The two types of nuclear reaction are the fusion and the fission,
Fission involves the splitting of heavy
nuclides into a two unequal atoms plus neutrons and other particles, the energy
released is less than fusion, it can be harnessed for generation of electricity,
it does not occur naturally, most of its
products are radioactive, high speed neutrons are required, uranium is the
primary fuel.
fusion involves the combining of light
nuclides into a heavy one , it occurs naturally as in the sun and stellar
nucleo-synthesis. most products are stable. , it need high density, temperature
and pressure, need fission energy to start, never harnessed for peaceful use,
fuel are only hydrogen isotopes.
fission nuclear reaction involves the
weakening of the atomic nuclides, causing the overcome coulomb force to wake up
as explained by the liquid drop model. where as in fusion reaction it involve
the overcoming the electrical repulsion
between the nucleus of the participating
atoms.
very high
temperature of about 100 million kelvin and intense pressure are needed to
strap the atom into plasma state and intense pressure capable of overcoming the
coulumb’s repulsion and to squeeze the
atoms into nuclear distance where the strong nuclear force can take effect. in
order word the coulomb barrier must be overcome before fusion can take place.
