Natural uranium contains approx 0.7 percent U235, the rest U238. The 235 is the useful fissile isotope. Some reactors using graphite or heavy water can use natural uranium, but light water reactors need to have the U235 proportion increased to about 4 percent. this is called enrichment.
What else can I help you with?
Engineers increase the concentration of uranium-235 atoms in nuclear fuel during what process?
Enrichment
Can nuclear power plants make nuclear weapons?
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.
Which area of technology is associated with nuclear energy?
Nuclear physics, fuel enrichment and fabrication, metallurgy, welding, instrumentation, chemistry, radiation measuring, and civil, electrical, and mechanical engineering, to name a few, are areas of technology associated with nuclear energy.
Are centrifuges used to make nuclear weapons?
Centrifuges are one method of enriching Uranium. Depending on how much you enrich it the Uranium can be usable as either reactor fuel or nuclear weapon explosive.Other methods of enrichment include:gaseous diffusioncalutronsthermal diffusion
What pollution is produced in nuclear power stations?
Nuclear power stations produce nuclear waste. This waste can be radioactive and pose risks to human health and the environment if not properly managed and disposed of. Additionally, some emissions of carbon dioxide and other pollutants can be produced during the mining, milling, and enrichment of the fuel used in nuclear power plants.
Engineers increase the concentration of uranium-235 atoms in nuclear fuel during what process?
Enrichment
Is fuel enrichment done for thorium?
No, Thorium is a fertile nuclear material.
What radioactive isotope is generally used to fuel a controlled nuclear chain reaction?
Uranium-235 is the main radioactive isotope used to fuel controlled nuclear chain reactions in nuclear reactors. It undergoes fission when bombarded with neutrons, releasing energy and more neutrons to sustain the chain reaction.
What is the element mined to be the fuel in nuclear reactors?
We mine uranium for use as a nuclear fuel. The uranium is separated from ore, and may undergo enrichment to separate out the lighter U-235 nuclide from the heavier U-238 one.
Is nuclear fuel imported?
Assuming you mean to the US, I think most of the raw uranium is now imported, from Australia and Canada mainly, but the enrichment and fuel assembly manufacture is in the US.
What is UF4?
UF4 is uranium tetrafluoride. It is a solid compound that is used in the production of nuclear fuel and nuclear weapons. UF4 is also a precursor in the conversion of uranium to uranium hexafluoride (UF6) for enrichment purposes.

What mineral is used in nuclear power?
Uranium is the primary mineral used in nuclear power plants as a fuel source for nuclear fission reactions. It undergoes a process of enrichment to increase the concentration of the Uranium-235 isotope, which is the type of uranium that undergoes fission in nuclear reactors.
How much uranium is need to power a nuclear power plant for eighteen months?
On average, a nuclear power plant requires about 27 metric tons of uranium (in the form of enriched uranium fuel) to operate for 18 months. This amount may vary depending on the specific reactor design and power output of the plant.
How much plutonium is in 1 ton of nuclear waste?
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.
Can nuclear power plants make nuclear weapons?
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.
What kind of nuclear work does North Korea work on?
Uranium enrichment.
