CH-TRAMPAC Document Rev. 2, May 20053.3.1 Requirements3.3 Activity LimitsThe TRUPACT-II and HalfPACT are limited to a maximum total activity of 406 curies (Ci)when packaging payloads of either S100 or S300 pipe overpacks. The S100 and S300 pipeoverpack payloads are limited to sealed neutron sources in the forms specified in Table 3.3-1.Each payload shall be acceptable for shipment only if the determined activity plus the error (i.e.,one standard deviation) meets this limit.Table 3.3-1 – Sealed Source Forms for S100 and S300 Pipe Overpacks241 Am Be238 Pu Be239 Pu Be241 Am O238 Pu O239 Pu O244 Cm O241 Am Li239 Pu Li238 Pu B239 Pu F238 Pu 13 C241 Am238 Pu239 Pu244 CmThe contents of each S200 pipe overpack are limited to the radionuclides and associatedactivities listed in Table 3.3-2 for both the S200-A and S200-B shield insert configurations.Each S200 pipe overpack shall be acceptable for shipment only if the determined activity plusthe error (i.e., one standard deviation) meets the applicable limit.No activity limits exist for 55-gallon drums, standard pipe overpacks, 85-gallon drums,100-gallon drums, SWBs, or TDOPs.3.3.2 Methods of Compliance and VerificationCompliance with the activity requirements is similar to the compliance methodology describedin Section 3.1.2.The total activity plus the error (i.e., one standard deviation) for a payload of S100 or S300 pipeoverpacks shall be calculated and compared to the limit (406 Ci).For each S200 pipe overpack, the sum of “partial fractions” for any combination of radionuclidespresent in the waste must be less than or equal to one. The limits for individual radionuclides arespecified in Table 3.3-2.No activity limits exist for 55-gallon drums, standard pipe overpacks, 85-gallon drums,100-gallon drums, SWBs, or TDOPs.3.3-1
