Fissile material definition

Fissile material means the radionuclides uranium-233, uranium-235, plutonium-239, and plutonium-241, or any combination of these radionuclides. "Fissile material" means the fissile nuclides themselves, not material containing fissile nuclides. Unirradiated natural uranium and depleted uranium and natural uranium or depleted uranium, that has been irradiated in thermal reactors only, are not included in this definition. Certain exclusions from fissile material controls are provided in 10 CFR 71.15.
Fissile material means plutonium−238, pluto- nium−239, plutonium−241, uranium−233, uranium−235 or any combination of these radionuclides. Unirradiated natural ura- nium and depleted uranium, and natural uranium or depleted ura- nium that has been irradiated in thermal reactors only are not included in this definition.
Fissile material means the radionuclides uranium-233, uranium-235, plutonium-239, and plutonium-241, or any combination of these radionuclides. Fissile material means the fissile nuclides

Fissile material means fissile plutonium, uranium-233, and uranium-235 in any combination sufficient to cause (gm Pu/200 gm) + (gm U-233/200 gm) + (gm U-235 contained in uranium enriched to more than 20 percent in U-235)/350gm) to be greater than unity.¶
Fissile material means any special nuclear material consisting of or containing one or more fis- sile radionuclides. Fissile radionuclides are plutonium-238, plutonium-239, plutonium-241, ura- nium-233, and uranium-235. Neither natural nor depleted uranium is fissile material. Agency juris- diction extends only to special nuclear material if quantities are not sufficient to form a critical mass as defined in 641—Chapter 38.
