Under nuclear fission with thermal neutrons uranium release an enormous quantity of energy (202,5 MeV per one atom of 235U); the obtained heat is converted in electricity.
And we need electricity and heat. also uranium is an alternative to fossil fuels; nuclear reactors don't contribute to global warming and don't release carbon dioxide.
What else can I help you with?
What fuel does a nuclear reactor use?
Uranium-235 in combination with Uranium-238, enriched from natural levels of about 0.7% U-235 to about 5% U-235. There are other configurations, but this is the most common.
Why must uranium be enriched before it can be used as a fuel source in a nuclear reactor?
Uranium must be enriched to increase the concentration of uranium-235 isotope, which is the isotope that undergoes fission in nuclear reactors. Natural uranium primarily consists of uranium-238, which is not as efficient at sustaining a nuclear chain reaction. Enrichment increases the proportion of uranium-235, making the fuel more suitable for use in reactors.
What is a use for Uranium fuel?
Uranium fuel is primarily used in nuclear reactors to generate electricity through the process of nuclear fission. It is a highly efficient and low-carbon energy source that can produce large amounts of power from a small amount of fuel. Additionally, uranium fuel can also be used in the production of medical isotopes and for certain research purposes.
What type of reactions or fuel did the Chernobyl nuclear plant use?
The Chernobyl nuclear plant used enriched uranium as fuel in its reactor. The accident at the plant resulted in a nuclear chain reaction, leading to a catastrophic explosion and release of radioactive materials.
What element is put into nuclear reactors for energy?
Reactors can be fueled by uranium or many of the transuranic elements, but uranium is the only element that occurs naturally with large enough levels of its fissionable isotope uranium-235 for practical use. Plutonium is also a good reactor fuel, but must be produced first from the plentiful but nonfissionable uranium-238 in a reactor as it only occurs naturally at trace levels. While thorium cannot be directly used as fuel, the fissionable isotope uraniuum-233 which can be used as fuel can be produced from it in a nuclear reactor. For transuranics other than plutonium (and maybe americium) specially designed fast neutron reactors are required to effectively use them as fuel, but they too can be used.
What fuel does a nuclear reactor use?

Why do you use uranium and plutonium in the reactor?
Uranium and plutonium are used in reactors because they are fissile materials that can undergo nuclear fission, releasing a large amount of energy. This energy is harnessed to generate electricity in nuclear power plants.
What is a way to produce heat energy?
Burn a fossil fuel like coal or oil, or use uranium in a nuclear reactor
Is uranium safe to use?
Depending of the use, depending of the chemical and physical form, the protective precautions applied, quantity, if it is irradiated in a nuclear reactor or not, etc.
How does one use a breeder reactor?
It would be used as a more efficient version of a Nuclear Reactor. While a regular nuclear reactor requires almost a factor of 100 greater in fuel amounts, a Breeder reactor uses much less and produces less waste.
Why must uranium be enriched before it can be used as a fuel source in a nuclear reactor?
Uranium must be enriched to increase the concentration of uranium-235 isotope, which is the isotope that undergoes fission in nuclear reactors. Natural uranium primarily consists of uranium-238, which is not as efficient at sustaining a nuclear chain reaction. Enrichment increases the proportion of uranium-235, making the fuel more suitable for use in reactors.
How does the uranium used in a CANDU reactor exist in nature?
The uranium used in a CANDU reactor primarily exists as uranium-238, a naturally occurring isotope found in various minerals, with a small percentage of uranium-235. It is extracted from uranium ore through milling and chemical processes to increase the concentration of uranium-235 for use as nuclear fuel in reactors.
What fuel is used in nuclear power plants?
A nuclear reactor is a device to initiate, control, and sustain a nuclear chain reaction. Nuclear power is energy produced from controlled nuclear reactions. When it comes to just standard fuel across the table it would have to be: Plutonium, Uranium, and Thorium.
Can a nuclear reactor be used as a nuclear weapon?
No. LLNL even tested several Uranium-Hydride bombs in the 1950s. Even though their computer models said the devices should explode, none gave a nuclear yield. One could use the waste from the reactor as a Radiological Weapon, but the reactor itself is not useful as a weapon.
Does the government use uranium?
Yes, the government uses uranium. Uranium is mined, refined and then enriched to provide nuclear fuel for nuclear reactors. Depleted uranium, the uranium "left over" from enrichment, is used in munitions to defeat armor, and in some types of armor. On a related note, enriched uranium is in demand by some sovern states and religeous/political factions to make nuclear weapons, though the "modern" nuclear powers use plutonium as the fissionable element in their nuclear devices. The plutonium is made by "soaking" uranium in the neutron flux of an operating nuclear reactor for a time. This changes (transmutes) some of the uranium to plutonium, which is then recovered and processed.
An energy source that heats fuel rods is?
Nuclear energy is produced when fuel rods containing radioactive material such as uranium-235 are heated within a nuclear reactor. The heat generated from the fission of the uranium atoms is used to produce steam, which drives turbines to generate electricity.
Do Breeder reactor and nuclear reactor have similarities?
A breeder reactor is one type of nuclear reactor, but not a type that is in general commercial use at the present time
