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… Full Answer
Uranium is a radioactive element; the isotope 235 is fissile with thermal neutrons; the isotope 238 is not so fissile but is fertile (transformation in the fissile isotope plutonium 239). Consequently, uranium is a good nuclear fuel and also can… Full Answer
The purpose of a breeder reactor is to produce fissile fuel from non-fissile material. Thus plutonium can be bred from uranium238 which is the most common form of uranium but is not itself fissile. Another route is to breed Uranium… Full Answer
Uranium-238 is fissionable. Its just not what we call fissile, which has the added definition of, when fissioned, producing neutrons that can go on to fission more atoms. Uranium-238 is more correctly called fertile, which means that a neutron can… Full Answer
I think you mean Pu-239, but we'll look at both Pu-239 and Pu-238 We'll compare to aspects, the decay energy and the fissile energy. First the decay energy. U235 alpha decays and releases 4.679 MeV in the process Pu238 alpha… Full Answer
It is not renewable. There is a fixed amount of fuel on earth and it cannot be increased. Even when people talk of breeder reactors, they are only breeding fissile fuel from non-fissile material, which is itself non-renewable.
Because these are the only two elements (isotopes: Uranium 235, plutonium 239 and plutonium 241, fissile with thermal neutrons) that have fissile isotopes which can sustain a chain reaction in conjunction with a moderator, that is in a so called… Full Answer
Thorium can be used as fertile material (as ThO2) in nuclear power reactors; is a precursor of the fissile isotope 233U. This type of reactor is called a breeder: the reactor produce more fissile material than it consumes. It is… Full Answer
Nope. Industrial fissile materials are able to undergo sustainable and controllable chain-reactions given the right conditions. All you need to generate the primary energy is enough fissile material to allow this to happen, known as critical mass.
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… Full Answer
Uranium-235 is a fissile isotope: can react with thermal neutrons (fission) to sustain a chain reaction. Thorium-232 is a fertile material: can absorb neutrons without fission and is transformed in the fissile isotope U-233.
The fissile fuel is packaged in the bomb as a subcritical mass. The fusing system detects the preset firing condition. A firing pulse is sent from the fusing system to the rapid assembly system. The rapid assembly system uses explosives… Full Answer
Nuclear energy, ultimately, comes from the Sun. If you are talking about nuclear energy and weapons as currently available, we get Uranium from the Earth, as it is a naturally occurring element and refine it from 238U to 235U, making… Full Answer
You can't reuse energy after it has been used-this applies whether nuclear or not. What you can do with nuclear power is to breed useful fissile material such as plutonium from non-fissile uranium-238. However to separate out the plutonium is… Full Answer
