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 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 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] .

2024年8月28日 · Because much of the nation’s HLW consists of spent nuclear fuel, the majority of HLW is stored on-site at nuclear power generating facilities (See also Locations of Independent Spent Fuel Storage Installations, U.S. NRC). There are two storage options for high-level waste: wet storage or dry storage.

On December 15, 2021, DOE signed the FRN affirming its interpretation of the statutory term “high-level radioactive waste.” The HLW interpretation is consistent with the law, the best available science and data, and the recommendations of the Blue Ribbon Commission on America’s Nuclear Future.

2023年5月24日 · 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.

High-level radioactive waste (HLW), which is the product of chemically reprocessing1 SNF, can be processed or unprocessed. The processing2 is used to produce a more stable HLW form that can be transported and eventually disposed of in a geologic repository.

2021年3月9日 · High-level waste. The highly radioactive materials produced as byproducts of fuel reprocessing or of the reactions that occur inside nuclear reactors. HLW includes: Irradiated spent nuclear fuel discharged from commercial nuclear power reactors

Only 5 grams of this is high-level waste – about the same weight as a sheet of paper. The generation of electricity from a typical 1,000-megawatt nuclear power station, which would supply the needs of more than a million people, produces only three cubic metres of vitrified high-level waste per year, if the used fuel is recycled.

High-level radioactive waste (HLW) is the highly radioactive material generated from reprocessing spent nuclear fuel (SNF). Starting in the 1940s, HLW resulted from reprocessing SNF to recover fissile material for use in nuclear weapons production.
