A11.8.2.2. DOT 6M Metal Packaging. Authorized only for solid radioactive materials that do not decompose at
temperatures up to 121 degrees C (250 degrees F). Radioactive decay heat output must not exceed 10 watts.
Radioactive materials in other than special form must be packaged in one or more tightly-sealed metal cans or
polyethylene bottles within a DOT specification 2R containment vessel.
-
Limit packages of fissile material with a criticality TI equal to 0.0 to 1.6 kg of uranium 235; 0.9 kg of
plutonium (except that due to the 10-watt thermal decay heat limitation, the limit for plutonium-238
is 0.02
kg); and 0.5 kg of uranium-233. The maximum ratio of hydrogen to fissile material must not be greater
than three, including all of the sources of hydrogen within the DOT 2R containment vessel.
-
Use table A11.5 to determine maximum quantities of fissile material and other restrictions for materials
with a criticality TI if greater than 0.0. The minimum transport index to be assigned per package and, for
fissile material, controlled shipments, the allowable number of similar packages per transport vehicle is
shown in table A11.5. Where a maximum ratio of hydrogen to fissile material is specified in table A11.5,
only the hydrogen interspersed with the fissile material has to be considered. For a uranium-233
shipment,
the maximum inside diameter of the inner containment vessel must not be over 12.1 cm (4.75 inches).
Where necessary, use a tight-fitting steel insert to reduce a larger diameter inner containment vessel
specified in 49 CFR 178.354 to the 12 centimeters (4.75 inches) limit.
