Spent nuclear fuel means fuel that has been withdrawn from a nuclear re- actor following irradiation, the con- stituent elements of which have not been separated by reprocessing. Any determination by theBoard under Article XX of the Statute of the Agency after the entry into force of this Protocol which adds to the materials considered to be source material or special fissionable material shall have effect under this Protocol only upon acceptance by. The term source material shall not be interpreted as applying to ore or ore residue. Nuclear material means any source or any special fissionable material as defined in Article XX of the Statute. Nuclear Hazard means any nuclear reaction, radiation, or radioactive contamination, all whether controlled or uncontrolled or however caused, or any consequence of any of these. Nuclear reactor means any apparatus designed or used to sustain nuclear fission in a self-supporting chain reaction or to contain a critical mass of fissionable material. Nuclear facility means (i) any nuclear reactor, (ii) any equipment or device designed or used for separating the isotopes of uranium or plutonium, processing or utilizing spent fuel, or handling, processing or packaging waste, (iii) any equipment or device used for the processing, fabricating or alloying of special nuclear material, if at any time the total amount of such material in the custody of an insured at the premises where such equipment or device is located consists of or contains more than 25 grams of plutonium or uranium 233 or any combination thereof, or more than 250 grams of uranium 235, or Nuclear energy hazard means the radioactive, toxic, explosive, or other hazardous properties of radioactive material Nuclear Fuel means any material which is capable of producing energy by a self-sustaining chain process of nuclear fission. Nuclear pharmacy means a pharmacy providing radiopharmaceutical services. Nuclear waste means a quantity of source, byproduct or special nuclear material required to be in NRC−approved speci- fication packaging while transported to, through or across a state boundary to a disposal site, or to a collection point for transport to a disposal site. Nuclear fission is another available option although there are concerns about its safety and the long-term issues of waste disposal. At-reactor (AR) spent fuel storage: activities related to the storage of spent fuel in at reactor spent fuel storage facilities (wet type) for an interim period.Nuclear fission takes place, with the release of energy To the latter one two main themes are proposed - Fusion energy research and Nuclear fission and radiation protection. Nuclear fission It is a nuclear change in which heavier nucleus split into lighter nuclei on bombardment of fast moving neutrons. Nuclear fission power appears to be the only technology able to offer higher power levels for long mission durations [Ref.Īrtificial radioactivity – radio isotopes – effects and Uses, Radio carbon dating – biological radiation hazards Nuclear fission and fusion, nuclear reactors, nuclear powered ships, nuclear hazards and precautions.
