Stowage on Aircraft or Storage Incident to Transportation

AFMAN 24-204(I)/TM 38-250/NAVSUP PUB 505/MCO P4030.19H/ DLAI 4145.3 41 11 DECEMBER 2001 - Unless otherwise required, the shipper is exempt from maintaining the documentation required in the bullets above if that documentation is maintained by the Inventory Control Point (national stock number managing activity). - The documentation requirements specified in the bullets above do not apply in those cases where A₁ equals ^A2 and the material is not described on the shipping papers as "Radioactive Material, Special Form, N.O.S." A3.3.7.6. Stowage on Aircraft or Storage Incident to Transportation. - Do not ship radioactive yellow II or radioactive yellow III material on the same aircraft or store in any one area, such as a transit area, terminal building, storeroom, or assembly yard, if the sum of the transport indexes in any individual group of packages exceeds 50. - If the total transport index for all packages exceeds 50, separate the packages into groups. Store groups of these packages so as to maintain a spacing of at least 6 meters (20 feet) from other groups of packages containing radioactive materials. - Ensure separation of yellow II or yellow III material from packages containing undeveloped film according to the distances shown in 49 CFR 175.703. A3.3.7.7. Uranium Hexafluoride (Fissile and Low Specific Activity). In addition to any other applicable requirements of attachment 3 and attachment 11, package uranium hexafluoride, fissile or low specific activity, according to the following requirements: - Before initial filling and during periodic inspection and test, clean packages according to American National Standard N14.1. - Design, fabricate, inspect, test, and mark packagings according to American National Standard N14.1 in effect at the time the packaging was manufactured. - Ensure uranium hexafluoride is in solid form when offered for transportation. - The volume of the solid uranium hexafluoride at 20 degrees C (68 degrees F) must not exceed 61 percent of the volumetric capacity of the package. - Ensure the pressure in the package at 20 degrees C (68 degrees F) is less than 101.3kPa (14.8 psia). - Periodically inspect, test, and mark packages of uranium hexafluoride according to American National Standard N14.1-1987. - Perform each repair to a package of uranium hexafluoride according to American National Standard N14.1- 1987. A3.3.7.8. Specific Requirements for Fissile Shipments. - Fissile material packaging must meet the test requirements of 10 CFR Part 71. - Mixing fissile material packages with other types of radioactive materials, including fissile class I with fissile class II packages is authorized if the total transport index is not over 50. - See attachment 24 for Fissile Class III shipments. A3.3.7.9. Fissile Materials--Exceptions. The requirements of A3.3.7.8 do not apply to: - A package not containing more than 15 grams of fissile radionuclides. - A package containing irradiated natural or depleted uranium including the products of irradiation if the irradiation has taken place only in the thermal reactor. - A package containing homogeneous solutions or mixtures where: - The minimum ratio of the number of hydrogen atoms to the number of atoms of fissile radionuclides (H/X) is 5200. - The maximum concentration of fissile radionuclides is 5 grams per liter (g/l). - The maximum mass of fissile radionuclides in the package is 500 grams, except that for a mixture where the total mass of plutonium and uranium²³³ is not over 1 percent of the mass of uranium²³⁵, the limit is 800 grams. - A package containing uranium enriched in uranium²³⁵ to a maximum of 1 percent by weight, and with a total plutonium and uranium²³³content of up to 1 percent of the mass of uranium²³⁵, if the fissile radionuclides are distributed homogeneously throughout the package contents, and do not form a lattice arrangement within the package.
