SUBJECT:

H. B. ROBINSON STEAM ELECTRIC PLANT, UNIT 2 - ACCEPTANCE OF REQUESTED LICENSING ACTION RE: CORRECTION TO NON-CONSERVATIVE TECHNICAL SPECIFICATIONS FIGURE 3.4.3-2, PRESSURE/TEMPERATURE LIMIT COOLDOWN CURVES (EPID L-2021-LLA-0223)

By letter dated December 9, 2021, (Agencywide Documents Access and Management System (ADAMS) Accession No. ML21343A087), Duke Energy Progress, LLC (Duke Energy, the licensee) submitted a license amendment request for H.B. Robinson Steam Electric Plant, Unit No. 2 (Robinson). The proposed amendment would correct a non-conservative Technical Specification (TS) related to TS 3.4.3, RCS Pressure and Temperature (P/T) Limits. Specifically, a portion of TS Figure 3.4.3-2 (P/T limit cooldown curves) is being corrected because it does not reflect the data approved in Amendment No.

248 (ADAMS Accession No. ML16285A404).

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 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) [or construction permit] 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, the NRC staff has estimated that this licensing request will take approximately 180 hours0.00208 days <br />0.05 hours <br />2.97619e-4 weeks <br />6.849e-5 months <br /> to complete. The NRC staff expects to complete this review in approximately 12 months, which is January 2022. 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 review by NRC advisory committees or hearing-related activities.

If you have any questions regarding this matter, I may be reached at 301-415-1387 or by e-mail.
