One of the advantages of using nuclear energy in Malaysia is that it can generate low prices electricity compared to the other source (Kok, 2009). Rates for nuclear energy are presumably cheaper than power generated from other sources such as coal and gas. This is because the source of nuclear energy which is Uranium is available in large amount (Pan, 2008). When a certain material or source is available in large amount the price is cheap. The cost of Uranium is cheaper than any other source; the cost has dropped over the last 26 years compared to other energy (Pan, 2008). The usage of Uranium is far lower than fuel, meaning an energy produced from dozen tons of fuel is nearly the same as energy produced from tons of Uranium.
The second advantages of using nuclear energy are the nuclear energy waste product is clean. According to (Abhijit, 2010), the creation of nuclear energy does not contribute to environmental problem. A research by (Abhijit, 2010) found that nuclear energy produce less polluting than the coal and petroleum because can generate electricity with n...
Nuclear power, or nuclear energy, is the use of exothermic nuclear processes,[1] to generate useful heat and electricity. The term includes nuclear fission, nuclear decay and nuclear fusion. Presently the nuclear fission of elements in the actinide series of the periodic table produce the vast majority of nuclear energy in the direct service of humankind, with nuclear decay processes, primarily in the form of geothermal energy, and radioisotope thermoelectric generators, in niche uses making up the rest. Nuclear (fission) power stations, excluding the contribution from naval nuclear fission reactors, provided about 5.7% of the world's energy and 13% of the world's electricity in 2012.[2] In 2013, the IAEA report that there are 437 operational nuclear power reactors,[3] in 31 countries,[4] although not every reactor is producing electricity.[5] In addition, there are approximately 140 naval vessels using nuclear propulsion in operation, powered by some 180 reactors.[6][7][8] As of 2013, attaining a net energy gain from sustained nuclear fusion reactions, excluding natural fusion power...
Not only is nuclear power friendly to the environment, but it is almost always available, and many countries are starting to use it more. Renewable energy sources like solar and wind en...
Depending on progress of technology of the countries’ energy consumption is increasing day by day. Countries have started to use different kinds of energy sources like hydropower, solar, wind, waves and nuclear energy except fuel foils to close their energy gaps. Especially in the developed countries all of the hydroelectric production capacity has almost used yet the alternative energy sources such as solar, wind, geothermal and biomass is limited. Using fossil fuels or coal cause many problems such as environment and air pollution. Because of these limitations governments have directed to use nuclear energy sources. The main advantages of the nuclear energy are the cheapest price, low environmental pollution and long lasting source of the reserves. This paper discussed the advantages and the disadvantages of the nuclear energy which is used as an indispensable energy source in France, Germany, Italy, UK, USA, and some Scandinavian countries, Russia and many other countries. In this essay, it is claimed that in this c...
Nuclear power is the generation of electricity from an atomic reaction. (World Statistics: Nuclear Energy Around the World n.d.) Though it produces zero carbon emissions there has been a decline in support for nuclear power and increased its support for alternative energies in the pursuit for a fossil free energy sector. Factors that have resulted in the reduction of support for nuclear energy include nuclear accidents and waste and the positives of renewable energy which include clean energy, sustainable and reduced health and environmental risks.
There are six authors that will be mentioned in this paper. Three of the authors are for nuclear energy and three of them are against nuclear energy. The first three authors that will be introduced are for nuclear energy. Naim H. Afgan is a professor at the Superior Technical Institute in Lisbon, Portugal and the Chair Holder for the Energy Sustainable Management. He is also a member of the VINCA Institute of Nuclear Science that is in Belgrade that he joined in 1957. He published over 200 papers, including his article on nuclear energy that will be used in this paper. The next au...
Today our society is using more energy than ever. With the increase in demand for energy, problems are presented that have to be addressed. One of the biggest and most prevalent problems is the need for clean, renewable, sustainable energy. On the forefront of these problems comes the following solutions: nuclear energy, hydro-electric energy, and photovoltaic energy. With the need of energy in today’s current world, exploring different ways of producing power are necessary. The differences and similarities of nuclear energy and alternative energy are important to look over and examine in depth, so that it is plain to see the positive and negative effects of energy production.
