Definitions for "High-level waste"
As defined by the Nuclear Waste Policy Act, high-level waste is (1) the highly radioactive material resulting from the reprocessing of spent nuclear fuel, including the 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 U.S. Nuclear Regulatory Commission, consistent with existing law, determines by rule to require permanent isolation.
(HLW)— radioactive waste material derived from the first cycle of solvent extraction from processing of irradiated fuel, or equivalent material from other parts of the processing operations, and spent nuclear fuel (from 10 CFR 50).
