One common misconception is that fission is the only nuclear reaction that releases energy <\/strong>and fusion is the only nuclear reaction that absorbs energy<\/em>, a misunderstanding that Fission & fusion For GATE aims to correct. This understanding is incorrect because both reactions can release or absorb energy, depending on the specific reaction and the masses of the nuclei involved, a point emphasized in GATE.<\/p>\n To clarify, fission <\/strong>is a process in which an atomic nucleus splits into two or more smaller nuclei, along with a few neutrons and a large amount of energy, a process detailed in Fission and fusion For GATE. This process releases energy when the nucleus that undergoes fission has a mass greater than the sum of the masses of the resulting nuclei, a concept critical to Fission & fusion For GATE.<\/p>\n On the other hand, fusion <\/strong>is the process where two light atomic nuclei combine to form a heavier nucleus, also releasing or absorbing energy in the process, studied in for GATE. Energy is released in fusion when the resulting nucleus has a lower mass than the sum of the masses of the nuclei that fuse, a key aspect of Fission and fusion For GATE.<\/p>\n The accurate explanation lies in the mass-energy equivalence principle<\/em>, given by Einstein’s equation Therefore, it’s essential to understand that both fission and fusion reactions can release energy, and the notion that fission is the only energy-releasing nuclear reaction, while fusion only absorbs energy, is misleading and incorrect, a clarification provided by Fission and fusion For GATE.<\/p>\n Nuclear power plants utilize controlled fission reactions <\/strong>to generate electricity on a large scale, an application of Fission & fusion. These plants operate by harnessing the energy released from the splitting of heavy atomic nuclei, typically uranium-235 <\/em>or plutonium-239<\/em>, a process related to Fission & fusion For GATE.
