Firstly, the atomic incidents of Three Mile Island in Pennsylvania and Chernobyl in Russia are often mentioned as examples for nuclear plants being unsafe. In both cases failures of workers led to a meltdown in the reactors and increased radiation in the surrounding area (Henderson 12-17). And as the recent disaster in Japan shows, a nuclear crisis cannot only be caused by human mishaps, but also by unpredictable and untamable natural hazards. Consequently, nuclear crises cannot be predicted or prevented completely. Nuclear plants are, furthermore, considered uneconomical because in the eighties the construction costs of nuclear plants were underestimated and exceeded the estimation by $100 billion (Henderson 103). Therefore, the nuclear power opponents are arguing that nuclear power is burdening the American economy unnecessarily. According to the nuclear physicist Jeff Eerkens, antinuclear groups are also claiming that nuclear power is not necessary for the future since renewable energy sources, such as solar, wind, hydro, and geothermal power will be providing sufficient energy for the United States, and are at the same time much cheaper than the costly nuclear power plants (Eerkens 20). Over all, opponents consider nuclear power to risky and inefficient to “deserve further support from U.S. taxpayers” (Henderson 104).
Disposal of the high level nuclear waste that comes from nuclear power plants continues to be a big problem. It has been challenging and costly to find safe ways to store this waste. According to a report from the U.S National Academy of Sciences, it will take 3 million years for radioactive waste stored in the U.S. as of 1983 to decay to background levels (thinkquest.org). Who wants this amount of waste stored in the environment where they live? Currently in the U.S. nuclear power plants produce 3,000 tons of this high level waste each year (thinkquest.org). If nuclear power continues to be produced, this amount of waste will only continue to increase, causing a bigger dilemma as to what to do with the waste. As the waste is removed from the plant it still contains a high level of radiation. Exposure to radiation whether it occurs in the moving process or leakage from storage not only has a negative impact on the environment but also can pose a major health threat to humans. Based on the level of exposure, symptoms to humans can range from nausea and headaches to damage of nerve cells, loss of white blood cells and even death (think .org). The potential risk of exposure is not worth human life.
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.
You may not know much about nuclear power, you may not know anything at all but most importantly you may not know how dangerous it is. I am going to take a look back at Chernobyl and show you just how dangerous it can be.
For years, many scientists, environmentalists, and energy experts have been studying how human’s creation and use of energy has impacted our environment. These experts have discovered some troubling facts. Most of our country’s energy is created from burning fossil fuels that pollute our atmosphere, contribute to global warming, and thus threaten the future of our planet. But there’s a safe and effective solution to this problem: nuclear power. Nuclear power should be used more in the United States to create clean power that doesn’t pollute our environment, in order to help combat climate change.
Nuclear power plants are a safe, clean and reliable source of energy production. They are uniquely qualified to meet the growing demand for energy in the USA.
On Wednesday, March 28, 1979, around 4 a.m., there was a failure in the water pumps at the Three Mile Island in Middletown, Pennsylvania. This led to a partial meltdown of a nuclear power plant. The Environmental Protection Agency (EPA), the Department of Health, Education and Welfare (now Health and Human Services), the Department of Energy, and the Commonwealth of Pennsylvania all conducted particular studies of the radiological consequences of the accident. Approximately two million people were estimated to have received an average of one millirem of radiation, and there was a maximum dose to a person who was at the site of 100 millirem (“Backgrounder”). To put this into perspective, an exposure from a single chest X-ray is two to six millirem (“Doses”). However, this put fear into the minds of politicians and others all across the country. What the people do not know, though, is nuclear is better. Instead of using fossil-fuels and wind power, America ought to switch to nuclear energy to power the country because it is safer, cleaner, less expensive, and more reliable than the current ways of producing energy
Nuclear energy powers just about 20% of the United States. The United States holds only 100 of the reactors out of the 400 that are in the world. Even though a reactor does not put any pollutants in the air it still creates nuclear waste. Nuclear fission use uranium and plutonium and turn them into smaller atoms. When splitting atoms you have to hit it with a neutron. When split several atoms can be split like a chain reaction.
In a nuclear power reactor, the energy released is used as heat to make steam to generate electricity .All matter is composed of elements. The important elements for our discussion of nuclear energy are uranium, plutonium, carbon and hydrogen. Uranium and plutonium are involved in nuclear energy production, and carbon and hydrogen are the main elements in conventional fuels like coal, oil and natural gas. You can find nuclear energy in the United States has more than 100 reactors, although it creates most of its electricity from fossil fuels and hydroelectric energy. Nations such as Lithuania, France, and Slovakia create almost all of their electricity from nuclear power plants. Uranium is the fuel most widely used to produce nuclear energy. There is two kinds of nuclear power plants Fission reactors can be divided roughly into two classes, depending on the energy of the neutrons that sustain the fission chain reaction: Thermal reactors the most common type of nuclear reactor use slowed or thermal neutrons to keep up the fission of their fuel. In my opinion i think Nuclear power plants are safer and a lot more beneficial than any other energy
Nuclear power plants do not emit the harmful green house gases and other negative by-products associated with the more conventional systems fuelled by coal and natural gas. Nuclear power plants use nuclear reactions to drive their generators. The reactions produce extreme amounts of heat that must be managed. Most
These accidents were chosen because they constitute worst yet valuable examples of what can – and, occasionally, does – go wrong in the nuclear power production realm, and because they shape our understanding of the caused harm. They also embrace a thirty-five year period, during which nuclear power underwent significant regulatory development worldwide, aiming to address growing concerns with respect to short- and long-term effects of such disasters on human health, environmental, social, and economic factors.
According to Community Science Action Guides, nuclear power plants are cheaper to run, require smaller area than its competitors, and produce the most energy than environmental impact ratio. Nuclear power plants should be used in the United States based on three reasons: spatial area/location of use, cost efficiency, and environment friendly. To prove that nuclear power plants is a better energy solution, it will be compared to other major energy resources such as wind turbines, solar farms, dams, and biomass technologies.
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.
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.
With any large energy producing facility there are risks. The truth is that accidents do happen at nuclear power plants and at other facilities all the time. An example of this was the accident at Three Mile Island in Pennsylvania where there was a partial meltdown in March 1979. More recently was the worst nuclear accident at Chernobyl. Statistical data for 1995, released by the International Atomic Energy Agency early in 1996, indicated that there were a total of 437 operational nuclear power stations in 31 countries with years of experience. Chernobyl was the only plant that injured the public. Thus, judging by the data, that is a good record for a source of energy.
