NED0-24146A 4.5 RESULTS OF THE CHASTE 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 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 channel wetting 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 maximum permissible planar power where required to satisfy the requirement's of 10CFR50.46 acceptance criteria.

The CHASTE resulta presented are:

Peak Cladding Temperature versus time e

o Peak Cladding Temperature versus Break Ares e

Peak Cladding Temperature and Peak Local oxidation versus Planar Average Exposure for the most limiting break size.

I l

e Maximum Averrage Planar Heat Generation Rate (MPLHGR) versus Planar Average Exposure for the most limiting break size A summary of the analytical results is given in Table 2.

Table 3 lists the figures provided for this analysis. The MPLBGR values for each fuel type for D2,3/QC1,2 are presented in Tables 4A through 4T.

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 / SCAT / SAFE /DBA-REFLOOD/ CHASTE. Break size: DBA.

4-3

T NEDO-24146 b.

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

Break sizes: 1.0 ft f_ A < DBA.

b.

Small Break Methods (SBM). SAFE /non-DBA REFLOOD. Beat 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 2

non-DBA-REFLOOD. Break sizes: A < 1.0 ft,
