Nuclear Energy

Extracts from this document...

Introduction

NUCLEAR ENERGY Uranium is mined from the earth and is formed into small pellets, and then placed in long rods. Bunches of these rods are kept in a severely restricted environment called a reactor, where the nuclear reaction opens up. The reaction starts when nuclei of the uranium atoms are attacked with neutrons and this causes the nuclei to separate. This process is called fission. When the nuclei separate, some of the energy turns into heat, and the rest results in radiation. The heat is then put to work, turning water into steam, which drives a turbine, which spins a generator and produces electricity. ...read more.

Middle

Coal and oil burning plants pollute the air around us; conversely, well-operated nuclear power plants do not discharge pollutants into the environment, making it enhanced and safer. There are many disadvantages of nuclear energy. Many countries have enough nuclear bombs to eliminate everyone on this earth. Russia and the United States, being the most power have about 50,000 nuclear weapons between them. Nuclear explosions produce radiation, which harms the cells of the body. Also, illness can hit people years after their exposure to nuclear radiation. In a meltdown, the fission reaction goes out of control, thus creating a nuclear explosion and the release of massive radiation. ...read more.

Conclusion

Also, nuclear reactors have waste disposal problems, which produce nuclear waste products that release dangerous radiation. Due to the fact that they could kill people who touch them, they cannot be disposed like usual garbage. At this time, many nuclear wastes are kept in special cooling pools at the nuclear reactors. The United States plans to move its nuclear waste to a remote underground dump by the year 2010. In 1957, at a dump site in Russia's Ural Mountains, buried nuclear wastes strangely exploded, killing a lot of people. Nuclear reactors only last for about forty to fifty years. http://www.nei.org/scienceclub/4yourclassproject/4ycp_hownucenergyworks.html http://www.nvnpp.vrn.ru/en/about/advantages.html http://library.thinkquest.org/3471/nuclear_energy.html ...read more.

  1. Alternatives to fossil fuels

    Compared with other alternatives, nuclear power can produce bigger energy. Studies show that the total annual solar energy input to the earth is more than 15,000 times as great as the earth current yearly use of fossil and nuclear fuels.

  2. The world would be a better place without nuclear energy. What do we use ...

    It is possible that a country is enriching uranium to use in your nuclear reactors but the same uranium can also be to build an A-bomb. There is no way to tell for sure if a country has only peaceful uses for its nuclear programme.
