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.
Does a breeder reactor use uranium as a fuel?
Yes, a breeder reactor uses uranium as a fuel. Specifically, it uses a specific isotope of uranium, such as uranium-235 or uranium-238, to sustain a nuclear chain reaction. The reactor can also produce more fissile material, like plutonium-239, through breeding reactions.
Why do they use uranium in power stations?
Because uranium-235 can easily be made to fission in a reactor with a moderator to slow the neutrons down, a chain reaction can be sustained, and heat is generated which can be harnessed for electricity. Uranium is usually used because it is the largest naturally occurring atom. A smaller atom would not split as easily, and a larger atom would first need to be created before it could be split.Also Uranium-235 is the only isotope capable of undergoing fission and supporting a chain reaction of any element on earth that occurs naturally at high enough levels (0.72% of natural Uranium) to make it economically extractable. Other fissionable materials have to be produced in sufficient quantities in "breeder reactors" where the radiation converts certain non-fissionable elements into other fissionable elements through neutron capture. Because uranium is much more common that was believed early in the development of nuclear reactors, it is much more economical to refine naturally occurring uranium (separating the U-235 from U238) than to use breeder reactors to convert non-fissionable isotopes into fissionable ones and then refine the result to produce more nuclear fuel.A very slightly different world (e.g. older) and nuclear energy and weapons might never have been possible at all.
Why is water located above the earths crust but below the air?
Because it is less dense than the material that makes up the earth's crust, but more dense than the material that makes up the air.
What does a breeder reactor produce?
Well, simply put, both are nuclear reactors. A breeder reactor is one which instead of losing it's neutron production to capture in moderators or shielding elements, absorbs most of the neutron production in the fuel specifically for the production of transuranic elements. Such reactors have been used since the 60's to facilitate in the production of fusion nuclear weapons, also known as hydrogen bombs, as these require large amounts of plutonium which can only be created in a breeder reactor. The U.N. has been discouraging the use of breeder reactors since the mid nineties and many worldwide have been shut down. This is in part due to their use in the proliferation of nuclear weapons and due to their inherent instability. There are literally dozens of types of nuclear reactors, breeders being only one. Others include pressurized water reactors, boiling water reactors, graphite moderated reactors, lead cooled reactors, or the more recent pebble bed reactors.
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.
Where does the reaction occur in nuclear fission?
Nuclear fission reactions typically occur in the core of a nuclear reactor. This is where the fissionable material, such as uranium-235, is bombarded with neutrons, causing the nuclei to split and release more neutrons and energy in a chain reaction.
How are breeder reactors different from regular nuclear reactors?
A breeder reactor generates (in a way) new fuel, sometimes more fuel than it uses, by converting non-fissionable isotopes into fissionable isotopes, through neutron capture.
What are feeder reactors?
Probable you think to a breeder reactor; this type of nuclear reactor produce more fissile material than it consumes.
How is plutonium-239 produced in a breeder reactor?
Plutonium-239 is produced in a breeder reactor when uranium-238 absorbs a neutron and undergoes two beta decays to become plutonium-239. This process allows the breeder reactor to create more fissile material than it consumes, making it a sustainable source of nuclear fuel.
Is breeder a noun verb or adjective?
The word breeder is a noun, a singular, common noun; a word for a person who breeds animals or plants; an animal kept to produce offspring; a nuclear reactor designed to produce more fissionable material than it uses as fuel (a breeder reactor). The verb form is to breed, breeds, breeding, bred. The adjective form is the present participle of the verb, breeding (breeding stock), and the past participle, bred (often applied to a person as a well bred person).
Are there more are there one type of nuclear reactor?
the boiling water reactor, pressurized water reactor, and the LMFB reactor
Can a nuclear reactor make more fuel than it uses?
Yes, a type of fast neutron (without a moderator) reactor called a breeder reactor can make plutonium fuel much faster than it consumes uranium fuel. If fueled with plutonium fuel instead of uranium fuel, it also makes more plutonium fuel than it consumes.But all other reactor types are unable to do this (even though they all make some plutonium during operation).Note: a slight variant of a breeder reactor sometimes called a burner reactor is designed to rapidly fission all actinides (elements from actinium up through all transuranics) to eliminate long lived isotopes from nuclear waste.
Location of prototype fast breeder reactor?
The advantage is mainly that more active fuel can be created than is used, so getting 'something for nothing'. However experimental reactors such as the sodium cooled fast reactor at Dounreay in Scotland have proved very difficult in practice, with material problems, and as far as I know such experiments are in abeyance at the moment.
Difference between breeder reactors and nuclear reactors?
The nuclear reactor is different from the breeder reactor because it generates energy through fission. Historically, in order to be called a breeder, a reactor must be specifically designed to create more fissile material than it consumes. this is what I've looked up and been able to find
Which Fuel is used in Fast Breeder Reactor?
Fast Breeder Reactors typically use a combination of plutonium-239 and uranium-238 as fuel. This type of reactor produces more fissile material than it consumes, making it an efficient way to generate nuclear power.
What type of reactor produces more fuel than it consumes?
a fission nuclear reactor -binky
