High-level waste - Wikipedia
High-level waste is the highly radioactive waste 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 other highly radioactive material that is determined ...
High-Level Waste | NRC.gov
2020年3月12日 · High-level radioactive wastes are the highly radioactive materials produced as a byproduct of the reactions that occur inside nuclear reactors. High-level wastes take one of two forms: Spent (used) reactor fuel when it is accepted for disposal; Waste materials remaining after spent fuel is reprocessed; Spent nuclear fuel is used fuel from a ...
High-level radioactive waste management - Wikipedia
High-level radioactive waste management addresses the handling of radioactive materials generated from nuclear power production and nuclear weapons manufacture. Radioactive waste contains both short-lived and long-lived radionuclides, as well as non-radioactive nuclides. [1] .
Backgrounder on Radioactive Waste | NRC.gov
High-Level Waste. High-level radioactive waste primarily is uranium fuel that has been used in a nuclear power reactor and is "spent," or no longer efficient in producing electricity. Spent fuel is thermally hot as well as highly radioactive and requires remote handling and shielding.
The disposal of high-level radioactive waste - Nuclear Energy …
What is high-level radioactive waste? The term high-level radioactive waste (HLW) generally refers to the highly radioactive wastes requiring permanent isolation from man's environment that arise as a byproduct of nuclear power generation.
Nuclear Waste Disposal | U.S. GAO
There are three main types of nuclear waste—high-level, transuranic, and low-level waste—and each type must be disposed of according to its risk to human health and the environment. For instance, high-level nuclear waste remains highly radioactive for tens of thousands of years and must be disposed of in such a way that it can be securely ...
The term high-level waste, generally implies the raffinate (liquid effluent) from the first cycle of fuel reprocessing operations that recover the plutonium and unburned uranium. The term also is extended to any matrix that contains a high enough concentration of fission

2024年2月14日 · High-level waste: High-level waste includes used nuclear fuel from nuclear reactors and waste generated from the reprocessing of spent nuclear fuel. Although defense-related activities generate most of the United States’ liquid high-level waste, the majority of spent nuclear fuel is from commercial nuclear power plant reactors.
Spent Nuclear Fuel and High-Level Radioactive Waste Disposal: The Goal Deep geologic disposal has been planned since the 1950s “There has been, for decades, a worldwide consensus in the nuclear technical community for disposal through geological isolation of high-level waste (HLW), including spent nuclear fuel (SNF).” “Geological disposal
