What is induced nuclear fission?
We might think of induced nuclear fission as a fission reaction that occurs when a neutron is captured by, say, a uranium-235 atom and that atomic nucleus undergoes fission as a result. Most all of the fission events within a nuclear reactor or nuclear weapon are induced. Given this, we might then compare that fission event to a spontaneous fission event wherein the atomic nucleus of a uranium-235 atom spontaneously undergoes fission without having captured a neutron.
What are the three isotopes that will undergo neutron induced fission?
They are many but the most famous three are: uranium-233, Uranium-235, and Plutonium-239.Another answerUranium-235, uranium-238, and plutonium-239 are all capable of undergoing neutron induced fission. Actually there are other isotopes that also do this, but they are not commonly used as fuel.
In a nuclear fission reaction a freely moving neutron?
In a nuclear fission reaction, a freely moving neutron undergoes neutron capture and initiates the nuclear fission of a fuel atom.
What are the daughter atoms of uranium-235 during the initial chain reaction?
Fission is a form of nuclear transmutation because the resulting fragments are different elements from the original atom. A neutron-induced fission of U-235 results to krypton and barium.
What is fission cross section in nuclear reactor?
The fission cross section in a nuclear reactor is a measure of the probability that a neutron will induce fission in a particular nucleus. It is a crucial parameter for determining the neutron flux and reaction rates within the reactor core. Different isotopes have different fission cross sections depending on their ability to undergo fission when struck by a neutron.

What has the author John Gary Owen written?
John Gary Owen has written: 'The calibration and use of a helium-3 spectrometer to measure delayed neutron spectra following neutron-induced fission of uranium-235 at several fission energies'

What is James Chadwick most famous for?
James Chadwick is most famous for his discovery of the neutron in 1932, which revolutionized the field of nuclear physics and earned him the Nobel Prize in Physics in 1935. His discovery led to the development of nuclear fission and the atomic bomb.

What is the bullet that starts a fission reaction?
The bullet that starts a fission reaction is a neutron. When a neutron collides with the nucleus of a fissile isotope, such as uranium-235, it can induce the nucleus to undergo fission, releasing more neutrons and a large amount of energy.

It is a crucial parameter for determining the neutron flux and reaction rates within the reactor core.

In the twentieth century what were two ways nuclear fission happened?
Nuclear fission happens spontaneously in nature. Uranium-235 does this, and is the only commonly occurring natural isotope that does. Nuclear fission can be induced by crashing a neutron into a fissionable atom. Some things other than Uranium-235 are fissionable, notably Uranium-238. Fission has been induced in various experiments. It happens in nuclear reactors and in nuclear bombs.
Is used in nuclear fission?
all you need in nuclear fission is a large element (235Uranium) and a neutron, the neutron goes into the Uranium causeing it to split into smaller parts grapes.
How can a sample of uranium-235 that has critical mass be induced to react in a controlled nuclear fission reaction?
To induce a controlled nuclear fission reaction in a sample of uranium-235 with critical mass, the sample needs to be bombarded with neutrons. This process, known as neutron bombardment, triggers the splitting of uranium-235 atoms, releasing energy and more neutrons to sustain the chain reaction. By controlling the rate of neutron bombardment, scientists can regulate the fission process and harness the released energy for various applications, such as generating electricity in nuclear power plants.
What is the particle required to continue the chain process of Uranium fission?
A neutron is the particle required to continue the chain process of Uranium fission. When a Uranium-235 nucleus absorbs a neutron, it becomes unstable and splits into two smaller nuclei, releasing energy and additional neutrons that can then go on to induce further fission reactions in nearby nuclei.
