GENERAL KNOWLEDGE

Detailed explanation-1: -Fission occurs when a neutron slams into a larger atom, forcing it to excite and split into two smaller atoms-also known as fission products. Additional neutrons are also released that can initiate a chain reaction. When each atom splits, a tremendous amount of energy is released.

Detailed explanation-2: -Nuclear fission is the splitting of the nucleus of an atom into nuclei of lighter atoms, accompanied by the release of energy, brought on by a neutron bombardment.

Detailed explanation-3: -When a U-235 nucleus absorbs an extra neutron, it quickly breaks into two parts. This process is known as fission (see diagram below). Each time a U-235 nucleus splits, it releases two or three neutrons. Hence, the possibility exists for creating a chain reaction.

Detailed explanation-4: -A neutron collides with a Uranium-235 atom. This extra neutron creates unstable Uranium-236 isotopes, which split almost instantly. This splitting produces heat, which is converted into energy for power, and it produces two neutrons which continue the process, called a chain reaction.

Detailed explanation-5: -Nuclear energy is released by an atom’s nucleus. During nuclear fission, the nucleus of an atom is split and energy is released. During nuclear fusion, nuclei combine and energy can also be released. When large fissile atoms, usually uranium 235 or plutonium 239, absorbs a neutron, a fission of the atom often results.
