Fission |
Fusion |
1.
|
When heavy and unstable nuclear is bombarded with neutrons,
the nucleus splits into fragments of equal mass and energy is released.
|
Some light element fuse together with release of energy is
known as fusion.
|
2.
|
Nuclear reaction residual problem is great.
|
In fusion residual problem is much less.
|
3.
|
Fission involve more amount of radioactive material in
fission reactor.
|
Fusion has a possible advantage is that the total amount
of radioactive material in a working fusion reactor is likely be very much
less that that in a fission reactor.
|
4.
|
It has higher risk of health hazarded in case of accident.
|
Because of lesser radioactive material than fission, health
hazards are much less.
|
5.
|
About one thousandth of the mass is converted into energy.
|
It is possible to have four thousandths of mass converted
into energy.
|
6.
|
It is possible to construct self sustained fission reactors
and have positive energy released.
|
It is extremely difficult to construct controlled fusion
reactors.
|
7.
|
Fission can obtain manageable temperature.
|
It involves unmanageable temperature like 30 million degrees
for fusion process.
|
8.
|
Raw fissionable material is not available in plenty.
|
Reserves of deuterium, the fusion element, are available in
great quantity.
