coucou
mercredi je fait un petit exposé (10 min) sur un article de presse sur tchernobyl en anglais et voila ce que je vais dire, si des popines prof d'anglais ou canadiennes ou bilingues pouvaient me dire s'il y a des fautes ce serai super parce qu'il y a des trucs je savai pas trop alors j'y suis allé au felling !
merci d'avance les popines ca m'ai derai bcp
Today, I am going to speak about the Chernobyl disaster.
The text is a press article extracted from the « Scientific American » of April 1996.
This disaster occured on the morning of April the 26th in 1986.
The operators were driving a test to see how long the generators would be able to run without energy.
I remind you that in a nuclear power station the reactors produce steam which operate generators, and it’s the generators which produce electricity.
To realise this test, the operators greatly reduced the power made by the reactor number 4 and they blocked the flow of steam to the generator.
That was the first mistake because this RBMK reactor has a flaw that make it very unstable at low power.
Moreover, due to an opperational error the power felt too much, about 30 MW instead of 1000 MW.
In fact, you can contol the power with rods that you put in the reactor and it absorbs neutrons to slow down spliting.
The second mistake in this disaster was to switch off the safety system to permit continued the test.
At 1 AM, the situation had become dangerous so an opperator tried to activate the protection system but it was too late.
Then, the power reach 100 times the maximum power, the temperature increase and the reactor explode. There were too explosions that blast the top of the reactor which weighted 2000 tons of graphite that had componed the moderator burned for 10 days. The moderator is to slow down the speed of neutrons for a good spliting.
This fire carried fuel particules made of uranium and plutonium, which are are dangerous elements, and others radioactives products.
About 5000 tons of various materials were throw by helicopter to recover the reactor.
The lighter materials were carried by wind over Europe increasing, in others, thyroid cancer. The area of the nuclear power station was contaminated by radioactives fallout and many persons still live in contaminated areas.
As a conclusion, I want to say that thousand of people called « liquidators », had sacrified themselves in removing radioactive waste and building a sarcophagus around the reactor to avoid a larger collapse that will have involve an explosion 20 times bigger than the Hiroshima bomb. Europe would have been uninhabitable. This persons haven’t had suitables protections and most of them have died in agonizing pains.
