CO2 and methane from the primary contributors to the greenhouse effect, while carbon monoxide is very toxic. The only gaseous exhaust is water vapor produced by nuclear reactors. Later expiration dates than fossil fuels, the reserves of uranium in the earth can hardly be called 'endless', thorium, which is much more abundant, could supply electricity to the world for at least half a Millennium. Fossil fuel reserves are, even by the most confident forecasts, hopes that have been exhausted at the time. The main drawback to using thorium as nuclear fuel is that naturally found form (isotope) of thorium is not fissile, unlike natural uranium format found. The isotope natural thorium must be transformed into a fissile material before it can be used as nuclear fuel. Although uranium is currently the nuclear fuel of choice, many countries, the one that stands out is India, they have recognized massive research on the suitability of the thorium as a replacement for uranium, and we could soon have thorium fuel our nuclear reactors instead of uranium. Nuclear Fusion research in progress could well announce its arrival as a source of universal energy. Fusion of two nuclei of hydrogen to form a molecule of helium, which is most widely used. The fusion reaction produces exponentially more energy than fission. The amount of energy manufactured by fusion

Nuclear energy is the world's largest source of emission-free energy. Nuclear power plants produce no controlled air pollutants, such as sulfur and particulates, or greenhouse gases. "Renewables" like solar, wind and biomass can help. But only nuclear power offers clean, environmentally friendly energy on a massive scale. The use of nuclear energy in place of other energy sources helps to keep the air clean, preserve the Earth's climate, avoid ground-level ozone formation and prevent acid rain. “Currently, there are 103 commercial nuclear power plants producing electricity in the United States, located at 64 sites in 31 states. They are, on average, 24 years old, and
Nuclear energy is defined as energy released by reactions within atomic nuclei, as in nuclear fission or fusion (“Dictionary”). Nuclear fission is defined as a nuclear reaction in which a massive nucleus splits into smaller nuclei with the simultaneous release of energy. The definition of nuclear fission is as reaction in which two nuclei combine to form a nucleus with the release of energy (“Dictionary”). The process of nuclear fission and fusion happen inside of a nuclear reactor that is located in a nuclear power plant. Also needing to be defined, a nuclear reactor is a device in which nuclear fission initiates a controlled chain reaction, producing heat energy typically used for power generation, and neutrons and fission products (“Dictionary”). It is also important to know that there are a few different kinds of nuclear reactors. The different kind of reactors include: pressurized water reactors, boiling water reactors, gas-cooled reactors, and light water graphite reactors (Blau 117). Finally, a nuclear power plant is a facility for the production of electricity using
Debates about the use of nuclear power plants in New York City have received much attention in the last few years. Many scientists believe that the use of Nuclear Power would be beneficial for New York City, since an abundant amount of electricity is necessary to fuel the Big Apple; however, one primary argument espoused by opponents is that the use of nuclear power will bring about negative effects like radiation exposure, debt and may allow the power plant to become a potential target for terrorist attacks. This paper describes selected constitutional issues related to the use of nuclear power plants with a focus on the risks it poses and concludes with implications for alternative sources of energy.
Summary: In this paper I will discuss the overall of nuclear energy to rectify some misconception. I will give the advantages and disadvantages for using nuclear energy and let the readers understand the basic idea of it.
The use of fossil fuels as a primary source of power is poisoning our world, and nuclear power is just the way to stop this. Nuclear power is using the process of nuclear fission to create electricity. Nuclear fission is the splitting of a uranium atom to release massive amounts of energy. When this process takes place in a nuclear reactor, the energy is used to superheat water which is pumped through pipes also submerged in water which then boils. The pressurized water vapor is used to turn turbines that produce electricity. Nuclear power is one of the cleanest, safest, most reliable and economically beneficial sources of power, and it needs to be considered as a substitute for fossil fuels. Nuclear power unfortunately has been given a bad name, but is actually an important resource that should be utilized by the U.S. and the rest of the world.
Nuclear power produces huge amount of energy through nuclear fission. 1 ton of uranium fuel, which is used as a fuel in generating electricity, equals to 50,000 tons of fossil fuels for generating the same amount of electricity. Since a small amount of nuclear fuel can produce a large amount of energy, it is powerful and efficient.
It is estimated that at today’s rate of consumption, the earth has about fifty years left of fossil fuels. In contrast, due to the very small amount of uranium needed to create a huge amount of energy, the supply of nuclear energy is almost infinite [Jiskha].
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.
Nuclear power is generated from the energy that is released from a heavy nucleus into a lighter, more stable nuclei. The heat produced is used to boil water which drives a steam turbine to generate electricity. This chain reaction process is also called fission. A key element to fuel nuclear plant is uranium. Uranium is considered to be a nonrenewable energy source, even though it is a common metal found in rocks worldwide. U-235 is most commonly used in plants because its atoms are easily split apart. To extract U-235 uranium ore is mined; for the United States, this element is found in the
The world's natural resources are being consumed at an alarming rate. As these resources diminish, people will be seeking alternative sources by which to generate electricity for heat and light. The only practical short-term solution for the energy/pollution crisis should be nuclear power because it is available, cleaner and safer.
Global demand and consumption of energy is at an all time high; the world needs a safe, efficient, clean, and high producing source of energy production. The solution is something we already use for energy production, Nuclear power. From the beginning of nuclear energy there has been concerns over the safety of the power plants and its impact on the environment. With climate change and more accurate information on nuclear power the tide is shifting in its favor. This paper will explore the positives of nuclear power, political change on nuclear power, safety of the energy source and new technologies associated with the nuclear power process. Most importantly are the risks associated with nuclear power worth it? Research suggests that nuclear power is safer now more than ever and has less of an impact on the environment than coal or oil. Public support and misconceptions over the years have been up and down due to political agendas and those who are misinformed about nuclear power. Individuals who are involved in the energy field are in favor of nuclear power and building more plants with newer technology.
Nuclear energy is an alternative source of energy that holds great amounts of energy and is one of the future sources of energy for this world. “Nuclear energy is energy in the nucleus (core) of an atom. There is enormous energy in the bonds that hold the nucleus together. Energy is released when those bonds are broken” (Uranium). Unlike a chemical reaction with fossil fuels, nuclear reactions create an even greater amount of energy than fossil fuels. “Nuclear energy can be used to make electricity, but first it must be released it can be released from atoms in two ways: nuclear fusion and nuclear fission” (Uranium). Nuclear energy already provides 1/5 of all the energy in the U.S.,
