Approved Contents 2.0 Certificate of Compliance No.1032 Amendment No. 76 Appendix B 2-57 2.5 Burnup and Cooling Time Qualification Requirements 2.5.1 Burnup and cooling time limits for fuel assemblies authorized for loading into the MPC-32ML are provided in Table 2.5-1. Burnup and cooling time limits for fuel assemblies authorized for loading according to only the alternative loading patterns shown in Figures 2.30-1 through 2.3-9 (MPC-37) and Figures 2.3-10 through 2.3-13 (MPC-89) are provided in Table 2.5-2. Burnup and cooling time combinations in Table 2.5-2 also apply for 10x10J fuel loaded according to heat load regions shown in Tables 2.3-2A, 2.3-2B and 2.3-4.

The burnup and cooling time for every fuel loaded into the MPC-32 ML must satisfy the following equation:

Ct = A Bu3 + BBu2 + C Bu + D

where, Ct

= Minimum cooling time (years)

Bu

= Assembly-average burnup (MWd/mtU)

A,B,C,D =Polynomial coefficients listed in the above tTables 2.5-1 and 2.5-2 Minimum cooling time must also meet limits specified in Table 2.1-1. If the calculated Ct is less than the cooling time limit in Table 2.1-1, the minimum cooling time in Table 2.1-1 is used.

2.5.2 Burnup and cooling time limits for fuel assemblies authorized for loading into the MPC-37P and MPC-44 are provided in Table 2.5-3.

The burnup and cooling time for every fuel assembly loaded into the MPC-37P and MPC-44 must satisfy the following equation:

Ct = A Bu4 + B Bu3 + C Bu2 + D Bu + E

where, Ct

= Minimum cooling time (years),

Bu

= Assembly-average burnup (MWd/mtU),

A, B, C, D, E

= Polynomial coefficients listed in Table 2.5-3.

2.5.3 Alternative burnup and cooling time limits for fuel assemblies authorized for loading into the MPC-37P and MPC-37 are provided in Table 2.5-4 and Table 2.5-5.

2.5.4 Burnup and cooling time limits for Assembly Class 10x10J loaded according to Tables 2.3-2A, 2.3-2B and 2.3-4 are provided in Table 2.5-6.

1. For BLEU fuel, coefficient D is increased by 1.

2.

For calculation of the minimum cooling time for 10x10J fuel that is loaded in accordance with Table 2.3-2A, 2.3-2B and 2.3-4 or Figures 2.3-10 through 2.3-13, thean assembly-average burnup must be increased by 10,000 MWd/mtU and 5,000 MWd/mtU, respectively.
