Fissionable material that cannot sustain nuclear reaction?
Fissionable material that cannot sustain a nuclear reaction on its own is called fissile material. Examples include uranium-238 and thorium-232. These materials can undergo fission when bombarded with neutrons but require additional enrichment or a moderator to sustain a chain reaction.
What are the two most commonly used fissionable substances?
The two most commonly used fissionable substances are uranium-235 and plutonium-239. Both of these materials undergo nuclear fission, releasing a large amount of energy that can be harnessed for power generation in nuclear reactors.
Is plutonium 239 fissionable?
Yes, this isotope is very fissionable and is used in nuclear reactors and nuclear weapons.
Fissionable fraction of fuel in a nuclear reactor?
In light water reactors the new fuel has about 4 to 5 percent U-235, which is the fissionable part, the rest being U-238. In some countries mixed oxide fuel is used (MOX) which contains some Plutonium as well as U-235, but the fissionable content is much the same. Heavy water or graphite reactors can use natural uranium, which contains 0.7 percent U-235.
What is the most conductive material for electricity?
The most conductive material for electricity is silver.
What is the quantity of fissionable material called that CANNOT sustain a nuclear reaction?
Subcritical mass is the quantity of fissionable material that cannot sustain a nuclear reaction. When the amount of fissionable material is below the critical mass required to sustain a chain reaction, it is considered subcritical.
What type of reactor makes more fissionable material?
A breeder reactor
What is the technology behind the atomic bomb?
Essentially, a core of fissionable material is impacted to such a degree that it will begin to undergo fission because of loose neutrons impacting the nuclei of the fissionable material. There are two methods, the first is by firing a bullet of fissionable material into a larger mass, and the second is by using conventional explosives to simultaneously concuss the material on all sides.
Fissionable material that cannot sustain nuclear reaction?
Fissionable material that cannot sustain a nuclear reaction on its own is called fissile material. Examples include uranium-238 and thorium-232. These materials can undergo fission when bombarded with neutrons but require additional enrichment or a moderator to sustain a chain reaction.
The smallest amount of a fissionable material that will give a self-sustaining chain reactions is called the?
The smallest amount of a fissionable material that will produce a self-sustaining chain reaction is called the critical mass. This mass of affected by geometry and other factors such as temperature, pressure, and moderator.
Which type of fissionable material is used in an atomic bomb?
Either highly enriched uranium-235 or reactor produced plutonium.
Why does a chain reaction die out in small pieces of fissionable fuel but not in large pieces?
Because in small samples the probability of a neutron escaping the sample without inducing another fission is bigger. Actually, what matters is the mass of the sample, especially if this mass exceeds the critical mass. Thus, the chain reaction in a smaller sample with sufficiently higher density of fissionable material might not die out, while it dies out in a larger sample with albeit a sufficiently smaller density of fissionable material.
What is the amount of fissionable material required to continue a reaction at a constant rate?
The amount of fissionable material required to sustain a nuclear reaction at a constant rate is determined by the material's critical mass. The critical mass is the minimum amount of fissionable material needed to sustain a chain reaction, and it varies depending on the material and the reactor design. By controlling factors such as neutron moderation and absorption, reactor operators can adjust the critical mass to maintain a steady reaction rate.
What are the two most commonly used fissionable substances?
The two most commonly used fissionable substances are uranium-235 and plutonium-239. Both of these materials undergo nuclear fission, releasing a large amount of energy that can be harnessed for power generation in nuclear reactors.
How to make nuclear bomb-?
To make a nuclear bomb, you need the fissionable material such as a Plutonium239 isotope, an explosive to start the nuclear chain reaction, a detonator, and a pusher.
Why do nuclear reactors require a fissionable isotope?
The fissionable isotope is required for the nuclear reactor operation. The fissionable isotope when fissions it give energy due to the mass difference according to Einstein formula E = mc2
Is plutonium 239 fissionable?
Yes, this isotope is very fissionable and is used in nuclear reactors and nuclear weapons.
