List of Findings and Violations
No findings or violations of more than minor significance were identified.
Additional Tracking Items
None.
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 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.

INSPECTION RESULTS
Licensee-Identified Non-Cited Violation 71111.21M This violation of very low safety significance was identified by the licensee and has been entered into the licensee corrective action program and is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
Violation: Tile 10 of the Code of Federal Regulations Part 50, Appendix B, Criterion III, Design Control, requires, in part, that design control measures shall provide for verifying or checking the adequacy of design, such as by the performance of design reviews, by the use of adequate or simplified calculational methods, or by the performance of a suitable testing program. Contrary to this requirement, from June 15, 1981 until September 6, 2023, design control measures did not provide for checking the adequacy of design, such as by the performance of design reviews, by the use of adequate or simplified calculational methods, or by the performance of a suitable testing program. Specifically, the design basis operation of RCIC-MOV-MO131, steam supply valve for reactor core isolation cooling turbine, as described in UFSAR Section IV-7.5 was not correctly verified or checked in calculation NEDC 91-079. UFSAR Section IV-7.5 correctly states that RCIC-MOV-MO131 closes on a Level 8 signal. As the RCIC turbine slows, the trip and throttle valve, MO14, closes on low oil pressure. However, NEDC 91-079 incorrectly stated that MO14 closes prior to MO131. As a result, NEDC 91-079 assumed that MO131 is designed to close against 0 psid. The licensee determined that using the system operation described in the UFSAR, MO131 would have to close against 1112 psid. This resulted in a -39% margin for MO131 (in the closed direction).
The licensee analytically regained positive margin by removing conservatism and changing assumptions in calculation NEDC 91-079.
Significance/Severity: Green. The inspectors assessed the significance of the finding using IMC 0609 Appendix A, "The Significance Determination Process (SDP) for Findings At-Power." The inspectors used Exhibit 2 - Mitigating Systems Screening Questions, Item A, and determined that the finding screened to Green since the finding was a deficiency affecting the design or qualification of a mitigating SSC and the SSC maintained its operability or PRA functionality.

EXIT MEETINGS AND DEBRIEFS
The inspectors verified no proprietary information was retained or documented in this report.
