Section 333-118-0053 - General Regulatory Provisions: Exemption from Classification as Fissile Material

Fissile material meeting the requirements of at least one section of this rule are exempt from classification as fissile material and from the fissile material package standards of 10 CFR Parts 71.55 and 71.59, but are subject to all other requirements of this rule, except as noted.

(1) Individual package containing two grams or less fissile material.

(2) Individual or bulk packaging containing 15 grams or less of fissile material provided the package has at least 200 grams of solid nonfissile material for every gram of fissile material. Lead, beryllium, graphite, and hydrogenous material enriched in deuterium may be present in the package but must not be included in determining the required mass for solid nonfissile material.

(3) Low concentrations of solid fissile material commingled with solid nonfissile material, provided that:

(a) There is at least 2000 grams of solid nonfissile material for every gram of fissile material; and

(b) There is no more than 180 grams of fissile material distributed within 360 kg of contiguous nonfissile material.

(4) Lead, beryllium, graphite, and hydrogenous material enriched in deuterium may be present in the package but must not be included in determining the required mass of solid nonfissile material.

(5) Uranium enriched in uranium-235 to a maximum of one percent by weight, and with total plutonium and uranium-233 content of up to one percent of the mass of uranium-235, provided that the mass of any beryllium, graphite, and hydrogenous material enriched in deuterium constitutes less than five percent of the uranium mass and the fissile material is distributed homogeneously and does not form a lattice arrangement within the package.

(6) Liquid solutions of uranyl nitrate enriched in uranium-235 to a maximum of two percent by mass, with a total plutonium and uranium-233 content not exceeding 0.002 percent of the mass of uranium, and with a minimum nitrogen to uranium atomic ratio (N/U) of two. The material must be contained in at least a DOT Type A package.

(7) Packages containing, individually, a total plutonium mass of not more than 1000 grams, of which not more than 20 percent by mass may consist of plutonium-239, plutonium-241, or any combination of these radionuclides.
