3. TVA letter to the NRC dated February 8, 2008, Watts Bar Nuclear Plant (WBN) - Unit 2 - Final Safety Analysis Report (FSAR) Red-Line for Unit 2 This letter transmits WBN Unit 2 FSAR Amendment 100 (A100), which reflects changes made since the issuance of Amendment 99 on May 27, 2010 (Reference 1). contains a Summary Listing of FSAR sections and corresponding Unit 2 change package numbers associated with the A100 FSAR changes. Most of these changes were the result of resolutions to Requests for Additional Information. A portion of the changes provided in A100 satisfies a commitment made in letter dated May 24, 2010 (Reference 2) to incorporate Instrumentation Setpoint Methodology, which is provided in FSAR Chapter 7.0, Instrumentation and Controls. A revision to the WBN Unit 2 Technical Specifications will be provided via separate letter to provide consistency with the setpoint methodology changes provided in A100 and Technical Specification Tracking Form 493.

With this letter, TVA modifies a commitment previously made in TVA letter dated February 8, 2008 (Reference 3). Modify the previous commitment from, Prior to Unit 2 fuel load, TVA will submit a combined Unit 1 and Unit 2 UFSARs, to state TVA will submit a combined Unit 1 and Unit 2 FSAR with the first update of the Unit 1 UFSAR after Unit 2 is licensed.

Each assembly will be operated four times, once at cold no flow, once at cold full flow, once at hot not flow and hot full flow conditions. Those assemblies whose trip times fall outside a certain tolerance will be tested an additional 3 times at each failed test condition. Thus each assembly will be adequately tested to verify that the assemblies are properly functioning.
