Cooper Nuclear Station - Acceptance Review of LAR to Modify Allowable Value for HPCI Low Flow (EPID L-2024-LLA-0015)

By letter dated February 16, 2024, the Nebraska Public Power District (NPPD) submitted a license amendment request (LAR) (Agencywide Documents Access and Management System (ADAMS) Accession No. ML24047A273) for Cooper Nuclear Station (CNS) to revise the allowable value for CNS Technical Specifications (TS) 3.3.5.1, ECCS Instrumentation, Table 3.3.5.1-1, Emergency Core Cooling System Instrumentation, Function 3.f, High Pressure Coolant Injection Pump Discharge Flow - Low (Bypass), from 490 gallons per minute (gpm) to 523 gpm. This proposed change is due to a planned replacement of the flow-indicating switch with a different model.

The purpose of this email is to provide the results of the Nuclear Regulatory Commission (NRC) staffs acceptance review of this LAR. The acceptance review was performed to determine if there is sufficient information in scope and depth to allow for the NRC staff to complete its detailed technical review of the request. The acceptance review is also intended to identify whether the application has any readily apparent information insufficiencies in its characterization of the regulatory requirements, code, or licensing basis of the plant.

Consistent with Section 50.90 of Title 10 of the Code of Federal Regulations (10 CFR), an amendment to the license (including the TSs) 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 staff to proceed with its detailed technical review and make an independent assessment regarding the acceptability of the proposed amendment request 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 200 hours0.00231 days <br />0.0556 hours <br />3.306878e-4 weeks <br />7.61e-5 months <br /> to complete. The NRC staff expects to complete this review by February 16, 2025. If there are emergent complexities or challenges in our review that would change the initial forecasted completion date or significant changes in the forecasted hours, the reasons for the changes, along with new estimates, will be communicated during our routine interactions.

These estimates are based on the NRC staffs initial review of the application, and they could change due to several factors, including audits, requests for additional information, unanticipated addition to the scope of the review, review by NRC advisory committees, or hearing related activities.

If you have any questions, please contact me.
