Fissile fuel primarily comes from uranium and plutonium, which are materials capable of sustaining a nuclear fission chain reaction. Uranium is mined from the earth, with the most common isotope being uranium-235, while plutonium can be generated in nuclear reactors from uranium-238. These materials undergo processing and enrichment to increase their concentration of fissile isotopes, making them suitable for use in nuclear reactors and weapons. Other fissile materials can also be derived from reprocessed spent nuclear fuel.

What uranium nucleus is fissile?
The isotopes 233U and 235U are fissile with thermal neutrons and the isotope 238U is fissile with fast neutrons.
What does it means if an isotope is fissile?
If an isotope is fissile, it means that it can undergo nuclear fission reactions when bombarded by neutrons. This process releases a large amount of energy and more neutrons that can sustain a chain reaction. Fissile isotopes are commonly used in nuclear reactors and weapons.
What is fissile nucleus?
A fissile nucleus is an atomic nucleus that is capable of undergoing fission when bombarded by neutrons. This process releases a large amount of energy, making fissile nuclei important for nuclear reactors and nuclear weapons. Examples of fissile nuclei include uranium-235 and plutonium-239.
What does it mean if a isotope is fissile?
A fissile isotope is one that can undergo fission when struck by a neutron, releasing energy and more neutrons that can then cause further fission reactions. This property is essential in nuclear reactors and nuclear weapons. Examples of fissile isotopes include uranium-235 and plutonium-239.
What is the difference between 'fissile material' and 'fissionable material'?
Fissile material refers to substances that can sustain a nuclear chain reaction upon absorbing a slow neutron, such as uranium-235 and plutonium-239. In contrast, fissionable material includes any substance capable of undergoing fission, which can occur with either slow or fast neutrons; this category encompasses both fissile materials and those that require fast neutrons to undergo fission, like uranium-238. Thus, all fissile materials are fissionable, but not all fissionable materials are fissile.
Why were breeder reactors developed?
Breeder reactors were developed to allow use of non-fissile or fertile fuel, such as uranium-238 and thorium-232, instead of fissile fuel, such as uranium-235 and plutonium-239. They do have fissile fuel in them, but they use its neutron flux to convert the non-fissile (fertile) fuel into fissile form, extending the lifespan of the core.
Is thorium used for nuclear genaration?
It can be used as a blanket fuel to produce U-233 fissile fuel.
Is nuclear an atomic fuel?
Fuel used in a nuclear reactor is uranium, the active isotope is uranium 235 which is fissile.
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.
What is a type of reactor that produces electricity but in doing so creates new nuclear fuel?
A breeder reactor is a type of reactor that produces electricity while also creating new nuclear fuel. It achieves this by converting non-fissile isotopes into fissile fuel as it operates, effectively "breeding" its own fuel.
What is fissile fuel in a atomic bomb?
Fissile fuel in an atomic bomb refers to materials like uranium-235 or plutonium-239 that are capable of sustaining a chain reaction in which atoms split and release a large amount of energy. These fuels undergo nuclear fission reactions, leading to the explosive power of the bomb.
Is thorium used in nuclear reactors?
Not as fuel, but it can be used in breeder reactors as breeding material to make fissile Uranium-233.
Why thorium is not used as fuel in nuclear reactors?
Thorium is and can be used as a fuel in nuclear reactors. It just happens to be not fissile, so it needs a neutron flux to create Uranium-233, which is fissile. There are pros and cons of using Thorium. For more information, please see the Related Link below.
Why is uranium 238 not used as fuel?
Uranium-238 is a fertile nuclear material that is useful in producing fissile material (Plutonium 239)
What uranium nucleus is fissile?
The isotopes 233U and 235U are fissile with thermal neutrons and the isotope 238U is fissile with fast neutrons.
What is nuclear breeding?
This means the breeding of fissile material from non-fissile. Thus for example Pu239 results from irradiating U238 which is not fissile. Thorium can also be used to breed fissile uranium.
What does it mean when the isotope is fissile?
"Fissile" means "capable of undergoing fission."
