Nuclear Power Exploitation to Generate Electricity

Introduction The world is facing growing energy demands that traditional electricity generation methods have been unable to satisfy. Nuclear energy has emerged as a feasible option for providing power for the world. Nuclear power stations have experienced great advancements since they were first implemented five decades ago.Advertising We will write a custom research paper sample on Nuclear Power Exploitation to Generate Electricity specifically for you for only $16.05 $11/page Learn More These stations are built with a strong emphasis on safety and cost. They are expected to produce adequate electricity to meet consumer demands and at prices that are competitive compared to other sources of electricity. This paper will discuss how nuclear power has been exploited to generate electricity. How Nuclear Power Works Nuclear power plants generate electricity by harnessing the heat generated from nuclear reactions and using the heat to produce electricity in c onventional ways. The nuclear reaction used by modern power plants is fission which involves splitting radioactive isotopes into two. This process creates a chain reaction as the newly formed nuclei travel at high speeds in opposite directions and collide with neighboring atoms therefore initializing a chain reaction. The nuclear process takes place in a specially constructed nuclear reactor. Sivanagaraju (2010) reveals that the reactor is made up of a core that has the nuclear fuel, control rods for controlling the fission process and a moderator for slowing the neutrons. During the nuclear reaction process, enormous heat energy is generated at the core. Water is used to provide cooling and it is contained in a primary and secondary loop (Sivanagaraju, 2010). The primary loop is in contact with the core which makes it potentially radioactive. The water in the secondary loop is not in contact with the core hence it is not radioactive. During the cooling process, heat energy is trans ferred to the primary loop water. This primary loop water is pressurized to ensure that it remains in liquid state. Using a heat exchanger, the primary loop water heats the secondary loop water turning its water into steam that turns turbines to generate electricity. Advantages of Nuclear Power Nuclear power has reduced the detrimental environmental impact caused by traditional power generation methods. The use of nuclear power has reduced the reliance on environmentally degrading methods such as coal burning and the use of fossil fuels (McKinney Schoch, 2012).Advertising Looking for research paper on other technology?

This power source has therefore led to a significant reduction in the environmental damages caused by power generation. A signif icant advantage of nuclear energy is that it helps satisfy the growing global electricity demands. Due to population increase and industrial growth in many countries, electricity demands have risen rapidly over the last decade. This has put a strain on the traditional sources of electricity such as hydropower and fossil fuels. Nuclear energy has emerged as a feasible alternative, capable of producing reliable power for the remotely near future (McKinney Schoch, 2012). Unlike other alternative sources such as solar power and wind power which are unreliable, nuclear power is able to provide continuous energy. In addition to this, nuclear power is able to significantly reduce the energy dependence that a country has on others. Presently, fossil fuels are the primary source of energy for most nations. However, fossil fuel reserves are only available in a few countries. Many countries therefore have to import the fuels creating a huge energy dependency on the oil-producing nations. Nucl ear power plants ensure that a nation can generate power. This reduces the demand for the fossil fuels and promotes energy independence by the nation (Sivanagaraju, 2010). Finally, nuclear power plants require comparatively less space to implement. Compared to electricity production methods such as solar power plants, wind farms, and hydroelectricity, the space requirements for nuclear power facilities is small (Sivanagaraju, 2010). This is a significant merit since it means that nuclear facilities can be constructed near load centers such as cities where large spaces of land for the other electricity generation methods might not be available.Advertising We will write a custom research paper sample on Nuclear Power Exploitation to Generate Electricity specifically for you for only $16.05 $11/page Learn More Disadvantages of Nuclear Power Nuclear fuel is a nonrenewable energy source meaning that it will run out after a certain duration of use. Loyn (2011 ) explains that the reserves of uranium, which is the primary fissile fuel for modern reactors, are finite and the reserves are projected to be depleted in about a century. As such, while nuclear power stations can serve as an alternative source of energy for the near future, they cannot be relied upon to provide for the global energy needs indefinitely. Another significant demerit of nuclear power is that it produces toxic waste products. This toxic waste is radioactive in nature and can cause harm to the environment. To make matters worse, the waste produced has a very long half-life which means that they remain harmful for thousands of years (Loyn, 2011). The material must therefore be stored safely using expensive and sophisticated storage devices. Nuclear power plants expose the society to significant dangers in the event of a major disaster in the nuclear power plant. If the power plant is damaged significantly, the harmful radiation at the core can escape into the environment causing great devastation. McKinney and Schoch (2012) reveal that nuclear accidents can result in the deaths of up to a hundred thousand people and the radiation poisoning of tens of thousands more. Nuclear Power and the Environment Nuclear power has a mostly negative relationship with the environment. These facilities present a real danger to the environment in case of a disaster in the power plant. The huge quantities of toxic waste produced by power plants are also a danger to the environment. Accidental spillage of the radioactive waste can contaminate food chains and drinking water therefore degrading the environment (Loyn, 2011). In addition to this, the mining and processing of nuclear fuel are harmful to the environment. Uranium mining is energy intensive and huge tracks of land have to be strip mined to obtain the fuel. However, nuclear power can be positive for the environment. Most of the negative effects would require catastrophic failures to occur in the power plant. H owever, this occurs in rare situations since nuclear power plants are built with safety considerations as a priority (McKinney Schoch, 2012). The nuclear power plant therefore presents little danger to the society while reducing the harmful effects caused by fossil fuels.Advertising Looking for research paper on other technology?

