"CCS is a supporting system to other safe shutdown systems. Two redundant trains per unit are available. For each unit, Train A consists of two available CCS pumps and the associated valves, piping, instrumentation and heat exchanger (Heat Exchanger A for Unit I and Heat Exchanger B for Unit 2). Train B is common for both units and consists of one CCS pump and the associated valves, piping, instrumentation and heat exchanger (Heat Exchanger C).

Each unit has a CCS pump (1A-A for Unit 1 and 2A-A for Unit 2) which is aligned to that unit's Train A header and which receives electrical power from Train A. Each unit has another CCS pump (1 B-B for Unit 1 and 2B-B for Unit 2) which can be aligned to that unit's Train A header but which receives electrical power from Train B. These pumps (1 B-B and 2B-B)

10. Section are normally aligned to the Train A piping system for that unit but can be 2-110-10 9.2.2.2 aligned to the common Train B piping system. The C-S pump, which normally receives Train B electrical power while serving as the common Train B CCS pump, is capable of being powered from a Train A power source.

During normal full power operation, with all CCS equipment available, CCS pumps 1A-A and 1 B-B and Heat Exchanger A are aligned with Unit 1, Train 1A ESF and miscellaneous equipment. CCS pumps 2A-A and 2B-B and Heat Exchanger B are aligned with Unit 2 Train 2A ESF and miscellaneous equipment. CCS pump C-S and Heat Exchanger C are aligned with both Unit 1, Train 1B and Unit 2, Train 2B.

CCS pump 1B-B can be used as additional capacity for Train 1A, as required, or as a replacement for CCS pumps 1A-A or C-S, if one should be out of service. CCS pump 2B-B can be used as additional capacity for Train 2A as required or as a replacement for CCS pumps 2A-A or C-S, if one should be out of service."

3. On Page 15.4-4 (A109), insert new verbiage between the fifth complete paragraph and the beginning of sixth partial paragraph at the bottom of the page. The new verbiage is as follows:

"WCAP-16009-P-A [49] states that the ASTRUM methodology is based on the frozen code version WCOBRA/TRAC MOD7A, Revision 6. WCOBRAITRAC MOD7A, Revision 8-T2 was used for the execution of ASTRUM Uncertainty Studies for Watts Bar Unit

2. The confirmatory analysis (paragraph "2) Determination of Plant Operating Conditions") were executed with WCOBRAITRAC MOD7A Revision 7.

The Nuclear Regulatory Commission (NRC) approved Westinghouse Best-Estimate Loss-of-Coolant Accident (BELOCA)

ASTRUM methodology [49] is based on the PAD 4.0 fuel performance code [51]. PAD 4.0 was licensed without explicitly considering fuel thermal conductivity degradation (TCD) with burnup. Explicit modeling of TCD in the fuel performance code leads directly to increased fuel temperatures (pellet radial average temperature) as well as other fuel performance related effects beyond beginning of-life. Since PAD provides input to the large-break LOCA analysis, this will tend to increase the stored

30. Section energy at the beginning of the simulated large-break LOCA event. 2-110-30 (contd.) 15.4 This in turn leads to an increase in Peak Cladding Temperature (PCT) if there is no provision to credit off-setting effects. In addition, a different fuel thermal conductivity model in WCOBRAITRAC and HOTSPOT was used to more accurately model the fuel temperature profile when accounting for TCD.

In order to mitigate the impact of the increasing effect of pellet TCD with burnup, the large-break LOCA evaluation of second/third Cycle fuel utilized reduced peaking factors from those shown directly in FSAR Table 15.4-19. The reduced peaking factors are limited to the following application: Burndown credit for the hot rod and hot assembly is taken for higher burnup fuel in the second/third cycle of operation. The Watts Bar Unit 2 peaking factor values utilized in this analysis are shown in Table 15.4-24. Note that the beginning to middle of life values are retained at their direct Table 15.4-19 values.

It should be noted that evaluation of fuel in its second/third cycle of irradiation is beyond the first cycle considered in the approved ASTRUM Evaluation Model (EM), but was considered in the analysis when explicitly modeling TCD to demonstrate that conformance to the acceptance criteria is met for the second/third cycle fuel.

Therefore, the approved sampling range was expanded to bound the Watts Bar 2 plant-specific data."

The conservatively low containment backpressure from this LOTIC-2 study is bounding since the core stored energy increases when explicitly modeling fuel TCD, which would tend to increase energy released through the break and hence increase the containment pressure."
