02/25/2011 Engineering - I and C RAI Response - I and C NRR 111621260 (Letter Item 9) - This item will be corrected by a design change based on the following:

The Unit 1/Unit 2 Eagle 21 configuration has a sufficient number of spare Narrow Range (NR) and Wide Range (WR) RTD inputs available on the installed ERI-01 and ERI-02 boards to wire these spare inputs to the active channels. The spare input will provide the parallel resistance to resolve the problem. The WR RTD inputs provide the same input impedance as the NR RTD inputs. Jumpers will be installed at the Eagle 21 termination frame to provide a parallel connection from each existing NR RTD input to an existing spare input, thus simulating the hardware connection for shared RTDs. Therefore, as configured, the Rack 2 Loop Calculation Processor (LCP) will provide the correct temperature calculation for the NR RTDs. The design change will be issued by April 29, 2011.

112249893 Part III, Sections 2.3 and 3.4.3 provide qualitative statements regarding the need to control RCS pressure to maintain sub-cooling margin such that natural circulation would not be adversely affected by large bubble formation in the reactor vessel. Both statements convey the desired information, but for consistency Section 3.4.3 will be revised to say minimize void formation rather than prevent void formation and thereby be consistent with Section 2.3.

PRIOR to fuel load Engineering - I and C FSAR RAI NRR 112249865 A review of the HVAC configuration control drawings (47A381 series, 47W866 series, and 47W920 series) has been performed to determine the correct identification number and fire resistance rating of the damper. The correct damper number is 1-ISD-31-2516 and correct fire rating of the damper is 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />. A review of the damper information contained in Table 14.8.2 against the Damper tables provided in Part VI has also been completed. The information in the tables (Table 14.8.2 and Part VI Damper tables) has been verified and the discrepancies corrected. These changes will be incorporated into the next revision to the Unit 1/Unit 2 As-Designed FPR. (Letter Item 9. [NRC Question RAI FPR II-19])

(Item 5. of Enclosure 2. of letter T02 110506 001)

Engineering - I and C FSAR RAI NRR 112249861 Part II and Part VI were corrected to show the damper (2-ISD-31-3872) is in the fire barrier separating rooms 713.0-A29 (not 737-A9) and 737.0-A8.

112249919 TVAs response to Letter Item 42 [NRC Question RAI FPR V-3] states:

[1] Part IV, Section 3.3 is incorrect. The second sentence should read The number in ( ) is the number available for shutdown. This deletes the reference to Unit 1 only.

[2] A review of the FPR revealed three other places where the discussion concerns both units:

1. Table 14.3, item 14.3.c should read: Unit 1 and 2 Containment Purge Air Exhaust Filters,

2. Part II, Section 14.3.1.b.1 of the FPR should say For either Reactor Building.

3. Part III, section 4.7 is incorrect. The third paragraph should read: The CCS system provides cooling for the following safe shutdown equipment per unit. The CCS system equipment is for both units.

Engineering - I and C RAI Response - I and C NRR 112249939 As described in Enclosure 2 to TVA letter to NRC dated March 31, 2011, most of WBN Unit 2 operator manual actions are preventative rather than reactive. That is, they are driven by procedure rather than reacting to changing plant conditions as indicated by instrumentation and alarms. While there are some actions that are taken in response to the fire itself (de-energize electrical board that is on fire), most WBN Unit 2 actions are in response to tripping the reactor.

08/06/2010 Unit 2 Licensing RAI Response -

Radiological Emergency Plan NRR 112046353 The FSAR will be revised to eliminate the adjustment factors and use GELC results directly.

Specifically, Table 11.3-10 (Unit 2 only) dose values for Noble Gases and Iodines/Particulates will be revised. In addition, due to elimination of the terrain adjustment factors, the highest dose pathway becomes vegetable ingestion instead of the cow milk with feeding factor. Doses reflected in this table will be of one unit (Unit 2) without a Tritium Producing Core. These changes will be submitted as part of Unit 2 FSAR, Amendment 103.
