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 100

(2) Description

The Model No. HI-STAR 100 package is a canister based system, with either a Multi-Purpose Canister (MPC) or a Greater -Than - Class C Waste Canister (GWC), inside an overpack designed for transportation of irradiated nuclear fuel or reactor related waste (reactor internals). The overpack, which provides containment boundary, helium retention boundary, gamma and neutron radiation shielding, as well as heat rejection capability, has an outer diameter of approximately 96 inches, without impact limiters, and approximately 128 inches with impact limiters. The Model No. HI-STAR 100 includes two versions: the HI-STAR 100 Version HB (also referred to as the HI-STAR HB) and the HI-STAR 100 Version HB GTCC (also referred to as HI-STAR HB GTCC).

The maximum gross weight of the Model No. HI-STAR 100 package, as presented for shipment, shall not exceed 282,000 pounds; the HI-STAR HB has a maximum gross weight of 189,300 pounds, and the HI-STAR HB GTCC has a maximum gross weight of 145,100 pounds.

Multi-Purpose Canister

There are seven MPC models designated as the MPC-24, MPC-24E, MPC-24EF, MPC-32, MPC-68, MPC-68F, and MPC-HB. All MPCs have identical exterior dimensions, except 1) the MPC-24E/EFs and the MPC-32s custom-designed for the Trojan and the Diablo Canyon NRC FORM 618 U.S. NUCLEAR REGULATORY COMMISSION (8-2000) 10 CFR 71 CERTIFICATE OF COMPLIANCE FOR RADIOACTIVE MATERIAL PACKAGES

plants respectively, approximately nine inches shorter than the generic MPC design; and 2) the MPC-HB custom-designed for the Humboldt Bay plant, approximately 76 inches shorter than the generic MPC design;

The MPC is a welded cylindrical structure with flat ends, consisting of a honeycombed fuel basket, baseplate, canister shell, lid, and closure ring. The outer diameter (68-3/8 inches) and cylindrical height (190-1/4 inches) of each generic MPC is fixed. A steel spacer is used with the Trojan and Diablo Canyon MPCs to ensure the MPC-overpack interface is bounded by the generic design. The MPC-HBs are transported in the HI-STAR HB overpack. The fuel basket designs vary based on the MPC model.

Multi-Purpose Non-Fuel Waste Canister

The GWC is a welded cylindrical structure with flat ends, consisting of an internal structure, a baseplate, canister shell, lid, and an optional closure ring. The outer diameter and height of each generic GWC match those of the generic MPCs. The Humboldt Bay GWC-HB model requires a closure ring; its containment system is constituted by the GWC baseplate, the canister shell, the lid, the closure ring, and the vent and drain port cover plates. The GWC-HB canister is transported in the HI-STAR HB GTCC overpack.

Overpack

The HI-STAR 100 overpack is a multi-layer steel cylinder, with an internal diameter of 68-3/4 inches and an outer diameter of 96 inches, that includes a welded baseplate and bolted lid (closure plate). The inner shell of the overpack forms an internal cylindrical cavity to house the MPC or the GWC. The outer surface of the overpack inner shell is buttressed with intermediate steel shells for radiation shielding.

The HI-STAR 100 MPC overpack closure plate incorporates a dual O-ring design to ensure its containment function; the containment system consists of the overpack inner shell, bottom plate, top flange, top closure plate, top closure inner O-ring seal, vent port plug and seal, and drain port plug and seal, and their respective welds.

The HI-STAR 100 HB GTCC overpack closure plate does not include containment seals, nor the corresponding inter-seal leak test port.

Impact Limiters

The HI-STAR 100 overpack is fitted with two standard impact limiters fabricated of aluminum honeycomb completely enclosed by an all-welded austenitic stainless steel skin. The two impact limiters are attached to the overpack with 20 and 16 bolts at the top and bottom, respectively. The HI-STAR HB and HB GTCC packages are fitted with slightly longer impact limiters, designated as HB impact limiters, incorporating a customized material crush strength.
