A11.8.1.8. DOT 20PF-1, 20PF-2, 20PF-3 or 21PF-1A, 21PF-1B, or 21PF-2 phenolic-foam insulated overpacks with
snug fitting inner metal cylinders meeting all of the applicable requirements of A3.1, A3.3.7.1, A3.3.7.2, A11.18 and
the following:
-
Handling procedures and packaging criteria must comply with US Department of Energy Report Number
ORO-651 or ANSI N14.1.
-
Quantities of uranium hexafluoride are authorized as shown in table A11.6, with each package assigned a
minimum transport index as also shown.
A11.8.2. Package fissile radioactive materials with radioactive content over A1 or A2 in either:
A11.8.2.1. DOT 6L Metal Packaging.
-
Authorized only for uranium-235, plutonium-239, or plutonium-241, as metal oxide, or compounds that do
not decompose at temperatures up to 149 degrees C (300 degrees F).
-
Radioactive decay heat output must not be more than 5 watts.
-
Radioactive materials in normal form must be packaged in one or more tightly-sealed metal cans or
polyethylene bottles within a DOT 2R containment vessel.
-
Authorized contents are limited per table A11.4:
