- 4. CONDITIONS This certificate is conditional upon fulfilling the requirements of 10 CFR Part 71, as applicable, and the conditions specified below.
5.
(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 with either a standard set design or a LW design, and the personal barrier. The packaging has two cavity lengths, designated as XL and SL.
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, stee l 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 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, 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.

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 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 types of packaging, designated as Types XL and SL. The LW impact limiter set is fabricated of aluminum rings and unidirectional crush material completely enclosed by an all-welded stainless-steel skin and may only be used with the Type SL F-24 M configuration. Both versions of impact limiters are attached to the top and bottom of the packaging with 16 bolts each.
The personal barrier is a packaging component when in use, providing a physical barrier to prevent access to hot areas of the package.
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.
The maximum packaging weights of the SL and XL versions are approximately 25 8,000 pounds and 246, 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).
