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.
Isotope of uranium used in nuclear reactors?
Uranium 235 is the most important isotope of uranium; it is a fissionable isotope used in HWR, PWR, BWR, research reactors and other types of reactors. But it is rare, only 0.72% of natural Uranium is this isotope.The more plentiful Uranium 238 isotope is only fertile not fissionable; it can only be used in fast reactors to breed Plutonium, which is fissionable. Isotopes of plutonium 239Pu and 241Pu are highly fissionable and importants for nuclear fuels.
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.
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.
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
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

Why does Russia want nuclear waste?
The only reasons I can think of for such a want is money (which can be charged for taking the waste; in Russia they have enough space to do so safely) and recycling the waste (thus gaining more fissionable material for free, provided you can get it out of the waste).
The differences between nuclear reactors and nuclear bombs include what?
Nuclear reactors produce exactly one additional fission for each fission reaction while nuclear bombs don't Nuclear bombs are runaway fission reactions and reactors aren't (APEX)
What type of reactor produces more fuel than it consumes?
a fission nuclear reactor -binky
Are the atomic bomb and depleted uranium the same weapon?
No, the atomic bomb and depleted uranium are not the same thing. Nuclear weapons are made with enriched uranium or with plutonium as the fissionable material. Depleted uranium is uranium that is "left over" after natural uranium is put through a process called enrichment to inprove the concentration of the isotope U-235 over that in natural uranium. The enriched uranium with its higher percentage of U-235 is fissionable, and it can be used in nuclear reactors and in nuclear weapons. Depleted uranium is used to make armor-piercing projectiles, and can be put through the neutron flux in an operating reactor to be transformed (transmuted) into plutonium.

What is the difference between homogeneous reactor and heterogeneous reactor?
Homogeneous reactor- the reactor where one phase exist for both the reactants. Hetrogenous reactor - the reactors where more than one phase exist among the reactants gas-liquid-solid.
How many pounds of uranium are in a nuclear reactor?
The quantity depends on: the type of the reactor, power of the reactor, enrichment of uraniu, chemical form of the fuel, etc. For a research reactor some kilograms, for a power reactor more than 100 tonnes/year.
