Difference between Fusion and Fission
Fusion and fission are two nuclear processes that have different outcomes and energy producing properties. Despite their similarities, both mechanisms of nuclear energy production have fundamental differences. In this article, we will explore the basic variations between fusion and fission.
Fusion
Fusion is a nuclear reaction that occurs when two or more nuclei come together to create a new heavier nucleus. In this process, energy is released as a result of the atomic nuclei fusion. It is the same reaction that occurs on the sun, where hydrogen atoms combine to form helium, and energy is released in the form of light and heat. In the laboratory, fusion is the process that powers nuclear weapons and potential clean energy sources. This process generally requires high temperatures (millions of degrees Celsius) and pressure to allows the atomic nuclei to come close enough to combine.
One of the key advantages of fusion is that it does not produce radioactive waste. Additionally, this process releases massive amounts of energy, and the fuel which is hydrogen, is relatively cheap and abundant in the Earth’s atmosphere.
Fission
Fission is the splitting of a heavier nucleus into two or more lighter nuclei. In this process, energy is released, and it is found in a variety of nuclear applications. Nuclear power plants use fission to create energy by heating water, producing steam, and using that steam to turn turbines(spinning generators). Similarly, fission occurs in nuclear bombs where it is used to produce massive amounts of energy in practically no time.
One of the principal disadvantages of nuclear fission is that it produces radioactive waste, which takes thousands of years to decay, hence requires to manage in specific ways to avoid harmful effects. Additionally, nuclear fission requires a specific fuel, which is radioactive and rare, and its mining creates environmental issues.
The Significant Variations between Fusion and Fission
There are several significant differences between fusion and fission. As mentioned earlier, fusion combines atomic nuclei, while fission splits them apart. Fusion does not produce long-term radioactive waste, while fission does. Moreover, fusion produces a high amount of energy and is considered the holy grail of clean energy, while fission has environmental impacts.
Another significant difference between the two nuclear processes is the amount of energy each can produce. Fission releases more energy than fusion. Still, this energy comes with the significant disadvantage of massive radioactive fallout and environmental contamination that requires long-term storage in controlled storage facilities.
In conclusion, both nuclear processes have differing advantages and drawbacks. Fusion holds the promise of nearly unlimited clean energy, while fission provides an existing tool for energy production. Nuclear technology and engineering continue to develop to achieve the balance between efficient energy production and safe environmental practises.
