The TRUPACT-2 shipping package was designed to transport either standard waste boxes or 55-gal drums containing contact-handled transuranic waste to the Waste Isolation Pilot Plant. With the licensed payload, the TRUPACT-2 package complies with the requirements of 10CFR71.55 and -71.57 for a fissile Class 1 package (a package that may be transmitted in unlimited numbers and in any arrangement and that requires no criticality safety controls during transportation). The basis on which this classification is established is presented in this paper. Calculations with postaccident geometries and optimized reflector and moderator configurations were used to envelop both normal and accident conditions required by the NRC for a fissile Class 1 license. With 325 FGE of {sup 239}Pu per package, the TRUPACT-2 complies with the requirements of 10CFR71.55 and -71.57 for a fissile Class 1 package.
