Dear Jared Smith,
By letter dated August 6, 2025 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML25218A256), Constellation Energy Generation, LLC (CEG) submitted a license amendment request to the Renewed Facility Operating Licenses DPR-19 and DPR-25 for Dresden Nuclear Power Station, Units 2 and 3. Specifically, CEG requests relocation of Technical Specification (TS) 3.3.7.2, Mechanical Vacuum Pump Trip Instrumentation to a licensee-controlled document. 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 whether the application contains sufficient technical information to allow the NRC staff to complete a 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 evaluated the precedence related to this request and determined that, on average, the reviews have required 150 hours0.00174 days <br />0.0417 hours <br />2.480159e-4 weeks <br />5.7075e-5 months <br /> and 8.8 months. To support more efficient process, the NRC is setting a goal of achieving a 15% improvement. Based on that, our estimate for this review is approximately 75 hours8.680556e-4 days <br />0.0208 hours <br />1.240079e-4 weeks <br />2.85375e-5 months <br /> and 5 months. The NRC staff expects to complete the review by January 30, 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 changes, along with updated estimates, will 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, involvement of NRC advisory committees, hearing-related activities, or if the submittal is provided to the NRC in advance of or concurrently with industry program initiatives or pilot applications.
