Explain Nuclear Fusion Reaction.
NUCLEAR FUSION REACTIONS:-
These reactions take
place by combination or fusion of two small nuclei into a larger nucleus. At
extremely high temperatures the kinetic energy of these nuclei overweighs the
electrical repulsions between them. Thus, they coalesce to give an unstable
mass which decomposes to give a stable large nucleus and small particles as proton
neutron and positron.
1. Lighter nuclei fuse together to form the heavier nucleus.
2. Extremely high
temperature is required for fusion to take place.
3. It is not a chain
reaction.
4. It cannot be controlled and energy released cannot be
used properly.
5. The products of a fusion reaction are nonradioactive in
nature.
6. No nuclear waste
is left at the end of the fusion reaction.
