3. INPUT TO ANALYSIS A list 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 344) MWt, which corresponds to 105% of rated steam flow Vessel Steam Output 14.05 x 106 lbu/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 ft2 (DBA)

Number of Drilled Bundles 432 Fuel Parameters:

• 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.
