The Valid and Invalid of the Nuclear Energy Have you ever imagined living without the energy? According to the science dictionary, energy is defined as the capacity of a physical system to perform work. Nowadays people use lots of energy in their life. They use light energy when they turn on or turn off the light. Also, they obtained wind energy and solar energy as a ‘green’ energy from the environment. The application of energy wrought major changes in our society. People invented solar batteries, solar chargers, and even build a solar house. If energy always influenced society with good effects, the society will grow positively and make economic development. However, the energy does not always give positive solutions to the society.

When the nuclear energy work positively, people obtained lots of merits from them, yet, if not, people and all the environment get in to extreme danger. In the simplest term, nuclear energy is energy from interaction with the protons and neutrons of an atom, and the energy obtained during nuclear reaction. It is relating to the strong force, and this energy is released by nuclear reaction called fission and fusion. Fission is the action of dividing of splitting something into two more parts. Fusion is the process or result of joining two or more things together to form a single entity. Nuclear reaction like fusion and fission release very high amounts of energy. How is energy obtained from this source?
There are lots of benefits to using nuclear energy. These are the advantages of nuclear energy: Produces large amount of energy, green energy, no air pollution, and fuel independence. Nuclear energy has ability to produces a million times more energy as compared to other energy such as hydro or wind energy. Moreover, it can

There is energy uses that involved both advantages and disadvantages of nuclear energy. Radiation is “the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause i`onization. Moreover, it is one of the biggest drawback of nuclear energy. People used radiation when they taking picture of inside body by using x-ray, and remove cancer cell. Also, they used radiation when they create plant mutant. Radiation is necessary for the people since they used a lot in their life. However, radiation is more come in contact with the environment and resulting in severe damage to the ecosystem and loss of life rather than provide comfortable life. Too much radiation cause human die and give side effect since it has large amount of nuclear energy. Also, lots of nuclear waste will be left after using radiation, and those nuclear waste cannot be eliminated. Transporting nuclear waste is also one of the biggest issue. Nuclear waste is produced by the nuclear fuel cycle at every stage, from uranium mining and enrichment, to reactor and nuclear spent fuel- reprocessing operation. The vast majority of nuclear waste produced will remain dangerous for hundreds of thousands of years, and will leave a toxic legacy for many
Power plants burn fuel to produce heat to generate energy; however, nuclear power plants use the heat given off fission to turn water into steam. Nuclear energy is without a doubt a great way to power our homes because, Nuclear power plants are safer than other energy alternatives. Nuclear plants are safer than other energy alternatives. Coal is responsible for five times more deaths than nuclear power plants, coal also causes over one thousands more serious causes of illness than nuclear. Nuclear plants produce steam while coal plants, heat water by burning coal that produces greenhouse emissions.
In “Nuclear Power is Not the Answer,” Helen Caldicott argues that pursuing nuclear energy would be a detriment to the United States. According to Caldicott, nuclear power, contrary to what the industry claims, is not clean and green, but rather a pollutant and a strong contributor to the destruction of the ozone layer. Because of the availability of uranium ore steadily decreasing, the process is requiring more and more fossil fuels to extract the ore. Caldicott projects that within ten to twenty years, nuclear reactors will be counterproductive because of the amount of fossil fuel it will take to mine the remaining uranium. In addition to air pollution, nuclear power plants also emit radioactive gases and materials that have the potential
Facts, data, expert opinion: a) Low Pollution such as air pollution, water pollution - Nuclear power also has a lot fewer greenhouse emissions. It has been determined that the amount of greenhouse gases have decreased by almost half because of the prevalence in the utilization of nuclear power. Nuclear energy has the least effect on nature since it doesn’t discharge any gasses like methane and carbon dioxide b) Low Operating Costs - The cost of the uranium, which is utilized as a fuel in this process, is low. Also, even though the expense of setting up nuclear power plants is moderately high, the expense of running them is quite low. The normal life of nuclear reactor is anywhere from 40-60 years, depending on how often it is used and how it is being
Nuclear power produces fewer carbon emissions than traditional energy sources because energy is not produced by burning molecules but splitting atoms. ‘An energy mix including nuclear power has the lowest impact on wildlife and Ecosystems’ as shown by a Conservation Biology paper. Consequently, greenhouse gas emissions have reduced by nearly half which shows the benefits and popularity of nuclear power use. Nuclear power has many environmental benefits such as small waste production, leaves no adverse effect on water, land or any habitats. By reducing fossil fuel consumption and switching to Nuclear Energy, we will sustain the environment, quality of air, improving the overall quality of
Nuclear fission can be similar to nuclear fusion for example they both release heat energy. However, in nuclear fusion: • two nuclei must join together • Extremely high temperatures are needed. To develop further: Nuclear fusion is the joining of smaller nuclei to make larger ones. For example; Deuterium and Tritium form to make a bigger and heavier nucleus and Helium releases a lot of energy. Nuclear fusion also happens in stars..
