Unit 2 began the inspection period at rated thermal power and remained at or near full power throughout the remainder of the 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.

INSPECTION RESULTS
URI (Discussed)
Containment Air Recirculation System Design Function Change URI 05000266,05000301/2021010-01 71111.17T
Description:
The licensee reassessed 10 CFR 50.59 Screening 2018-0157, Provide Additional Containment Cooling Using 1/2SW-2907 or 1/2SW-2908, HX-15A-D Cont Recirc HX Emergency FCV, dated August 27, 2018, which evaluated a change to an operating procedure for the containment air recirculation system associated with the alignment of the containment air recirculation system to provide additional containment cooling during normal operations.
The licensees reassessment concluded that the change was adverse and the licensee performed a 10 CFR 50.59 evaluation, which was documented in Evaluation 2021-001, OI 72, Containment Air Recirculation System.
The inspectors began reviewing the 10 CFR 50.59 evaluation and updated screening; however, the inspection was not complete at the end of the inspection period and will continue into the second quarter. This URI remains open.
EXIT MEETINGS AND DEBRIEFS
The inspectors verified no proprietary information was retained or documented in this report.
On April 12, 2022, the inspectors presented the integrated inspection results to Mr. M. Strope, Site Vice President, and other members of the licensee staff.
