Watts Bar Units 1 and 2 - Acceptance for Review - Application to Revise Technical Specifications Regarding DC Electrical Systems Consistent With TSTF-500, Revision 2 (L-2018-LLA-0494)

Russ, By letter dated November 29, 2018 (Agencywide Documents Access and Management System (ADAMS)

Accession No. ML18334A389), the Tennessee Valley Authority (TVA, the licensee) submitted a license amendment request (LAR) to Facility Operating License Nos. NPF-90 and NPF-96 for Watts Bar Nuclear Plant (WBN), Units 1 and 2, respectively. The proposed amendments would modify technical specification requirements related to direct current electrical systems in accordance with Technical Specification Task Force (TSTF) Traveler TSTF-500, Revision 2, DC Electrical Rewrite - Update to TSTF-360.

The purpose of this letter 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 10 CFR 50.90, an amendment to the 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 TVAs 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. TVA 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 TVAs submittal, the NRC staff has estimated that this licensing request will take approximately 250 hours10.417 days <br />1.488 weeks <br />0.342 months <br /> to complete. The NRC staff expects to complete this review in approximately 11 months, which is November 2019, as requested in TVAs application. 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 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, and unanticipated addition of scope to the review.

Additional delay may occur if the submittal is provided to the NRC in advance or in parallel with industry program initiatives or pilot applications.
