3. INPUT TO ANALYSIS A li.t of the significant plant input parameters to the LOCA analysis is presented in Table 3-1.

Table 3-1 SIGNIFICANT INPUT PARAMETERS TO THE LOSS-OF-COOLANT ACCIDENT ANALYSIS Plant Parameters:

Core Thermal Power 3440 MWt, which corresponds to 105% of rated steam flow Vessel Steam output 14.05 x 106 lbm/h, which corresponds to 105% of rated steam flow Vessel Steam Dome Pressure 1055 psia Recirculation Line Break Area for Large Breaks - Discharge 1.9 ft2 (DBA)

- Suction 4.1 ft (DBA)

Number of Drilled Bundles 360 Fuel Parameters:

Peek Technical Initial-Specification Design Minimum Linear Heat Axial Critical Fuel Bundle Generation Rate Peaking Power Fuel Type Geometry (kW/ft) Factor Ratio A. IC Type 2 7x7 18.5 1.5 1.2 B. IC Type 3 7x7 18.5 1.5 1.2 C, 8D274L 8x8 13.4 1.4 1.2 D. 8D274H 8x8 13.4 1.4 1.2 E. LTA260 8x8 13.4 1.4 1.2 F. 8DRB284 8x8R 13.4 1.4 1.2 G. F8DRB284H 8x8R 13.4 1.4 1.2 H. P8DRB285 8x8R 13.4 1.4 1.2

• To account for the 2% uncertainty in bundle power' required by Appendix K, the SCAT calculation is performed with an MCPR of 1.18 (i.e., 1.2 divided by 1.02) for a bundle with an initial MCPR of 1.20.
