THE advantages and disadvantages of Nuclear energy
Day after day, the energy required in the world increases. Fossil fuels have been used for energy since the outset of the last century. The burning of these fossil fuels over the years has caused the earth’s temperature to increase. Some countries are concerned about this problem, and tend toward finding alternative power sources.
Iran chooses nuclear energy to decrease poison gases, but this choice has met with the disapproval of many countries like the European Union, USA and Israel fearing an Iranian nuclear weapons program. In my opinion, Iran is entitled to make a beneficial and safely maintained nuclear power station. Nuclear power has a lot of important advantages which I will talk about it in the context of nuclear power production.
The first nuclear power station was established in England in 1956. Nuclear power is generated by using uranium metal, which is mined in various parts of the world. Some military aircraft carrier and ships use nuclear power for engines. Nuclear power produces around 12% of the world energy required, and produces large amounts of energy from small amounts of fuel, without the comparative pollution produced by burning fossil fuels.
Nuclear power stations work in the same way as fossil fuel burning stations, except that a chain reaction inside the nuclear reactor produces the heat instead of the fuel. The reactor uses uranium as fuel, and the heat is generated by nuclear fission. Neutrons smash into the nucleus of the uranium atoms, which split in half and generate energy from the heat. Carbon dioxide gas is pumped through the reactor to remove the heat, and the hot gas then heats water to make steam. The steam drives turbines which in turn drive generators. Modern nuclear power stations use the same type of turbines and generators as conventional power stations.
In England, nuclear power stations are built on the coast and use sea water for cooling. These...
