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 ...
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 US currently defines five types of radioactive waste, as shown below. High-level Waste: This type of radioactive waste is generated from nuclear reactors or reprocessing spent nuclear fuel. [15] Transuranic Waste: This type of radioactive waste is man-made and has an atomic number of 92 or higher. [15]
The Hanford site represents two-thirds of the United States' high-level radioactive waste by volume. Nuclear reactors line the riverbank at the Hanford Site along the Columbia River in January 1960. As of 2013, the Fukushima nuclear disaster site remains highly radioactive , with some 160,000 evacuees still living in temporary housing, and some ...
Deep borehole disposal (DBD) is the concept of disposing high-level radioactive waste from nuclear reactors in extremely deep boreholes instead of in more traditional deep geological repositories that are excavated like mines. Deep borehole disposal seeks to place the waste as much as five kilometres (3 mi) beneath the surface of the Earth and ...
