Department of Transportation (DOT) in 49 CFR Part 173 and whose use is imited by the ierms and conditions of the specification and provisions in 49 CFR Part 178. DOT Specification con- tainers are authorized for use by NRC licensees by general license provisions in 10 CFR Part 71. Empty cylinder: A cylinder containing a residual amount of UFe and nonvolatile reaction products of uranlum (heel) In quantitles less than those specified In 8.1.2. This definltion should noi be conlusedi wilh the caiegory of empiy packaging used in 49 CFR 173.428. 3.7 Fabricator: One who manufactures, repairs, or modifies a packaging. Fissile materia!: UF containing uranium that has more uranium-235 than the naturally occurring distribution ot uranium isotopes. Note : UFe that is tissile material but is enriched to a maximum of one welght percent U-235, or Is lmited to a maximum 15 grams of fislle radlonu- clides (U-233, U-235, Pu-238, Pu239, and Pu-241) per package is coIsidered fssile excepled material.
3.9 Fissile excepted material: UFo containing uranium that is enriched to a maximum of 1 weight percent U-235, with a tota! plutonium and uranium-233 content up to 1 percent of the mass of uranlum-235, or UFε that is limited to a maximum of 15 grams of fssle radionuclides (U- 233, U-235, Pu-238, Pu-239, and Pu-241) per package..
3.10 Heel: A residual amount of UFg and nonvolatile reaction products of uranium. 3.11 Low- specific- activity material: Uniradiated UFo that is classified as non-fissile or fissile excepted material.
3.12 MDMT: Minimum design metal temperature to meet ASME Code requirements.
3.13 MAWP: Maximum alowable working pressure permitted by ASME Code requirements.
3.14 New cylinder: An unused cylinder that has been cleaned to remove fabrication debris.
3.15 Non-fissile materia!: Unirradiated UF。composed of natura! or depleted uranium.
3.16 Normal-form radioactive materlal: A radioactive material that has not been demonstrated to qualifly as special-form radioactive material. UFε is classified as a normal-form material.
3.17 Owner: The individual, agency, contractor, company, or corporation that carries title to, or will carry title to, the packaging during its use.
3.18 Packaging: A container to be used tor the transport ot UFs, including the outer protective packaging when uilized.
3.19 Outer protective packaging (overpack): Outer packaging used for fire and impact protection for cylinders containing fisile UF&.
3.20 Qualifiod inspector: An individual who has passed the witten examination sponsored by the National Board of Boiler and Pressure Vessel Inspectors, and holds a current certiticate of competency, or other competent inspector designated by the cylinder owner’s inspection authority.
3.21 Shall, should, and may: The word“shall” denotes a requiromont, the word“should” de notos a recommendation, and the word “may” denotes permission, neither a requirement nor a recommendation. Contormance with this standard means that all operations are pertormed in accordance with its requirements but not necessarily with its recommendations.
3.22 Shipper: One who offers the package of UFs for transport.
3.23 Transport index: (for domcstic shipmcnts in thc Unitcd Statcs to mcct DOT rcquirc ments). The dimensionless number (rounded up to the next tenth) placed on the label of a pack- age to designate the degree of control to be exercised by the carrier during transportation. The transport index is determined as foilows:
