On March 1, 2025, at 0101, the 4A steam MSIV failed to perform its safety function when the valve failed to fully close on a manual demand from the control room. This manual demand was performed in accordance with 4-GOP-103, Power Operation to Hot Standby, as part of the controlled reactor shutdown for a refueling outage. Unit 4 was in Mode 3 at this time, and the 4A MSIV was declared inoperable. The station entered TS 3.7.2 at 0110. After venting the MSIV actuator, slight movement of the valve in the closed direction was noted, and the valve was confirmed shut by the station at 0350.

On March 2, 2025, troubleshooting the 4A MSIV (work orders 40942089 and 40948369)identified the MSIV stroke length was 5.125 inches which did not meet the minimum acceptance criteria of 5.25 inches, again showing that the 4A MSIV failed to fully close. The station attributed the failure to the 125 VDC air exhaust solenoids, which did not vent all the air pressure from the actuator. The exhaust solenoid valves were subsequently replaced, and the 4A MSIV was stroked with satisfactory results under work order 41007344.

The inspectors determined that the exhaust solenoid valves are part of the ESFAS signal required for manual and automatic steam line isolation during main steam line break and steam generator tube rupture events. This resulted in a failure to meet the requirements of TS 3.3.2., specifically Table 3.3.2-1 function 4 for steam line isolation. The TS bases designate that the limiting condition for operation (LCO) requires all instrumentation performing an ESFAS Function, listed in Table 3.3.2-1, in the accompanying LCO, to be operable. The degraded condition of the 4A MSIV actuation exhaust solenoids adversely affected the ability of the actuation system to perform its function in accordance with the licensing and design bases. Updated Final Safety Analysis Report (UFSAR) Section 7.2.1, Protective Systems, describes the licensing basis application of protective ESFAS channels. Specifically, The protective systems are so designed that, once initiated, a protective action goes to completion. The licensee performed a past operability review (POR) under AR 2509225. The licensees review did not assess or declare any portion of the ESFAS system associated with steam line isolation inoperable. The inspectors determined that the licensees POR failed to consider a portion of the ESFAS actuation as a cause of the 4A MSIV to fully close.

Corrective Actions: The 4A MSIV actuator solenoid exhaust valves were replaced and the 4A MSIV was restored to operable on March 6, 2025, after successfully stroking the valve closed within inservice test requirements.

Corrective Action References: AR 2509225

Performance Assessment:

Performance Deficiency: The inspectors determined that the failure to fully consider UFSAR Section 7.2.1 when evaluating the ESFAS steam line isolation signal operability was a performance deficiency, within the licensees ability to foresee and correct. Specifically, the licensee did not consider the impact that the failed steam line isolation ESFAS function would have when manually demanded or during an event such as a main steam line break or steam generator tube rupture during all modes of applicability.

Screening: The inspectors determined the performance deficiency was more than minor because if left uncorrected, it would have the potential to lead to a more significant safety concern. Specifically, a failed ESFAS signal would result in the 4A MSIV not able to perform its safety function to isolate a release during a design basis event (steam generator tube rupture or faulted steam generator) in all required modes of applicability.

Significance: The inspectors assessed the significance of the finding using IMC 0609 Appendix A, The Significance Determination Process (SDP) for Findings At-Power. Since the probabilistic risk assessment (PRA) function was lost for a period greater than the Technical Specification allowed outage time the issue screens to a detailed risk evaluation (DRE). A regional Senior Reactor Analyst (SRA) performed a DRE using SAPHIRE 8 Version 8.2.11 and the Turkey Point Unit 3 & 4 SPAR Model Version 8.81 dated 7/28/2023. The SRA recognized that although the condition likely existed for most of the operating cycle, the condition would only adversely impact the PRA function when there was no differential pressure across the valve. As a result, the condition would only affect a Steam Generator Tube Rupture in Mode 2 or Mode 3 with the main turbine not online. The SRA conservatively assumed that the plant would be in Modes 2 and 3 ten percent of the operating cycle and adjusted the exposure time from 1 year to 36.5 days. The SRA set basic event MSS-ARV-OO-CV32604 to true to model the A MSIV failing open and ran for a steam generator tube rupture event only. The dominant accident sequence was a steam generator tube rupture, a failure to isolate the faulted steam generator, and operators failing to refill to refuel water storage tank and failing to enter the steam generator tube rupture emergency operating procedure. The change in core damage frequency and large early release frequency were both less than 1 E-7 corresponding to a finding of very low safety significance (Green).

Cross-Cutting Aspect: P.2 - Evaluation: The organization thoroughly evaluates issues to ensure that resolutions address causes and extent of conditions commensurate with their safety significance. Specifically, the licensee did not thoroughly evaluate the design basis and licensing basis impacts of the failed 4A MSIV actuator required for ESFAS.

