Introduction
A nuclear energy plant is a power station that produces electricity from nuclear reactions. Like other conventional thermal power stations, nuclear power plants heat up water into steam that is then used to drive power generators. The nuclear reactions involve extremely radioactive elements that contain a lot of energy. These are atoms with an unstable nucleus that continually emit small packets of energy called radiation in an attempt to attain a stable configuration (Timberlake, 2013). When such atoms are bombarded with a neutron, they easily split in a process called fission. Since Uranium is a large atom, the atomic force that holds it together is relatively weak, making it a suitable atom for fission in nuclear reactors.

Since Uranium is a highly radioactive element, it is highly dangerous to the human body as is evidenced by the Chernobyl nuclear accident in 1986 (Timberlake, 2013). This makes the costs of handling it at any stage quite expensive. There has been a long-standing debate on the safety, environmental and economic effects of nuclear power plants. This paper summarizes various literatures by a number of nuclear energy critics, most notably Benjamin Sovacool, a Social Sciences professor and a renowned scholar mainly due to his critical stand on nuclear energy. An analysis and a response follow the literature review
Literature Review
1. Economics
In his book, “Contesting the Future of Nuclear Power”, Benjamin Sovacool discusses that the economics of starting and operating a nuclear power plant. He compares it to those of other sources of electricity such as the renewable sources of energy which consist of wind, water and sunlight (WWS) and other non-renewable sources such as coal and other fossil fuels. Nuclear power plants inherently have a high initial capital budget for the construction of the plant. The initial investment may contribute between 70% and 80% of the cost of electricity (Du & Parsons, 2009). Cost projections thus need to take into
In this section we analyze various social impacts associated with the establishment and operation of nuclear power plants. The impacts of nuclear plants on nearby communities and people living there have been a controversial issue since long time. Nuclear power generation and utilization has several impacts on society which includes real estate, property values, employment, taxes, social services, physical and mental health, economic development and cultural parameters, etc.
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.
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).
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 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.
Although it was predicted that one day nuclear power would make electricity “too cheap to meter”, instead now it is “too expensive too finance” (“Cheap Dreams, Expensive Realities,” n.d., para.2). Although nuclear industry says that nuclear power is the cheapest compared to other methods of power, costs of nuclear power have been underestimated by almost a factor of three (Caldicott, 2006 p. 19). This is because a lot of costs related to nuclear power have not been accurately reflected in the figures shown to public, such as cost for the total nuclear fuel cycle, construction and running costs. Waste disposal and decommissioning are other expenses related to nuclear power that are ignored when figuring out the estimated cost of nuclear power (Karson, p. 26). Many groups argue that the cost of nuclear generation is at least three times the figure provided by the British Nuclear Fuels (McLeish, p. 36). Another reason, nuclear power costs are underestimated is due costs of new technology needed for the power plant are not taken in to account. Delay in construction is also an unnoticed expense (McLesih, 9. 37). It is unlikely to take the full cost of nuclear power into account. It is hard to claim that nuclear power is the more competitive price energy source compared to other energy sources because of its many hidden
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.
Secondly, the book points out that the collective cost of nuclear energy production is not economical, which is unfounded. Even under favorable assumptions for wind and solar energy plants, such as an increase in capacity factor, it is shown that the total net benefits of a nuclear plant (at $804,763 per MW per year) clearly outweighs wind plant (at $283,311 per MW per year) and solar plant (at $113,349 per MW per year).6 This implies that the benefits a nuclear plant derived from reducing carbon emissions and having a high capacity factor clearly outweighs the insurance and operating costs of a nuclear
William Shakespeare’s play, “Macbeth”, is a widely renowned and well-known piece of literature. The play first starts of telling how Macbeth, a great fighter, with his strength and great skill, helps to win the war. Soon after three witches tell Macbeth of a prophecy that he will become the Thane of Cawdor, then he will become the king. The prophecy comes true when King Duncan names Macbeth the Thane of Cawdor, and Macbeth realizes that the throne could be his. Soon after, Macbeth and Lady Macbeth murder King Duncan and this one choice changes everything.
As each year passes, more and more electricity will be made as a result of increased nuclear power plants around the world. The economic benefits of nuclear energy are equally advantageous as the environmental aspects.
In class we defined imagery as creating an image with words, in other words imagery is when the author paints a picture for readers through words. The word imagery is associated with mental pictures. It means to use figurative language to represent objects, actions, and ideas in a way that it magnetizes our physical senses.
Nuclear fission is a reaction in which heavy nuclei, such as Uranium and Plutonium, are broken into smaller nuclei releasing heat, which is transformed into another form of energy such as, mechanical or electrical. For a long time people have been using nuclear fission as an efficient and sustainable source of energy. However, the use of this form of energy is associated with a unique set of consequences including environmental, social and ethical. In this paper I will discuss nuclear energy and its impact on the environment.
Low costs. The initial construction costs of nuclear power plants are large. When the power plants first have been built, we are left with the costs to enrich and process the nuclear fuel, control and get rid of nuclear waste, as well as the maintenance of the plant. The reason this is under advantages is that nuclear energy is cost-competitive. Generating electricity in nuclear reactors is cheaper than electricity generating from oil, gas and coal.
People who are motivated are never satisfied with the amount of effort they put in. They always crave for more. They are always out there, searching for more and more activities to indulge in. One such example of this kind of active nature is Shweta Dsouza- Professional Fitness and Lifestyle Trainer.
