SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees
performance by conducting a Quarterly inspection at Farley Units 2 and 1 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. Findings and
violations being considered in the NRCs assessment are summarized in the table below.
List of Findings and Violations
No findings were identified.
Additional Tracking Items
None.
PLANT STATUS
Unit 1 began the report period at or near 100 percent rated thermal power (RTP). On February
19, the Unit 1 reactor was shut down to mode 3 to troubleshoot and repair issues with the main
generator hydrogen cooler. Following this work, Unit 1 was returned to mode 1 on February 25
and achieved 100 percent RTP on March 6. Unit 1 stayed at or near 100 percent RTP for the
remainder of the report period.
Unit 2 began the report period at approximately 100 percent RTP and maintained that power
level for the entire report 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 licensee performance and compliance
with Commission rules and regulations, license conditions, site procedures, and standards.
