Nuclear power is a type of nuclear technology involving the controlled use of nuclear fission to release energy for work including propulsion, heat, and the generation of electricity. Nuclear energy is a clean, safe, reliable and competitive energy source. A small amount of matter creates a large amount of energy. A lot of energy is generated from a single power plant. Nuclear plants help regions meet air pollution standards and also reduce the cost of air pollution control for emitting facilities. As per the reports in 1998,it has been calculated the emission of the greenhouse gas has reduced for nearly half due to the popularity in the use of nuclear power. Of all energy sources, nuclear energy has perhaps the lowest impact on the environment especially in relation to kilowatts produced because nuclear plants do not emit harmful gases, require a relatively small area. Nuclear energy is an emission-free energy source because it does not burn anything to produce electricity. Nuclear power plants produce no green house gases. Nor does nuclear energy produce carbon dioxide or other greenhouse gases suspected to cause global warming. No doubt, nuclear energy has made its way towards the future but like other sources of energy, it also suffers from some serious drawbacks.
The main drawback and what makes it more dangerous is it safe to use the responsibility rests with the people. Irresponsible decisions can lead to accidents at nuclear power plants. The waste produced by nuclear reactors needs to be disposed off at a safe place since they are extremely hazardous and can leak radiations if not stored properly. There is a great deal of radiation danger associated with Nuclear energy. Nuclear waste from nuclear power plant creates thermal(heat) pollution which may damage the environment. The waste produced remains 'active' over many years and disposing it safely is a an issue which needs to be addressed properly. Any disaster at a nuclear power station would be much worse than disaster at another type of power station. Uranium which is a main raw material of nuclear technology is used in the process of fission because it's a naturally unstable element. Unfortunately, this means that while the uranium is being mined, transported and transformed into the contained pellets used in the fission chamber it is at risk of splitting on its own. This releases harmful radiation into its surroundings, and can be harmful to those handling the material. Runoff from the uranium mines poses a dangerous health risk and possible contamination to water tables. So, the nuclear technology has its own advantages and disadvantages.
