Nuclear Power

Good or Bad ?

Summary I) Introduction II) Advantages of Nuclear power A) Economic benefits B) Others advantages III) Desadvantages of Nuclear power A) Environmental drawbacks B) Economic disadvantages IV) Conclusion

Introduction Important energy source in the world Particularly in France (most nuclear power per person) Nuclear energy seems to be an advantage widespread use may raise problems ? Dangerous energy ?

I) the history of nuclear energy Research on radioactivity at the origin of the discovery of nuclear energy discovered in 1938 by Hahn and Strassmann 1951 : first civilian nuclear reactor (United States) 1956 : the first reactor to emerge in France in Marcoule Between 1970 and 1990, Generation II reactor is deployed.

II) Advantages of Nuclear power Differenciate advantages in two parts

a) Economic benefits major economic benefit. Offers many jobs electricity is mainly supplied by nuclear quantities of electricity supplied by nuclear is not comparable to other (wind turbine, water dams,..)

b) Others advantages Natural resources of the planet (gas, coal, oil in particular) are increasingly rare. nuclear saves resources. No need of large space. Nuclear plants do not emit CO2 Nuclear power contributes to maintaining a high scientific level on the territory.

III) Desadvantages of Nuclear power Like the advantges, separate into two parts.

a) Environmental drawbacks Waste storage result some problems Waste treatment does not completely suprime risks contaminated water which cools the central (lake, …) Exposure to radioactive materials can be deadly (Hiroshima, Tchernobyl, Fukushima, …) life of a radioactive element very long

b) Economic disadvantages Nuclear energy is extremely expensive. (maintenance and storage)

Conclusion One nuclear central can feeds several city Large economical benefits If not control, very Dangerous Nuclear power essential but scares people.
