Question: What are the sources of energy in nuclear fission and fusion?
Answer:Nuclear fission is when a heavy atomic nuclei, like Uranium 235, divides. Fission is triggered by free neutrons. Two of the products of this fission reaction are heat energy and free neutrons which go on to trigger more fission reactions in what is called a chain reaction. Most nuclear power plants make steam from the heat energy and use steam turbines to convert it to power.
Nuclear fusion is when two light atomic nuclei combine. combines hydrogen with hydrogen, which gives off more than three times as much energy as the fission of Uranium 235. Unfortunately current technology can only achieve fusion in situations where more energy is used to direct the hydrogen molecules into the high energy collisions necessary for fusion to occur, then is released by the fusion reaction.
