Tennessee Valley Authority 1101 Market Street, LP 3R Chattanooga, Tennessee 37402-2801 R. M. Krich Vice President Nuclear Licensing May 24, 2010 10 CFR 50.4 10 CFR 50.55a ATTN: Document Control Desk U.S. Nuclear Regulatory Commission Washington, D.C. 20555-0001 Browns Ferry Nuclear Plant, Unit 2 Facility Operating License No. DPR-52 NRC Docket No. 50-260

Subject:

American Society of Mechanical Engineers Boiler and Pressure Vessel Code, Section Xl, System Pressure Test Program for the Fourth 10-Year Inspection Interval The Tennessee Valley Authority is submitting the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, Section Xl, System Pressure Test (SPT) Program for the Fourth 10-Year Inspection Interval for Unit 2 of the Browns Ferry Nuclear Plant (BFN). The Code of Record for the Fourth 10-Year Interval SPT Program is the 2004 Edition of the ASME Boiler and Pressure Vessel Code,Section XI. The Fourth 10-Year Interval for BFN, Unit 2, commences on May 25, 2011 and ends on May 24, 2021.

The applicable regulation, 10 CFR 50.55a(g), requires that SPT examinations of ASME components of a water-cooled nuclear power facility meet the requirements of the ASME Section Xl Code. Additionally, 10 CFR 50.55a(g)(4)(ii) requires that the SPT program be updated every 120 months to the latest NRC approved Edition and Addenda of the ASME Section XI Code, which is in effect 12 months prior to the start of the next 120-month Inspection Interval. The enclosed BFN, Unit 2, SPT program update satisfies that requirement.

1.0 Statement of Applicability This program outlines the requirements for performing American Society of Mechanical Engineers (ASME), Boiler and Pressure Vessel Code, Section Xl system pressure tests during the fourth inspection interval for Browns Ferry Nuclear Plant (BFN) Unit 2 systems which are classified ASME Code Class 1, 2 or 3 or equivalent, and contain water, steam or radioactive waste (other than radioactive waste management system).

Pressure tests will be performed in accordance with the ASME Section Xl editions, addenda, and code cases, NRC approved requests for relief and additional provisions specified below or provisions approved by the NRC at a later date. Details concerning performance of system pressure tests are not part of this program description, but are contained in plant surveillance instructions. Performance of pressure tests required because of Repair/Replacement activities will be prescribed and controlled by the work documents performing the Repair/Replacement work.

The requirements of this program are applicable during the fourth 10-year inspection interval which begins on May 25, 2011.

2.0 Purpose This program is designed to meet the requirements of Section XI of the ASME Boiler and Pressure Vessel Code which pertain to the inservice pressure testing of pressure retaining Code Class 1, 2 and 3 components, and pressure testing required following Repair/Replacement activities, at BFN Unit 2 during the fourth inspection interval. Compliance with Section Xl of the ASME Boiler and Pressure Vessel Code is required by Part 50 of Title 10 of the Code of Federal Regulations.

3.0 Inspection Interval and Inspection Periods The fourth 10-year inspection interval for BFN Unit 2 begins on May 25, 2011. The fourth 10-year inspection interval will be divided into three inspection periods as shown below and will end in May 2021. The dates of the three inspection periods are as follows:

First inspection period May 25, 2011 to May 24, 2014 Second inspection period -

May 25, 2014 to May 24, 2018 Third inspection period May 25, 2018 to May 24, 2021 E-5

4.0 Codes of Record 4.1 Primary Code Edition This inservice system pressure test program is prepared to meet the requirements of Section Xl of the ASME Boiler and Pressure Vessel Code, 2004 Edition.

4.2 Adopted Portions of Later Editions and Addenda None.

4.3 Adopted ASME Section XI Code Cases (as approved by NRC Regulatory Guide 1.147)

Code Case N-566 Corrective Actions for Leakage Identified at bolted Connections - for systems containing boron for the purpose of controlling reactivity Code Case N-686 -

Alternative Requirements for Visual Examinations, VT-1, VT-2, and VT-3 5.0 Requests for Relief None.
