SUBJECT:
WATERFORD STEAM ELECTRIC STATION, UNIT 3 - REVISED INTEGRATED INSPECTION REPORT 05000382/2022003
Dear John Ferrick:
On September 30, 2022, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at Waterford Steam Electric Station, Unit 3. The results of this inspection were originally issued in a report, dated November 1, 2022 (Agencywide Document Access and Management Systems (ADAMS) Accession No. ML22300A103).
The NRC staff subsequently determined that two inspections were recorded in the incorrect subsection of the inspection procedure. This error was due to an administrative oversight; the appropriate inspection was completed in accordance with the respective inspection procedure.
The 71111.01 inspection sample completed on August 31, 2022, was inspecting external flooding, not seasonal extreme weather. The 71114.06 inspection sample completed on September 13, 2022, was inspecting a full site drill, not a limited-scope training exercise for licensed operators. Both inspection samples are now in the correct subsection.
This letter, its enclosure, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with Title 10 of the Code of Federal Regulations 2.390, Public Inspections, Exemptions, Requests for Withholding.

SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at Waterford Steam Electric Station, Unit 3, 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.
List of Findings and Violations
No findings or violations of more than minor significance were identified.
Additional Tracking Items
None.
PLANT STATUS
Unit 3 began the inspection period at rated thermal power and remained at or near rated thermal power for 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. 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 activities described in IMC 2515, Appendix D, Plant Status, observed risk significant activities, and completed on-site portions of IPs. 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.
