Advantages And Disadvantages Of Nuclear Energy

　　　　On contrast, opponents hold different conceptions, they do not regard nuclear energy as a green and clean source of energy. According to Ross(2007), a news director for the National Urban League, fuel rods at every nuclear plant leak radioactive and harmful gases to atmosphere, and it is collectively releasing millions of curies annually. As a matter of fact, the essential raw material for nuclear nuclear power is uranium, which is a dangerous radioactive element. Opponents also claims that uranium tailing which is byproduct of the procession of getting energy are being inappropriately disposed, which make the situation even worse. On the other hand, after the tragedies of nuclear energy in Chernobyl, three mile island and other district, some people have become more and more impregnable to believe the nuclear energy is dangerous. Dr.

Firstly, nuclear waste is hard to dispose of. Unlike other power sources, nuclear waste is still not known about how to dispose of. This is a problem because the waste emits radiation, which can leak into the environment. Chernobyl is

Unfortunately, there are many disadvantages associated with the combustion of coal energy. For example coal releases a tremendous amount of carbon emissions that negatively contribute to climate change and global warming. Coal burning is considered not environmentally friendly due to the large production of harmful by-products such as nitrogen, carbon dioxide and sulfur dioxide. This pollution can lead to other major problems for example acidic rain, as well as hazardous health risks to our eco-systems. Globally, scientists agree that the release of greenhouse gases are contributing to the earths rise in temperature, which leads to rising sea levels, disappearing glaciers and change in annual weather patterns. The main problem associated with

When asked about the number of active nuclear power plants most people in the United States would probably guess a like ten or twenty when in actuality “there are currently sixty one commercially operating nuclear power plants with ninety nine nuclear reactors in thirty states in the United States. Thirty-five of these plants have two or more reactors.”(eia.gov) In America nuclear power has a stigma of just negative effects among these is ,“radioactive waste produced by nuclear reactors which needs to be disposed of at a safe place since they are extremely hazardous and can leak radiations if not stored properly. Such kind of waste emits radiations from tens to hundreds of years. The storage of radioactive waste has been major bottleneck for the expansion of nuclear

While there are plenty of benefits to using nuclear power, there are numerous disadvantages that also come with its use. There have been nuclear incidents throughout history that have caused many questions to be raised about how safe nuclear energy really is. One of the most notable accidents is the one that happened at the Chernobyl nuclear plant in Ukraine. An explosion at the plant destroyed the reactor core which in released radioactive material into the atmosphere. This accident has been considered the largest uncontrolled radioactive release into the environment ever. This hasn’t been the only incident in history that has turned head though. There was an earthquake in Japan that caused the Fukushima Daiichi nuclear plant’s core to experience a meltdown. Because of the 9.0 magnitude earthquake, a tsunami caused water to seep into the plant generators which lead to temperatures and reaction rates being uncontrollable and ultimate the release of tons of radioactive waste into the environment. Three Mile Island, a nuclear power plant located in Pennsylvania, is considered the most significant accident that has happened on American soil when it comes to dealing with nuclear energy. Numerous mechanical and human errors lead to a chain of events that no one could have seen coming that resulted in a partial meltdown of a nuclear reactor. It’s because of this accident that no new nuclear power plants have been constructed in the United States. The impact that the Three Mile

TMI has provided electricity since 1979. The Exelon Corporation might shut down the plant. There are many pros to nuclear power and many cons. I think we should keep the plant open. Here’s why, if we close the plant, employees will lose their jobs. Also, nuclear energy is clean energy. If we close TMI down, then it would take years to build a new kind of energy source.

At this point, it may seem like nuclear power is just a slightly more dangerous method of producing electricity than a more commonly used method like coal-burning. However, environmental impact and efficiency are the areas where nuclear power shines the brightest. Feiveson (2009), a self-titled skeptic of nuclear power, wrote, “Compared to coal-generated electricity in particular, it [nuclear power] is relatively clean, producing almost no emissions” (p. 60). Because turning water into steam is the main method of producing electricity with nuclear power, it is apparent why nuclear power plants do not release very many toxins into the environment. Harrison, Hester, & Walls (2011) stated that during the normal functioning of a nuclear power

Nuclear power is composed with uranium ore that is extracted from a rock where uranium is made out of. Uranium is typically the most common element found, that it appears more often than silver and gold. Usually found in the earth’s crust , soil, rivers, rocks and even oceans. The use of uranium is to generate heat, produce nuclear weapon, armor plating and as a colorant for uranium glass. Anyways nuclear energy is use to create electricity, reactors and produce power plants. The way that nuclear produces electricity is the same process as every power plant, but before anything the nuclear energy must be released from the atom. This then goes into a nuclear fission that splits the atoms to than create energy.

