Element 92: A Misunderstood Energy Source
In 1939, Albert Einstein wrote a letter to President Franklin D. Roosevelt, saying, "the element uranium may be turned into a new and important source of energy in the immediate future." Even then, the potential to harness nuclear power as an energy source was recognized. Six years later, the atomic bomb was dropped on Hiroshima and Nagasaki, killing an estimated two-hundred thousand people and forever linking the word 'nuclear ' with death and destruction (Danzer 790). Since that day, nuclear power has been trying to throw off the shadow of its dark beginnings. However, there are numerous people to this day that remain wary of this particular power source. Often safety is called into question, citing major disasters as reasons to forgo its use. Efficiency and cost are also brought up, questioning whether nuclear power is a better alternative financially. Many people fail to realize there is more to nuclear energy than the what bedtime horror stories reveal. Nuclear power is a safe and effective energy source that should be utilized more than it is now.
Nuclear power is achieved through fission; the splitting of an atom. Usually, the atom is uranium, the ninety-second element on the periodic table. One of the heavier elements, uranium is unstable and produces an extreme amount of energy when split (Reynoldson 5). Other elements like plutonium can also be used, but plutonium is very rare which results in the majority of nuclear
On contrast, opponents hold different conceptions, they do not regard nuclear energy as a green and clean source of energy. According to Ross(2007), a news director for the National Urban League, fuel rods at every nuclear plant leak radioactive and harmful gases to atmosphere, and it is collectively releasing millions of curies annually. As a matter of fact, the essential raw material for nuclear nuclear power is uranium, which is a dangerous radioactive element. Opponents also claims that uranium tailing which is byproduct of the procession of getting energy are being inappropriately disposed, which make the situation even worse. On the other hand, after the tragedies of nuclear energy in Chernobyl, three mile island and other district, some people have become more and more impregnable to believe the nuclear energy is dangerous. Dr.
Nuclear energy is gathered by the process of splitting uranium atoms. By splitting these atoms, there is some mass loss, and this mass can then be used as energy. This process is called fission. The heat from this fission is used to turn water into steam, and this steam turns the turbine generator in a reactor, which produces energy. Nuclear power plants have many advantages when compared to other renewable energy sources.
Nuclear energy is the energy that is released during nuclear fission or fusion also called a nuclear reaction. It is used to generate electricity energy is produced when a nucleus absorbs a neutron and splits into two lighter nuclei. The atoms consist of an electron cloud and a nucleus. (nuclearinfo.net)
1b/process. “How do we harvest this lost energy,” you might be wondering? Well, nuclear energy receives its power from the fission, or splitting, of atoms in very dense radioactive metals. Once one atom is split, the halves separate into 2 or more less dense atoms, and remaining neutrons can be shot out at high velocities. If these neutrons slam into another atom and are captured by it, that atom has a chance that it too will undergo fission. This cycle of splitting atoms is a chain reaction. Nuclear fission requires power to start the chain reaction, and it needs a certain amount of Uranium, called a critical mass, before this chain reaction can support itself and create excess energy. This excess energy is released as heat, usually into water. This changes the water into steam and is used to turn turbines to produce electricity. According to an article written by the U.S. Dept. of Energy, the first successful attempt at a self-sustaining nuclear reactor was on December 2nd, 1942.
Nuclear energy is created by splitting the nucleus of a uranium atom by firing a neutron into the atom’s nucleus, this in turn splits the Uranium into 2 different substances. Whilst splitting the atom it creates enormous amounts of heat energy which we use to boil water. Once the water reaches its
On August 6 and August 9, 1945 in the Japanese cities of Hiroshima and Nagasaki, survival solely depended on being in the right place at the right time. When American planes dropped the atomic bombs onto the cities of Japan, no one knew what exactly would be the effect of this powerful nuclear weapon. However even years later, innocent Japanese citizens suffer from the experience of these traumatic days during World War II. Despite the horrors, critical information and research was drawn from the development of the atomic bomb and scientists have discovered that there are many benefits of using nuclear energy, in a peaceful manner, in our world as opposed to using other energy sources, such as coal or gas. For example, nuclear energy has
Nuclear power, the type of energy that sits on the edge of humanity’s greatest hopes, and its darkest fears. With a country such as the United States continuing to expand its industry, housing, agriculture and commercial buildings there is a need for more and more energy each year. Nuclear power is one of the many ways the United States gets its energy. Nevertheless, it is one of the most controversial means of energy production. The main concern with nuclear energy is the nuclear waste that is produced along with it. The potential health and environmental risks posed by nuclear waste is what truly scares some of the American public. Therefore, is the amount of energy output by nuclear power plants outweigh the potential risks that nuclear waste can have on human health and the environment? Nuclear power plants should be kept as a means of generating energy for the United States, however, transportation and storage of nuclear waste needs to continuously be checked for safer alternatives.
Even though nuclear power plants threaten the health and safety of many people, nuclear energy is being used in other ways as well, which may be even more dangerous. In 1945, the United States dropped an atomic bomb on Hiroshima, Japan, in order to end World War II. This event was the only time a nuclear weapon was used in the history. During the first two to four months, approximately 90,000 to 166,000 people died as a result. Wilfred Burchett quoted, “When you arrive in Hiroshima, you can look around and for 25 and perhaps 30 square miles you can neither see hardly a building nor a standing human. All of them are collapsed on the ground.” Yet, having seen the destructive effects of nuclear weapons, the United States currently still owns more than 7000 nuclear weapons, in which half of them could be launched in less than ten minutes. Russia is believed to be a holder of the same number or more nuclear weapons as well. The United States and Russia are the two countries with the most nuclear weapons, but in total, the number adds up to around 19,000 worldwide. Many people do not give a thought about this dangerous situation, since these weapons are
Nuclear energy is the energy released by a nuclear reaction, it uses fuel made from mined and processed uranium to generate heat and electricity. It is the world’s largest emission free energy source. Nuclear energy also has the lowest impact on the environment than other energy sources. But it can still be very harmful because of the radiation is causes and the radioactive waste it produces. Radioactive wastes are the ruins of nuclear materials that are used in providing nuclear energy. These wastes contain high levels of radiation that can be very hazardous to humans and the environment. Some people accept and support the idea of using nuclear energy and others don’t. In the following paragraphs, some major nuclear accidents and the public acceptance of nuclear energy will be discussed.
Nuclear power was the world’s fastest growing form of energy in the 1990’s. However, presently it is the second slowest growing worldwide. Considering that nuclear power accounts for eleven percent of the world’s energy supply, one must ask what happened [Nuclear Power]. Why is it that the growth of nuclear power has almost completely stalled? The simple answer is that after meltdowns such as Three Mile Island and Chernobyl, many people are afraid of nuclear power plants, which causes great opposition to the expansion of the industry. Unfortunately, most people are not well informed about nuclear energy; many do not take the time to view its positives and negatives.
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.
Do you know the repercussions for using nuclear energy? Do you know how much it costs to fund nuclear energy? Do you know what a nuclear accident could do to thousands of people? Nuclear energy was first used in a peaceful manner, but in August 6, 1946, a tragic event called Hiroshima happened. (The History of Nuclear Energy 1985) Nuclear energy should not be used because it can cause a negative impact on all living beings, it is an expensive way to produce energy, and nuclear energy can cause great tragedies.
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.
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
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.
