Nuclear power
In 2018, nuclear energy generated around one fifth of the country's electricity. A huge amount of energy can be produced through the nuclear process using a relatively small amount of uraniumA very heavy metal that is naturally radioactive and is common in the Earth's crust.. The energy is produced as heat through the nuclear fissionThe splitting of a large nucleus to produce two smaller ones. Two or three neutrons are also released in the process. The energy from the neutrons powers a nuclear reactor. .
atomThe smallest part of an element that can exist. are split, and this energy is used to convert water into super-heated steamWhen water boils it forms a visible mist of water droplets called steam.. This spins turbineRevolving machine with blades that are turned by wind, water or steam. Turbines in a power station turn the generators. connected to electrical generatorDevice that converts kinetic energy into electrical energy. to produce electricity.
Advantages of nuclear | Disadvantages of nuclear |
No harmful gases are released in the process | Nuclear power stations have to close after around 40 years of use when the uranium becomes less efficient at heating the water |
More efficient than fossil fuels | Disposal of uranium is difficult and costly |
Cost of nuclear power stations is very large |