The entire process, from retrieval to the actual combustion of the carbonized matter, produces pollution. As previously mentioned, the mining of coal results in the disturbance of topsoil and watershed, and this often leads to the pollution of waterways as the topsoil makes it way into the bodies along with other toxic material. Coal dust, a result of mining the fossil fuel, ends up in the waterways along with the topsoil and finds its way into the groundwater. The ecological abuse does not stop there, as, according to Union of Concerned Scientists, the burning of coal is “a leading cause of smog, acid rain, and toxic air pollution,” and the Sierra Club, Conserve Energy Future, as well as every science book I’ve been assigned in middle school, have similar outlooks. Among all of the pollutants coal has to offer for our planet, sulfur dioxide, nitrogen oxides, mercury, and the various compositions of ash are what is most abundantly emitted into the air. These, of course, contribute to acid rain, global warming, smog, health problems, or all of the

Pollution is another topic with both pros and cons. Fossil fuels release harmful pollutants into the air such as carbon dioxide and sulfur dioxide. Nuclear power does not release any of those toxins into the atmosphere. However, a pollution problem with nuclear energy is thermal pollution, where a plant’s “hot effluents” are put into a nearby body of water, and raise the temperature by a small amount but enough to cause a disturbance in the ecosystem of the lake or reservoir. Nevertheless, this could easily be solved by cooling the effluents before releasing them into the water. The other problem facing nuclear energy is waste disposal. Nuclear waste is radioactive and very dangerous. Therefore, it must be kept buried and sealed up for a long period of time until the radioactivity dies [Plasma-Material]. One positive fact about nuclear energy that is not disputed is its abundance.

The only two nuclear weapons ever used in history killed an estimated 226,000 people.These two bombs are a prime example of the fact that nuclear power is dangerous and should not be handled carelessly.Not only are nuclear weapons dangerous,but nuclear power plants and reactors are also a threat to the human race.Nuclear power provides about 11 percent of the world’s electricity every year which means we can not completely get rid of it due to the amount of energy it produces.On the other hand nuclear weapons are dangerous and do not help the human race in any way therefore they should all be destroyed and never used again.Not only will nuclear weapons eventually wipe out the human race,but there are also huge effects to the environment that

Nuclear power is a very intriguing alternative energy source. I find that the more that I learn about nuclear power, the more I realize that my knowledge has just skimmed the surface of what there is to know about the energy source. The most surprising fact about nuclear power that Mycle Schneider mentioned in one of his interviews was that all nuclear reactors have a life expectancy. On average, the typical nuclear reactor has an operational design basis of approximately 40 years. As of right now, the average age of all operational nuclear reactors worldwide is approximately 28.5 years old. This means that within the next decade, we could begin to see the majority of these nuclear plants being decommissioned. Therefore, when the time comes,

Since the concern of not having the right amount can no longer be considered a problem, we must now investigate the accessibility of the wide variety of alternatives energy sources. Alternative energy sources may or may not be renewable. Alternatives such as wind, solar, hydro, and thermal will always be replenishing so the problem is not accessing these alternatives but actually going out and putting in the effort to utilize these resources. All that is required of people or companies is to build the necessary equipment required to capture the designated alternative energy source. As illustrated by Berinstein, “wind power systems can be designed in many ways. Most systems include a rotor with two or three blades…and an electrical generator…” (100). People do not even have to follow a specific design; designers have the ability to design their products based on the needs of the people wanting to buy them. They can be designed for high output, land conservation or even for minimal maintenance. Also illustrated by Berinstein, “Small turbines are simpler…These systems require less maintenance, but of course, they produce less energy” (100). This specific system could have been designed for unused terrain which means it is not easily accessible for persistent maintenance checkups. Since many alternative energy sources are renewable

Almost all human activities rely on some form of energy. There are various sources of energy in the world and the most commonly used is coal. However, due to a decline of coal deposits, need for alternative sources of energy have gained popularity in the past few decades. There are various sources of energy, which have been used as alternatives for example hydropower, wind power, geothermal energy, and the most important of all, nuclear energy. As the world’s population expands, so does demand for nuclear energy. With technological advances, the utilization of nuclear energy has become ubiquitous in peoples lives. The widespread use of nuclear energy has been a controversial issue for many years as there have been a lot of problems that arose with its usage. Nuclear Power is an essential and a valuable energy source yet still poses many significant risks globally.

In terms of the drawbacks, nuclear power causes health concerns. The waste of nuclear power is dangerously radioactive and remains the same for thousands of years. When the waste first comes out of the reactor, it is so toxic that if a person stood in a few meters of it while it was unshielded, he would receive a lethal radiative dose within a few seconds and would die of radiation poisoning within a few days.
