IntroductionReducing GHG emissions and solving climate change remains a challenge, as the world faces the depletion of fossil fuels, but the demand for The energy remains constant. increasing over these years. An effective approach to solving the problem is to switch to renewable energy, or even nuclear energy. The more people oppose the science of nuclear energy following the Fukushima accident in 2011, the more they support the development of renewable energy. Compared to renewable energy, nuclear energy has been widely used for decades with mature and applicable technology. In total, more than 400 operating nuclear power plants in 30 countries produced 2.62 trillion kWh, which provided 13.5% of the world's electricity in 2010 (TN&T.S., 2012). China has decided to turn to nuclear power rather than natural gas and fossil fuels to meet the nation's electricity expansion – "mainland China has 20 nuclear reactors in operation, 28 under construction and “others are about to begin construction,” according to the World Nuclear Association (2014). ).Yet the raw material used to produce nuclear electricity, uranium, is a non-renewable resource, and nuclear power plants have negative impacts on the environment, which the essay elaborates on below. at the beginning of the 20th century. The atom held enormous energy capacity - uranium (uranium-238 and uranium-235) is transformed into solid ceramic pellets packed into long vertical tubes for use. In the reaction, the pellets are bombarded with neutrons, which causes the uranium atoms to split and release heat and neutrons, then the neutrons collide with other uranium atoms and release additional heat ... middle of paper..... . : April 8, 2014.
