Nuclear power, the use of exothermic nuclear processes to produce an enormous amount of electricity and heat for domestic, medical, military and industrial purposes i.e. “By the end of 2012 2346.3 kilowatt hours (KWh) of electricity was generated by nuclear reactors around the world” (International atomic energy agency Vienna, 2013, p.13). However, with that been said it is evident that the process of generating electricity from a nuclear reactor has numerous health and environmental safety issues.
The impact of nuclear power on the modern world has improved Various sectors of the economy and society .i.e. Food and Agriculture, Insect control, Food Preservation, Water Resources, Military, Medicine, Research and Industry. “In 1911 George de Hevesy conducted the first application of a radioisotope. At the time de Hevesy was a young Hungarian student working in Manchester with naturally radioactive materials. Not having much money he lived in modest accommodation and took his meals with his landlady. He began to suspect that some of the meals that appeared regularly might be made from leftovers from the preceding days or even weeks, but he could never be sure. To try and confirm his suspicions de Hevesy put a small amount of radioactive material into the remains of a meal. Several days later when the same dish was served again he used a simple radiation detection instrument - a gold leaf electroscope - to check if the food was radioactive. It was, and de Hevesy's suspicions were confirmed.
History has forgotten the landlady, but George de Hevesy went on to win the Nobel Prize in 1943 and the Atoms for Peace award in 1959. His was the first use of radioactive tracers - now routine in environmental science” (World Nuclea...

However, utilizing nuclear power has several implications. One of the most severe is that nuclear technology produces a great amount of toxic waste that remains radioactive for thousands of years. Thus, the waste must be disposed of in a safe manner so to avoid the contamination of future generations.
Non-renewable resources such as fossil fuels have been used up by society on a daily basis and have forced the world to find a new, clean energy source. The rising price of oil and the constant emission of carbon dioxide are proof that in the future our lives will be much harder to live. One answer to this problem is nuclear power, which has shown its efficiency during the times of World War II but has not been used commercially due to the challenges of dealing with nuclear waste and proliferation. In today?s modern era, nuclear power has been used in liquid metal fast breeder reactors, reactors that use uranium-238 to produce plutonium-239.
After World War II, nuclear power became the world’s shining energy hope. Technically it is produced when neutrons split the nucleus of uranium atoms releasing heat which is used to boil water and produce the steam that drives a plant’s turbines. Nuclear...
In addition to the potential dangers of accidents in generating stations, nuclear waste is a continuing problem that is growing exponentially. Nuclear waste can remain radioactive for about 600 years and disposing these wastes or storing them is an immense problem. Everyone wants the energy generated by power plants, but no one wants to take responsibility for the waste. Thus far, it is stored deep in the earth, but these storage areas are potentially dangerous and will eventually run out. Some have suggested sending the waste into space, but no one is sure of the repercussions.
Nuclear power, or nuclear energy, is the use of exothermic nuclear processes,[1] to generate useful heat and electricity. The term includes nuclear fission, nuclear decay and nuclear fusion. Presently the nuclear fission of elements in the actinide series of the periodic table produce the vast majority of nuclear energy in the direct service of humankind, with nuclear decay processes, primarily in the form of geothermal energy, and radioisotope thermoelectric generators, in niche uses making up the rest. Nuclear (fission) power stations, excluding the contribution from naval nuclear fission reactors, provided about 5.7% of the world's energy and 13% of the world's electricity in 2012.[2] In 2013, the IAEA report that there are 437 operational nuclear power reactors,[3] in 31 countries,[4] although not every reactor is producing electricity.[5] In addition, there are approximately 140 naval vessels using nuclear propulsion in operation, powered by some 180 reactors.[6][7][8] As of 2013, attaining a net energy gain from sustained nuclear fusion reactions, excluding natural fusion power...

