1.0 PROPOSED CHANGE

S By application dated March 12, 2025 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML25071A416), as supplemented by letter dated April 15, 2025 (ML25105A222), Northern States Power Company, a Minnesota Corporation (NSPM, the licensee), requested changes to the Technical Specifications (TSs) for Prairie Island Nuclear Generating Plant (Prairie Island, PINGP), Units 1 and 2. The license amendment request (LAR, application) is based on Technical Specifications Task Force (TSTF) Traveler TSTF-541, Revision 2, Add Exceptions to Surveillance Requirements for Valves and Dampers Locked in the Actuated Position (TSTF-541) (ML19240A315), and the associated U.S. Nuclear Regulatory Commission (NRC, the Commission) staff safety evaluation (SE) of TSTF-541 (ML19323E926).

Limiting Conditions for Operation (LCOs) in the TS identify the lowest functional capability or performance level of equipment required for safe operation of the facility. Surveillance requirements (SRs) are requirements relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the LCOs will be met. Several existing SRs require the licensee to verify that each train of specified trains actuates on an actual or simulated actuation signal. When the trains actuate, valves and dampers within the trains will, if needed, reposition to their actuated position, which is the position appropriate to respond to the transient or accident that caused the actuation. The proposed amendment would eliminate the need to verify that a damper or valve has repositioned if the damper or valve is secured in its actuated position by adding a phrase to each SR as described in Section 1.2 of this SE.

The proposed amendment is based on TSTF Traveler TSTF-541, Revision 2, Add Exceptions to Surveillance Requirements for Valves and Dampers Locked in the Actuated Position (TSTF-541) (ML19240A315), and the associated NRC staff SE of TSTF-541 (ML19323E926). Section 1.1 of the NRC staffs SE of TSTF-541 discusses the reason for the proposed changes.

1.1 System Descriptions The control room special ventilation system (CRSVS) provides a protected environment from which occupants can control the unit following an uncontrolled release of radioactivity, hazardous chemicals, or smoke. The purpose of SR 3.7.10.3 is to verify that each train/subsystem starts and operates on an actual or simulated actuation signal.

The shield building ventilation system (SBSVS) is required to ensure that radioactive materials that leak from the primary containment into the shield building (secondary containment) following a design-basis accident are filtered and adsorbed prior to exhausting to the environment. The containment has a secondary containment called the shield building, which is a concrete structure that surrounds the steel primary containment vessel. Between the containment vessel and the shield building inner wall is an annular space that collects any containment leakage that may occur following a loss-of-coolant accident (LOCA). The SBSVS establishes a negative pressure in the annulus between the shield building and the steel containment vessel. Filters in the system control the release of radioactive contaminants to the environment. The SBSVS consists of two separate and redundant trains. Each train includes a heater, cooling coils, a prefilter, moisture separators, a high-efficiency particulate air (HEPA) filter, an activated charcoal adsorber section for removal of radioiodines, and a fan. Ductwork, valves and/or dampers, and instrumentation also form part of the system. The system initiates and maintains negative air pressure in the shield building by means of filtered exhaust ventilation of the shield building following receipt of a safety injection signal. The purpose of SR 3.6.9.3 is to verify proper actuation of all train components, including dampers, on an actual or simulated actuation signal. The purpose of SR 3.6.9.4 is to verify proper actuation of isolation dampers on an actual or simulated actuation signal.

The auxiliary building special ventilation system (ABSVS), in conjunction with other normally operating systems, also provides environmental control of temperature and humidity in the emergency core cooling system (ECCS) pump room area and the lower reaches of the auxiliary building. Ductwork, valves or dampers, and instrumentation also form part of the system, as well as demisters functioning to reduce the relative humidity of the air stream. During emergency operations, the ABSVS dampers are realigned, and fans are started to begin filtration. Upon receipt of the actuating ECCS signal(s), normal air discharges from the ECCS pump room are isolated, and the stream of ventilation air is discharged through the system filter trains. The prefilters or demisters remove any large particles in the air, and any entrained water droplets present, to prevent excessive loading of the HEPA filters and charcoal adsorbers. The purpose of SR 3.7.12.4 is to verify proper actuation of all train components, including dampers, on an actual or simulated actuation signal.

