INSPECTION RESULTS

URI Containment Air Recirculation System Design Function 71111.17T (Discussed) Change URI 05000266,05000301/2021010-01

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.
