They are not used commercially at present, but U-238 and thorium can be used to produce fissile material, in breeder reactors. The technology has been demonstrated in experimental plants but is not commercially attractive whilst there are plentiful supplies of uranium with U-235 enriched.
What else can I help you with?
What energy source is used for nuclear fuel rods?
The energy source used for nuclear fuel rods is the process of nuclear fission. In this process, the nuclei of certain heavy elements, such as uranium-235 or plutonium-239, are split into smaller nuclei, releasing a large amount of energy in the form of heat. This heat is then used to generate electricity in nuclear power plants.
What is nuclear energy released by?
In fission reactors, which are the only ones we have at present for useful power, energy is released by the fission of the nuclei of the nuclear fuel, usually uranium-235, but sometimes plutonium-239.
In a reactor what is nuclear energy produced in?
It is produced in the fuel rods by fission of the U235 nuclei. Each fission produces a certain amount of heat, and this is transferred to the water or gas which is pumped past the fuel, by contact heat transfer.
How does the process of nuclear fusion in the sun differ from nuclear fission in terms of energy production and sustainability?
Nuclear fusion in the sun involves combining light atomic nuclei to release energy, while nuclear fission on Earth involves splitting heavy atomic nuclei to release energy. Fusion produces more energy and is more sustainable than fission because it uses abundant fuel sources and produces less radioactive waste.
Breeder reactors are used to convert?
Breeder reactors are used to convert non-fissile isotopes (such as U-238) into fissile isotopes (such as Pu-239) through neutron capture reactions, thereby producing additional fuel for nuclear reactors while generating energy. This process allows for the sustainable use of nuclear energy by recycling and reusing nuclear fuel.
Is fuel enrichment done for thorium?
No, Thorium is a fertile nuclear material.
Which element is used as a fuel in nuclear reactors?
Uranium-235 is commonly used as a fuel in nuclear reactors. When uranium-235 nuclei undergo fission, it releases energy that can be harnessed to generate electricity.
How is nuclear energy in stars?
Stars obtain energy through the majority of their lives by the process of thermonuclear fusion of the nuclei of light elements to produce nuclei of heavier elements. Initially the processes fuses hydrogen nuclei, producing helium nuclei (similar to what hydrogen bombs do), but the process ceases when it produces nickel and iron nuclei at which point the star begins dying as it has run out of nuclear fuel.
What is Thorium breeder reacter?
In this type of nuclear reactor the fertile isotope thorium-232 is transformed in the fissile isotope uranium-233 and this act as a nuclear fuel.
What is nuclear energy if it is not renewable and not a fossil fuel?
It is energy stored by ancient supernovas in heavy nuclei like Uranium, when the stars exploded.It is also energy stored by the Big Bang in light nuclei like Hydrogen.This energy is stored in the Strong Nuclear Force as excess Nuclear Binding Energy.
What is nuclear energy made from?
In general, nuclear energy comes from the energy associated with atomic nuclei. There is nuclear fusion, which happens in stars and in fusion weapons, and there is nuclear fission. Nuclear fusion is the "combining" of lighter atomic nuclei to create heavier ones, and many fusion reactions release energy. (Again, think of stars.) In contrast, nuclear fission is the "splitting" of atomic nuclei to release energy. The latter is technology that we've come to use fairly widely, and we have developed fission nuclear weapons and the nuclear reactor to tap nuclear energy via fission. Let's look at the latter device, the reactor. The fission of nuclear fuel (also known as atomic fuel, such as uranium or plutonium) is where we get nuclear energy. And what happens during nuclear fission is that the nuclei of fuel atoms absorb neutrons and fission (split), releasing lots of energy. In fission, that larger atomic nucleus breaks into a pair of smaller ones, and these fission fragments recoil with a lot of kinetic energy. The fuel traps the fission fragments, and the energy they came away with is converted into thermal energy in the fuel. We derive nuclear energy by tapping the energy of formation of atomic nuclei via fusion or fission. This is advanced technology that is less than a century old. We're still working to use it well and wisely.
Where does nuclear energy get its power?
From the fissioning of the nuclei of uranium235 and plutonium239. The energy released appears as thermal energy in the surrounding fuel material
What energy source is used for nuclear fuel rods?

In this process, the nuclei of certain heavy elements, such as uranium-235 or plutonium-239, are split into smaller nuclei, releasing a large amount of energy in the form of heat.

What do nuclear scientist call a stick of uranium?
A stick of uranium is typically referred to as a fuel rod in the nuclear industry. These fuel rods are used in nuclear reactors to sustain a controlled fission chain reaction, producing heat that is converted into energy.
What is the process of splitting of a heavier nucleus into lighter with the release of energy called?
Fission is the word you are looking for, but the less massive nuclei of the daughter atoms are usually far less stable than the nucleus of the parent, which is why nuclear waste from plant that uses uranium as fuel is extremely dangerous but nuclear fuel for the plant is not.
Why is uranium 238 not used as fuel?
Uranium-238 is a fertile nuclear material that is useful in producing fissile material (Plutonium 239)
Do nuclear power plants make electricity from fossil fuel?
No. Nuclear power plants use a uranium to provide the heat to generate electricity from. By splitting the nuclei of uranium atoms (called nuclear fission), energy is released, which will be used for electricity generation. Uranium is a radioactive metal, not a fossil fuel.
