Prairie Island 1 and 2 - Acceptance of Requested Licensing Action re: Request to Revise Technical Specifications to Adopt TSTF-554 (EPID-L-2025-LLA-0142)

Dear Michael Miller,
By letter L-PI-25-026 dated September 3, 2025 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML25247A026), Northern States Power Company, a Minnesota corporation (NSPM, the licensee), doing business as Xcel Energy submitted a license amendment request (LAR) for the Prairie Island Nuclear Generating Plant (PINGP) Units 1 and 2. The proposed amendments requested adoption of Technical Specifications Task Force (TSTF) Traveler, TSTF-554, Revise Reactor Coolant Leakage Requirements, into the PINGP, Units 1 and 2 TS. The TSTF-554 revises the TS definition of Leakage, clarifies the requirements when pressure boundary leakage is detected and adds a Required Action when pressure boundary leakage is identified.
The purpose of this e-mail is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this amendment request. The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the NRC staff to complete its detailed technical review. The acceptance review is also intended to identify any readily apparent deficiencies related to the characterization of the regulatory requirements or plant licensing basis.
Consistent with Section 50.90 of Title 10 of the Code of Federal Regulations (10CFR), an application for an amendment to a license (including the technical specifications) must fully describe the changes requested, and following as far as applicable, the form prescribed for original applications. Section 50.34 of 10CFR addresses the content of technical information required. This section stipulates that the submittal address the design and operating characteristics, unusual or novel design features, and principal safety considerations.
The NRC staff has reviewed your application and concluded that it includes technical information in sufficient detail to enable the NRC staff to complete its detailed technical review and make an independent assessment regarding the acceptability of the proposed amendment in terms of regulatory requirements and the protection of public health and safety and the environment. Given the more limited scope and depth of the acceptance review compared to the detailed technical review, issues that affect the NRC staffs ability to complete the technical review may still be identified despite the acceptance review
being deemed adequate. If additional information is needed, you will be notified by separate correspondence.
The NRC staff has evaluated precedence related to this request. Historically these reviews have required 80 hours9.259259e-4 days <br />0.0222 hours <br />1.322751e-4 weeks <br />3.044e-5 months <br /> and 5.6 months. To support a more efficient process, the NRC is setting a goal of achieving at least 15% improvement (e.g. reduction). Based on that, our estimate for this review is 60 hours6.944444e-4 days <br />0.0167 hours <br />9.920635e-5 weeks <br />2.283e-5 months <br /> and approximately 4 months to complete.
Accordingly, the NRC staff expects to complete this review by January 29, 2026.
If emergent complexities or challenges arise during the NRC staffs review that affect the initial forecasted completion date or result in significant changes to the estimated review hours, the reasons for those changesalong with updated estimateswill be communicated during routine interactions with the assigned project manager. These estimates are based on the NRC staffs initial review of the application and may change due to several factors, including requests for additional information, unanticipated expansion of the review scope, hearing-related activities, or if the submittal is provided to the NRC in advance of or concurrently with industry program initiatives or pilot applications.
