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.

How many kilos of uranium in a nuclear reactor?
Depending on the reactor type and power: from 1 kg to more than 100 000 kg.
How many nuclear reactor plant are in America?
104 operating nuclear reactors
How many watts does a nuclear reactor put out?
1.21 Gigawatts
What is the source of energy in nuclear reactor?
The source of energy in a nuclear reactor is the release of binding energy, i.e. the binding energy that hold protons and neutrons together in the nucleus of the atom. Heavy nuclides, such as uranium, are split into lighter nuclides, such as cesium and barium (and many others, in a semi-random cross section). The binding energy required to hold the original uranium together is less than the daughter products and is released to the system in the form of heat and other radiation.
How many people work in the nuclear reactors?
No one work inside a nuclear reactor, it is operated from outside.
Does nuclear reactors contain uranium-235?
It really depends on the nuclear reactor, but many are built to work specifically with that isotope.
How many kilos of uranium in a nuclear reactor?

How many days does a breeder reactor require to produce plutonium-239 from uranium-238?
It is a continuous instantaneous process that happens in the nuclear breeder reactor.
What are the example of nuclear fission?
The only example of nuclear fission in a naturally occurring material is of Uranium 235, which comprises 0.7 percent of natural uranium, the rest being Uranium 238 which is not fissile. To use U235 in a nuclear reactor it is usually enriched to about 4 percent first, though reactors have been designed to use natural uranium. These have to use graphite or heavy water as moderator, as normal water absorbs too many neutrons. During reactor operation some of the U238 absorbs a neutron and becomes Plutonium 239 which is also fissile, so this contributes to a proportion of the reactor power which increases as the fuel is used and the U235 diminishes.
Why are only uranium and plutonium used in nuclear reactors?
Because these are the only two elements (isotopes: Uranium 235, plutonium 239 and plutonium 241, fissile with thermal neutrons) that have fissile isotopes which can sustain a chain reaction in conjunction with a moderator, that is in a so called thermal reactor like PWR or BWR. Uranium 238 is fissile with fast neutrons though it will not sustain a chain reaction by itself, and would only be a significant source of power in a fast reactor. In a thermal reactor it captures neutrons and forms Pu-239 which then does add to the reactor's fissile fuel. Some other transuranic elements have fissile isotopes but they are not used as it is much easier and cheaper to use uranium produced from uranium ore. Also thorium can be used in nuclear reactors as a fertile isotope.
How many houses could be powered with a nuclear reactor?
That depends on the power rating of the reactor.

How many methods are there to give heat to the reactor?
If you mean a nuclear reactor, and not a chemical one, there is only one way, and that is by nuclear fission in the fuel
What country uses the least amount of uranium?
Many countries without uranium mines, nuclear reactors, nuclear weapons.
What radioisotope is used as the fuel for a nuclear reactor?
There are two radioisotopes that serve as fuel for a nuclear reactor. The first is uranium-235, which is a constituent of natural uranium. U-235 is a "fissile" isotope -- i.e., the one that splits when it absorbs a neutron of a certain energy. When a reactor starts up with a fresh load of fuel, all of the early activity involves U-235. This splitting, or fissioning, of U-235 atoms releases energy in the form of heat. The production of heat is the whole purpose of certain types of nuclear reactors. This heat converts water into steam to turn a turbine generator and make electricity. Fission also releases neutrons. These neutrons sometimes are absorbed into another uranium isotope, uranium-238, another constituent of natural uranium which is also present in nuclear fuel. When U-238 absorbs a neutron, it eventually becomes plutonium-239. Pu-239 is another fissile isotope, i.e., it also fissions when struck by a neutron of a certain energy. So the two isotopes that are used as fuel for a nuclear reactor are uranium-235 and plutonium-239. The former gets the reactor going; the latter is made inside the reactor. Some nuclear reactors are designed solely to produce neutrons. These are research reactors. Neutron interactions with other materials are of great interest to a great many scientists and engineers.
