• 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.

4.5 RESULTS OF THE 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 7

i

' oxidation, and core-wide metal-water reaction for large breaks. The detailed fuel model in CHASTE considers transient gap conductance, clad swelling and

rupture, and metal-water reaction. The empirical core spray heat transfer and I

channel vetting correlations are built into CHASTE, which solves the transient heat transfer equations for the entire LOCA transient at a single axial plane in a single fuel assembly. Iterative applications of CHASTE determine the i

maximum permissible planar power where required to satisfy the requirements of 10CFR50.46 acceptance criteria.

The CHASTE results presented are:

i

! e Peak Cladding Temperature versus time i

e Peak Cladding Temperature versus Break Area I

t e Peak Cladding Temperature and Peak Local Oxidation versus Planar -

l Average Exposure for the most limiting break size e Maximum Average Planar Heat Generation Rate (MAPLHGR) versus Planar Average Exposure for the most limiting break size A summary of the analytical results is given in Table 4-1. Table 4-2 lists the figures provided for this analysis. The MAPLHGR values for each fuel '

type in the PB-3 core are presented in Tables 4-3a through 4-31. .

NEDO-24082 4.6 METHODS In the following sections, it will be useful to refer to the methods used to analyze DBA, large breaks, and small breaks. For jet-pump reactors, these are defined as follows:

a. DBA Methods. LAMB / S CAT / SAFE / DBA- REFLOOD/ CIIASTE . Break size: DBA.

b. Large Break Methods (LBM). LAMB / SCAT / SAFE /non-DBA REFLOOD/ CHASTE.

2 Break sizes: 1.0 ft 5,A < DBA.

c. Small Break Methods (SBM). SAFE /non-DBA REFLOOD. Heat transfer coefficients: nucleate boiling prior to core uncovery, 25 Btu /hr-ft - *F after recovery, core spray when appropriate. Peak cladding temperature and peak local oxidation are calculated in non-DBA-REFLOOD. Break sizes A 5,1.0 ft2, 4-4
