<strong>RH</strong>-<strong>TRAMPAC</strong> Document Rev. 0, June 20063.0 NUCLEAR PROPERTIES REQUIREMENTS3.1 Nuclear CriticalityThe nuclear properties requirements outlined in this section require a knowledge <strong>of</strong> isotopiccomposition and quantity <strong>of</strong> fissile material. Requirements as per 10 CFR §71.55 and §71.59 1are summarized for the <strong>RH</strong>-TRU 72-B payload. Detailed discussions <strong>of</strong> these requirements areprovided in Section 6.0 <strong>of</strong> the <strong>RH</strong>-TRU 72-B SAR 2 .3.1.1 RequirementsAn <strong>RH</strong>-TRU canister is acceptable for transport only if the fissile content is less than or equal toone <strong>of</strong> the following plutonium (Pu)-239 fissile grams equivalent (FGE) or uranium (U)-235fissile equivalent mass (FEM) limits:Pu-239 Fissile Grams Equivalent LimitsNo Credit for Pu-240 PoisoningAn <strong>RH</strong>-TRU canister shall be acceptable for transport only if the Pu-239 FGE plus twotimes the error (i.e., two standard deviations) is less than or equal to the following limits:• 315 FGE for an <strong>RH</strong>-TRU canister, except for <strong>RH</strong>-TRU canisters containing greaterthan 1% by weight beryllium (Be) or beryllium oxide (BeO) or machine-compactedwaste• 305 FGE for an <strong>RH</strong>-TRU canister containing greater than 1% by weight Be or BeOthat is chemically or mechanically bound to the fissile material• 100 FGE for an <strong>RH</strong>-TRU canister containing greater than 1% by weight Be or BeOthat is not chemically or mechanically bound to the fissile material• 245 FGE for an <strong>RH</strong>-TRU canister containing machine-compacted waste• <strong>RH</strong>-TRU canisters containing greater than 1% by weight Be or BeO and machinecompactedwaste are not shippable.Credit for Pu-240 Poisoning• For <strong>RH</strong>-TRU canisters without machine-compacted waste containing less than orequal to 1% by weight Be or BeO, the limits in Table 3.1-1 apply. The minimumPu-240 content for the <strong>RH</strong>-TRU canister shall be determined after the subtraction <strong>of</strong>two times the error.1 Title 10, Code <strong>of</strong> Federal Regulations, Part 71 (10 CFR 71), Packaging and Transportation <strong>of</strong> RadioactiveMaterial, Final Rule, 01-26-04.2 U.S. <strong>Department</strong> <strong>of</strong> Energy (DOE), <strong>RH</strong>-TRU 72-B Safety Analysis Report, current revision, U.S. <strong>Department</strong> <strong>of</strong>Energy, Carlsbad Field Office, Carlsbad, New Mexico.3.1-1
