Nuclear Energy : Nuclear Power Essay

Nuclear energy is the world's largest source of emission-free energy. Nuclear power plants produce no controlled air pollutants, such as sulfur and particulates, or greenhouse gases. "Renewables" like solar, wind and biomass can help. But only nuclear power offers clean, environmentally friendly energy on a massive scale. The use of nuclear energy in place of other energy sources helps to keep the air clean, preserve the Earth's climate, avoid ground-level ozone formation and prevent acid rain. “Currently, there are 103 commercial nuclear power plants producing electricity in the United States, located at 64 sites in 31 states. They are, on average, 24 years old, and

Presently, nuclear fusion and nuclear fission are being studied, and even used in some countries as a power generator. The enormous energy produced by nuclear fission and fusion could light up a big city for a hundred years or more and we do not have to worry about it polluting our environment because nuclear energy is a green energy. Moreover, in a long term, the cost to generate power using nuclear is far less than the cost of generating power using fossil fuel.

Nuclear power is harnessed from the energy retained inside of an atom’s nucleus. This energy bindes the atom together and, when released, can be used to produce electricity. In order for this energy to be released, however, it must be subjected to either nuclear fusion, the combination of several atoms to form one larger atom, or to nuclear fission, the division of larger atoms into several smaller atoms. Nuclear power plants, first introduced in 1954, use this second method in the production of electricity. Inside of a nuclear power plant, uranium atoms are split and their nuclear energy released, creating the heat necessary to produce the steam that powers turbine generators and create electricity. Nuclear energy is often referred to as a “clean” energy source because, unlike fossil fuels, its production does not result in the generation of greenhouse gases, such as carbon dioxide, methane, sulfur dioxide, and nitrogen oxides. Many endorse the use of nuclear energy because it is efficient, providing large amounts of energy in exchange for small amounts of fuel, reliable, as it can be produced almost all day and night, year round, and affordable, costing about 2.4 cents per kilowatt-hour in 2012 compared to fossil fuels, which cost about 3.27 cents per kilowatt-hour in 2012. However, the use of nuclear power also has several significant disadvantages. Its main downside lies in the threats nuclear power plants present in the forms of radioactive waste and nuclear meltdowns.

Nuclear energy was likewise discovered to be useful in naval tactics and in sourcing electricity. As technology has significantly advanced and knowledge has expanded beyond measures, the realm of nuclear engineering has indeed achieved scientific milestones. In practice of modern times, nuclear energy is manufactured within power plants, capable of supporting an outstanding amount of electricity (World Nuclear Association). However, this limited method of energy production is thought to be dangerous. Nuclear engineering is certainly one complex subject and is foreign to the majority of the world population. Within a nuclear power plant, reactors are employed to force uranium ions to undergo the process of nuclear fission; nuclear fission is the separation of atoms, the smallest unit of matter. This splitting of uranium ions releases energy, thus, producing usable heat. Heat is crucial to not only nuclear energy production; rather, heat is necessary in all power plants. Such will then become the steam that gyrates turbines. These turbines are coupled with electromagnets which, finally, yield electricity (How Nuclear Reactors Work). One foremost flaw of nuclear power is the consequential radioactive waste that must be monitored for a long while following disposal. Nevertheless, as resources upon this planet are surely depleting, original forms of energy production are mandatory. In consideration of such, nuclear power plants have proved to be both efficient

One nuclear power plant with a footprint of one square mile provides the energy equivalent of 20 square miles of solar panels, 1200 windmills, or the entire Hoover Dam. All of this power comes without any greenhouse gas emission although they do produce nuclear waste. Unfortunately most nuclear energy comes at the risk of a potential nuclear meltdown like Chernobyl or Fukushima. While nuclear meltdowns may be rare there does is a potential nuclear fuel that promises even cheaper energy, with no chance of a nuclear meltdown, and produces significantly less nuclear waste. Thorium is a radioactive element close to uranium on the periodic table, named after the