1.2 Description of Proposed Changes to Adopt TSTF 541 In accordance with NRC staff-approved TSTF-541, the licensee proposed to revise certain SRs by adding exceptions to the SRs for automatic valves or dampers that are locked, sealed or otherwise secured in the actuated position. The proposed revisions, therefore, allow the licensee to meet the LCOs without having to test for actuation those valves or dampers that are already secured in the actuated position. Specifically, the licensee proposed the following changes to adopt TSTF-541. The proposed new text is shown in italics.

SR 3.6.9.3 Verify each SBVS train actuates on an actual or simulated actuation signal, except for dampers and valves that are locked, sealed, or otherwise secured in the actuated position.

SR 3.6.9.4 Verify each SBVS isolation dampers actuate on an actual or simulated signal, except for dampers that are locked, sealed, or otherwise secured in the open position.

SR 3.7.10.3 Verify each CRSVS train actuates on an actual or simulated actuation signal, except for dampers and valves that are locked, sealed, or otherwise secured in the actuated position.

SR 3.7.12.4 Verify each ABSVS train actuates on an actual or simulated actuation signal, except for dampers and valves that are locked, sealed, or otherwise secured in the actuated position.

1.3 Additional Proposed TS Changes In addition to the changes proposed consistent with the traveler discussed in Section 1.1, the licensee proposed the following variations.

1.3.1 Editorial Variations The licensee noted that PINPG, Units 1 and 2, TSs have different numbering and nomenclature than standard technical specifications (STSs).

2.0 REGULATORY EVALUATION

The regulation under 10 CFR 50.36(b) requires that:

Each license authorizing operation of a utilization facility will include technical specifications. The technical specifications will be derived from the analyses and evaluation included in the safety analysis report, and amendments thereto, submitted pursuant to [10 CFR] 50.34 [Contents of applications; technical information.] The Commission may include such additional technical specifications as the Commission finds appropriate.

Additionally, under 10 CFR 50.92(a), in determining whether an amendment to a license will be issued to the applicant, the Commission will be guided by the considerations which govern the issuance of initial licenses to the extent applicable and appropriate. The considerations for issuance of operating licenses in 10 CFR 50.57(a)(3) provide that there must be reasonable assurance that the activities at issue will not endanger the health and safety of the public. The LAR asks for changes to SRs, which are controlled by 10 CFR 50.36(c)(3) (saying that SRs are requirements relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the LCOs will be met). Accordingly, the amended SRs that no longer require verification of valves and dampers already in, and secured in, their actuated positions, must continue to provide reasonable assurance that the LCOs will be met and the other standards of 10 CFR 50.36(c)(3) will be met.

The NRC staffs guidance for the review of TSs is in Chapter 16.0, Technical Specifications, of NUREG-0800, Revision 3, Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR [Light-Water Reactor] Edition (SRP), March 2010 (ML100351425).

As described therein, as part of the regulatory standardization effort, the NRC staff has prepared STSs for each of the LWR nuclear designs. Accordingly, the NRC staffs review includes consideration of whether the proposed changes are consistent with the NUREG-1431, Revision 5, Standard Technical Specifications, Westinghouse Plants (ML21259A155), as modified by NRC-approved travelers.

3.0 TECHNICAL EVALUATION

3.1 Proposed TS Changes to Adopt TSTF-541 The NRC staff compared the licensees proposed TS changes in Section 1.2 of this SE against the changes approved in TSTF-541. In accordance with the SRP Chapter 16.0, the NRC staff determined that the STS changes approved in TSTF-541 are applicable to PINGP, Units 1 and 2, TSs because PINGP, Units 1 and 2, are Westinghouse Pressurized Water Reactor (PWR) designs and the NRC staff approved the TSTF-541 changes for Westinghouse PWR designs.

Therefore, the NRC staff concludes that the licensees proposed changes to the PINGP, Units 1 and 2, TSs in Section 1.2 of this SE are consistent with TSTF-541.