Nuclear power has proven before that it can result in tragedy, both seen in the accident in Chernobyl and Fukushima. However, in places such as France and even the University of Maryland, we can see the many advantages that nuclear energy can bring forth, and for different purposes. In both research and energy production, nuclear energy has proven that it can not only improve our health and the economy, but also emit less harmful gases on the environment than fossil fuels. Looking to the future, nuclear energy can easily ascend as a dominant source of electricity – if properly managed. Other sources of energy will slowly deplete and continue to damage the environment and atmosphere. Nuclear power provides a solution to so many of the current energy crisis problems, so it is only a matter of
Nuclear power has grown to be a big percentage of the world’s energy. As of January 18, 2013 in 31 countries 437 nuclear power plant units with an installed electric net capacity of about 372 GW are in operation and 68 plants with an installed capacity of 65 GW are in 15 countries under construction. As of end 2011 the total electricity production since 1951 amounts to 69,760 billion kWh. The cumulative operating experience amounted to 15, 15,080 years by end of 2012. (European Nuclear Society) The change that nuclear power has brought to the world has led to benefits in today’s energy’s usage.
Nuclear energy is energy inside the nucleus of an atom and it is the energy that is holding the proton and neutrons together. Nuclear energy can be converted by a power plant into electrical energy and the power plant is called nuclear power plant. There is two ways to obtain the energy. There is nuclear fusion and nuclear fission. Nuclear fusion is where atoms are combined together to form a larger atom and nuclear fission is where the atoms are split to produce the energy. In fact, nuclear power plant only can use nuclear fission to produce energy.
Around 1894, scientists discovered that by bombarding a radioactive substance with neutrons, a highly powerful energy could be produced. This is ionizing radiation, which is strong enough to rip the electrons from the nucleus of an atom, hence the name “nuclear energy.” over a century later, nuclear substances are harnessed in order to provide energy. However, nuclear energy is not only discussed amongst scientists, but anyone fearing the safety and future of the environments surrounding the area where a nuclear power plant is implemented.
Nuclear Power, The generation of power using highly radiated uranium pellets in fuel rods used to heat up water and run turbines. This is why Congressman Bill Nelson should not support the building of a new nuclear power plant in the state of Florida.
“Every dollar spent on nuclear energy is one less dollar spent on clean renewable energy and one more dollar spent on making the world a comparatively dirtier and a more dangerous place, because nuclear power and nuclear weapons go hand in hand” (Jacobson). Most countries today are becoming more and more dependent on nuclear power as a source of energy because of its high energy output and the availability of uranium used for fuelling nuclear reactors that generate power to provide electricity in households. Although using nuclear power as a source of energy has benefits like this, the danger posed by using nuclear power is too ominous.
Nuclear energy has been identified as an effective source of electrical power that is being capitalized upon around the world. While nuclear power offers benefits, such as sustainable energy, the risks associated with it including nuclear accidents, proliferation, and terrorism make it a gamble. The probability of such events occurring is low, but the impact they could cause is immense. However, the irreversible effects of climate change override the concerns with nuclear power which can be alleviated by heightened security and international efforts.
The use of nuclear energy has increased in the United States since 1973. Nuclear energy's share of U.S. electricity generation has grown from 4 percent in 1973 to 19 percent in 1998. This is excellent news for the environment. Nuclear energy and hydropower are the cleanest large-scale means of electricity production. Since nuclear power plants do not burn fuel, they emit no combustion byproducts—like carbon dioxide—into the atmosphere (www.nei.org). Nuclear power can come from the fission of Uranium, plutonium or thorium or the fusion of hydrogen into helium. Today uranium (U-235 and U-238) is most commonly used in the production of nuclear energy. The expa...
The greatest disadvantages of nuclear energy are the risks posed to mankind and the environment by radioactive materials. ‘On average a nuclear plant annually generates 20 metric tons of used nuclear fuel cla...
