Answer:

Therefore, The chain reaction used in nuclear power plants involves a free

neutron colliding with a uranium , forming more free neutrons and energy .

Step-by-step explanation:

A chain reaction refers to a process in which neutrons released in fission produce an additional fission in at least one further nucleus. This nucleus in turn produces neutrons, and the process repeats.

For example, 21/2 neutrons on the average are released by the fission of each uranium-235 nucleus that absorbs a low-energy neutron provide more neutrons and energy.
