Nuclear energy has been a controversial source of alternative energy since it has been made practical in the 1950s. The goal of nuclear energy was to find a sustainable resource that would be able to replace the use of fossil fuels. Due to the exploitation and finite supply of resources such as oil and coal, an alternative to fossil fuels was needed quickly in order to provide sustainability for the future of the world. A question arises, however, when nuclear energy is considered as a source of energy: Is nuclear energy a reasonable alternative to fossil fuels? Background Nuclear power is generated by using electricity created during a controlled fission or fusion reaction (“Nuclear Energy.” Global Issues in Context Online Collection). Nuclear fission is a process that releases energy when a nucleus in one atom is separated into two nuclei. Nuclear fusion occurs when the nuclei of two hydrogen atoms are fused together producing a larger nuclei along with energy (“Nuclear Energy.” Opposing Viewpoints Online Collection). In the 1950s, the use of nuclear power became a realistic idea for countries with nuclear capabilities and nuclear power programs (“Nuclear Energy.” Global Issues in Context Online Collection). The international nuclear program grew rapidly and by 1999 there were 436 nuclear power plants in 32 different counties. The United States, Japan, Canada, Russia, India and France remain the largest users of nuclear energy since the 1990s; however, the dependency on nuclear power varies greatly around the world because of differences in the individual nuclear power programs availability of needed resources (“Nuclear Energy.” Opposing Viewpoints Online Collection).

Terrorist attacks on nuclear power plants or terrorist attacks involving nuclear waste could have incredibly detrimental effects on the human population and must be considered when assessing the dangers of nuclear energy production (Peterson and Rohrer). The world is facing an energy crisis and many are unaware of this growing problem. Sustainability is avoiding depletion of our natural resources in order to provide for future generations, and the only way to ensure that resources are available into the future is to find alternative sources to meet the world’s energy needs. Nuclear energy is just one source of alternative energy being implemented today in an effort to support the needs of the population and mitigate global climate change. Nuclear energy holds the necessary benefits in order to continue being used globally as an alternative solution.
Nuclear energy must be a consideration for the future with the rapidly depleting supply of fossil fuels. This type of energy can be created through nuclear fission and nuclear fusion. Nuclear fission is the splitting of a heavy atom into two or more parts, releasing huge amounts of energy. The release of energy can be controlled and captured for generating electricity. Nuclear fusion involves bombarding hydrogen atoms together to form helium. In the long run, nuclear fusion has greater potential than fission.
There are many sources of energy today, and the best source of it is constantly being sought after, one source stands out above the rest. Nuclear energy is simple in theory, yet it may be one of the most controversial sources of power. Nuclear energy works using reactors built to split the atoms (nuclear fission) of the fuel to produce heat. This heat evaporates the cooling agent (usually water) into steam which turns turbines to create electricity. Nuclear energy should be allowed, because it produces an abundance of electricity, as well as being a clean source of energy with no harmful emissions. Nuclear energy is the future of clean, environmentally friendly energy.
The continuous spread of nuclear technology and nuclear weapons is a threat for national security and the safety of the entire planet. The inextricable link between nuclear energy and nuclear power is arguably the greatest danger of nuclear power. The same low-enriched uranium that is processed in a nuclear power plant is the same uranium used to make nuclear weapons. Nuclear power plants are the contributors to these mass destruction weapon capable of wiping out the human race. An article published by the World Nuclear Stockpile Report says, “ Nine countries in the world posses a total of 15,375 nuclear weapons.
Central Idea: Nuclear energy only contributes a small amount to the world’s electricity yet it has hazards and dangers that far out-way its benefits. There are many other alternative power producing sources that can produce energy more efficiently and more safely than nuclear power plants can.
Nuclear power is a very strong yet dangerous element, it has made a huge impact on our economy. Most technology now is powered by Nuclear energy. In many cases the main focus on Nuclear Energy is its advantages (pros), yet no one really pays attention to the dis advantages in Nuclear Energy (cons). But to produce electricity from Nuclear Power, the Nuclear Plant makes a chain reaction, this reaction is then created by a very heavy nuclei that are capable of nuclear fission.
