UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 Mr. Joseph W. Shea Vice President, Nuclear Licensing Tennessee Valley Authority 1101 Market Street, LP 3D-C Chattanooga, TN 37402-2801 August4,2014

SUBJECT:

WATIS BAR NUCLEAR PLANT, UNIT 2-PLAN FOR THE ONSITE AUDIT REGARDING TENNESSEE VALLEY AUTHORITY'S LICENSING PRESERVATION PROGRAM

Dear Mr. Shea:

As part of the Watts Bar Nuclear Plant (WBN), Unit 2 operating licensing review reactivation, and consistent with the Commission's staff requirements dated July 25, 2007 (Agencywide Documents Accession Management System (ADAMS) Accession No. ML072060688; SECY-07-0096),

the U.S. Nuclear Regulatory Commission (NRC) staff required the Tennessee Valley Authority (TVA) to develop and implement a licensing basis preservation program to confirm the validity of previously completed NRC safety evaluations to the final WBN Unit 2 design, or to identify topics that require supplemental review. In Supplement 22 of NUREG-0847, "Safety Evaluation Report Related to the Operation of Watts Bar Nuclear Plant (WBN), Unit 2," the NRC staff documented the results of their review of TVA's Program for Maintenance and Preservation of the Licensing Basis for Units 1 and 2 (Section 25.9). After reviewing TVA's program for licensing preservation, the staff concluded that the program, if properly implemented, provides reasonable assurance that any effects on previously reviewed and resolved safety evaluation report topics will be evaluated for WBN Unit 2. An open item was created to track an NRC audit of TVA's Licensing Preservation Program; Open Item 12 in Appendix HH of Safety Evaluation Report, Supplement.

The staff plans to conduct an onsite audit, which will address Open Item 12 in Appendix HH, in accordance with the enclosed audit plan from August 12-14, 2014.

J.Shea If you have any questions, please contact me at 301-415-2048 or by e-mail at Justin.Poole@nrc.gov.

Audit plan cc w/encl: Distribution via Listserv Sincerely, CJ* -j-oY Justin C. Poole, Senior Project Manager Watts Bar Special Projects Branch Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Audit Plan Watts Bar Nuclear Plant, Unit 2 BACKGROUND AND AUDIT BASIS As part of the Watts Bar Nuclear Plant (WBN), Unit 2 operating licensing review reactivation, and consistent with the Commission's staff requirements dated July 25, 2007 (Agencywide Documents Accession Management System (ADAMS) Accession No. ML072060688; SECY-07-0096),

the U.S. Nuclear Regulatory Commission (NRC) staff required the Tennessee Valley Authority (TVA) to develop and implement a licensing basis preservation program to confirm the validity of previously completed NRC safety evaluations to the final WBN Unit 2 design, or to identify topics that require supplemental review. In 2008, the TVA submitted its licensing basis preservation

program, New Generation Development and Construction (NGDC) Procedure PP-20, "Unit 2 Licensing Basis Preservation Program,"

which describes the methods or processes for determining potential changes that could affect Unit 2 licensing basis during the ongoing design and construction activities (ADAMS No. ML083460177).

In April2009 the NRC staff reviewed TVA's submittal and asked for more information and details about the licensing basis preservation program.

In 2009, TVA provided Revision 002 of "Engineering Document Construction Release" (EDCR), which addressed how each Unit 2 design change would be evaluated for licensing-basis impact. Specifically, Attachment J of the EDCR, "Licensing Basis Preservation Review Form," has screening questions to identify potential impact. TVA identified the reviews to be performed for each EDCR issue to ensure that the Unit 2 licensing basis is implemented in the same manner as the corresponding Unit 1 licensing basis to obtain the same conclusion, to the maximum extent practical, as identified in NGDC PP-20. TVA stated that the process in Appendix J addresses the corrective action program plans, special programs, generic communications, exemptions,

reliefs, and other identified in NGDC PP-20. In Supplement 22 of NUREG-0847, "Safety Evaluation Report Related to the Operation of Watts Bar Nuclear Plant (WBN), Unit 2," the NRC staff documented the results of their review of TVA's Program for Maintenance and Preservation of the Licensing Basis for Units 1 and 2 (Section 25.9). After reviewing NGDC PP-20 and EDCR Appendix J the staff concluded that the program, if properly implemented, provides reasonable assurance that any effects on previously reviewed and resolved safety evaluation report topics will be evaluated for WBN Unit 2. NRC audits of TVA's implementation of NGDC PP-20 and EDCR Appendix J is documented as Open Item 12 (Appendix HH of Safety Evaluation Report, Supplement (SSER)).

In 2009, NRC inspectors identified areas where past Title 10, Code of Federal Regulations, Section 50.59 evaluations and screenings based their conclusions upon the unfinished state of Unit 2's facilities.

The inspection report (IR) 05000390/2009002 and 05000391/2009002 confirmed that there are fractional percentages of previous screenings and evaluations that will need to be revisited under the construction interface procedures tied to licensing basis preservation and initiated tracking Problem Evaluation Report (PER) 162088 to ensure that there is a clear reference to this activity within their corrective action program (ADAMS ML091140240).

Enclosure By letter dated June 17, 2011, TVA transmitted an enclosure documenting a self-assessment of its Licensing Basis Preservation Program (ADAMS ML 11186A552).

The June 17, 2011, letter documented TVA's commitment to perform a periodic review of licensing written correction action plans (CAP) and perform a focused self-assessment to ensure that the CAP specified in PER 239111 is implemented effectively.

AUDIT SCOPE As discussed, onsite audits will be performed per Office Instruction LIC-111, "Regulatory Audits,"

to support the NRC staff's safety review of TVA's Licensing Preservation Program as described in Open Item 12 documented in SSER Appendix HH. The purpose of the audit is to obtain and review information regarding how TVA implements its Licensing Preservation Program (NGDC PP-20), including how it has utilized the process from EDCR Appendix J. The onsite audit will have three components:

(1) a review of a list of EDCR Attachment J evaluation forms; (2) selection of a sample of Attachment J evaluation forms covering a variety of technical areas and (3) a detailed review of those evaluation forms where section 4, 5, 6 are answered affirmatively.

INFORMATION NEEDS
