71.22—General license: Fissile material.
(a)
A general license is issued to any licensee of the Commission to transport fissile material, or to deliver fissile material to a carrier for transport, if the material is shipped in accordance with this section. The fissile material need not be contained in a package which meets the standards of subparts E and F of this part; however, the material must be contained in a Type A package. The Type A package must also meet the DOT requirements of 49 CFR 173.417(a).
(b)
The general license applies only to a licensee who has a quality assurance program approved by the Commission as satisfying the provisions of subpart H of this part.
(2)
Contain less than 500 total grams of beryllium, graphite, or hydrogenous material enriched in deuterium.
(d)
The general license applies only to packages containing fissile material that are labeled with a CSI which:
(3)
For a shipment of multiple packages containing fissile material, the sum of the CSIs must be less than or equal to 50 (for shipment on a nonexclusive use conveyance) and less than or equal to 100 (for shipment on an exclusive use conveyance).
(e)
(1)
The value for the CSI must be greater than or equal to the number calculated by the following equation:
(3)
The values of X, Y, and Z used in the CSI equation must be taken from Tables 71-1 or 71-2, as appropriate;
(4)
If Table 71-2 is used to obtain the value of X, then the values for the terms in the equation for uranium-233 and plutonium must be assumed to be zero; and
(iii)
The uranium is of unknown uranium-235 enrichment or greater than 24 weight percent enrichment; or
(iv)
Substances having a moderating effectiveness (i.e., an average hydrogen density greater than H2 O) (e.g., certain hydrocarbon oils or plastics) are present in any form, except as polyethylene used for packing or wrapping.
| Fissile material | Fissile material mass mixed with moderating substances having an average hydrogen density less than or equal to H2O (grams) | Fissile material mass mixed with moderating substances having an average hydrogen density greater than H2Oa (grams) |
|---|---|---|
| 235 U (X) | 60 | 38 |
| 233 U (Y) | 43 | 27 |
| 239 Pu or 241 Pu (Z) | 37 | 24 |
| a When mixtures of moderating substances are present, the lower mass limits shall be used if more than 15 percent of the moderating substance has an average hydrogen density greater than H2O. | ||