Nuclear weapons have only been used practically twice in history, which occurred in the Japanese cities of Hiroshima and Nagasaki. From the nuclear weapons being executed on the two Japanese cities, over 210,000 casualties were reported. If nuclear weapons were ever used in modern day, the result would be globally catastrophic. As contemporary nukes are more powerful and have bigger abilities, their effects could put billions at risk of famine and death. Nuclear energy can completely disrupt agricultures and environments.
Nuclear energy only creates minimal negative effects to the environment. Nuclear energy produces steam and low levels of carbon dioxide. Nuclear energy is also beneficial seeing that it produces a large amount of energy for a low cost. Nuclear reactors generate energy at a lower cost than oil, gas or coal. This nuclear energy will be a stable source of energy seeing that it is a base load source and it is synergistic with other renewable resources.
In this diagram, a neutron is absorbed by a uranium-235 nucleus, as a result, it turns of a small period of time to an excited uranium-236 nucleus, with the excitation energy provided by the kinetic energy of the neutron plus the forces that bind to the neutron. The uranium-236 then splits into two, smaller, lighter, fast-moving elements (these are known as fission products) and releases three free neutrons as well as gamma rays. Fusion and fission are nuclear reactions. Fusion is the binding of two atoms to produce a heavier atom while fission is splitting of an atom. Fusion releases more energy than fission and powers the stars.
In this day and age where energy is one of the greatest factors in world events, it is unsurprising to see nuclear energy, the bridge between fossil fuels and renewable resources, argued for and against so fiercely. Yet under this umbrella term of “nuclear energy” that people enjoy throwing around, there are two wildly different forms of energy. Things that perhaps shouldn’t be lumped together so haphazardly. Those are Nuclear Fission and Nuclear Fusion.
Nuclear energy may be the solution that eliminates our concern for energy production in the future, but it still remains a huge issue for the environment. Despite its wide use in many developed countries, nuclear energy poses many threats to both the
Probably words like radiation, mutations and Homer Simpson pop into your head. However, that is not the case. According to Mark A. Jones, Director of Nuclear Operations and Engineering at Hutchinson Island Nuclear Power Plant, during our interview stated: “Nuclear energy compared to solar energy brings less of an impact because nuclear energy doesn 't emit air pollution unlike other forms of energy. It also only needs the fraction of land the salon energy needs and self-contain its own waste from polluting the environment.”
Helen Caldicott’s “Nuclear Power is Not the Answer” In the book-introduction “Nuclear Power Is Not the Answer,” Helen Caldicott argues that the government should stop developing nuclear power as an energy source. Supporting her point, she gives the following reasons: the nuclear energy is not efficient, not safe, not renewable and not environment-friendly. The author explains that in the process of nuclear electricity production, a lot of greenhouse gas and other pollutants are released.
Nuclear energy is something that we`ve all heard about. It carries risk and potential. When an atom (Uranium and Plutonium in nuclear power plants) is bombarded by neutrons, it can be split, causing fission. This fission releases more neutrons, which causes a chain reaction. Nuclear power plants use this use the heat that is created by fission to heat water that spins their turbines (“Nuclear Energy”).
Ever since Einstein first penned his famous equation, E = mc2, showing the world that there is energy stored in matter waiting to be harvested, mankind has been searching for new ways to free it. Initial work towards this goal led to the development of nuclear fission, the pinnacle of which was the successful Trinity Test in 1945. As time went on the technology was improved upon, resulting in nuclear power plants and more powerful weapons. Still, there was a desire for a more efficient, less dangerous, and more powerful means of extracting energy from matter. This desire was met with nuclear fusion.
Nuclear fusion and nuclear fission are two very different types of nuclear reactions that result in release or absorption of energy. Nuclear fusion is the reaction in which two or more smaller/lighter nuclei are combined together under extremely high pressure and temperatures to form one heavier and bigger nucleus of a new element with a higher atomic number. A significant example of where nuclear fusion occurs is in stars. Stars are fuelled by the atomic reactions of nuclear fusion and the collisions release massive amounts of energy which make the stars so hot and shine so brightly. The sun is powered by nuclear fusion in its core and it converts 620 million metric tons of hydrogen into helium every second.
