Text chernobyl

Chernobyl was a nuclear power station in the Ukraine (which used to be part of the old USSR). The power station in Chernobyl was made in a way that has not been accepted in other parts of the world. British scientists had looked at the design but decided that it was dangerous, because the reactor did not have enough protection in case anything went wrong.

In the middle of a nuclear power station are one or more reactors, which get extremely hot. If they get too hot, the reactors blow up.

Very late at night on Friday 25th April 1986, some of the scientists at the Chernobyl power station decided to try a dangerous experiment. They changed the pressure in one reactor, which caused the temperature to rise. The reactor blew up.

At first, the scientists and the government did not want to say that a really serious accident had happened. However, in the next days and weeks after the accident, the government of Ukraine agreed that the air, food and water around Chernobyl were radioactive, and that it was dangerous for people to stay there.

The rest of Europe first heard about the Chernobyl accident not from the USSR, but from Sweden, where radioactivity was noticed at the Forsmark nuclear power station. Denmark and Norway also reported an increase in radioactivity, and the scientists of Western Europe finally realized that the radioactivity must be coming from near Kyiv in the USSR.

It was eighteen days before President Mikhail Gorbachev finally told the people of the USSR about the accident.

There is no doubt that the Chernobyl disaster was caused by human mistakes. The power station was not safe, and scientists at the power station were experimenting in dangerous ways. To make matters worse, the workers at the power station had no idea what to do in an emergency, and the government was extremely secretive.

The Chernobyl disaster had many effects on the electricity industry everywhere in the world. There had been nuclear accidents before, and many people had said for years that nuclear power was dangerous. This was the first really big accident that proved their warnings were right. Soon after the accident, many crowds of people met together in European cities. They held up notices with messages such as, 'Chernobyl is everywhere'.

Nuclear power was suddenly very unpopular, and governments had to look seriously for other ways of making electricity. That is why there is so much interest now in wind power and power from the heat of the sun.
