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, consistent with existing law, to require permanent ...
High-level waste is full of highly radioactive fission products, most of which are relatively short-lived. This is a concern since if the waste is stored, perhaps in deep geological storage, over many years the fission products decay, decreasing the radioactivity of the waste and making the plutonium easier to access.
The Nuclear Waste Policy Act of 1982 established a timetable and procedure for constructing a permanent, underground repository for high-level radioactive waste by the mid-1990s, and provided for some temporary storage of waste, including spent fuel from 104 civilian nuclear reactors that produce about 19.4% of electricity there.

The vitrification plant is planned to treat all the high-level radioactive waste in the tanks and much of the low activity waste. About 90% of the waste to be treated is low activity waste.
An infographic about the Yucca Mountain nuclear waste repository. Spent nuclear fuel is the radioactive by-product of electricity generation at commercial nuclear power plants, and high-level radioactive waste is the by-product of reprocessing spent fuel to produce fissile material for nuclear weapons.

Emptying of another leak-prone underground tank holding radioactive and other hazardous waste at the Hanford nuclear reservation has begun for the first time since August 2021.
Radioactive contamination, also called radiological pollution, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids, or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency (IAEA) definition).
Four melters are at the heart of the project to turn radioactive and chemical waste into glass. After 20+ years radioactive waste melting plant in Eastern WA takes key step forward Skip to main ...
