Fuel assemblydecay heat limits for regionalized loading are specified in Section 2.4.2 for VENTILATED OVERPACK, and Section 2.4.5 for UNVENTILATED OVERPACK. Fuel assemblies used in regionalized loading shall meet all other applicable limits specified in Tables 2.1-1 through 2.1-3.
2.2 Violations If any Fuel Specifications or Loading Conditions of 2.1 are violated, the following actions shall be completed:

The method to calculate the limits and verify compliance, including examples, is provided in Chapter 12 of the HI-STORM 100 FSAR.
2.4.1 Uniform Fuel Loading Decay Heat Limits for ZR-clad fuel for VENTILATED OVERPACK Table 2.4-1 provides the maximum allowable decay heat per fuel storage location for ZR-clad fuel in uniform fuel loading for each MPC model.

Q(X) = 2 x Q0 / (1 + Xy) y = 0.23 / X0.1 q2 = Q(X) / (n1 x X +n2) q1 = q2 x X Where:
Q0 = Maximum uniform storage MPC decay heat (34 kW)
X = Inner region to outer region assembly decay heat ratio (0.5 X 3) n1 = Number of storage locations in inner region from Table 2.4-2.
n2 = Number of storage locations in outer region from Table 2.4-2.
Allowable heat loads for Damaged Fuel and Fuel Debris in regionalized loading are shown in Table 2.4-5.
Optional loading patterns for MPC-68M are shown in Figures 2.4-1 through 2.4-4.

Approved Contents 2.0 Certificate of Compliance No. 1014 Amendment No. 165 Appendix B 2-54 2.4.3 Burnup Limits as a Function of Cooling Time for ZR-Clad Fuel for VENTILATED OVERPACK 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.
- 3.
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 valuesThe 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 2 and 40 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 2 and 40 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 =

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.
3.4.12.4.4 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.
2.4.5 Fuel Loading Decay Heat Limits for UNVENTILATED OVERPACK Tables 2.4-6a and 2.4-6b provide the maximum allowable decay heat per fuel storage location for MPC-68M in an UNVENTILATED OVERPACK.
A minor deviation from the prescribed loading pattern in an MPCs permissible contents to allow one slightly thermally-discrepant fuel assembly per quadrant to be loaded as long as the peak cladding temperature for the MPC remains below the ISG-11 Rev 3 requirements is permitted for essential dry storage campaigns to support decommissioning.

i.e. Any reduction of total allowable heat load in Region 1 must be compensated by an equivalent addition in Region 2.
General Notes -
- 1. Any assembly with a Heat Load less than the limits defined above can be loaded in the applicable cell, provided it meets all other CoC requirements.

- 1.
The temperature of 80o F is the maximum average yearly temperature for the VENTILATED OVERPACK. The temperature of 70°F is the maximum average yearly temperature for the UNVENTILATED OVERPACK.
- 2.
The allowed temperature extremes, averaged over a 3-day period, shall be greater than -40o F and less than 125o F.
- 3.
- a.
For storage in freestanding OVERPACKs, the resultant horizontal acceleration (vectorial sum of two horizontal Zero Period Accelerations (ZPAs) at a three-dimensional seismic site), GH, and vertical ZPA, GV, on the top surface of the ISFSI pad, expressed as fractions of g, shall satisfy the following inequality:
GH + GV where is either the Coulomb friction coefficient for the cask/ISFSI pad interface or the ratio r/h, where r is the radius of the cask and h is the height of the cask center-of-gravity above the ISFSI pad surface. The above inequality must be met for both definitions of,
but only applies to ISFSIs where the casks are deployed in a freestanding configuration. Unless demonstrated by appropriate testing that a higher coefficient of friction value is appropriate for a specific ISFSI, the value used shall be 0.53. If acceleration time-histories on the ISFSI pad surface are available, GH and GV may be the coincident values of the instantaneous net horizontal and vertical accelerations. If instantaneous accelerations are used, the inequality shall be evaluated at each time step in the acceleration time history over the total duration of the seismic event.
If this static equilibrium based inequality cannot be met, a dynamic analysis of the cask/ISFSI pad assemblage with appropriate recognition of soil/structure interaction effects shall be performed to ensure that the casks will not tip over or undergo excessive sliding under the sites Design Basis Earthquake.
