Nuclear Energy Advantages And Disadvantages Essay
General Observations
Advantages
As global warming is currently a pressing issue that needs to be dealt promptly, nuclear power appears to be a good alternative to the conventional fossil fuel because it does not emit carbon dioxide or other greenhouse gases during electricity production.
Uranium is the common fuel used in nuclear power generation. Despite the fact that only 0.7% of the natural uranium is radioactive and is able to undergo fission using the current technology, the energy density (or energy per unit weight) of uranium is about 16,000 times higher than that coal. This reduces the cost for transporting and storing fuel for electricity generation [a].
Although uranium resource is not unlimited like solar or wind, it is more abundant than the coal reserve. The world’s present known uranium resource is 5.9 million tonnes and it is estimated that this reserve is enough to last for about 90 years. Further resources can be explored with higher price when the uranium runs out. Therefore, nuclear

If nuclear waste is not treated and disposed properly, nuclear leakage will cause risk to human health. Furthermore, in case of nuclear accidents, such as the Chernobyl nuclear disaster and the Fukushima nuclear disaster, the impacts could be disastrous. Apart from causing acute radiation sickness and long-term cancer risks to human [e], it also causes damage to the environment, genetic damage and undesired mutations to animals. In addition to radiation leakage, nuclear power stations could be a target for terrorists, which could potentially be a threat country. For example, it was reported that the terrorists from ISIS planned to use nuclear waste at a nuclear power station in Brussels in order to make ‘dirty bombs’ and carry out terrorist attacks. If this happens, the consequences could be serious
The Pros And Cons Of Nuclear Fission
354 Words | 2 PagesWhen the nuclei of Uranium-235 and Plutonium-239 undergo nuclear fission, they produce waste as a by-product, which is known as nuclear waste or “fission fragments”. (Leslie Corrice, 2015) This waste contains radioisotopes, which are radioactive isotopes that have long half-lives. This means that the radioisotopes are able to stay in the atmosphere for hundreds of thousands of years, which is extremely hazardous to the earth’s environment. Very commonly this waste contaminates water and ruins the quality of both air and soil, which in turn devastates the planet.
Pros And Cons Of Nuclear Power Plants
160 Words | 1 PagesPower 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.
The Pros And Cons Of Nuclear Power Plants
824 Words | 4 PagesOver 20 percent of the energy in the United States comes from nuclear energy power plants. (Rinkesh, 2018) They so their best to get as much energy to the country as possible, but there are those out there who don’t agree with them. While there are downsides to nuclear energy, the pros vastly outweigh the cons. Nuclear power plants are a great way to get energy because they don’t let out much pollution, are very efficient, and are very safe.
Argumentative Essay-Nuclear Energy Is Australia's Future
607 Words | 3 PagesNuclear Energy IS Australia’s Future Introduction: I wholeheartedly believe that Nuclear Energy will play an inevitably central role as a reliable energy source in Australia’s future. Australia must invest in Nuclear energy because coal and oil are becoming scarce, requires less fuel and is eco-friendly. Australia is blessed with the world’s largest known uranium resources (a bountiful 38% according to Professor Mary O’Kane NSW Chief Scientist and Engineer). ANSTO (Australian Nuclear Science and Technology Organisation) reports: ‘No country of Australia’s economic size or larger is without nuclear power’.
What Are The Pros And Cons Of Nuclear Energy
1790 Words | 8 PagesNuclear energy has numerous world benefits that other forms of energy creation just don’t, and its pros are truly unprecedented by any other source of energy. Nuclear power plants are inexpensive to run, which means they can easily be maintained and sustained at a low cost. And while the reactors themselves may be expensive, with government grants the materials can be much more easily purchased and built. The most expensive part of the nuclear reactor process is the uranium, which again, isn’t hard to get as it’s used in few other applications and can be acquired through government programs. Additionally, the energy emitted from these power plants compared to their cost is immense and an extremely worthwhile investment for governments and private businesses.
Atomic Bomb Pros And Cons Essay
861 Words | 4 PagesThe atomic bombs were that were dropped on Hiroshima and Nagasaki in Japan took place on August 6, 1945 and August 9, 1945. There is a great deal of controversy regarding whether or not the Untied States should have dropped the bombs on the Japanese cities. Using the atomic bombs have both pros and cons that many people feel strongly about. Some believe that Japan was not close to surrendering and more causalities would have occurred during a land invasion if the bombs were not dropped. In contrast, there were also several other ways of of attempting to end war with Japan that could have been done besides using the bombs.
The Pros And Cons Of Nuclear Power
1230 Words | 5 PagesNuclear Power Support or Fear The global energy demand is increasing as years go by as there is a rapid growth of population in deed of power. Due to the high demand for energy, many people are opting to replace other forms of energy with nuclear power because of its safety, reliability, and sustainability. In addition, it is one of the cleanest carbon free sources of energy available in the world today. Nuclear power is the use of continuous nuclear fission to produce electricity and heat.

Nuclear Weapons In Fahrenheit 451, By Ray Bradbury
851 Words | 4 PagesIf the environment was exposed to even a relatively small nuclear weapon, studies show that devastating effects would take place against the world’s climate and decade long lasting effects on the ecosystems of the Earth. A small perception that can be used to see the effects of nuclear energy being exposed to the environment is the Chernobyl Disaster of 1986. To this day, there are still no inhabitants of the exposed areas inside Chernobyl, Ukraine, as those exposed can experience heavy vulnerabilities to cancer, diseases, and death. Just from the small accident in Chernobyl, there are still modern effects of the disaster. Things like birth defects, sights of mutated organisms, and sicknesses are still reported as a result from the mass leak of radiation.
Nuclear Waste Muller Summary
721 Words | 3 PagesMany fear that the high number of earthquakes in the region could cause a possible leakage. This would most definitely harm not only our environment but also eventually infiltrate our drinking water. What if a big earthquake released a portion of the nuclear waste before we could contain it again? This is where Muller does a great job of explaining to the reader that more research must go into leakage prevention rather than absolute containment. Muller uses mathematics and science to show how we have the possibility of being exposed to less radioactivity with the toxic waste, than if we never dug the uranium up in the first place.
Persuasive Essay On Nuclear Energy
3678 Words | 15 PagesNuclear energy is one of the several alternative energy sources that have been introduced ever since. Nuclear energy’s various advantages entice many countries to start practicing it. One must consider the amount of energy generated by nuclear fuels, as they are highly-concentrated energy sources. Small uranium pellets, which are the most common form of fuel in generating nuclear energy, can generate as much electricity as a trainload full of coal does. In addition, nuclear power plants do not produce green house gases as byproducts.
