NUCLEAR POWER PLANTS - How do they work?

Nuclear power stations work in pretty much the same way that the burning of fossil fuels, the seasons, except that a "chain reaction" inside a nuclear reactor makes the heat instead. The reactor uses Uranium fuel rods.the steam moves turbines powering generators. Modern nuclear plants use the same type of turbines and generators in conventional power stations. In Britain, nuclear power plants are often built on the coast, and use sea water for cooling the steam ready to be pumped round again. This means that they don't have the huge "cooling towers" seen at other plants.

Where can you find plants of these source and why?

  • Pakistan
  • Slovenia
  • The Netherlands
  • Armenia

Because nuclear power plants produce more energy than other power plants. Can they be used in Spain? Why/ Why not? Yes, because needs energy, and nuclear power plants is a method of obtaining it.


Is it expensive? - Yes, it is, because is very difficult to obtain it, and very difficult to mantain it too, and it's very dangerous because it creates much nuclear waste, and it produces a lot of energy.


What is the efect on the environment? - Nuclear energy has got a negative impact on living creatures. The radioactive contamination can negatively affect the air, the ground and water and can thus produces mutations.Nuclear accidents produce enormous contamination which can extend in all directions and cause massive damage to the environment. Nuclear power stations have to be situated away from densely populated areas. Are you dependent on other countries/people when you want to generate electricity? - It is dependent on other countries because it needs uranium.

How much electricity is generated in one plant? - It depends on its reactor. However, the more enriched uranium fission is, the more energy is produce.

What are the advantages and disadvantages of this energy source?

ADVANTAGES: Nuclear power costs about the same as coal, so it's not expensive to make.

  • It does't produce smoke or carbon dioxide, so it does not contribute to the greenhouse effect.
  • It produces huge amounts of energy from small amounts of fuel.
  • It produces small amounts of waste.Nuclear power is reliable.

DISADVANTAGES: Although not much waste is produced, it is very, very dangerous.

  • It must be sealed up and buried for many thousands of years to allow the radioactivity to die away.
  • For all that time it must be kept safe from earthquakes, flooding, terrorists and everything else. This is difficult.

Nuclear power is reliable, but a lot of money has to be spent on safety - if it does go wrong, a nuclear accident can be a major disaster. People are increasingly concerned about this - in the 1990's nuclear power was the fastest-growing source of power in much of the world. In 2005 it was the second slowest-growing.


Is it sustainable? Nuclear power is essentially sustainable. No nuclear power station has yet burnt itself out naturally. What might happen, however, is that governments could decide to end power plant's useful life for security reasons.
