How much uranium 235 is used in a nuclear reactor?
Depending on the type and the power of the nuclear reactor. An example; a CANDU type reactor of 700 MW need 700 kg uranium-235 and only ca. 500 kg are "burned".
What gases do power plants let off?
It depends what type of power plant. A coal-burning power plant will produce CO2 and SO2, which are both pollutants. Nuclear power plants and geothermal power plants produce steam, which is not a pollutant. There are many other types of power plants, but most produce CO2 and SO2 or steam.
Why is water used in nuclear power plants?
Water is used in nuclear power plants to cool them and to be flashed to steam so that the energy generated can spin turbines to generate electricity. In light water moderated reactors, a very common type, water is also used as the neutron moderator, which means that it slows down the fast neutrons that are emitted from the fissioning of atoms of uranium so that they can participate in subsequent fission reactions with more atoms. This is a self modulating reaction, having a negative temperature coefficient, so the reactor's power level will dynamically track the load, with very little assistance from the operators.
How long does it take to make uranium for a nuclear bomb?
Depending on the size and type of the bomb and also on the enrichment installation available.
When a uranium nucleus breaks into fragments what type of nuclear reaction occurs?
In nuclear physics and nuclear chemistry, nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei), often producing free neutrons and photons (in the form of gamma rays).
What type of power is derived from uranium and thorium?
This power is the nuclear energy from the nuclear fission.
What type of nuclear power is used in powerplants?
Nuclear power from the fission of uranium and/or plutonium
What type of energy requires a uranium and a reactor?
Nuclear energy, because uranium is a nuclear fuel for nuclear power reactors.
How much uranium is need to power a nuclear power plant for eighteen months?
Depending on: - the type of the nuclear reactor - the electrical power of the nuclear reactor - the type of the nuclear fuel - the enrichment of uranium - the estimated burnup of the nuclear fuel etc.
How much uranium produces nuclear power?
The mass of uranium needed for a nuclear power reactor depend on the type and the power of this reactor. For a medium size reactor - 100 t.
What was the type of the nuclear core of hiroshima?
It derived its explosive power from the nuclear fission of uranium 235.
What type of plant uses uranium?
Nuclear power plants all use uranium to some degree. There are only two radioactive elements found on Earth in sufficient concentrations to mine that can be used for nuclear power. These are uranium and thorium. Thorium cycle power plants of various types are being researched and developed, but none are currently producing power for an electric grid. Uranium-233 is part of the thorium cycle, so uranium will be present in thorium cycle reactors, and its energy is used there. There are a number of nuclear plant designs that use plutonium, though they are not common. None is producing power in the United States. And even these also use uranium. In fact, the plutonium is produced from uranium.
What type of nuclear reaction is used to create power in nuclear power plants?
Nuclear fission
What particular type of atom do nuclear power plants take nuclear energy from?
Uranium-235 when started. After running a while they also burn transuranics like Plutonium-239 and Americium-241.
What type of energy does nuclear power plants start with?
Nuclear power plants are self starting because there is always a small number of fissions taking place in the uranium fuel, so as soon as the reactor is made critical by withdrawing the control rods the chain reaction starts.
What type of nuclear reaction are used in nuclear power plants?
fission
Which type of power plants generate the least amount of pollution?
nuclear power plants
