fusion reaction is brought about by means of very high temperature, and they are thus
referred to as 'thermo-nuclear processes'.

12.1.4 Chain Reaction

A chain reaction or nuclear chain
reaction is a sequence of reactions.
A reactive product or by-products
from the first reaction followed by
additional reactions to take place. In
a chain reaction, positive feedback
leads to a self-amplifying chain of
events. In nuclear chain reaction a
high speed neutron is used to
bombard the nucleus of the fissile
atom. This breaks the nucleus into Fig. 12.3
smaller atoms and in the process also releases additional high-speed neutrons. These
high-speed neutrons bombard with the other atoms of fissile material. This process
continues to form a nuclear chain reaction. The uncontrolled nuclear chain reaction
leads to the release of large amount of heat energy, which causes destruction.