Nuclear power has grown to be a big percentage of the world’s energy. As of January 18, 2013 in 31 countries 437 nuclear power plant units with an installed electric net capacity of about 372 GW are in operation and 68 plants with an installed capacity of 65 GW are in 15 countries under construction. As of end 2011 the total electricity production since 1951 amounts to 69,760 billion kWh. The cumulative operating experience amounted to 15, 15,080 years by end of 2012. (European Nuclear Society) The change that nuclear power has brought to the world has led to benefits in today’s energy’s usage.
Around 1894, scientists discovered that by bombarding a radioactive substance with neutrons, a highly powerful energy could be produced. This is ionizing radiation, which is strong enough to rip the electrons from the nucleus of an atom, hence the name “nuclear energy.” over a century later, nuclear substances are harnessed in order to provide energy. However, nuclear energy is not only discussed amongst scientists, but anyone fearing the safety and future of the environments surrounding the area where a nuclear power plant is implemented.
On April 26th 1986, the world’s worst nuclear accident occurred at the Chernobyl Nuclear Power Plant in Ukraine. The explosion sent a ‘cloud of radiation’ throughout the area, including Belarus, and much of the western Soviet Union and Europe, releasing 400 times more than the atomic bombing of Hiroshima. This is because a nuclear power plant contains a lot more nuclear material than an atomic bomb.

Nuclear energy has been identified as an effective source of electrical power that is being capitalized upon around the world. While nuclear power offers benefits, such as sustainable energy, the risks associated with it including nuclear accidents, proliferation, and terrorism make it a gamble. The probability of such events occurring is low, but the impact they could cause is immense. However, the irreversible effects of climate change override the concerns with nuclear power which can be alleviated by heightened security and international efforts.
The use of nuclear power in the mid-1980s was not a popular idea on account of all the fears that it had presented. The public seemed to have rejected it because of the fear of radiation. The Chernobyl accident in the Soviet Union in April of 1986 reinforced the fears, and gave them an international dimension (Cohen 1). Nevertheless, the public has to come to terms that one of the major requirements for sustaining human progress is an adequate source of energy. The current largest sources of energy are the combustion of coal, oil, and natural gas. Fear of radiation may push nuclear power under the carpet but another fear of the unknown is how costly is this going to be? If we as the public have to overcome the fear of radiation and costly project, we first have to understand the details of nuclear energy. The known is a lot less scary then the unknown. If we could put away all the presumptions we have about this new energy source, then maybe we can understand that this would be a good decision for use in the near future.
The energy industry is beginning to change. In today’s modern world, governments across the globe are shifting their focuses from traditional sources of power, like the burning coal and oil, to the more complex and scientific nuclear power supply. This relatively new system uses powerful fuel sources and produces little to no emissions while outputting enough energy to fulfill the world’s power needs (Community Science, n.d.). But while nuclear power seems to be a perfect energy source, no power production system is without faults, and nuclear reactors are no exception, with their flaws manifesting in the form of safety. Nuclear reactors employ complex systems involving pressure and heat. If any of these systems dysfunctions, the reactor can leak or even explode releasing tons of highly radioactive elements into the environment. Anyone who works at or near a nuclear reactor is constantly in danger of being exposed to a nuclear incident similar to the ones that occurred at the Chernobyl and Fukushima Daiichi plants. These major accidents along with the unresolved problems with the design and function of nuclear reactors, as well as the economic and health issues that nuclear reactors present serve to show that nuclear energy sources are not worth the service that they provide and are too dangerous to routinely use.
One of the greatest events of twentieth century was the use of radioisotope as a source of energy and as medical and industrial tools. Using radioactivity has been a global issue owing to its very nature. When it is used for peaceful purposes, it is a triumph of science because it can solve energy problems in the form of nuclear energy but the side effects in the form of harmful radiation and harmful radioactive waste is the real limitations of science. This essay will attempt to analyze the application of science in the use of radioactivity and radioactive isotopes and how science is not so effective in dealing with the side effects.
The greatest disadvantages of nuclear energy are the risks posed to mankind and the environment by radioactive materials. ‘On average a nuclear plant annually generates 20 metric tons of used nuclear fuel cla...
