Tchernobyl

  • Nuclear Power Plant ( Centrale Nucléaire )
  • First use in 1977
  • First, it was built with 2 reactors
  • Then added 2 more ( 3rd and 4th)

How does a nuclear energy pot works?

2

  • Throw a neutron into an Uranium atom
  • Then, the Uranium atom will split in tow
  • This process will create a lot of energy ( heat )
  • This heat will boil water and steam it.
  • The steam will spin turbines
  • Thoses turbines will spin a generator that will make electricity

The night of the 25th april 1986 , the fourth reactor exploded.

What happend?

Its nominal power was 3200 MWh.
It climed to 32000 MWh !

It exploded because of a pilot error. Anatoli Diatlov is the guy who exploded it.

What after ?

Tchernobyl ( in a radius of 30 km ) will still be radioactive for 48 000 years.

If the reactor had had a protection, the explosion would have done nothing.
In Three Mile Island, there was a protection so, the explosion done nothing.

A radioactive cloud flew over Europe. France was touched in three quarters. ( 3/4 )
