In this chapter,

(1) “atomic energy” means all forms of energy released in the course of nuclear fission or nuclear transformation;

(2) “by-product material” means radioactive material, except special nuclear material, yielded in or made radioactive by exposure to the radiation incident to the process of producing or utilizing special nuclear material;

(3) “nuclear fuel production facility” means a facility that purifies radioactive mineral concentrates and fabricates fissionable material to be used for producing energy in a nuclear reactor;

(4) “nuclear utilization facility” means an apparatus, device, or equipment in which nuclear fission is sustained in a self-supporting and controlled chain reaction; the term does not include an apparatus, device, or equipment used exclusively for educational, medical, or research purposes;

(5) “production facility” means equipment or a device capable of the production of special nuclear material in quantity of significance to the common defense and security, or to affect the health and safety of the public; or any important component part especially designed for the equipment or device;

(6) “radiation” means gamma rays and X-rays, alpha and beta particles, high-speed electrons, neutrons, protons, and other nuclear particles; but not sound or radio waves, or visible, infrared, or ultra-violet light;

(7) “special nuclear material” means plutonium, uranium 233, and uranium enriched in the isotope 233 or in the isotope 235, and any other material that the governor declares by order to be special nuclear material after the Nuclear Regulatory Commission has determined the material to be special nuclear material; or material artificially enriched by any of the foregoing material;

(8) “utilization facility” means equipment or a device, except an atomic weapon, capable of making use of special nuclear material in a quantity significant to the common defense and security, or in a manner affecting the health and safety of the public, or peculiarly adapted for making use of atomic energy in a quantity significant to the common defense and security, or in a manner affecting the health and safety of the public; or an important component part especially designed for the equipment or device.
