9/19/2023 0 Comments Nuclear fusion vs fission![]() With the funding taps open, significant progress has recently been made to overcome a litany of scientific challenges-not least the enormous temperatures required to trigger a fusion reaction. From a safety standpoint, nuclear meltdown is practically impossible, and only a small volume of relatively short-lived radioactive waste is produced.įusion’s incredible promise is being pursued by a consortium of global physicists supported by China, Russia, the United States, and several European governments. When this happens, an immense amount of energy is released: four times as much as fission, and nearly 4 million times greater than the burning of fossil fuels. Whereas nuclear fission-the process that drives conventional nuclear power plants-involves the splitting of atoms, fusion takes place when a pair of light atomic nuclei combine to form a single heavier one. With sweeping international collaboration and billions of dollars of public and private investment, scientists have recently made a series of meaningful advances in both the duration and power output possible from fusion reactions. This is because the process of nuclear fusion is highly complex and requires temperatures and pressures that can only be attained through powerful lasers or magnetic fields.That could be about to change. Why did it take so long for this success?įor decades, scientists have sought to achieve nuclear fusion, yet it has taken a long time to be successful. In addition, building and operating a nuclear reactor tends to cost less compared to other sources because they have higher efficiency rates coupled with longer lifespans (upwards of 50 years). Moreover, nuclear fusion produces much more power than solar and wind energy due to its use of hydrogen atoms as fuel in a controlled reaction which releases tremendous amounts of energy in the form of heat and light this process is also safer than traditional fission reactors since there is no associated risk of meltdown or radiation leakage.įurthermore, the waste produced by nuclear fusion can be safely stored underground for thousands of years with minimal environmental risks.Īdditionally, compared to other renewables such as solar and wind, nuclear fusion requires relatively small amounts of land area due to its high efficiency rate, making it ideal for densely populated urban areas where land availability may be limited but demand remains high. It does not produce any greenhouse gases or air pollution, making it an attractive option for large-scale electricity generation without contributing to global warming or climate change. Nuclear fusion is a clean energy source that has many advantages over other forms of renewable energy.

Thirdly, while both processes require large amounts of energy to initiate and sustain them, significantly less energy is needed to start and maintain a fusion reaction as opposed to a fission one this makes constructing and operating reactors using nuclear fusion technology simpler and cheaper than those using traditional nuclear fission technology.įinally, since there are no long-lived radioactive isotopes generated during the process of nuclear fusion, it is considered safer than traditional uranium or plutonium-based power plants due to the reduced risk of radiation exposure or contamination. ![]() How does it differ from existing nuclear fission technology? This could lead to increased economic growth in many parts of the world while helping us move towards a greener future. By reducing our reliance on fossil fuels and providing an alternative source of clean energy, countries could save money on fuel costs while creating jobs related to the research and development of new technologies related to nuclear fusion. The economic benefits of nuclear fusion should also be considered. This would reduce dependence on fossil fuels and help countries meet their objectives and SDG targets. ![]() Nuclear fusion involves combining two or more atomic nuclei to generate energy and could provide an almost inexhaustible source of clean, safe, and affordable power. Why is success in nuclear fusion important?Īchieving success in nuclear fusion is of utmost importance for the world, as it has the potential to revolutionise energy production. In an interview with India Today, Archana Sharma, CMS Experiment Principal Scientist, Physics Department of CERN, Switzerland, highlighted what the success of fusion reactions means for the world and how it is different from existing nuclear energy. ![]()
