Monticello - Acceptance of LAR to Revise TS to Adopt TSTF-566 and TSTF-580, Revision 1 (EPID L-2024-LLA-0154)
Hi Mike and Rick, By "L-MT-24-026, Application to Revise Technical Specifications to Adopt TSTF-566, Revise Actions for Inoperable RHR [[system" contains a listed "[" character as part of the property label and has therefore been classified as invalid. Subsystems, and TSTF-580, Revision 1, Provide Exception from Entering Mode 4 with No Operable RHR Shutdown Cooling, Usin|letter dated October 21, 2024]], (Agencywide Documents Access and Management System (ADAMS)
Accession No. ML24327A157), Northern States Power Company, a Minnesota Corporation doing business as Xcel Energy, (NSPM, the licensee), submitted a license amendment request (LAR) for the Monticello Nuclear Generating Plant. The proposed amendment would revise the technical specification (TS) actions applicable when a residual heat removal (RHR) shutdown cooling subsystem is inoperable and provides a TS exception to entering Mode 4 if both required RHR shutdown cooling subsystems are inoperable. The requested changes are in accordance with Technical Specification Task Force (TSTF) Traveler TSTF-566, Revise Actions for Inoperable RHR Shutdown Cooling Subsystems, and TSTF-580, Revision 1, Provide Exception from Entering Mode 4 with No Operable RHR Shutdown Cooling, which are part of the Consolidated Line Item Improvement Process.
The purpose of this email 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 whether the application has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant.
Consistent with Section 50.90 of Title 10 of the Code of Federal Regulations (10 CFR), 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 10 CFR 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 does provide 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 lesser scope and depth of the acceptance review as compared to the detailed technical review, there may be instances in which issues that impact the NRC staffs ability to complete the detailed technical review are identified despite completion of an adequate acceptance review. You will be advised of any further information needed to support the NRC staffs detailed technical review by separate correspondence.
Based on the information provided in your submittal, the NRC staff has estimated that this licensing request will take approximately 105 hours0.00122 days <br />0.0292 hours <br />1.736111e-4 weeks <br />3.99525e-5 months <br /> to complete. The NRC staff expects to complete this review in approximately 6 months, which is June 12, 2025. If there are emergent complexities or challenges in our review that would cause changes to the initial forecasted completion date or significant changes in the forecasted hours, the reasons for the changes, along with the new estimates, will be communicated during the routine interactions with the assigned project manager.
These estimates are based on the NRC staffs initial review of the application, and they could change, due to several factors including requests for additional information, unanticipated addition of scope to the review, and
2 review by NRC advisory committees or hearing-related activities. Additional delay may occur if the submittal is provided to the NRC in advance or in parallel with industry program initiatives or pilot applications.
