Attachment 6 to Holtec Letter 5014917 Approved Contents 2.0 2.4.3 Burnup Limits as a Function of Cooling Time for ZR-Clad Fuel The maximum allowable ZR-clad fuel assembly average burnup varies with the minimum required fuel assembly cooling time. Tables 2.4-3 and 2.4-4 provide for each MPC the allowable maximum burnup based on the assemblys particular cooling time.
2.4.3.1 Linear interpolation of burnups between cooling times is permitted. For example, the allowable burnup for a cooling time of 4.5 years may be interpolated between those burnups calculated for 4 year and 5 years.
2.4.3.2 Calculated burnup limits shall be rounded down to the nearest integer.
2.4.3.3 Calculated burnup limits greater than 68,200 MWD/MTU for PWR fuel and 65,000 MWD/MTU for BWR must be reduced to be equal to these values.
The maximum allowable fuel assembly average burnup varies with the following parameters:
$ Minimum fuel assembly cooling time
$ Maximum fuel assembly decay heat
$ Minimum fuel assembly average enrichment The maximum allowable ZR-clad fuel assembly average burnup for a given MINIMUM ENRICHMENT is calculated as described below for minimum cooling times between 3 and 20 years using the maximum permissible decay heat determined in Section 2.4.1 or 2.4.2. Different fuel assembly average burnup limits may be calculated for different minimum enrichments (by individual fuel assembly) for use in choosing the fuel assemblies to be loaded into a given MPC.
2.4.3.1 Choose a fuel assembly minimum enrichment, E235.
2.4.3.2 Calculate the maximum allowable fuel assembly average burnup for a minimum cooling time between 3 and 20 years using the equation below.
Bu = (A x q) + (B x q2) + (C x q3) + [D x (E235)2] + (E x q x E235) + (F x q2 x E235) + G Where:
Bu = Maximum allowable average burnup per fuel assembly Certificate of Compliance No. 1014 Amendment No. 165 Appendix B-100U 2-28 1 of 21
Attachment 6 to Holtec Letter 5014917 Approved Contents 2.0 (MWD/MTU) q = Maximum allowable decay heat per fuel storage location determined in Section 2.4.1 or 2.4.2 (kW)
E235 =Minimum fuel assembly average enrichment (wt. % 235U)
(e.g., for 4.05 wt.%, use 4.05)

2.4.3.4 Calculated burnup limits greater than 68,200 MWD/MTU for PWR fuel and 65,000 MWD/MTU for BWR must be reduced to be equal to these values.
2.4.3.5 Linear interpolation of calculated burnups between cooling times for a given fuel assembly maximum decay heat and minimum enrichment is permitted. For example, the allowable burnup for a cooling time of 4.5 years may be interpolated between those burnups calculated for 4 year and 5 years.
2.4.3.6 Each ZR-clad fuel assembly to be stored must have a MINIMUM ENRICHMENT greater than or equal to the value used in Step 2.4.3.2.
2.4.4 When complying with the maximum fuel storage location decay heat limits, users must account for the decay heat from both the fuel assembly and any NON-FUEL HARDWARE, as applicable for the particular fuel storage location, to ensure the decay heat emitted by all contents in a storage location does not exceed the limit.
