Change in engineering hour estimate.. Surry Units 1 and 2 -- Acceptance of Requested Licensing Action Re: Amendment (EPID L-2021-LLA-0179)

Gary, I am writing to inform you that the NRC estimate for completion of this LAR will increase from 500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br /> to 570 hours0.0066 days <br />0.158 hours <br />9.424603e-4 weeks <br />2.16885e-4 months <br /> but that the NRC staff still expects to complete this review by September 30, 2022 as requested in the initial LAR letter.

This change was identified during the NRC staffs participation in the audit and was due to the volume of and technical depth associated with the LARs ph calculation and structural information. In addition, the audit will be extended from March 15, 2022 to March 18, 2022, but again, the NRC staff still expects to complete this review on the date stated above per Virginia Electric and Power Companys original request.

Surry Units 1 and 2 -- Acceptance of Requested Licensing Action Re: Amendment (EPID L-2021-LLA-0179)

Gary, By letters dated September 30, 2021 and November 29, 2021 (Agencywide Documents Access and Management System (ADAMS) Accession No.s ML21277A065 and ML21334A169, respectively, Virginia Electric and Power Company (Dominion Energy Virginia) submitted a license amendment for Surry Power Station (Surry) Units 1 and 2.

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. 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. If additional information is needed, you will be advised by separate correspondence. At this time a virtual audit is being considered for this review and additional details will be provided in the near future.

Based on the information provided in your submittal the NRC staff has estimated that this licensing request will take approximately 500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br /> to complete. The NRC staff expects to complete this review by September 30, 2022 as requested in the initial LAR letter. 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, please contact me.
