Light water reactors use enriched fuel because natural uranium typically does not have a high enough concentration of the fissile isotope uranium-235 to sustain a nuclear chain reaction. Enrichment increases the proportion of uranium-235 in the fuel to enable sustained fission reactions.
What else can I help you with?
Enriched fuel pellets are used to make what?
Enriched fuel pellets are used to fuel nuclear reactors, particularly in nuclear power plants. These pellets consist of enriched uranium to sustain the nuclear fission process that generates heat to produce electricity.
Whats most commonly used fuel for nuclear reactors is?
The most commonly used fuel for nuclear reactors is enriched uranium, typically in the form of uranium-235. This fuel undergoes nuclear fission to produce heat energy, which is used to generate electricity. Different types of reactors and fuel cycles may also use other materials like plutonium or thorium.
What fuels are used in nuclear reactors?
Most reactors use uranium fuel enriched slightly to about 3-4 percent U-235, in the form of uranium dioxide UO2. Some older reactors used metallic natural uranium, while some other reactors use plutonium or a plutonium-uranium mix as fuel.
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.
Where is nuclear fuel generated?
Nuclear fuel is generated in nuclear reactors, where a process called nuclear fission converts uranium isotopes into energy. This energy is harnessed to generate electricity in power plants. The fuel is typically produced in specialized facilities where uranium is enriched and fabricated into fuel rods before being loaded into reactors.
What is nuclear fuel reactor?
In light water reactors it is uranium dioxide with the uranium enriched to 4-5 percent
Why do American nuclear plants use light water instead of heavy water in the reactors?
Mainly I believe because the light water PWR was developed for submarines and as compact a reactor as possible was required. Since then of course it (and BWR's) have been up-sized very successfully. Enriched fuel can now be made much more easily and cheaply by centrifuges than by the diffusion method, so to obtain low enriched fuel is more economical. There is also MOX available, though I don't think the US uses this. See the discussion page as well

What type of atom is used in nuclear reactors?
The fuel in current reactors is all uranium. Usually enriched to 3% uranium-235.Someday part of the fuel might be plutonium, either recycled from bombs or made in breeder reactors. But not now.
What do nuclear power stations use as fuel?
Predominantly enriched uranium, but some reactors can use natural uranium.
What is the primary fuel in the majority of the world's nuclear reactors?
Uranium oxide, enriched to about 4 percent U-235
Does CANDU reactor use enriched uranium?
CANDU Reactors are specifically designed such that they do not require enriched uranium, and can operate entirely on naturally-occurring uranium. A CANDU design is generally used by parties that do not desire uranium enrichment facilities, due to the cost of those facilities. That said, a CANDU reactor CAN use enriched uranium, they are fully capable of supporting that fuel type.
What power plant uses uranium?
The majority of commercial nuclear power reactors use uranium (natural or enriched) as nuclear fuel.

The advantage of heavy water as coolant over light water in pressurized reactors?
In the CANDU reactor heavy water is used as the moderator. It is a much better moderator than light water because it does not absorb neutrons so strongly, and enables non-enriched uranium to be used. The heavy water moderator is enclosed in a tank with fuel channel tubes, called technically a calandria. The coolant is also heavy water which flows through the tubes and hence past the fuel elements, and then transfers its heat to a light water secondary circuit. In a PWR or BWR light water is used both as moderator and coolant, which is obviously much cheaper and less complicated, but does require uranium enriched in U-235.
What is Uranium used to produce fuel?
Reactors can use low enriched or natural uranium.Uranium dioxide or uranium carbide are the most common fuels today..
