  "term": "High-Level Radioactive Waste",
  "field": "Environment",
  "definition": "1. Waste generated in core fuel of a nuclear reactor, found at nuclear reactors or by nuclear fuel reprocessing; is a serious threat to anyone who comes near the waste without shielding.\n\n2. Radioactive material resulting from spent nuclear fuel reprocessing. Radioactive materials can be designated as high-level waste if they require permanent isolation. This determination is made by the U.S. Nuclear Regulatory Commission (NRC) based criteria established in U.S. law.\n\n3. The highly radioactive material resulting spent nuclear fuel reprocessing;(1)liquid waste directly produced in reprocessing (2)any solid material derived from the liquid wastes having a sufficient concentration of fission products. Other highly radioactive materials can be designated as high-level waste, if they require permanent isolation. This determination is made by the U.S. Nuclear Regulatory Commission based criteria established in U.S. law.\n\n4. Highly radioactive materials produced as a byproduct inside nuclear reactors. Other highly radioactive materials can be designated as high-level waste, if they require permanent isolation.\n\n5. Aqueous waste resulting from the operation of the first cycle solvent extraction system, or equivalent, and the concentrated waste from subsequent extraction cycles, or equivalent, in a facility for reprocessing irradiated reactor fuels or irradiated fuel from nuclear power reactors.\n\n6. As used in this part, means high-level radioactive waste as defined in the Nuclear Waste Policy Act of 1982 (Pub. L. 97-425).\n\n7. (1) The highly radioactive material resulting from the reprocessing of spent nuclear fuel, including liquid waste produced directly in reprocessing and any solid material derived from such liquid waste that contains fission products in sufficient concentrations; and (2) Other highly radioactive material that the Commission, consistent with existing law, determines by rule requires permanent isolation.",
