SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at Perry Nuclear Power Plant 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.
List of Findings and Violations
No findings or violations of more than minor significance were identified.
Additional Tracking Items
None.
PLANT STATUS
The plant began the inspection period shutdown for refueling outage (RFO) 1R17. On April 5, 2019, at 5:16 a.m., the plant was placed in startup mode and achieved criticality at 7:25 a.m. that same day. On April 6, 2019, at 11:59 p.m., the main generator was synchronized to the grid. On April 7, 2019, at 2:44 a.m., the main generator was removed from the grid due to hydraulic oil intrusion into the generator casing. On April 7, 2019, at 5:44 p.m., after correcting the cause of the oil intrusion to the generator casing, the main generator was synchronized to the grid. The plant reached 100 percent power on April 11, 2019. On April 27, 2019, the licensee reduced reactor power to 60 percent in order to correct balance of plant steam leaks.
The licensee resumed 100 percent power operations that same day. On May 31, 2019, the licensee commenced power reduction to 13 percent reactor power and removed the main generator from the grid on June 1, 2019. On June 2, 2019, following repairs to the number four turbine stop valve, the licensee synchronized the main generator to the grid at 1:43 a.m. and commenced power ascension. The licensee returned the plant to 100 percent power on June 4, 2019. The reactor remained at approximately 100 percent power for the remainder of the inspection period except for rod sequence exchanges and required testing.
On April 25, 2018, FirstEnergy Solutions (FES) / FirstEnergy Nuclear Operating Company (FENOC) notified the U.S. Nuclear Regulatory Commission (NRC) that they intend to shut down all four of their operating nuclear power plants (ADAMS Accession Number ML18115A007).
Perry Nuclear Power Plant, Unit 1, is scheduled to be shut down May 31, 2021. On March 21, 2018, FES, FirstEnergy Nuclear Generation (FENGEN), and FENOC filed for bankruptcy. The NRC continues to maintain focus on public health and safety and the protection of the environment. This will include a continuous evaluation by inspectors to determine whether the licensee's financial condition is impacting safe operation of the plant.
INSPECTION SCOPES
Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in effect at the beginning of the inspection unless otherwise noted. Currently approved IPs 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 IP requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection Program - Operations Phase. The inspectors performed plant status activities described in IMC 2515 Appendix D, Plant Status and conducted routine reviews using IP 71152, Problem Identification and Resolution. The inspectors 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.

INSPECTION RESULTS
Observation: Flow-Accelerated Corrosion Program 71152 The inspectors reviewed condition reports associated with leaks in system piping induced by flow-accelerated corrosion. The inspectors considered the inputs, evaluations, planned and completed actions for each flow-accelerated corrosion induced leak. The inspectors further reviewed the licensee's programmatic and trend analysis and additionally performed their own search of the corrective action program to validate appropriate inputs were considered during the self-assessment. The inspectors compared the licensee's evaluations, actions, and trend analysis to the programmatic requirements and controls.
The inspectors did not identify any concerns with the licensee's characterization or corrective actions and determined that the scope of each evaluation was appropriate for the circumstances.
EXIT MEETINGS AND DEBRIEFS
The inspectors verified no proprietary information was retained or documented in this report.
- On July 17, 2019, the inspectors presented the integrated inspection results to Mr. F Payne and other members of the licensee staff.