Enforcement:

Severity: The inspectors used the NRC Enforcement Policy to evaluate the traditional enforcement aspects of this issue. The NRC Enforcement Policy example in Section 6.9.d.9 indicates the failure to make a 10 CFR 50.73(a) report was an SL IV NCV.

10 CFR 50.73(a), "Reportable Events," requires, in part, that the licensee shall submit an LER for any event of the type described in this paragraph within 60 days after the discovery of the event.

Contrary to the above, the licensee failed to submit an LER prior to 60 days from March 1, 2025, for an event involving TS noncompliance or condition prohibited by TS described in 10 CFR 50.73(a).

Violation: TS 3.3.2, ESFAS, requires, in part, The ESFAS instrumentation for each Function in Table 3.3.2-1 shall be OPERABLE. Condition 3.3.2.J. requires both steam line isolation manual initiation channel or train operable. The associated TS action statement required, that with one of the following components inoperable the licensee must restore the inoperable channel or train to OPERABLE status within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> or be in MODE 3 within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in MODE 4 within the following 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

Contrary to the above, from October 18, 2023 to March 1, 2025 because of the failure of the solenoid valves associated with the 4A MSIV actuator, the associated ESFAS channel was inoperable and TS 3.5.2.J was not met. The required TS action statement was not entered; the inoperable component was not restored within the required timeframe.

Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.

Failure to Survey at the Frequencies Specified by Procedure Cornerstone Significance Cross-Cutting Aspect Report Section Occupational Radiation Safety Green NCV 05000250,05000251/2025002-02 Open/Closed

[P.1] -

Identification 71124.01 The inspectors identified a Green finding and associated NCV of 10 CFR 20.1501 when the licensee failed to perform several radiation and contamination surveys in the plant on the required frequency.

Description:

NRC inspectors reviewed records associated with the licensee's system of documentation for tracking the completion of routine radiation and contamination surveys within the plant radiologically controlled area (RCA). The frequencies of these surveys are driven by licensee procedure 0-HPA-004, "Scheduling of Periodic Radiation Protection Activities", Revision 4. This procedure requires documentation of daily, weekly, monthly, quarterly, semi-annual, and annual surveys on associated forms within the procedure. Upon reviewing forms that were completed in January and March 2025, the inspectors found that several surveys were not completed on the frequencies specified in the procedure. This included several daily surveys of the hot tool room and hot chemistry lab, one monthly survey of the radwaste building north filling room, one monthly survey of the spent fuel pit heat exchanger room, one monthly survey of the refueling water storage tank, one quarterly survey of the radwaste pipe and valve room, and one quarterly survey of the special nuclear material cage. Upon subsequent scheduled surveys performed in these areas, the licensee did not identify any radiological issues.

Corrective Actions: The licensee placed this issue into their corrective action program (CAP)under AR 2512404. The licensee performed subsequent surveys of all areas missed and did not identify any radiological issues. Additionally, the licensee performed an extent of condition and communicated the issue and expectations to members of the radiation protection (RP)department.

Corrective Action References: AR 2512404

Performance Assessment:

Performance Deficiency: The failure of the licensee to adhere to its procedure for performing radiation and contamination surveys at specified frequencies is a performance deficiency.

Screening: The inspectors determined the performance deficiency was more than minor because if left uncorrected, it would have the potential to lead to a more significant safety concern. Specifically, if surveys are not performed, it could potentially result in the licensee not establishing the appropriate radiological controls.

Significance: The inspectors assessed the significance of the finding using IMC 0609 Appendix C, Occupational Radiation Safety SDP. Specifically, the finding was determined to be of very low safety significance (Green) because it was not related to ALARA planning, did not result in an overexposure beyond regulatory limits, there was no substantial potential for overexposure, and the ability to assess dose was not compromised.

Cross-Cutting Aspect: P.1 - Identification: The organization implements a corrective action program with a low threshold for identifying issues. Individuals identify issues completely, accurately, and in a timely manner in accordance with the program. Specifically, licensee supervision and management missed opportunities to identify and correct the issue before it became repetitive.

Enforcement:

Violation: 10 CFR 20.1501 states, in part, that each licensee shall make or cause to be made, surveys of areas, including the subsurface, that may be necessary for the licensee to comply with the regulations in this part. Turkey Point demonstrates compliance with this regulation via licensee procedure 0-HPA-004, Scheduling of Periodic Radiation Protection Activities, Revision 4. This procedure states that all radiation protection activities are completed in a structured and timely manner by use of the Radiation Protection Daily Schedule/Matrix. This schedule includes but is not limited to daily, weekly, monthly, quarterly, semi-annual and annual surveys. Contrary to the above, for January 2025 and March 2025, the licensee failed to make or cause to be made surveys of areas, including the subsurface, that may be necessary for the licensee to comply with the regulations in this part. Specifically, several routine RP surveys were not completed per the Radiation Protection Schedule/Matrix in accordance with 0-HPA-004.

Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.

Failure to Calibrate Chemistry Count Room Instrumentation at the Frequencies Specified by Procedures Cornerstone Significance Cross-Cutting Aspect Report Section Public Radiation Safety Green NCV 05000250,05000251/2025002-03 Open/Closed

[H.8] -

Procedure Adherence 71124.05 An NRC-identified Green finding and associated NCV of TS 5.4, Procedures, was identified for failure to implement procedures in accordance with the licensees QATR, Section A.7.3. Specifically, the licensee failed to perform annual efficiency checks on gamma spectroscopy equipment as required by procedures.

Description:

NRC inspectors reviewed efficiency confirmation and calibration records for gamma spectroscopy counting instrumentation used to quantify radioactivity in technical specification, effluent, and environmental samples. The inspectors found that, in 2024, annual efficiency confirmations for gamma spectroscopy detectors number 3 and 4 were not performed within the 92-day grace period as required by licensee procedures 0-NCCP-103, Calibration of the Gamma Spectroscopy System, Revision 0, and 0-NCOP-310, Calibration and Operation of the Gamma Spectroscopy Counting System, Revision 7. When efficiency confirmations were performed in January of 2025, the inspectors noted that detectors 3 and 4 were found to be out of tolerance for one of the detection geometries (47mm planchet SS2IP). The licensee subsequently performed full efficiency calibrations, using all geometries, in order to bring both detectors back into operable status.

Corrective Actions: The licensee placed this issue into their CAP under AR 02512394. The licensee developed a work order to perform full calibrations of all the chemistry count room detectors. Additionally, the licensee is planning to update gamma spectroscopy procedures to provide clearer guidance on calibration requirements.

Performance Assessment:

Performance Deficiency: The failure of the licensee to calibrate chemistry count room instrumentation in accordance with licensee procedures was a performance deficiency.

Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Program & Process attribute of the Public Radiation Safety cornerstone and adversely affected the cornerstone objective to ensure adequate protection of public health and safety from exposure to radioactive materials released into the public domain as a result of routine civilian nuclear reactor operation. Specifically, if annual efficiency confirmations are not performed as required, then the gamma spectroscopy equipment may drift out of tolerance and give inaccurate results.

Significance: The inspectors assessed the significance of the finding using IMC 0609 Appendix D, Public Radiation Safety SDP. The inspectors determined the finding to be of very low safety significance (Green) because the resultant dose impact to a member of the public from the failure to calibrate instrumentation used for monitoring effluent streams and the environment would be unlikely to exceed Appendix I to 10 CFR Part 50 and/or 10 CFR 20.1301(e).

Cross-Cutting Aspect: H.8 - Procedure Adherence: Individuals follow processes, procedures, and work instructions.

Enforcement:

Violation: TS 5.4.1 requires, in part, that written procedures be established, implemented, and maintained, as required by the licensees QATR, which includes procedures described in Regulatory Guide (RG) 4.15, Quality Assurance for Radiological Monitoring Programs (Normal Operations) - Effluent Streams and the Environment, Revision 1, dated February 1979. Section C.3 of RG 4.15 recommends procedures for calibration and checks of radiation and radioactivity measurement systems. The licensee implements ITS 5.4.1 requirements in procedures 0-NCCP-103, Calibration of the Gamma Spectroscopy System, Revision 0, and 0-NCOP-310, Calibration and Operation of the Gamma Spectroscopy Counting System, Revision 7. These procedures require an efficiency confirmation or full calibration to be performed on each detector on an annual basis. Contrary to this, in 2024, the licensee failed to perform annual efficiency confirmations or full calibrations on gamma spectroscopy detectors 3 and 4.

Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.

Failure to Maintain Meteorological Monitoring Instruments Cornerstone Significance Cross-Cutting Aspect Report Section Public Radiation Safety Green NCV 05000250,05000251/2025002-04 Open/Closed

[P.3] -

Resolution 71124.07 The inspectors identified a Green finding and associated NCV of TS 5.4., "Procedures," when the licensee failed to minimize extended periods of outage for meteorological monitoring instrumentation. Specifically, in calendar year 2024, meteorological instruments were inoperable on multiple occasions and repairs were not performed in a timely manner, contrary to a licensee procedure which require 90 percent data recovery.

