This revision includes changes to reflect TVA organization changes that became effective on January 28, 2025.
Criterion I, Organization, of Appendix B, Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants, to Title 10 of the Code of Federal Regulations (10 CFR)
Part 50, Domestic Licensing of Production and Utilization Facilities, requires, in part:
The applicant shall be responsible for the establishment and execution of the quality assurance programThe authority and duties of person and organizations performing activities affecting the safety-related functions of structures, systems, and components shall be clearly established and delineated in writingThe persons and organizations performing quality assurance functions shall have sufficient authority and organizational freedom to identify quality problems; to initiate, recommend, or provide solutions; and to verify implementation of solutions. The persons organizations performing quality assurance functions shall report to a management level so that the required authority and organizational freedom, including sufficient independence from cost and schedule when opposed to safety considerations, are provided.
Issue In Part II, Section 1, subsection 1.5.C, TVA describes the role and responsibilities of the General Manager, Quality Assurance. The QAPD states, in part (emphasis added by underlined text):
The General Manager, Quality Assurance (QA) is responsible for the performance of the quality assurance oversight organization for the nuclear operating fleet, vendor support, CRN ESP, and the TVA New Nuclear Program.
The General Manager, QA has an independent reporting relationship with the CNO on quality issues.
However, in subsection 1.3, it states (emphasis added by underlined text):
The Executive Vice President/Chief Operating Officer (COO) is responsible for TVAs transmission and power supply, power operations, generation projects and fleet services. The COO is also responsible for the TVA New Nuclear Program and Projects through the Senior Vice President, New Nuclear Projects.
A.
Senior Vice President, New Nuclear Projects The Senior Vice President, New Nuclear Projects is responsible for new nuclear site projects and program technical and administrative activities.
The Senior Vice President, New Nuclear Projects is also responsible to ensure quality requirements are met for activities performed by the site project and program and their contractors. The management position CNL-25-075 E1-2 of 3 responsible for the New Nuclear Program reports to the Senior Vice President, New Nuclear Projects.
In addition, subsection 1.5.B, TVA states that the Senior Vice President, Engineering and Operations Support, is also responsible for governance, oversight, and support of TVA New Nuclear Program and Projects activities.
It is not clear to the NRC staff whether the General Manager, QA has oversight of New Nuclear Projects since this position only states it has oversight of TVA New Nuclear Program and CRN ESP. In addition, given that the General Manager, QA reports to the CNO on quality issues and the CRN ESP are the responsibility of the COO, it is not clear to the NRC staff that the General Manager, QA has sufficient authority to provide oversight of CRN ESP and New Nuclear Programs as required by Criterion I of Appendix B to 10 CFR Part 50.
Request The NRC staff requests that TVA:
(1) identify in the TVA Fleet QAPD the position that has oversight of TVA New Nuclear Projects (other the CRN ESP).
(2) clarify how the General Manager, QA reports to a management level such that the General Manager, QA has the required authority and organizational freedom to perform oversight functions of the CRN ESP and New Nuclear Programs.
TVA Response to RAI 1 The General Manager, Quality Assurance has oversight of Tennessee Valley Authority (TVA)
New Nuclear Projects. TVAs only new nuclear project is the Clinch River Nuclear (CRN)
Small Modular Reactor (SMR) Project.
TVA Fleet QAPD has been revised for clarity. The revised portion of Part II, Section 1, Subsection 1.4.C is included below.
The General Manager, Quality Assurance (QA) is responsible for the performance of the quality assurance oversight function for the nuclear operating fleet, vendor support, and the TVA New Nuclear Program and Projects. The General Manager, QA has an independent reporting relationship with the CNO on quality issues.
The General Manager, QA administers quality assurance responsibilities through the management positions responsible for Corporate QA, Site QA, and QA Services.
CNL-25-075 E1-3 of 3 TVA Response to RAI 2 The TVA Fleet QAPD Executive Summary states in part, This Fleet QAPD applies to the Clinch River Nuclear (CRN) Small Modular Reactor (SMR) Project while under an approved early site permit (ESP) as well as the TVA New Nuclear Program Organization This is further stated in detail under Part I, Section 2, Scope/Applicability.
The required authority of the General Manager, QA to perform oversight functions of the CRN ESP and New Nuclear Program is established in Part II, Section 1, Subsection 1.4 for the Executive Vice President/Chief Nuclear Officer (CNO) which states in part, The CNO also has the overall responsibility for the establishment, implementation, and administration of the TVA Nuclear Fleet QAPD and the evaluation of its effectiveness. This responsibility is implemented through the General Manager, QA.
The organizational freedom of the General Manager, QA to perform oversight functions of the CRN ESP and New Nuclear Program is established in the independent reporting relationship with the CNO on quality issues described in Part II, Section 1, Subsection 1.4.C.
Part II, Section 1, Subsections 1.2 and 1.2.A for the President/CEO and Senior Vice President, New Nuclear Projects, respectively have been revised to provide clarity in how the General Manager, QA reports to a management level such that the General Manager, QA has the required authority and organizational freedom to perform oversight functions of the CRN ESP and New Nuclear Program.

Quality Assurance Program Description for TVA Nuclear Quality Assurance Plan (NQAP)
TVA-NQA-PLN89-A, Revision 44, April 2025 10 PART I INTRODUCTION SECTION 1 GENERAL The QAPD is the top-level policy document that establishes the Quality Assurance policy and assigns major functional responsibilities for all quality related activities conducted by or for TVA Nuclear. The QAPD describes the methods and establishes Quality Assurance (QA) and administrative control requirements that meet 10 CFR 50, Appendix B and 10 CFR 72, Subpart G. The QAPD is based on the requirements and guidance of ASME NQA-1-2015, Quality Assurance Requirements for Nuclear Facility Applications, Parts I and II, with specific reference to selected Part III and Part IV sections, as identified in this document.
The QAP is defined by the NRC-approved regulatory document that describes the QA elements (i.e., the QAPD), along with the associated implementing documents.
Policies establish high-level responsibilities and authority for carrying out important administrative functions which are outside the scope of the QAPD.
Procedures and instructions that control quality related activities will be developed and implemented prior to commencement of those activities.
x Procedures may establish practices for certain activities which are common to all TVA Nuclear organizations performing those activities, so that the activity is controlled and carried out in a manner that meets QAPD requirements.
x Procedures specific to a site, organization, or group establish detailed implementation requirements and methods and may be used to implement policies or be unique to particular functions or work activities.
SECTION 2 SCOPE/APPLICABILITY The QAPD applies to (1) TVA Nuclear personnel and organizations performing activities that could affect quality related structures, systems, and components (SSCs) at TVA's nuclear plants and Independent Spent Fuel Storage Installations (ISFSIs); (2) TVA non-nuclear organizations working either directly under the TVA QAPD, under their program as required by intergroup agreement, or under the quality requirements specified in applicable procurement documents; (3) contractor activities that could affect quality related SSCs, unless TVA Nuclear has approved alternate administrative controls for those activities; and (4) quality related activities which addresses infrastructure and programmatic matters with siting, design, licensing, and planning for TVAs New Nuclear Projects and New Nuclear Program until such time as the Quality Assurance Program Description for TVA New Nuclear (NNQAP, Reference NNP-TR-001-NP-A) is implemented and the Construction Permit Application (CPA) for CRN Project is approved by the NRC. After this milestone, New Nuclear Program and Projects work for siting, site-selection, design, licensing, planning, construction, and operation of new TVA nuclear plants (including the CRN SMR Project after issuance of the Construction Permit) are addressed under the TVA NNQAP.
