INTRODUCTION


Concern remains over the potential effect on human health if there is leakage from any nuclear plants. A 20km (12 mile) evacuation zone affecting about 70,000 people has been imposed around the plant.Residents living within 30km (18 miles) have been advised to leave the area, or to stay indoors, and try to make their homes airtight.Experts believe that swift action of this sort should have minimized the risk to human health, but are worries about the level of radiation to which emergency workers have been exposed, and about possible contamination of food and water supplies.

Advantages
  • Nuclear power costs about the same as coal, so it's not expensive to make.nuclear_cartoon.gif
  • Does not produce smoke or carbon dioxide, so it does not contribute to the greenhouse effect.
  • Produces huge amounts of energy from small amounts of fuel.
  • Produces small amounts of waste.
  • Nuclear power is reliable.

Disadvantages

  • Althogh 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.
