Nuclear Energy Introduction Essay

Nuclear energy is the energy that holds together the nuclei of atoms. Atoms are the most simple blocks that make up matter. Every atom has in its center a very small nucleus. Normally, nuclear energy is hidden inside the atoms. However, some atoms are radioactive and send off part of their nuclear energy as radiation. Radiation is given off from the nucleus of unstable isotopes of radioactive substances.

Nuclear energy can also be freed in two other ways: nuclear fusion and nuclear fission. Nuclear fusion is the combining of two light atoms into a heavier one and nuclear fission is the splitting of a heavy atom. Both ways make big amounts of energy. They sometimes take place in nature. Fusion is the source of heat in the sun. Fission is also used in nuclear power plants to make electricity. Both fusion and fission can be used in nuclear weapons.

Nuclear power generates a number of radioactive by-products, including tritium, cesium, krypton, neptunium and forms of iodine. [1]

Nuclear energy production and use has been a controversial topic over the years. This has always been dictated by the history of the nuclear energy and also on the current energy demands as well as environmental conservation demands. Countries should venture into nuclear energy production to help meet the rising energy demand, to help conserve the environment by avoiding pollution, and also as a long lasting replacement for the depleting fossil fuels sources of energy. There have been mitigation measures put in place to ensure that nuclear energy accidents like those of Chernobyl and Fukushima do not have a repeat. Countries should also cease from using the nuclear energy to make dangerous weapons of mass destruction.

Nuclear energy
Nuclear Power and its uses is a growing discussion in today‚Äôs era of technology. Australia is one of the developed countries where the demands of energy resources are increasing rapidly. Nuclear energy is coming up as a great alternative, but various factors support as well as oppose its growth. Some countries oppose the usage of nuclear energy because of the problems associated with its usage. Production and Maintenance of nuclear power is very expensive. Nuclear power is viewed as too dangerous, uneconomical, and not required. Although, nuclear energy has a potential hazard, but it is reliable in terms of efficiency, environmental impact and cost when compared with other sources of energy. Therefore, the increase in the…show more content…

Though renewable sources of energy are reliable but their output greatly depends on the environment. For example, cloudy days have no solar gain, hence no solar energy production. Quiet days mean no wind blows to drive wind turbines. Dams are primarily for flood control, so hydroelectricity production varies as dam water levels fluctuate.

Considering the case of Aswan Dam in Egypt not only caused thousands to loose their homes and lives but also ceased the fertile surrounding because of the yearly inundation of the Nile. Moreover, the subsequent silting up for the river destroyed much wildlife.

Due to Thermal Power Generation, 2500 million tons of coal each year is consumed to produce 38% of the electricity, While 61,000 tons of Natural Uranium will be used to generate the same amount of energy (World Nuclear Association, 2005) .
Secondly, nuclear energy source has a weak impact on environment than the Non-renewable resources. There is no doubt that use of fossil fuels leads to global warming. While, the amount of carbon dioxide in the atmosphere was only 0.028% five decades ago, now, as per American Petroleum Institute (1998) estimates it reached 0.036%. Additionally, burning of fossil fuels, especially coal, oil, and natural gases are the main causes for increase in pollution; especially air pollution. Several hazardous pollutants are produced by fossil fuels combustion: Carbon Monoxide, Nitrogen Oxides, Sulphur Oxides and
