Thermal neutrons have a higher probability of inducing fission because they have the right energy level to be captured by fissile nuclei like uranium-235. When a thermal neutron is absorbed by a uranium-235 nucleus, it becomes unstable and can split into two or more smaller nuclei, releasing more neutrons and energy in the process. This chain reaction is the basis of nuclear fission reactions in reactors.

Neutron moderation is used to counteract what?
the minimal chance that newly formed neutrons of a fission reaction are absorbed by more atoms. (apex)
A nuclear fission chain reaction of U-235 starts with a slow neutron. What produces this first neutron?
The first neutron in a nuclear fission chain reaction can be produced by a neutron source such as a neutron generator or a nuclear reactor. In a reactor, neutrons can also be emitted from decaying fissile material such as U-235 or Pu-239.
How can the fission be controlled or stopped in a nuclear reactor?
Fission in a nuclear reactor can be controlled or stopped by inserting control rods made of materials like boron or cadmium into the reactor core. These control rods absorb the neutrons that are necessary to sustain the chain reaction, thereby slowing down or stopping the fission process. The control rods can be moved in or out of the reactor core to regulate the rate of fission reactions.
What happend to lone neutrons?
Lone neutrons are inherently unstable and can decay into a proton, an electron, and an antineutrino through beta decay. This process allows the neutron to transform into a more stable configuration. In certain conditions, lone neutrons can also be captured by a nucleus to form a heavier isotope.
Why are neutrons used as nuclear bullets to cause nuclear disintegration of an unstable nucleus?
Neutrons are used as nuclear bullets to cause nuclear disintegration because they have no charge, allowing them to penetrate the positive charge of the atomic nucleus easily. When a neutron is absorbed by an unstable nucleus, it can make the nucleus become more unstable, leading to nuclear disintegration through processes like fission or neutron capture. This can result in the release of energy and the formation of new elements.
What does neutron moderation counteract?
the minimal chance that newly formed neutrons of a fussion reaction are absorbed by moore atoms

What is neutron moderation used to counteract against?
Neutron moderation is used to counteract against the high speed (fast) neutrons produced during nuclear fission. By slowing down the neutrons through moderation, they are more likely to cause further fission reactions in nuclear reactors, sustaining the chain reaction.

How is a uranium-235 nucleus made to undergo fission?
A uranium-235 nucleus can undergo fission when bombarded with a neutron, leading to the nucleus splitting into two smaller nuclei and releasing additional neutrons and energy. This process is typically initiated in a controlled manner in nuclear reactors to generate power.
If your sister is a twin what is your chance of having twins?
actually u have a greater chance of twins then
Is it a greater chance of landing on boardwalk or Illinois on monopoly?
Every site on the board has an equal chance.
Why immigrants came to cities?
for a greater chance of employment
What dog has a greater chance of biting?
Pit Bulls
What does Vincent say that a child conceived in love has a greater chance of in the movie 'Gattaca'?
Vincent said, "They used to say that a child conceived in love has a greater chance of happiness."
How does binary fission result in bacteria becoming resistant to antibiotics?
the genes of the bacteria have to be replicated, allowing for the chance of genetic mutation.
Which value shows a greater probability that the result did not occur by chance 0.05 or 0.001?
In the context of significance tests, the value of 0.001 indicates a lesser likelihood that the event occurred by chance, that is a greater probability that it did not occur by chance.In the context of significance tests, the value of 0.001 indicates a lesser likelihood that the event occurred by chance, that is a greater probability that it did not occur by chance.In the context of significance tests, the value of 0.001 indicates a lesser likelihood that the event occurred by chance, that is a greater probability that it did not occur by chance.In the context of significance tests, the value of 0.001 indicates a lesser likelihood that the event occurred by chance, that is a greater probability that it did not occur by chance.