Get your first paper with 15% OFF Learn More Modern Nuclear Plants Many governments are beginning to invest in modern nuclear power plants to meet the energy demands of their countries. The World Nuclear Association (2013) reveals that currently, there are over 60 modern nuclear reactors being constructed. These constructions are taking place in 13 countries distributed in various regions of the world. However, most of the nuclear plants are being built in the Asian region where the rising population and growing economy has created a huge demand for energy. China has the largest number of new reactors under construction with 26 reactors already commissioned by the government to increase the country’s nuclear capacity (World Nuclear Association, 2013). The China Guangdong Nuclear Power Group is responsible for most of the nuclear power plant constructions in China. India has seven new power plants under construction and these new plants are being built based on modern western and Russian designs. The Indian public sector enterprise Nuclear Power Corporation of India is responsible for most of the new nuclear power plant constructions in the country. The Future of Nuclear Power Significant advances are being made in an effort to increase fuel efficiency in nuclear reactors. Templeton (2013) reveals that extensive research has been carried out on molten salt reactors (MSR). The concept of molten salt reactors is to use a liquid fuel as opposed to the traditional solid pellets to power the nuclear reactor. When implemented, the molten salt can play the role of both fuel and coolant. It will circulate with the help of pumps from core to heat exchangers with higher thermal efficiency (Templeton, 2013). In the present, technology is not used for commercial purposes. However, as greater energy production is demanded of individual reactors, this technology will become prevalent. Another expected future development in nuclear power is the use of fusion technology. The fusion process involves having the nucl ei of light elements fuse together to form heavier elements (Loyn, 2011). Using this technology will ensure that the world has an unlimited supply of nuclear fuel since ordinary seawater will be used for nuclear fusion. Conclusion This paper set out to discuss how nuclear power is being exploited to generate electricity. It noted that nuclear fission is the method employed by modern power plants. The paper has noted that nuclear power has advantages such as low pollution, reliability, increased energy security, and lower space requirements. However, nuclear power suffers from being a non-renewable resource and the toxic waste produced can harm the environment. The future of nuclear power entails increased efficiency of fuel use fuels through molten salt reactor utilization and perfecting nuclear fusion technology. References Loyn, C. (2011).

