Document Room in accordance with Title 10 of the Code of Federal Regulations (10 CFR), Part 2.390, Public Inspections, Exemptions, Requests for Withholding.

Sincerely,

/RA/

SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring Exelons performance at

Peach Bottom Atomic Power Station, Units 2 and 3 by conducting a Post-Approval Site Inspection for License Renewal - Phase 4 in accordance with the Reactor Oversight Process.

The Reactor Oversight Process is the NRCs program for overseeing the safe operation of commercial nuclear power reactors. Refer to https://www.nrc.gov/reactors/operating/oversight.html for more information.

No findings or more-than-minor violations were identified.

INSPECTION SCOPES

This inspection was conducted using the appropriate portions of the inspection procedure in effect at the beginning of the inspection unless otherwise noted. Currently approved inspection procedures with their attached revision histories are located on the public website at http://www.nrc.gov/reading-rm/doc-collections/insp-manual/inspection-procedure/index.html.

Samples were declared complete when the inspection procedure requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter 2515, Light-Water Reactor Inspection Program - Operations Phase. The team reviewed selected procedures and records, observed activities, and interviewed personnel to assess licensee performance and compliance with Commission rules and regulations, license conditions, site procedures, and standards.

REACTOR SAFETY

71003 - Post-Approval Site Inspection for License Renewal - Phase 4

The team selected for evaluation six aging management programs considering risk insights and programs that were enhanced or new under the renewed operating license. The team also considered for selection those programs with monitoring results that were performed for the first time or identified examination or test results not experienced in the past. The inspection performed by the team was conducted as outlined in NRC Inspection Procedure 71003. For the age management programs selected, the team reviewed records, interviewed plant staff, and conducted plant walk downs to evaluate whether age management program elements were being implemented Involving program scope, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, acceptance criteria, corrective actions, confirmation process, administrative controls, and operating experience.

The following age management programs were evaluated by the team:

Q 1.1, Flow Accelerated Corrosion Program

Q 1.16, Maintenance Rule Structural Monitoring Program

Q 2.3, Ventilation System Inspection and Testing Activities

Q 2.5, Outdoor, Buried and Submerged Component Inspection Activities

Q 2.9, Fire Protection Activities

Q 3.5, In-accessible Medium Voltage Cables not subject to 10 CFR 50.49 Environmental Qualification Requirements

EXIT MEETINGS AND DEBRIEFS

The inspectors verified no proprietary information was retained or documented in this report.

On November 30, 2018, the inspectors presented the teams inspection results to Mr. Matthew Herr, Plant Manager, and other members of the licensee staff.
