  • 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.

- 4.5RESULTS OF Tile CllASTE ANALYSIS This code is used, with. suitable inputs from the other codes, to calculate the fuel cladding heatup rate, peak cladding temperature, peak local cladding oxidation, and core-wide metal-water react ton for large breaks. The detailed fuel model in CilASTE considers transient gap conductance, clad swelling and rupture, and metal-water reaction. The empirical core spray heat transfer and channel wetting -correlations are built into-CHASTE, which solves the transient

~

'I

- heat' transfer equations for the entire LOCA transient at a single axial plane

. in a single fuel assembly. -Iterative applications of CHASTE determine the maximum permissible planar power where required to satisfy the requirements of 10CFR50.46 acceptance criteria.

The CilASTE rcaults presented are:

e Peak Cladding Temperature versus time e

Peak Cladding Temperature versus Break Area i

Peak Cladding Temperature and Peak Local Oxidation versus Planar e

Average Exposure for the most limiting break size j

i e

Maximum Average Planar-Heat Generation Rate (MAPLHCR) versus Planar

- Average Exposure for the most limiting break size Rod Perforation Time and Temperature e

= e

- Hot Rod Location A summary of the analytical results is given in Table 3.

Table 4 lists the figures provideu.for this analysis. ILe MAPLHGR values for each fuel type in the FitzPatrick core are presented in Tables SA'through.5J.
