Let us share some knowledge of Nuclear Reactor.

The two largest producers of uranium are Canada and Australia.
nuclear reactor produces and controls the release of energy from splitting the atoms of elements such as uranium and plutonium. In a nuclear power reactor, the energy released from continuous fission of the atoms in the fuel as heat is used to make steam. The steam is used to drive the turbines which produce electricity (as in most fossil fuel plants

Electricity Generation

Nuclear reactors produce electricity by heating water to make steam. The steam is then used to drive turbines that generate electricity. In this sense nuclear reactors are similar to other thermal power stations, where the heat from burning coal or gas is used to produce stream. A key difference of nuclear reactors is that they don't emit carbon dioxide. A nuclear chain reaction is so-called because when a U-235 atom splits (or fissions) in the reactor's core the neutrons released cause other uranium atoms to also undergo fission. A moderator slows down the neutrons to achieve this. The nuclear reactor uses control rods to ensure that this chain reaction occurs at a controlled rate.

Used Fuel Management

Used fuel from a nuclear reactor is first stored to allow most of the radiaoactivity to decay. Then it can either be reprocessed to recover the reusable portion, or it may be disposed of directly as waste. In reprocessing, the used f fuel is dissolved and the uranium and plutonium in the used fuel are separated from the waste fission products. Plutonium can then be combined uranium to make Mixed Oxide Fuel (MOX), which can be used in many modern reactors. Reprocessed uranium can be used in new uranium oxide fuel.
