(presentation)
Good morning, ladies and gentlemen. First, let me introduce myself. My name is Peter Micenko and I’m student of The Department of Power Engineering at Faculty of Electrical Engineering and Informatics of Technical University in Košice. I’m going to talk today about nuclear power plants and their signification in the world. I would like to divide my presentation into three parts. Firstly, I`ll talk about how we produce electricity and what is its effect on environment. Secondly, I`ll define why are the nuclear power stations needed and finally I`ll describe the safety of the nuclear power plants. If you don’t mind, we’ll leave the questions until the end.
As you know, an electricity is a thing without which we can’t realize, we can’t image our usual day. Everybody of us uses it, but we don’t know how difficult, how hard is to produce it.So, if we want to produce the electricity, we must burn a quantity of coal, gas and oil. The exploiting, the burning of it cause the pollution of the atmosphere, and finaly it cause water pollution.
Unfortunately, the using of technologies often harms the environment. For example, the air pollution is a serious problem in many countries. Its negative results are a lung cancer and other health problems. In addition, the burning of oil, gas and coal gives rise to carbon dioxide in the atmosphere. To realize a harmful activity of it in the Earth atmosphere we can image a greenhouse. The carbon dioxide works like glass and when quantity of it increase in the atmosphere, the Earth becomes warmer, because less heat can escape.
If we want to change the Earth climate, we must stop the greenhouse effect. We should burn less gas, oil and coal in the future. We should build more power stations, which would be not so harmful to the Earth. However, not only carbon dioxide is produced by the thermal power plants. They produce additional chemical compositions, which are harmful to the environment and our health. We can change it by using of power plants that don’t burn the coal, oil and gas. You can see the emission of the thermal power stations in Slovak republic on the Graph No.1. Yes, we must do something! I think it is obvious, that energy consumption will grow in the future, but the raw material basis of the Earth is only for a few decades.
So, what to do? We have two alternatives.