These issues combine to place an unfavorable light on the potential of nuclear power. Nuclear fission, however, is not the only source of nuclear power. Nuclear fusion is another method which offers the potential to combat some of the ailments of nuclear fission in addition to providing long lasting power. Nuclear fusion offers several benefits to energy industry. Among the benefits of fusion power is that fusion fuel is readily available, power produced is reliable, has a low environmental impact, does not produce fissile materials, and carries the same terror risk as conventional fossil fuel plants [6]. To understand why some of these benefits are true, an understanding of the science behind nuclear fusion is necessary.To start, nuclear reactions involve the protons and neutrons contained in the nucleus of an atom. This is different from how chemical reactions, like the burning of fossil fuels, involve the electrons of an atom. In nuclear fission reactions, heavier elements are torn apart. The resulting products are more stable than the reactant, and energy is

The disastrous meltdowns that cause whole cities to become uninhabitable, as well as leaving families homeless and laborers without jobs, have defined the negative perspective of what people see in nuclear power. However, even after such catastrophes, the pure raw energy output makes nuclear power essential for the future of the human race. As time passes, the world’s energy usage has grown an increasingly massive size every year due to the consumption swell of energy. Despite nuclear plants being a heavily controversial topic internationally, its advantages are very well recognized and it’s causing nuclear plants to slowly become the basis of our growing society.

In 1939, the discovery of nuclear fission unlocked the potential of an entirely different source of power. The utilization of internal energy contained in the atomic nucleus has provided a major solution to present and future power source needs by turning away from fossil fuels such as coal, oil and natural gas and currently encompass three-fourth of world’s energy requirements to cleaner alternatives such as nuclear power and renewables.

The world as we know today is dependent on energy. The options we have currently enable us to produce energy economically but at a cost to the environment. As fossil fuel source will be diminishing over time, other alternatives will be needed. An alternative that is presently utilized is nuclear energy. Nuclear energy is currently the most efficacious energy source. Every time the word ‘nuclear’ is mentioned, the first thought that people have is the devastating effects of nuclear energy. Granting it does come with its drawbacks; this form of energy emits far less pollution than conventional power plants. Even though certain disadvantages of nuclear energy are devastating, the advantages contain even greater rewards.

Just five pounds of plutonium, a component of nuclear waste, is enough to make a

Nuclear power is generated from the energy that is released from a heavy nucleus into a lighter, more stable nuclei. The heat produced is used to boil water which drives a steam turbine to generate electricity. This chain reaction process is also called fission. A key element to fuel nuclear plant is uranium. Uranium is considered to be a nonrenewable energy source, even though it is a common metal found in rocks worldwide. U-235 is most commonly used in plants because its atoms are easily split apart. To extract U-235 uranium ore is mined; for the United States, this element is found in the

abandoned. All three topics are dealt with in fusion, that is why it is such a

Global demand and consumption of energy is at an all time high; the world needs a safe, efficient, clean, and high producing source of energy production. The solution is something we already use for energy production, Nuclear power. From the beginning of nuclear energy there has been concerns over the safety of the power plants and its impact on the environment. With climate change and more accurate information on nuclear power the tide is shifting in its favor. This paper will explore the positives of nuclear power, political change on nuclear power, safety of the energy source and new technologies associated with the nuclear power process. Most importantly are the risks associated with nuclear power worth it? Research suggests that nuclear power is safer now more than ever and has less of an impact on the environment than coal or oil. Public support and misconceptions over the years have been up and down due to political agendas and those who are misinformed about nuclear power. Individuals who are involved in the energy field are in favor of nuclear power and building more plants with newer technology.

The use of nuclear energy is a big topic for debate. Many countries have fully embraced it while others, such as the U. S., haven’t. Nuclear energy is feared for its danger and scorned because of its wastes. On the other hand, nuclear energy does have some pros like cheaper cost of energy and environmentally safe. Reactor breeders show great promise in nuclear waste, but are it enough to convince the nation?
