Explanation

Nuclear fission in a nuclear reactor is primarily initiated by neutrons. Neutrons are subatomic particles that have no electric charge, and they play a critical role in sustaining the nuclear chain reaction within a reactor. When a neutron collides with the nucleus of a fissile material, such as uranium-235 (U-235) or plutonium-239 (Pu-239), it can induce nuclear fission.

During the fission process, the nucleus of the fissile material splits into two or more smaller nuclei, releasing a significant amount of energy and additional neutrons in the process. These secondary neutrons can go on to cause further fission reactions in nearby fissile nuclei, leading to a self-sustaining chain reaction, which is the basis for the energy production in nuclear reactors.

So, in summary, neutrons are the particles responsible for nuclear fission in a nuclear reactor.
