SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring FirstEnergy Nuclear

Operating Companys (FENOCs) performance at Beaver Valley Power Station Units 1 and 2 by conducting the baseline inspections described in this report 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.

PLANT STATUS

Unit 1 began the inspection period shutdown in a planned refueling and maintenance outage (1R25).

1R25 was completed on May 10, 2018, and the unit was returned to 100 percent power

on May 13, 2018. On June 28, 2018, power was reduced to 76 percent to address an emergent condenser tube leak. On June 29, 2018, power was further reduced to 47 percent and remained there for the remainder of the inspection period due to degrading chemistry conditions in the steam generators.

Unit 2 operated at or near rated thermal power for the entire inspection period.

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 FENOCs performance and compliance with Commission rules and regulations, license conditions, site procedures, and standards.

(1) Condition Report 2018-00134, Unit 2 low head safety injection system A surveillance test unable to be completed due to frozen recirculation line

(2) Condition Reports 2017-04061, 2017-07350, Unit 1 chilled water maintenance rule (a)(1)goals and 2017-10581, Unit 1 compressed air maintenance rule (a)(1) goals

OTHER ACTIVITIES

- TEMPORARY INSTRUCTIONS, INFREQUENT, AND ABNORMAL Impact of Financial Conditions on Continued Safe Performance In that the licensee's parent company, FirstEnergy Solutions, was under bankruptcy protection/reorganization during the inspection period, NRC Region I conducted reviews of processes at Beaver Valley. Using the flexibilities in the baseline inspection program, the inspectors evaluated several aspects of FENOCs operations to assess whether any identified plant performance issues could be related to the station's financial condition. The factors reviewed included:

(1) impact on regulatory required plant staffing,

(2) corrective maintenance backlog,

(3) changes to the planned maintenance schedule,

(4) corrective action program implementation, and

(5) reduction in outage scope, including risk-significant modifications. In particular, the inspectors assessed whether FENOC personnel continued to identify problems at an appropriate threshold and enter these problems into the corrective action program for resolution. The inspectors also assessed whether FENOC continued to develop and implement corrective actions commensurate with the safety significance of the problems identified.

INSPECTION RESULTS

Observations 71152 The inspectors noted that the corrective actions for the (a)(1) goals approved for the Unit 1 chilled water system and compressed air system in CR 2017-04061, 2017-07350, and 2017-10581 did not examine the process for determining if the (a)(1) goals were reasonable. As a result, the inspectors reviewed the (a)(1) goals for five systems currently in (a)(1) and three systems recently returned to (a)(2) to determine whether the (a)(1) goals approved in other systems were reasonable. The inspectors noted that four out of the five (a)(1) systems and all three (a)(2) systems had (a)(1) goals that allowed a higher frequency of failure than their respective (a)(2) performance criteria. The four (a)(1) systems were Unit 1 auxiliary feedwater and area ventilation and Unit 2 chilled water and compressed air. The three (a)(2) systems were emergency response facility substation, structures, and Unit 2 heat trace. The inspectors determined that these goals were not reasonable because the systems could be returned to (a)(2) after meeting their (a)(1) goals and their performance may not meet their (a)(2) performance criteria. Although there is a requirement to have goals when a system is in (a)(1), the inspectors found no requirement that specifies criteria for (a)(1) goals. Therefore, the inspectors concluded that there was no performance deficiency. The inspectors also reviewed the performance of the three (a)(2) systems during their (a)(1) monitoring period and determined that their performance justified their return to (a)(2).

EXIT MEETINGS AND DEBRIEFS

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

• On July 26, 2018, the inspectors presented the quarterly resident inspector inspection results to Mr. Richard Bologna, Site Vice President, and other members of the Beaver Valley Power Station staff.
