The Model 60 is a Fissile Class II shipping container designed for transporting FTR driver fuel pins. The design consists of an 18 x 18 x 112.5-inch metal birdcage with a centrally mounted 6-inch ID x 102.5-inch long containment vessel. The criticality safety evaluation shows that each container may be loaded with up to 120 FTR type fuel pins enriched to 31 wt% PuO₂-U(Nat)O₂ (6.75 kg Pu); and that a single Fissile Class II shipment may consist of up to 12 containers (1440 fuel pins). The Transport Index is 4.0.
