Chapter 2.7 – Radioactive material

Parent topic: Part 2 – Classification

2.7.1.3 Definitions or specific terms

  Fissile material The paragraph before subparagraphs .1 and .2 is replaced with the following:

  • "Fissile nuclides means uranium-233, uranium-235, plutonium-239 and plutonium-241. Fissile material means a material containing any of the fissile nuclides. Excluded from the definition of fissile material are:"

Classification as "fissile-excepted" is allowed only if one of the conditions (a) to (d) of this paragraph is met. Only one type of exception is allowed per consignment (see also 6.4.7.2).".

  2.7.2.3.5.1 Replace by the following:

    where X and Y are the mass limits defined in Table 2.7.2.3.5, provided that either:

    • (i) each individual package contains not more than 15 g of fissile nuclides; for unpackaged material, this quantity limitation shall apply to the consignment being carried in or on the conveyance; or

    • (ii) the fissile material is a homogeneous hydrogenous solution or mixture where the ratio of fissile nuclides to hydrogen is less than 5% by mass; or

    • (iii) there are not more than 5 g of fissile nuclides in any 10 litre volume of material.

    Beryllium shall not be present in quantities exceeding 1% of the applicable consignment mass limits provided in Table 2.7.2.3.5 except where the concentration of beryllium in the material does not exceed 1 gram beryllium in any 1000 grams.

    Deuterium shall also not be present in quantities exceeding 1% of the applicable consignment mass limits provided in Table 2.7.2.3.5 except where deuterium occurs up to natural concentration in hydrogen.".

  2.7.2.3.5.2 Replace "fissile material is" with "fissile nuclides are".

  2.7.2.3.5.4 The paragraph is replaced by the following:

  • “.4 Plutonium containing not more than 20% of fissile nuclides by mass up to a maximum of 1 kg of plutonium per consignment. Shipments under this exception shall be under exclusive use.".