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...
Nuclear energy is energy that is released by reactions within the atomic nuclei, through nuclear fission or fusion. Nuclear energy is also called atomic energy (dictionary.com, 2013). Nuclear energy is produced in nuclear power plants. Nuclear power plants create electricity by heating water to create steam. The steam runs a generator that creates the electricity. Many types of fuels can be used to create heat and generate steam. Nuclear power plants create the heat by splitting atoms. Nuclear power plants use a radioactive element found in rocks called enriched uranium. Enriched uranium is used because when it breaks down in nature it heats Earth’s crust. In nuclear power plants enriched uranium heats water to create steam. Power plants create energy by splitting the nuclei inside each granule of uranium. This process is called nuclear fission (How does energy work, 2013).
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...
Our world today is growing every day every year and there will be a time where more and more energy will be needed to sustain human life. The demand for electricity and its value is increasing rapidly and will only continue to do so. The world will need greatly increased energy supply in the next 20 years, especially clean generated electricity [WNA, 2014]. Fourteen percent of the world’s electricity comes from nuclear energy to use. The use and demand for electricity will increase in 2030 by eighty one percent. Therefore, nuclear power plants need to rise to fulfill the demands and needs for the growth of the population. Since the demand for electricity is increasing and with many resources to get electricity from, the use of nuclear energy without constant support will probably decline to around 9 percent or less by 2035. At least two factors will make this quite difficult for nuclear energy to gain a bigger m...
To begin, nuclear power is produced by nuclear fission, which is the splitting of an atom to start a chain reaction (“11 Facts”). This chain reaction produces massive amounts of heat. Nuclear reactors take advantage of this heat by pumping water into the reactor, which in turn produces steam. The steam then becomes pressurized through a pipeline and exits into a turbine (“How do Nuclear”). The pressurized steam causes the turbine blades to spin, producing power which is linked to a generator for use in the main power lines. When the steam passes the turbine blades, it goes past cooled pipes and condensates (“How do Nuclear”). After the condensation process is finished and the steam reverts back to water, it is pumped into the reactor again, thus completing the process of producing nuclear-based power.
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...
Many questions are asked regarding nuclear energy. How is it used? What can it be used for? What are the different ways it can be used? One of the most important questions asked is the safety. Is nuclear energy safe? The simple answer is yes. Generating electricity from nuclear power and radioactive materials is efficient, reliable and most importantly secure.
Nuclear power, the use of exothermic nuclear processes to produce an enormous amount of electricity and heat for domestic, medical, military and industrial purposes i.e. “By the end of 2012 2346.3 kilowatt hours (KWh) of electricity was generated by nuclear reactors around the world” (International atomic energy agency Vienna, 2013, p.13). However, with that been said it is evident that the process of generating electricity from a nuclear reactor has numerous health and environmental safety issues.
It seems as though nuclear power has always been under question regarding its safety. Its effectiveness cannot be denied, but people are highly skeptical of having a nuclear power plant anywhere near their home. Countless studies have been done to help determine how safe they really are, and most articles tend to say they are quite safe. While searching for an article talking about nuclear power, I came across one titled How safe is nuclear power? A statistical study suggests less than expected, by Thomas Rose and Trevor Sweeting. This title intrigued me because, in my personal experience at least, I have seen far less academic articles going against nuclear power. As someone who likes to see things as objectively as possible, I enjoy hearing
Media coverage of such cases have made the public less comfortable with the idea of moving further towards nuclear power and they only opt for reducing human activities to reduce global warming. It is true that there have been some notable disasters involving nuclear power, but compared to other power systems, nuclear power has an impressive track record. First, it is less harmful and second, it will be able to cater for the growing world population. Nuclear power produces clean energy and it delivers it at a cost that is competitive in the energy market (Patterson). According to the US Energy Information Administration, there are currently 65 such plants in the Unite States (National Research Council). They produce 19 percent of the total US energy generation.
