NUCLEARE POWER_____YIN JUHAO

TECHNOLOGY. What is technology? It is usually mentioned together with science.  What is the difference between them? In my opinion, science is a question about why, and technology is a question about how. Technology is a subject about how transform knowledge into productivity. Human progress is related with the development of productivity. So although  there are many harmful benefits about technology, everyone can not leave it. 

Today I want to discuss whether humans should exploit nuclear power. There is a great debate about nuclear power all over the world. Firstly，I think everyone who participate in this argument should clearly what is nuclear power? If you search nuclear power in Wikipedia, you will get the answer like this: Nuclear power, 
or nuclear energy, is the use of exothermic nuclear processes, to generate useful heat and electricity.(Wikipedia.com)

There is a great debate about nuclear power all over the world. 

There some benefits of nuclear power.

1.Nuclear power does not cause air pollution. 

2.Nuclear power does not produce CO2 which increase the greenhouse effect.

3.Nuclear fuels energy density are millions of times than fossil fuels. 

4.Nuclear power generation fuel cost is very low.

5,Nuclear power is the most secure way of generating in fact. In the process of coal mining, oil and gas,there are tens of thousands of practitioners has been killed.in the explosion and collapse of the accident.

There some harmful benefits of nuclear power.

1.Waste produced by nuclear power plants is radioactive.

2.The thermal efficiency of nuclear power plants is low, that will cause the heat pollution.

3.Nuclear power plant investment cost is too big, the financial risk of power company is too high.

4.Nuclear power plants is not appropriate to do with the load of the peak and off-peak operation.

5.To build a nuclear power plant is easy cause political disputes.

6.If released radioactive material into the environment in the accident, it will cause harm to the ecological and people.