Description:

The inspectors reviewed licensee corrective action documents related to degraded reliability of site meteorological monitoring instruments. In CY 2024, there were 10 ARs written for persistent instrumentation and data integrity issues on the primary and backup meteorological towers. The issues included: temperature and wind direction instruments found out of tolerance during testing, data collection equipment found to be inoperable, both towers being declared inoperable due to bad inputs, and significant instrument deficiencies observed during annual inspections. Guidance for an acceptable meteorological monitoring program is contained in Regulatory Guide 1.23, which states that instruments should be maintained such that the licensee can achieve a 90 percent data recovery rate. The licensee incorporated this guidance into procedure MET-DIR-001, "Land Utilization Department - Lab Administrative Directive Manual: Meteorological System Walkdowns and Inspections". The inspectors noted that data recovery for the measurements of atmospheric stability, wind speed, and wind direction for CY 2024 was approximately 40 percent. The inspectors determined that the licensee's corrective actions failed to ensure their meteorological program complied with providing a minimum of 90 percent data recovery by minimizing extended periods of meteorological instruments outage.

Corrective Actions: The licensee continues to work on a bridging strategy to acquire equipment to repair the towers (AR 02515365).

Corrective Action References: ARs 02510800 and 02515365

Performance Assessment:

Performance Deficiency: The licensee's failure to maintain meteorological instruments such that they achieved a 90 percent data recovery rate, as required by a licensee procedure, was a performance deficiency.

Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Plant Facilities/Equipment and Instrumentation attribute of the Public Radiation Safety cornerstone and adversely affected the cornerstone objective to ensure adequate protection of public health and safety from exposure to radioactive materials released into the public domain as a result of routine civilian nuclear reactor operation.

Failure to minimize extended periods of outage for meteorological monitoring instruments increases the likelihood that they will be unavailable if called upon during an accident.

Significance: The inspectors assessed the significance of the finding using IMC 0609 Appendix D, Public Radiation Safety SDP. The inspectors used the Radioactive Environmental Monitoring Program portion to assess the significance of the violation. All findings associated with this branch are given a green significance.

Cross-Cutting Aspect: P.3 - Resolution: The organization takes effective corrective actions to address issues in a timely manner commensurate with their safety significance. Corrective actions for meteorological tower instrument problems were not timely or effective in CY 2024.

Enforcement:

Violation: TS 5.4.1 requires, in part, that the licensee establish, implement, and maintain written procedures required by the QATR. Appendix B to the QATR, requires, in part, that the licensee use Appendix A to Regulatory Guidance 1.33 for establishing the types of procedures that are necessary to control and support plant operation. Appendix A to Regulatory Guide 1.33 requires in part, procedures for meteorological monitoring. Procedure MET-DIR-001, Land utilization department - lab administrative directive manual:

meteorological system walkdowns and inspections, requires, in part, that the licensee maintains a meteorological program providing at a minimum a 90 percent data recovery and minimize extended periods of meteorological instruments outage.

Contrary to the above, for calendar year 2024, the licensee failed to minimize extended periods of outage and ensure that meteorological instruments maintained a 90 percent or above data recovery rate.

Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.

Unresolved Item (Closed)

Failure to Classify a Locked High Radiation Area Event as a Performance Indicator Non-Conformance URI 05000251/2024004-02 71151

Description:

The NRC identified a minor violation of 10 CFR 50.9, Completeness and Accuracy of Information, for failing to provide complete and accurate performance indicator (PI) data associated with a non-conformance with TS 6.12, High Radiation Areas, that resulted in the loss of radiological control over work activities in the respective area. Performance indicator data is material to the NRC because it is relied upon to assess the performance of power reactor licensees. The NRC issued a self-revealed Green finding and associated NCV for this event in NRC Inspection Report 2023004 (ADAMS Accession Number ML24043A263). The licensee subsequently submitted Frequently Asked Question (FAQ) 25-01 - Reporting PI for Dose Rate Alarm requesting interpretation of whether this event should have been counted against the Occupational Safety Effectiveness Performance Indicator (OR01). The NRC responded (draft response under ADAMS Accession Number ML25150A283) indicating that this event should have been reported as an occurrence against PI OR01 starting in the last quarter of 2023 and should have remained as a reportable occurrence for the three subsequent quarters.

This violation of 10 CFR 50.9 is minor because it is less significant than the Severity Level IV examples in Section 6.9 of the Enforcement Policy. Specifically, if the inaccurate or incomplete PI data had been submitted accurately during its active reporting period, it would not have resulted in the PI crossing the Green/White threshold or in an increase in NRC inspection oversight. Since, at the time of submitting the FAQ, the reporting period for this occurrence had already expired, the licensee is not required to amend the previously submitted PI data.

Corrective Action Reference(s): Inspection Reports 2023004 (ADAMS Accession Number ML24043A263) and 2024004 (ADAMS Accession Number ML25031A060).