As defined in TS [1.1], a system, subsystem, train, component, or device shall be operable:

when it is capable of performing its specified safety function(s) and when all necessary attendant instrumentation, controls, normal or emergency electrical power, cooling and seal water, lubrication, and other auxiliary equipment that are required for the system, subsystem, train, component, or device to perform its specified safety function(s) are also capable of performing their related support function(s).

The SRs, as proposed to be amended, would exclude the need to verify actuation of dampers and valves that do not, in fact, actuate (e.g., change position) in response to an actuation signal.

The licensees LAR contains the following statements:

While the proposed exceptions permit automatic valves and dampers that are locked, sealed, or otherwise secured in the actuated position to be excluded from the SR in order to consider the SR met, the proposed changes will not permit a system that is made inoperable by locking, sealing, or otherwise securing an automatic damper in the actuated position to be considered operable. As stated in the SR 3.0.1 Bases:

"Nothing in this Specification, however, is to be construed as implying that systems or components are OPERABLE when:

a. The systems or components are known to be inoperable, although still meeting the SRs."

NSPM acknowledges that under the proposed change, the affected valves and dampers may be excluded from the SR when locked, sealed or otherwise secured in the actuated position. However, if the safety analysis assumes movement from the actuated position following an event, or the system is rendered inoperable by locking, sealing, or otherwise securing the valve or damper in the actuated position, then the system cannot perform its specified safety function and is inoperable regardless of whether the SR is met.

NSPM acknowledges for components for which the SR allowance can be utilized, the SR must be verified to have been met within its required Frequency after removing the valve or damper from the locked, sealed or otherwise secured status. If the SR exception is utilized to not test the actuation of a valve or damper and the specified Frequency of the SR is exceeded without testing the component, the SR must be performed on the component when it is returned to service in order to meet the SR.

The licensee provided a verification statement in Section 2.3 to confirm that existing administrative processes will be used to assess the operability of the system or any supported systems when utilizing the SR allowances.

Given the above statements provided on the docket to adopt TSTF-541, the NRC staff determined that there is reasonable assurance that the licensee will continue to properly control affected equipment in accordance with existing regulations and requirements when using the exceptions added to the respective SRs.

The amended SRs will continue to require the licensee to verify that valves and dampers that must actuate perform their safety functions and support functions by being able to change position. But the NRC staff finds that it is not necessary to verify actuation of valves and dampers that are already in their actuated positions, and are locked, sealed, or otherwise secured in those positions Therefore, the NRC staff determined that the amended PINGP, Units 1 and 2, TSs will continue to meet 10 CFR 50.36(c)(3) because the revised SRs will continue to provide reasonable assurance that necessary quality of systems and components is maintained and that the LCOs will be met.

Thus, the proposed changes continue to meet the requirements of 10 CFR 50.36(c)(3) as discussed in Section 3.0 of the NRC staffs SE of TSTF-541.

3.2 Additional Proposed TS Changes 3.2.1 Editorial The licensee noted that PINGP, Units 1 and 2, TSs have different numbering and nomenclature than STS. The NRC staff finds that the different TS numbering and nomenclature changes are acceptable because they do not substantively alter TS requirements.

3.3 TS Change Consistency The NRC staff reviewed the proposed TS changes for technical clarity and consistency with the existing requirements for customary terminology and formatting. The NRC staff finds that the proposed changes are consistent with Chapter 16.0 of the SRP and are therefore acceptable.

4.0 STATE CONSULTATION

In accordance with the Commissions regulations, the Minnesota State officials were notified of the proposed issuance of the amendments on June 10, 2025. The State officials had no comments.

5.0 ENVIORNMENTAL CONSIDERATION The amendments change a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20. The NRC staff has determined that the amendments involve no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendments involve no significant hazards consideration, published in the Federal Register on June 10, 2025 (90 FR 2440), and there has been no public comment on such finding. Accordingly, the amendments meet the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendments.

6.0 CONCLUSION

The Commission has concluded, based on the considerations discussed above, that: 1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) there is reasonable assurance that such activities will be conducted in compliance with the Commissions regulations, and (3) the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public.