Racism By Thomas Jackson

Racism By Thomas Jackson Introduction Racism can be defined as favor of one culture, race and color by undermining other people’s cultures, races, and color. Historically racial discrimination was perceived to be committed primarily by whites especially towards the black population living in the United States and other European countries.Advertising We will write a custom essay sample on Racism By Thomas Jackson specifically for you for only $16.05 $11/page Learn More The emergence of civil activists like Martin Luther and Malcolm X was because of the increased racial concerns. In order to give an explicit reasoning about racism with respect to the words of Thomas Jackson, it is imperative to understand both the current and the past historical issues concerning racism; this will give a clear and unbiased argument about racism based on my own understanding. My perception of Thomas Jackson racism I personally agree and at the same time disagree with the argument presented by Th omas Jackson about racism. To commence my argument about this issue, I will first point out what I personally believe that Thomas Jackson missed about racism. Thomas concentrates only on the current issues and concerns that seem to discriminate on the white race. In doing so, he forgets the historical injustices that whites have shown especially towards the black community. A large percentage of the black communities living in the United States were taken as slaves for the white people. The reverse has never happened anywhere in the world. The propagation of racism was evidently done by the white community. In the early 1960’s at the rise of civil rights movements, most African-Americans and Hispanics were clearly discriminated by their fellow white citizens in most aspects of social life. There were schools for the whites and hospitals for the whites among other necessary social amenities. Thomas seems to forget these past injustices committed by the white communities. If th e black and other races had not been discriminated, the word ‘racism’ could not have attracted much attention as it is in the modern world. By stating the history of racism and the past injustices committed by the white people, I do not support discrimination against the white community regarding their own cultures and identities. However, there is one factor that is clear when talking about racism, the whites triggered racism and blacks and other races have disseminated racism through their over-sensitivity to any act that seems to support or favor the white community. In this respect, there is discrimination against the white community since they cannot exercise their own private practices without attracting overwhelming attention from the media and the ‘modern civil activists’.Advertising Looking for essay on social sciences? Let's see if we can help you! Get your first paper with 15% OFF Learn More As painfully explained by Thoma s in his argument, this side of the argument is true. It is also true that the white community has to be more cautious in their actions more than other races. This perception can be explained by considering historical events that led to racism, in summary the hunter is more or less becoming the hunted. More so, Thomas emphasizes on the growing number of immigrants flocking the United States especially from developing countries. On the contrary there are minimal number of white immigrants to the United States as compared to the number of blacks and other races. This clearly indicates the decreasing dominance of the white community. Conclusion Based on my analysis, Thomas Jackson is neither right nor wrong; his argument seems to be a reaction to the growing sensitivity from other races. There is more reaction to the actions of the other races rather than a comprehensive argument of racism and its origin. In this perspective, Thomas is wrong in his approach about the whole concept of r acism. He ought to analyze the genesis of racism to account for the current actions. In another perspective, the growing concern for any white actions should not be taken as a sign of racism; I personally detest this perception from other races about the white community in support of Thomas argument.

N.A.F.T.A - Assignment Example Moreover, the policies also focused upon codifying broad assortment of agreements related to textile, agriculture, telecommunications, auto trade, intellectual properties, flexibility of workers and environmental policies (Ford, â€Å"A brief history of NAFTA†). Thesis Statement The discussion would aim to analyze the purpose of NAFTA. It would also attempt to provide an insight into the history of NAFTA along with ascertaining the favorable as well as unfavorable outcomes on the US and world economy. A Brief History of NAFTA NAFTA was established in the year 1994 for the purpose of trimming down the costs related to trading, raising business funds and most significantly promoting financial growth among Mexico, Canada and the US. The agreement i.e. NAFTA which was duly signed by the different leaders of the participating nations was ratified by the Congress of the US in the year 1993. It was observed that the agreement proved to be quite controversial as most of the manufactur ing industries as well as the makers of agricultural commodities belonging to the US faced the threat of losing the business market by competing with the Canadian along with Mexican business firms due to their lower cost arrangements (Ford, â€Å"A brief history of NAFTA†). ... Additionally, the fundamental purpose of NAFTA is to ensure and maintain a smooth flow of goods as well as services by making substantial investments. Moreover, the agreement aimed to provide each of the participating countries the prominence in terms of substantial favored trade in the business market. With regard to the purpose of NAFTA, it has been observed that the agreement encompassed certain important areas which comprised the abolition of non-tariff associated trade barriers, augmentation of financial investments and reduction of environmental issues. Moreover, the agreement also entailed segments such as trimming down the tariffs and developing the trade rules such as dispute settlement methods. However, on the basis of the above discussion, it can be stated that the chief aim of NAFTA is to generate a situation of free trade amid the nations of Mexico, Canada and the US by the exclusion of tariffs along with other trade barriers. The agreement i.e. NAFTA can be considered a s a major initiative owing to the different imperative purposes of the trade policies (Rosson, Benson, Moulton and Sanders, â€Å"The North American Free trade Agreement and U.S. Agriculture†). Effects of NAFTA on US World Economy NAFTA was found to pose significant effects upon the world economy of the US. Due to the implementation of NAFTA, the trade relations between the nations i.e. Mexico, Canada and the US broadened substantially. It becomes necessary to be stated in this context that the supporters of NAFTA declared the agreement to be a successful one for supporting the producers of the US by generating a free trade amid the participating nations. Moreover, the agreement benefited the

