Yes, many reactors use uranium as their nuclear fuel, but some use plutonium or a uranium-plutonium mix.
Nuclear Fission.Generally Uranium, but some reactors use Plutonium nuclear fission.
After the nuclear fuel is spent the fuel is radioactive. This radiation causes decay heat. The result of the radiation causes movement of atoms, converting it into thermal energy.
Nuclear reactors are potentially dangerous and could not be allowed in vehicles on normal public roads
It can produce low grade plutonium that need be extracted from the used nuclear fuel through used fuel reprocessing. However, power reactors are subject to the international nuclear safeguards to prevent its misuse.
Irradiation of uranium in nuclear reactors, separation from the spent nuclear fuel, refining
No, they are stored in pools of water.
The amount of plutonium in the nuclear waste depends on the type of waste and its origin. If by waste, it is meant the spent nuclear fuel discharged from reactor after irradiation, then the plutonium amount depends mainly on the nuclear fuel initial enrichment, the neutron irradiation flux, and the time of irradiation.In usually operated nuclear power reactors of light water reactors, the discharged spent fuel contains roughly 1 kg plutonium per ton of fuel.
No substitute for nuclear power reactors especially if there is no available fossil fuel.
Uranium and/or Plutonium fuel
yes
Nuclear reactors.
Uranium is a radioactive element used to fuel nuclear reactors. It is a nuclear fuel.
In the US they're stored on site.
It is Uranium
Like any powerful bit of machinery, it CAN be. However, you might note that there has never been a fatality in the US from the Nuclear portion of a nuclear power reactor. Reactors do not create green house gasses, and they do not put the pollutants into the air that oil and coal fired powerplants do. Spent nuclear fuel remains radioactive and must be stored in a safe manner.
Uranium is not a fossil fuel; uranium is used as nuclear fuel for nuclear power reactors.
