Report of Facility Changes, Tests, and Experiments and Commitment Changes for Two Year Period Ending April 28, 2022 Waterford Steam Electric Station, Unit 3 NRC Docket No. 50-382 Renewed Facility Operating License No. NPF-38 The summary report of facility changes, tests, and experiments for Waterford Steam Electric Station, Unit 3 (Waterford 3) is provided in Attachment 1 to this letter. This report is submitted in accordance with 10 CFR 50.59(d)(2) and 10 CFR 72.48(d)(2), and covers the period from April 28, 2020 through April 28, 2022. However, no 10 CFR 72.48 evaluations were completed during this reporting period, so no 10 CFR 72.48 report summaries are included in this submittal.
Attachment 2 to this letter provides the summary report of Commitment Changes for the same time period consistent with the guidance in SECY-00-0045 and Nuclear Energy Institute (NEI) 99-04.
There are no new commitments contained in this submittal.
Should you have any questions concerning this issue, please contact John D. Lewis, Manager, Regulatory Assurance, at 504-739-6028.

==SUMMARY==
OF 10 CFR 50.59 AND 10 CFR 72.48 EVALUATIONS 10 CFR 50.59        Initiating                           Summary Evaluation       Document Number 20-01      EC-0000086657-000     Increase frequencies associated with stroke tests of the main turbine governor valves, throttle valves, reheat stop valves, and interceptor valves from 6 months to 12 months, and then to 18 months. The 10 CFR 50.59 Evaluation addressed the potential of extending the turbine valve test interval to decrease turbine valve reliability and increase the turbine missile generation probability.
21-01      EC-0000077544-001     Replace two existing TeloSense Broad
[FCR 90726]        Range Gas Monitors BRGMs) with two ACM 150 Air Composition Monitors and two RAEGuard 2 Photoionization Detectors (PIDs) supplied by Honeywell Analytics, Inc.
The 10 CFR 50.59 Evaluation for Field Change Request (FCR) 90726 demonstrates that the new BRGMs can perform the important to safety function of providing an isolation signal to the Main Control Room Ventilation System in the event of a toxic gas release accident.
21-02      EC-0000088102-000     Updates the bounding Component Cooling Water (CCW) pump runout case in calculation MNQ9-2 to consider a more bounding condition, which is a single failure of a running CCW pump during normal shutdown with a loss of offsite power (LOOP). The 10 CFR 50.59 Evaluation shows that the reduction in the required completion time for time critical action (TCA)-
35 from 2 hours to 50 minutes remains within operator capability and does not adversely affect the ability of the CCW system to perform its required safety functions.
W3F1 -2022-0026 Page 2 of 2 10 CFR 50.59        Initiating                       Summary Evaluation       Document Number 21-03      EC-0000090132-000 Resolves an inconsistency in the seismic boundary location for the Emergency Breathing Air (EBA) piping upstream of the Emergency Breathing Air Tanks. The 10 CFR 50.59 Evaluation shows that the relocation of the EBA seismic boundary at the tank isolation valves (EBA-06A(B)(C)(D))
rather than the upstream check valve (EBA-203) can be implemented without adversely affecting the ability of the EBA system to perform its required safety functions.
22-01      EC-0000091881-000 Temporary modification to replace the Core
[FCR 91960]    Protection Calculator Channel D resistance temperature detector (RTD) RC ITE0112CD1 with that from RC ITE0115-1 for the remainder of Cycle 24. This RTD provides indication of Reactor Coolant System cold leg loop 1B temperature to the Plant Monitoring Computer. The 10 CFR 50.59 Evaluation was limited to the FCR 91960 change to the maximum RTD response time for the reactor protective instrumentation from 8 seconds to 13 seconds.
22-02      EC-0000092099-000 Modified the test interval for the main turbine governor valves, throttle valves, reheat stop valves, and interceptor valves from 6 months to 12 months. The 10 CFR 50.59 Evaluation addressed the potential for a reduction in turbine valve reliability and increased turbine missile generation probability that would result from the lengthened turbine valve test interval.

schedule and made several commitments to achieve this closure and to address Generic Letter (GL) 2004-2. The Pressurizer Water Reactor Owners Group (PWROG) program schedules changed such that Waterford 3 was no longer able to meet that date. Additional revisions were made to commitments due to PWROG schedule changes. Waterford 3 intends to follow resolution strategy proposed by PWROG for establishing in-vessel fiber limits.
On 2/28/2020 PWROG approved implementation guidance to support WCAP-i 17788-P by PWROG members.

The third refueling outage will be RF25 which is scheduled to begin Sep 30, 2023. The A-27552 commitment requires engineering to apply the guidance from the PWROG in order to develop the NRC submittal. The extension date for this action is necessary to allow for this engineering to be completed.