Nutrition, Physical Activity and Weight - Essay Example From this study it is clear that  evidence based messages to promote healthy nutrition in adolescents should target food groups, snacks, meals, fast food and beverages. Teenagers should ensure that their diet contains a variety of foods such as grains, meat, poultry, dairy products, fruits and vegetables, and nuts to accommodate their growth requirements of minerals, vitamins, proteins, carbohydrates and fats. Daily 5 servings of fruits and vegetables are recommended.This paper highlights that energy dense-nutrient poor foods such as fried potato chips, biscuits and cakes lead to a lower intake of fruits and vegetables and are more likely to be associated with consumption of other energy dense-nutrient poor foods like colas. Energy drinks and soft drinks should be consumed in limited quantity because of their high caffeine and sugar content. Current research suggests that reducing consumption of sugar sweetened and carbonated drinks can help in obesity prevention. Instead, water in take should be increased. They should be taught to read the labels before consuming packaged and processed foods regarding calories, fat and sodium content of the product and choose accordingly and wisely. Also, difference in home cooked and processed food can be explained and reasons for ‘eating out’ analysed.  Adolescents should be explained about the benefits of staying physically active and how it can be achieved. Teenagers should be encouraged to take part in sports and other physical activities at school.

Donald McKay :: essays research papers fc

  Ã‚  Ã‚  Ã‚  Ã‚  During the 1840’s and 1850’s America experienced its golden age in shipping and sailing.1 At the front of this era was Donald McKay whose innovative ship designs lead to the numerous sea speed records, some of which stand today. For most of the early 19th century American ship building consisted of merchant and cargo ships. It took a long time for these ships to sail across seas. With the increased speed came decreased time to wait for pay. Another need for increased speed was the California gold rush of 1849. People wanted to make the trip as quickly as possible in order to stake their claims. Donald McKay’s clipper ships enabled people to do that.   Ã‚  Ã‚  Ã‚  Ã‚  This paper investigates why Donald McKay is the father of American clipper ships. He was born in Shelburne, Nova Scotia, September 4, 1810.2 When Donald was sixteen years old he had the desire to learn the trade of ship building, so he went to New York. In 1826 New York was the worlds best shipbuilder and shipbuilding was America’s leading industry. McKay decided that in order to learn the trade he must obtain an apprenticeship. So he became an apprentice to Isaac Web who has appropriately been called the â€Å"Father of Shipbuilders†. This is because more successful master shipbuilders came out of Web’s shipyard than from any other place in America.3 At the conclusion of his apprenticeship he went on to work for Brown & Bell. In 1832 packet building was the best and most readily available work in New York. The majority of these ships were built at Isaac Web’s, Brown & Bell’s, and Smith & Dimon’s. At this time McKay was wh at would be called a free lance ship wright. McKay then married Albenia Martha Boole the eldest daughter of John Boole.4 At this time McKay then went to Newburyport and formed a partnership with William Currier.   Ã‚  Ã‚  Ã‚  Ã‚  They formed the firm Currier & McKay and built the Courier. This was McKay’s first real production as designer and builder of a ship. The Courier was built for the coffee trade between New York and Rio de Janeiro and was sold to Andrew Foster & Son.5 Their firm soon dissolved and McKay then become connected with William Pickett and formed the firm of McKay & Pickett. Under this name they built the New York packet ship St. George. This was the first of the Red Cross Line.

