![]() Nuclear fusion energy cannot be harnessed. Nuclear fission takes place on large-sized heavy atoms, whereas nuclear fusion combines two small-sized light atoms to make a heavy one. a Differentiate between nuclear fission and nuclear fusion. Harnessing Fission is a controlled phenomenon, and hence the energy can be harnessed. More energy is released compared to nuclear fission. Energy Release Less energy is released compared to nuclear fusion. In the case of nuclear fission, an atom divides into two or. One large isotope is created as a result of combining the nucleus. A notable difference between nuclear fission and nuclear fusion is that the former creates a chain reaction in which one single nuclear reaction results in one or more succeeding nuclear reactions. Nuclear fission and fusion involve the disintegration and combination of the elemental nucleus. Product Two smaller isotopes are created as a result of the division of the nucleus. To completely initiate a fission reaction a high velocity neutron is required together with a critical mass of fuel to sustain the chain reaction. Two low mass isotopes are the starting reactant of nuclear fusion. Reactant One heavy mass radioactive isotope is the sole reactant of fusion. When two atoms combine under suitable conditions, it causes a nuclear fusion. Comparison Table Parameters of Comparison Nuclear Fission Nuclear Fusion Meaning When two unstable atoms are bombarded with high-speed particles, they split into two, causing nuclear fission. Nuclear fusion is a type of nuclear reaction in which two or more light atoms are usually unstable combines with one another to form a larger atom with comparatively stable energy. Like bombarding with high energy beams or any such measures.
