Generate a large amount of energyNuclear reaction releases more than a million times the energy than hydropower or wind energy. Therefore, large amounts of electricity can be generated. Currently, there are about 10-15% of the world's electricity is generated by nuclear power. You know with a kilo of uranium-235 can produce electrical energy amounts equivalent to 1,500 tons of coal. Green energy sourcesThe biggest advantage of this source of energy is not create the greenhouse gas emissions (such as carbon dioxide, methane, ozone, chlorofluorocarbon) in nuclear reactions. Greenhouse gas emissions are a major threat to the habitats they cause global warming and climate change. Nuclear reaction does not produce emissions, should have little impact on the environment. Do not contaminate the airThe burning of fuels such as coal generates carbon dioxide and smoke. It is a threat for the environment as well as human life. Production of nuclear power does not emit smoke. Therefore, it does not pollute the air directly. However, the radioactive waste is a big problem today. Independent fuelNuclear reactors use enriched uranium as fuel. Fission of uranium in small amounts can make a great energy. Currently, uranium reserves are found on earth are expected to meet the needs of 100 years from now. Use this energy could make many countries can independently about energy and not dependent on the mining of the coal as fuel.If there are no human error or accident and natural disaster, the nuclear reactor will operate very effectively in a long time. In addition, after the construction, the operation of the plant requires very little labor. Disadvantages of nuclear energyRadiationThe release of harmful radiation at random is one of the biggest limitations of nuclear energy. Fission frees the radiation, but they are controlled in a nuclear reactor. If the measures of safety cannot be guaranteed, the radiation can expose the environment will lead to serious impacts to the ecosystem and humans. Unable to reproduceAlthough they make up a large amount of energy, the nuclear reactor still depends on uranium. This is a fuel that can be exhausted. The exhaustion of it can cause a serious problem. The reactors will be decommissioned, they will still occupy a large area of land and pollute the environment. Development of nuclear weaponsThis energy can be used for the production and dissemination of nuclear weapons. Nuclear weapons use fission, fusion, or a combination of both responses for the purpose of destruction. It is a major threat to the world as they can cause a large scale destruction. Their effects can affect many generations (for example, the atomic bombings in Hiroshima and Nagasaki, Japan). The huge construction costsHowever, a large amount of energy can be produced from a nuclear power plant, but it requires huge investment costs. Need about 10-15 years to construct a power plant nhên seeds. The construction of a nuclear power plant might not be feasible. Nuclear wasteThe waste is generated after nuclear fission contain unstable elements and high radiation. It is very dangerous for the environment and human health and will survive for a long period of time. It should be handled with care and is separated from the living environment. Radioactivity of this element will fall for a while, then decomposes. Therefore, one must be stored and handled with care. The radioactive elements in a long time is very difficult. Nuclear power plant accidentsTo this, there have been two accidents in nuclear power plants inflicted: Chernobyl disaster occurred at the Chernobyl nuclear power plant (1986) in Ukraine, and the nuclear disaster Fukushima Daiichi (2011) in Japan After the incident, a large amount of radiation has been released into the environment, leading to the loss of people, nature and the land. One cannot deny the possibility of repeating the disaster in the future. Transport of fuels and wasteThe transport of uranium fuel and the radioactive waste is very difficult. Uranium emits some radiation, so it needs to be handled carefully. The waste of nuclear production process is also more dangerous and needs to be better protected. All the means of transport they ensure the international safety standards. Although no accidents or spills would be statistically, but the carriage was still challenging.
