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.

Sincerely, John L. Dixon, Jr, Chief Projects Branch D Division of Operating Reactor Safety Docket No. 05000382 License No. NPF-38 Signed by Dixon, John on 01/05/23

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.
