As humans, we have nearly mastered the art of nuclear fission. Currently, nuclear energy plants are responsible for about three-quarters of carbon free energy. This statistic shows that solar and wind power is used so minimally compared to nuclear energy. It releases little to no greenhouse gasses so environmentalists’ minds can be at ease. Using nuclear energy would not accelerate climate change because it does not affect the earth when it is being made or released.
Uranium, Uranium-235 is the preferred isotope, is used because it under goes fission naturally and at a slow rate. The energy that is emitted from the Uranium is then used to heat up water. The water then turns into steam and the steam pushes a turbine that spins a generator to produce electricity. That is the basics on how a nuclear reactor works. This method is better than traditional coal power plants because it emits minimal levels of carbon dioxide into the air.
Also the quantity of waste produced by nuclear power plants is rather small which makes the chance of diseases for humans less. On the other hand, nuclear power plants have several disadvantages. One is that by using nuclear power, poisonous waste is produced which is in some cases extremely radioactive and can cause sicknesses and diseases like cance... ... middle of paper ... ...ugh this topic is controversial and many things can be discussed, nuclear power is necessary to humans since it provides essential energy for our every day lives. The risk of getting cancer is more or less low, so the usage of nuclear power for providing energy can be seen as not too harmful for humans. That is why nuclear power should be used to provide energy.
Nuclear energy is an alternative to using fossil fuels. Although nuclear energy is also nonrenewable, it has a much lower amount of air pollution, as well as a lower risk of affecting the climate through global warming. There are three main kinds of nuclear energy, nuclear fusion, nuclear fission, and radioactive decay. This report will explain how nuclear fusion works, as well as explaining the advantages and disadvantages of nuclear fusion. Nuclear fusion occurs when two or more elements are fused together.
The nuclear waste is unlikely to expose to people, because there are guards who will protect the waste in where it is stored at. Lastly, there are some bad things about nuclear energy, but it is not much compared to the good things. In conclusion, nuclear energy is an efficient source to produce electricity. With nuclear energy, over million tons of carbon dioxide are reduced in the U.S. Nuclear energy also help reduce the amount of land use to produce electricity and get more free land for other purposes. According to the low accident rate of nuclear energy, nuclear power plants would be consider as a safe way to produce electricity.
Many scientists are searching for other forms of energy. Nonreplicable energy sources such as solar energy are being explored; however, these methods are not highly developed and are very expensive. Nuclear energy, therefore, appears to be the best alternative since it is cheaper and because it doesn't emit carbon dioxide into the atmosphere like the combustion of the fossil fuels do. Nuclear energy comes from the fission of uranium, plutonium, or thorium or the fusion of hydrogen into helium. “Fission is defined as the splitting of atomic nuclei spontaneously or because of the absorption of a nucleus.” (Source 1) It produces radioactivity in the form of heat, smaller nuclei, and neutrons.
Nuclear power plants cause radiation which is dangerous to people and the environment, “it can be dangerous. If radiation leaks, it can be deadly. If the reaction gets out of control, the process can be explosive” (Reilly 62). Controlling of the reactors are very important, they need to be kept under control to prevent any meltdowns from happening. There has been meltdowns that have caused many disasters to the place where it has happened.
If there is one thing that I have learned in this course it is that our contribution to our environment plays an extremely crucial role in global warming and what our environment will be like in the future for not only the current generation, but for generations to come. To go off my point of picking nuclear power versus coal power, nuclear power has significantly less of an impact on our country than coal. Nuclear power does not contribute carbon dioxide emissions as readily as coal does leaving it far safer for our environment. Another reason that I chose nuclear power over coal power is the idea that nuclear power is extremely reliable and will last longer than fossil fuels. Of course, coal has a significant amount of reserves on hand today, but eventually the world will run out coal and we will be left to find other sources to make our energy from.
The difference of a nuclear power plant to other power plants is in the process on how the heat is created. Other power plants that run on fossil fuels, burn oil, coal or natural gases generate heat. While in a nuclear power plant, it generates heat by splitting the atoms of certain elements like uranium. Nuclear energy requires a large capital for emergencies, storage systems and containment but it has a lot of benefits and the best energy source in the long run. With the depleting sources, nuclear energy is the only energy source that can satisfy global demand, effectively replace fossil fuels and it is more sustainable than other energy sources.
One downside to nuclear energy is that even though it does not produce any greenhouse gases, we would eventually run out of uranium, which is why it is not considered a renewable resource1. Another downside is that the use of nuclear facilities and energy do produce radiation. The radiation, however, is released in very tiny levels that are regulated in order to keep people and their lives safe. The power plants produce radioactive liquid waste and gases during use, but the plants have tanks that are used to store those gases and liquids until their radioactive levels have dropped and are safe to be treated and release in a safe fashion1. However, if in the event of a disaster, in which the radiation is somehow release in a larger amount, the effects of nearby life would be devastating.
