Spent fuel pool
A spent fuel pool is a water-filled basin at a nuclear power plant where irradiated fuel assemblies removed from the reactor are stored underwater for cooling, shielding, and contamination control.
Spent nuclear fuel
Spent nuclear fuel is the intensely radioactive fuel removed from a nuclear reactor after it can no longer sustain a chain reaction, stored in pools and dry casks.
Uranium enrichment
Uranium enrichment is the physical process of increasing the proportion of the fissile isotope uranium-235 in uranium, most often to make fuel for nuclear reactors and weapons.
Uranium extraction from seawater
Uranium extraction from seawater (UES) recovers dissolved uranium from ocean water, which holds about 4.5 billion tons, mostly by adsorption onto amidoxime adsorbents, though costs still exceed terrestrial mining.
Uranium-233
Uranium-233 is a fissile artificial isotope of uranium with a half-life of about 160,000 years, bred from natural thorium-232 by neutron capture and used as a nuclear reactor fuel.
