REGULATORY AUDIT PLAN

BY THE OFFICE OF NUCLEAR REACTOR REGULATION

TO SUPPORT THE REVIEW OF LICENSE AMENDMENT REQUEST

TO REVISE THE WATTS BAR NUCLEAR PLANT UPDATED FINAL SAFETY ANALYSIS

REPORT FOR THE NEW HYDROLOGIC ANALYSIS

TENNESSEE VALLEY AUTHORITY

WATTS BAR NUCLEAR PLANT, UNITS 1 AND 2

DOCKET NOS. 50-390 AND 50- 391

1.0 BACKGROUND

By application dated December 26, 2023 (Agencywide Documents Access and Management System Accession No. ML24003A270), pursuant to Section 50.90 of Title 10 of the Code of Federal Regulations (10 CFR), the Tennessee Valley Authority (TVA) submitted a license amendment request (LAR) to amend Facility Operating License NPF-90 and NPF-96 for Watts Bar Nuclear Plant (Watts Bar), Units 1 and 2, respectively. The proposed amendments would revise the Watts Bar Dual-Unit Updated Final Safety Analysis Report to reflect the results from a new hydrologic analysis.

The Nuclear Regulatory Commission (NRC) staff has determined that a regulatory audit of the supporting information for the LAR should be conducted in accordance with Office of Nuclear Reactor Regulation Office Instruction LIC-111, Regulatory Audits ( ML19226A274).

2.0 REGULATORY AUDIT BASIS

A regulatory audit is a planned license-or regulation-related activity that includes the examination and evaluation of primarily non-docketed information associated with the LAR. An audit is conducted to gain understanding, to verify information, and to identify information that will require docketing to support the basis of a licensing or regulatory decision. An audit will assist the NRC staff in efficiently conducting its review and gaining insights to TVAs processes and procedures. Information identified during the audit that the NRC staff relies upon to make the safety determination must be submitted on the docket.

3.0 REGULATORY AUDIT SCOPE AND METHODOLOGY

NRC staffs objectives of the audit are the following:

  • Confirm the NRC staffs understanding of the LAR.
  • Verify information from a supporting reference used in a calculation that supports the LAR.
  • Identify questions and requests that may become formal requests for additional information (RAIs) per NRR Office Instruction LIC-115, Processing Requests for Additional Information ( ML21141A238).

Additional information needs identified during the audit will be communicated to the designated point of contact.

The NRC will document the final audit items list as an enclosure to the audit report, which will be publicly available.

5.0 TEAM ASSIGNMENTS

The audit team will consist of the following NRC staff:

Team Member Division Area of Responsibility

Kimberly Green NRR/DORL/LPLII -2 Project Manager Kimberly.Green@nrc.gov Ken See NRR/D EX /EXHB Technical Review Kenneth.See@nrc.gov Scott DeNeale Oak Ridge National Technical Review -

denealest@ornl.gov Laboratory contractor Ganesh Ghimire Oak Ridge National Technical Review -

ghimiregr@ornl.gov Laboratory contractor

Key TVA personnel knowledgeable in the areas of interest should be made available for interactions, on a mutually agreeable schedule, to respond to any questions from the NRC staff.

6.0 LOGISTICS

To support the review schedule communicated to TVA when the NRC staff accepted the LAR for technical review, audit activities will be performed remotely and virtually using Microsoft Teams and an internet-based portal made available by TVA.

The internet-based portal should be populated with the documents requested in section 4.0 of this audit plan. The following conditions associated with the portal must be maintained while the NRC staff have access to the portal:

  • The portal will be password-protected. A separate password will be assigned to each member of the NRC staff participating in the audit.
  • The portal should prevent the NRC staff from printing, saving, downloading, or collecting any information directly from the online portal.
  • Conditions of use of the portal will be displayed on the login screen and will require acknowledgment by each user.

Username, password, and other portal access information should be provided directly to members of the NRC audit team. The NRC licensing project manager will provide TVA with names and contact information of the NRC staff participating in the audit (section 5.0 above). All other communications should be coordinated through the NRC project manager.

NRC information requests and communications with TVA staff will be coordinated through the NRCs licensing project manager.

The virtual audit will commence after the internet-based portal is set up and the documentation addressing the item in section 4.0 of this audit plan is made available to the NRC staff. The audit will be conducted during a specified time that is mutually agreeable to the NRC staff and TVA. The NRC project manager will coordinate with the NRC staff and TVA for any teleconferences needed while the NRC staff is reviewing the documentation. T he NRC project manager will inform TVA of the entrance and exit call dates when established. The NRC project manager will inform TVA via routine communications when the NRC staff no longer needs access to the portal.

7.0 DELIVERABLES

The NRC staff will issue an audit summary report within 6 0 days of the audit exit call. The staff may request additional information needed to complete the review of the LAR but will issue any such RAIs separately from audit-related correspondence in accordance with NRR Office Instruction LIC-115, Processing Requests for Additional Information.
