CH-TRAMPAC Document Rev. 2, May 20056.0 PAYLOAD ASSEMBLY REQUIREMENTSThis chapter presents an overview of the control procedures that shall be used by the sites inorder to assemble a payload qualified for transport in the TRUPACT-II or the HalfPACT. Theparameters described in previous chapters shall be evaluated for selection of a payload. Theevaluation of transportation compliance for a payload container is shown in Figure 6.1-1. Thecontainer identification (ID) number shall uniquely identify the payload container. Each payloadcontainer shall have an assigned shipping category and content code. Wherever applicable, thephysical, nuclear, and gas generation measured parameters (weight, fissile material, decay heat,and flammable gas generation rate) shall be checked against the limits after addition of themeasurement error, as detailed in previous chapters. If any of the physical, chemical, or nuclearproperty limits are not met by the container, it shall be rejected from transport (subject tomitigation or repackaging), marked, and segregated. Containers that do not meet individualcontainer gas generation limits (decay heat, flammable gas generation rate, total gas generationrate, etc.) may still meet transportation requirements if mixed with other payload containers ordunnage containers during payload assembly, in accordance with Sections 6.2.4 and/or 6.2.5.Assembled payloads shall comply with the authorized payload configurations specified inSection 2.1. A TRUPACT-II or HalfPACT payload may be assembled of payload containersbelonging to the same shipping category or different shipping categories (e.g., payload mayconsist of several shipping categories and/or may take credit for void volume provided bydunnage containers). The logic for selecting a payload qualified for transport when all payloadcontainers belong to the same shipping category is presented in Figure 6.1-2. Payload selectionshall be made from only those payload containers that have been approved for payload assembly.6.1 RequirementsOnce compliance with all transportation parameter requirements is verified and the appropriatePCTCD(s) and/or OPCTCD(s) is completed, the TRUPACT-II or HalfPACT package shall beauthorized for shipment by the site Transportation Certification Official by completing andsigning the PATCD.Payload assembly requirements specific to Content Code LA 154 and SQ 154 payloads, whichsupplement the requirements of this section, are specified in Appendix 6.12 of the CH-TRUPayload Appendices. 1The shipping records shall be maintained by the shipper for a minimum period of 3 years.1 U.S. Department of Energy (DOE), CH-TRU Payload Appendices, U.S. Department of Energy, Carlsbad FieldOffice, Carlsbad, New Mexico.6.1-1
