(a) Packaging (1)
Model No.:
HI-STAR 100MB (2)
Description The HI-STAR 100MB packaging consists of the following major components: the packaging body, the multi-purpose canister (MPC) or the fuel basket, the impact limiters, and the personal barrier. The packaging has two cavity lengths, designated as XL and SL. The impact limiters have two sets of designs, a standard set and the other designated as LW.
The packaging body, comprised of a nickel steel shell welded to nickel steel bottom and top flanges, provides the containment boundary, the helium retention boundary, gamma and neutron shielding and heat rejection capability of the package. The containment system consists of the inner shell, bottom and top flanges, top closure lid(s), closure lid inner O-ring seal, vent and drain port cover and inner seals, and bolts for the closure lids and port covers.
The outer surface of the inner shell is buttressed with a layered combination of lead, steel and Holtite B neutron shielding material. The top flange has bolted closure lid(s) with machined concentric grooves for elastomeric seals. The packaging body also features collapsible trunnions.
The Multipurpose Canister (MPC), a welded cylindrical structure with flat ends, consists of a honeycombed fuel basket made from panels of Metamic-HT, a baseplate, canister shell, lid and closure ring. Fuel spacers may be used to minimize the assembly to MPC lid gap. There is only one MPC model, the MPC-32M-T, designated for use with this packaging. With the MPC configuration, applicable only to the Type XL package, the HI-STAR 100MB utilizes a single bolted lid. to Holtec Letter 5026012 Page 1 of 5

OF 5.(a)(2) Description (continued)
The fuel basket, made of Metamic-HT both as a structural and neutron absorber material, exists in two configurations, the F-24 M and F-32 M. The F-24 M basket has flux traps. With the fuel basket configuration, only applicable to the Type SL package, the HI-STAR 100 MB has two bolted lids, with each lid equipped with two concentric seals.
The HI-STAR 100MB also includes variants of the above casks designated as Type XL-MSC and Type SL-MSC. The MSC represents the monolithic shield cylinder version of these casks which uses neutron absorbers located in axial holes drilled into the MSCs. The Type SL-MSC contains fuel baskets made of Metamic-HT in two configurations, the F-24M CBS and F-32MCBS, and has two bolted lids. The Type XL-MSC contains MPCs, as described above, but includes a wider set of MPCs: MPC-32M, MPC-24, MPC-32 (including Version 1), MPC-68 (including Version 1), MPC-68M, MPC-32M CBS, MPC-68M CBS, and Diablo Canyon MPC-32. Similarly to the standard Type XL, the Type XL-MSC has a single bolted lid.
Two identical AL-STAR impact limiters are attached to the top and bottom of the packaging with 16 bolts each. The standard impact limiter set is fabricated of aluminum honeycomb crush material completely enclosed by an all-welded stainless steel skin and may be used with both Cask Types XL and SL. The Version LW impact limiter set is fabricated of aluminum casting and unidirectional crush material completely enclosed by an all-welded stainless steel skin and may only be used with the Cask Type SL F-24 M configuration.
The personal barrier, placed over the package lying in a horizontal orientation during transport, is a packaging component when in use, providing a physical barrier to prevent access to hot areas of the package.
The HI-STAR 100MB is designed for maximum heat loads of 32 kW (package with the F-32M or F-24M basket) or 29 kW (package loaded with the MPC-32M). The HI-STAR 100MB MSC is designed for maximum heat loads of 35.76 kW with the bare basket, and 34 kW with the MPC.
For the HI-STAR 100 MB, the packaging body cavity is approximately 165 3/8 inches long (SL configuration) or 191 1/8 inches long (XL configuration) with respective total lengths of the packaging body of 197 inches or 212 inches, respectively. Both versions have an inside diameter of 68 3/4 inches, and an outer diameter of approximately 99 1/4 inches without impact limiters, and 124 inches with the impact limiters installed.
For the HI-STAR 100MB MSC the packaging body cavity is approximately 165 3/8 inches long (SL-MSC configuration) or 191 1/8 inches long (XL-MSC configuration) with respective total lengths of the packaging body of 196 1/8 inches or 210 5/8 inches, respectively. Both versions have an inside diameter of 68 3/4 inches, and an outer diameter of approximately 98 1/2 inches without impact limiters, and 124 inches with the impact limiters installed.
The maximum packaging weights of the SL and XL versions are approximately 258,000 pounds and 266,000 pounds respectively. The package, as configured for transport, i.e.,
including impact limiters, weighs from 288,000 lbs (SL version) to 300,000 lbs (XL version).
The maximum weights of the SL-MSC and XL-MSC versions are approximately 268,000 lbs and 288,000 lbs respectively. The package as configured for transport, i.e., including impact limiters, weighs from approximately 258,000 to 310,000 lbs.
