Approved Contents 2.0 2-50 2.4.2 Regionalized Fuel Loading Decay Heat Limits for ZR-Clad Fuel The maximum allowable decay heat per fuel storage location for intact fuel assemblies in regionalized loading is determined using the following equations:
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.
An optional regionalized loading pattern for MPC-68M is shown in Figure 2.4-1.

Approved Contents 2.0 2-52 2.4.3 Burmup Limits as a Function of Cooling Time 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 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 = Maximum allowable average burnup per fuel assembly (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)
A through G = Coefficients from Tables 2.4-3 and 2.4-4 for the applicable fuel assembly array/class and minimum cooling time 2.4.3.3 Calculated burnup limits shall be rounded down to the nearest integer.
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 in.terpolated 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.

Approved Contents 2.0 2-53 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.

LIST OF ASME CODE ALTERNATIVES FOR HI-STORM 100 CASK SYSTEM Component Reference ASME Code Section/Article Code Requirement Alternative, Justification & Compensatory Measures MPC basket supports and lift lugs NB-1130 NB-1132.2(d) requires that the first connecting weld of a nonpressure-retaining structural attachment to a component shall be considered part of the component unless the weld is more than 2t from the pressure-retaining portion of the component, where t is the nominal thickness of the pressure-retaining material.
NB-1132.2(e) requires that the first connecting weld of a welded nonstructural attachment to a component shall conform to NB-4430 if the connecting weld is within 2t from the pressure-retaining portion of the component.
The MPC basket supports (nonpressure-retaining structural attachments)and lift lugs (nonstructural attachments (relative to the function of lifting a loaded MPC) that are used exclusively for lifting an empty MPC) are welded to the inside of the pressure-retaining MPC shell, but are not designed in accordance with Subsection NB. The basket supports and associated attachment welds are designed to satisfy the stress limits of Subsection NG and the lift lugs and associated attachment welds are designed to satisfy the stress limits of Subsection NF, as a minimum. These attachments and their welds are shown by analysis to meet the respective stress limits for their service conditions. Likewise, non-structural items, such as shield plugs, spacers, etc. if used, can be attached to pressure-retaining parts in the same manner.
MPC NB-2000 Requires materials to be supplied by ASME-approved material supplier.
Materials will be supplied by Holtec-approved suppliers with Certified Material Test Reports (CMTRs) in accordance with NB-2000 requirements.
MPC NB-2121 Provides permitted material specification for pressure-retaining material, which must conform to Section II, Part D, Tables 2A and 2B Certain duplex stainless steels are not included in Section II, Part D, Tables 2A and 2B. UNS S31803 duplex stainless steel alloy is evaluated in the HI-STORM 100 FSAR and meets the required design criteria for use in the HI-STORM 100 system per ASME Code Case N-635-1.
