Transport Vehicle

TM 55-315

by dividing 50 by the allowable number of packages that may be transported together, whichever is larger.

2-47. Transport Vehicle

A transport vehicle is the railcar, motor truck, trailer, or other highway vehicle used to transport radio-active material.

Aircraft and watercraft are not included.

2-48. Type A Package

A Type A package is a Type A packaging plus its limited radioactive contents. A Type A package does not require

competent authority approval, since its contents are limited to A1 or A2 quantities.

2-49. Type A Packaging

A Type A packaging is a packaging designed to retain the integrity of containment and shielding required under normal

transport conditions as shown by the tests set forth in Type A packaging tests (49 CFR 173.465) or in the additional tests

for Type A packagings designed for liquids and gases (49 CFR 173.466) as appropriate.

2-50. Type B Package

A Type B package is a Type B packaging plus its radioactive contents.

2-51. Type B Packaging

Type B packaging is a packaging designed to retain the integrity of containment and shielding required when subjected to

the normal conditions of transport and hypothetical accident test conditions set forth in 10 CFR 71.

2-52. Type B(M) Package

A Type B(M) package is a Type B packaging, plus its radioactive contents that, for international ship- ments, requires

multilateral approval of the package design and may require approval of the conditions of shipment. Type B(M)

packages are those Type B package designs that have a maximum normal operating pressure gauge with a range of

more than 7 kilograms per square centimeter (100 pounds per square inch) or a relief device that would allow the release

of radioactive material into the environment under the hypothetical accident conditions specified in 10 CFR 71.

2-53. Type B(U) Package

A Type B(U) package is a Type B packaging plus its radioactive contents that, for international shipments, requires

unilateral approval only of the package design and of any storage provisions that may be necessary for heat dissipation.

2-54. Types A and B Quantities

Types A and B quantities are the quantities of activity contained in Type A or B packages as outlined in chapters 3 and 4.

2-55. Uncompressed Gas

For this manual, uncompressed gas is gas at a pressure not exceeding the ambient atmospheric pressure at the time and

place the containment system is closed. All other radioactive gases are considered to be compressed.

2-56. Unilateral Approval

Unilateral approval is approval by the competent authority of the country of origin only.

2-57. Uniradiated Thorium

-7

Uniradiated thorium is thorium containing not more than 10 grams of uranium-233 per gram of thorium-232.

2-58. Uniradiated Uranium

Uniradiated uranium is uranium containing not more than 10-6 grams of plutonium per gram of uranium-235 and a fission

product activity of not more than 0.25 millicurie of fission products per gram of uranium-235.

2-59. Used Solely For Vehicles

Used solely for transport vehicles are vehicles that can be used by more than one consignor at one time. However, the

material being shipped must be identical on that and on each subsequent shipment.