Hawa Mahal Essay

Hawa Mahal stands upright as the entrance to the City Palace, Jaipur. An important landmark in the city, Hawa Mahal is an epitome of the Rajputana architecture. The splendid five-storey â€Å"Palace of the Winds† is a blend of beauty and splendor much close to Rajasthan’s culture. Maharaja Sawai Pratap Singh built Hawa Mahal in 1779. The pyramid shape of this ancient monument is a tourist attraction having 953 small windows. 2. Taj Mahal Taj Mahal, the pinnacle of Mughal architecture, was built by the Mughal emperor Shah Jahan (1628-1658), grandson of Akbar the great, in the memory of his queen Arjumand Bano Begum, entitled ‘Mumtaz Mahal’. Mumtaz Mahal was a niece of empress Nur Jahan and granddaughter of Mirza Ghias Beg I’timad-ud-Daula, wazir of emperor Jehangir. She was born in 1593 and died in 1631, during the birth of her fourteenth child at Burhanpur. Her mortal remains were temporarily buried in the Zainabad garden. Six months later, her body was transferred to Agra to be finally enshrined in the crypt of the main tomb of the Taj Mahal. The Taj Mahal is the mausoleum of both Mumtaz Mahal and Shah Jahan. Victoria Memorial Victoria Memorial, one of India’s most beautiful monuments, represent a unique combination of classical European architecture and Mughal motifs. The domed and white marble museum sprawls over 64 acres and is set in a landscaped garden at the southern side of the Kolkata’s maidan (ground) near Jawaharlal Nehru Road. Charminar The charminar Hyderabad’s best known landmark was built 1591 by Sultan Mohammed Quli Qutub Shah to appease the force of evil savaging his new city with epidemic and plague. Standing in the heart of the old walled city and surround by lively bazaars, the charminar (‘four tower’) is a 56m high triumphal arch. The arch is notable for its elegant balconies, stucco decorations and the small mosque, Hyderabad’s oldest, on the 2nd floor. An image of the grace every packet of charminar cigarettes, one of India’s most popular brand. 6. Sanchi Stupa Sanchi is situated in the state of Madhya Pradesh in India. It lies at a distance of approximately 52 km from the capital city of Bhopal and 10 km from Vidisha. The major attractions of Sanchi include a number of Buddhist stupas, monasteries, temples and pillars. All these structures date back to somewhere between 3rd century BC and 12th century AD. The Mauryan emperor Ashoka founded all the stupas at Sanchi in the honor of Lord Buddha. They have the distinction of being included by unesco in the list of world heritage Qutab Minar Qutub-ud-din Aibak laid the foundation for Qutub Minar in 1199 AD and his successor and son-in-law Shamsu’d-Din- Iitutmish completed the structure by adding three more stories. Standing at 72.5 meters, it is the highest stone tower in India. Its base diameter is 14.3 meters and its top diameter is 2.7 meters. It has 379 steps leading to its top story. The lower three stories are made using red sand stone and the top two with marble and sand stone Gateway The majestic Gateway of India is a glorious historical memorial built during British rule. This magnificent monument has been built in Indo-Sarcenic style to commemorate the visit of King George V and Queen Mary to Bombay. Gateway of India is one of the finest example of colonial architectural heritage in India. This grand structure stands at the Apollo Bunder, a popular meeting place in Mumbai. The gateway of India was designed by the British architect George Wittet and was opened for general public in the year 1924
