Nuclear fission is the process of splitting atoms larger than iron, such as Uranium or Plutonium into two smaller atoms with the release of huge amount of energy and neutrons. Nuclear fission is discovered first. …

Controlled nuclear fission is used to generate electricity and uncontrolled nuclear fission is used to make nuclear weapons, such as atomic bombs and hydrogen bombs. Nuclear fission also produces a large amount of nuclear wastes. “In nuclear weapons, fission and fusion of certain slightly radioactive materials release energy in a huge explosion” (Medalia, 2004, p. 1).
“The element uranium is the main fuel used to undergo nuclear fission to produce energy since it has many favorable properties. Uranium nuclei can be easily split by shooting neutrons at them. Also, once a uranium nucleus is split, multiple neutrons are released which are used to split other uranium nuclei. This phenomenon is known as a chain reaction.
Nuclear fusion is the process of joining two atoms smaller than iron such as hydrogen or helium to produce heavier atoms and that large amount of energy is produced in this reaction, which is much more than the energy produced by nuclear fission. Nuclear fusion is the main source of energy in the universe because all the stars including the sun produce energy by nuclear fusion. Other than nuclear fission, man has not yet discovered a method to control nuclear fusion, and nuclear fusion is not used to generate electricity. Scientists are working hard to discover a method to control nuclear fusion so that it can be used to generate electricity. Nuclear fusion is only used in hydrogen bomb which is the deadliest weapon humanity has ever seen. The temperature required to start a nuclear fusion is so large that it is provided by the explosion of an atom bomb.
Benefits of Nuclear Energy: The largest advantage of nuclear power is that it does not emit any harmful gases to the atmosphere like carbon dioxide, sulphur dioxide, or nitrogen dioxide, that is, no green house gasses like carbon dioxide is emitted to the atmosphere, and so using nuclear fuel can reduce global warming. As nitrogen dioxide and sulphur dioxide are not emitted, acid rains can also be reduced. The only emission from nuclear reactors is water vapor. Hence nuclear energy is known as clean energy. “It is difficult to explain to a non-specialist (though it is actually true) that the nuclear reactor of a nuclear power station is nothing like an atomic bomb, that the power station burning coal or oil offers much greater danger and harm to the environment as well as a biological threat to people than does a nuclear station or breeder reactor of the same capacity rating” (Sakharov, 1978, p. 12). “Although the initial cost of building nuclear plants is high, the running costs are relatively low. One reason the costs are low is that nuclear plants need only a small amount of uranium to produce a lot of energy. In fact, if the cost of uranium is doubled, costs would only be increased by 7%. 1 truck of uranium produces as much energy as 1000 trucks of coal!” (Advantages of Nuclear Power, 2012). Efficiency: Another major advantage of nucl

By the law of conservation of energy, one type of energy can be converted to the other (TutorVista.com). Every type of energy can be converted to the other. Thermal, solar, wind, hydrodynamic, geothermal and other types of renewable energy sources can be utilized to generate electrical power.
The cost of nuclear electricity has come down in the recent past and the impediments to the expansion of nuclear energy at this point are mainly restricted to problems that arise out of the ignorance of people regarding the processes that are associated with nuclear energy and the accidents that happen as a result of instances of human negligence.
These events have unfortunately created misconceptions about nuclear power, which highlight more on perceived disadvantages than its benefits. This paper is a critical examination of nuclear energy focusing on its advantages and disadvantages in relation to other sources of energy.
The search of alternate energy source is revolving around solar energy and nuclear energy. Even though solar energy is renewable in nature, feasible technologies to convert it into useful energy forms are still not developed properly. On the other hand, the technology for the exploitation of nuclear energy is well developed.
All scientists agree today that this increased concentration of greenhouse gases is responsible for climatic change, change that is perhaps natural, but is certainly accelerated by human activity. These discharges are caused mainly by transport vehicles. However, the use of fossil fuels in the generation of electricity is also contributing to the worsening situation.
According to the report scientists discovered that splitting of certain heavy atoms could result in production of enormous amount of energy. This fundamental process is the heartbeat of all the nuclear processes taking place in today’s world. Over the history, this form of energy production has served for various purposes and applications.
These countries are France, Japan, and the United States. This is despite the fact that there are 439 nuclear reactors for power generation scattered across 31 countries. Statistics have shown that this
When the atoms are merged or split in a set process of chemical reactions, nuclear energy is created (Kate 2002). When the nucleuses of an atom are split it is called fission but when they are merged it is called
Fission is basically separating an atom into two atoms and the energy produced during the separation is transformed in massive energy. The current issue of global warming has led to the popularity of nuclear energy since its mitigation is
