Transcript of Nuclear Power

Nuclear Power Jin Ho Lee 10W Nuclear Power Plant Nuclear energy is generated inside a plant called a reactor and cause of this it got the name of nuclear power plant. The source to generate the power is the heat that is produced by a controlled nuclear fission chain reaction, such as uranium and plutonium. This reaction is to split uranium and plutonium by neutron being struck. The results of the fission reaction of these large atoms are the creation of new and smaller atoms as byproducts, radiation and more neutrons. Then the neutrons speed out and decay other uranium and plutonium atoms and create a chain reaction. An example of nuclear fission process is the reaction of .
This chain reaction is controlled by neutron moderators which vary depending on the design of the reactor. Finally the chain reaction generates heat and converts water in to steam. Then the steam is used to turn the blades of a turbine which will run the generator. Benefit of Using Nuclear Power There are a lot of benefits for using nuclear power. However, considering all the part of using nuclear power is seems to look like there also limitation of using nuclear power. First of all, nuclear fuel contains about 2.3 million times as much energy as coal and it cost only quarter of those sources. It is also considered as clean since it does not release chemical pollutants or particulates into the air or water. However, it does release a small amount of radiation at all times and this could lead to a massive accident. The worst type of accident could be core meltdown, witch it is results from withdrawing the control too far, and causing the fission reaction in the fuel rods to speed up to where enough heat is created that the core can literally melt its way out of the containment structure, and finally it spreads a lot of radiation into the atmosphere. Another advantage of nuclear power is that Uranium is available in plentiful quantities and plutonium is created as a byproduct of the nuclear fission process. Therefore, it shows that there are benefits for using nuclear power, and there are also limitations of using nuclear power. Japan List of Nuclear Power Plants in Japan Goverment and People's view of using Nuclear power It seems to look like in Japan that the goverments wants more nuclear power plant to be built. Since it shows that Government are funding the nuclear power development. In addition, the goverment have announced that they will rely on nuclear energy to achieve green house gas emission reduction goals set by the Kyoto Protocol. witch this will be holded for ten years and have said to increase the nuclear power generation by about 30%. Moreover, they have announced that if this goal success they will reduce the price of oil, coal, and tax. However, people living in the Japan are bit scared of increasing the nuclear power plant. Since they still remember the accident that have happened in Japan. South Korea Power reactors operating in South Korea Reactor Type Net capacity Commercial

impact on Social, economic, political, environmental, cultural and ethical As nuclear power are being used in world wide, making the nuclear power have effected many things in our daily living. It first have impacted social by making countries that has nuclear power to trade with other countires who does not have nuclear power plant or has lack of nuclear power. By doing this it is making countries to cooperate each other. In addition to economic, it have made some countries taxes low and made some countries to have lower price for energy. However the use of nuclear energy is still causing problems toward environment. For example, in Japan air pollution from power plant emissions results in acid rain. Moreover, acidification of lakes and reservoirs degrading water quality and threatening aquatic life. This could happen in many countries because there cultural is different and they are not ethical enough witch they gather more nuclear power than the amount they need.

Reflection As I have researched two countries witch uses nuclear power, I have noticed that nuclear power could be used effectively. However there are still problem witch Japan is having too much of nuclear power plant compare to the population and people in Japan. It is good things to stop the greenhouse gas emission, but still using nuclear power too much will also produce radio active witch it could effect environment. Compared to number of nuclear power plant they have, Korea have just enough power plant for people. I also thinks that if the nuclear power does not effect any to the environment, it could have been the best source of energy. Thank You
