The Nuclear Power Data-Bank

ü Russia built the first nuclear power station in 1954.

ü The fuel which nuclear power stations use is a rare metal – uranium. One tonne of uranium can produce as much energy as 20,000 tonnes of coal.

ü Electricity from nuclear power is far more expensive than energy from oil.

ü These countries all produce uranium... Russia, Canada, America, South Africa, Australia, China.

ü Nuclear power doesn't pollute the atmosphere like fossil fuels. But it does produce waste. This stays radioactive for thousands of years and is very dangerous. At the moment most stations

¨ bury their waste deep underground.

¨ bury their waste at sea.

¨ send their waste to other countries. (Britain, for example, accepts and buries nuclear waste from several countries.)

ü Nuclear experts say it's safe to bury radioactive waste. Other scientists aren't so sure. Many think it will seriously pollute the sea or the Earth one day.

ü Another problem for the nuclear industry is leukaemia. This is a cancer of the blood. Usually it's very rare – but not near several British nuclear power stations. There, the number of people with the disease is much higher than normal. Many of them are children.

ü Nuclear power stations are never in cities. That's because of the possibility of accidents. There have already been several serious ones. For example:

¨ Sellafield (UK, 1957)

¨ Three Mile Island (USA, 1979)

¨ Chernobyl (USSR, 1986)

ü The accident at Chernobyl sent a cloud of radioactive pollution over Scandinavia and Western Europe. This pollution travelled for more than 1,000 kilometres. As a result, farmers had to kill millions of pigs, sheep and cows. But the accident didn't just affect animals – it affected people, too. Doctors expected to see 25.000 extra cancers before the year 2000 because of Chernobyl.

ü Since Chernobyl, many countries have stopped building new nuclear power stations. Many, but not all. France, for example, still believes in the future of nuclear energy. But other countries, like Sweden and America, are less sure now than in the '60s or '70s.

ü Green organizations all over the world are against nuclear energy. In their opinion it's dirty, unhealthy and dangerous.

Now that you know more about nuclear and other traditional sources of energy, compare them with the new alternative ones. Which of them do you consider most efficient? Why?
