NUCLEAR ENERGY


Nuclear energy has got a very bad reputation, but it is the most widely used.

Nuclear energy is more efficient than other types of energy such as fosile fuel. People think it is dangerous. The nuclear waste is more dangerous than a nuclear energy plant. Nuclear waste is active for around 500.000 years. But it depends on the radioactivity degrees. There are three levels: high, medium and low radioactivity. In the first level it is uranium, in the second level is contaminated water, and there are staf in the third level where they are wearing staf´s clothes.

In my opinion nuclear energy is the most efficient and secure. I don´t like it because the nuclear waste. People do not trust nuclear energy, because it has happened many nuclear catatrophes in the world, Three Mile Islands, USA, Chernobyl,Ukraine, although they have been caused by human errors.
