The binding energy (Strong Atomic Force) released is much greater when fusion occurs than when fission occurs. As an example, that is why fission bombs typically have yields around 100 to 500 kilotons of equivalent TNT, while fusion bombs typically have yields in the 25 to 50 megaton range. The problem is that fusion requires a lot of energy to initiate - in fact, most fusion bombs use a fission bomb to set them off.

Describe three advantages nuclear fusion would have over nuclear fission.?
1. Unlike fission, during fusion tremendous amount of energy is liberated. Hence fusion of a very small mass generates large amount of energy. 2. Unlike fission the products of fusion reactions are not radio-active. Thus they are harmless and can be replaced easily. 3. Highly penetrating radiations are liberated during fission, which are highly hazardous.

Is the radius of the earth's orbit reduced by the sun's loss of mass through nuclear fission?
No. The loss of mass of the Sun - by the process of nuclear FUSION (not fission) and the conversion of mass into energy is essentially negligible even over the 5-billion-year time scales.
What are the main reasons why nuclear fusion have not been used in nuclear reactors?
Well, scientists have been researching fusion reactors for over 50 years, but nuclear fusion is much more difficult to achieve than nuclear fission, which is what current nuclear power technology is based on. There are many reasons for this, but while there have been tests and advancements in the field, scientists have yet to a) create a sustainable and stable nuclear fusion reaction and b) create a reaction that has a greater output than input.
What processes a molecule splits releasing neutrons and energy?
In nuclear fission it is the nucleus of the atom that splits, not a molecule, and this releases neutrons and energy. Reactions at the molecule level are termed chemical reactions, not nuclear, and these chemical reactions involve whole atoms and molecules.

What process generates the heat and energy in present day nuclear power plants?
Nuclear fission and nuclear fusion are the two processes that are used in the nuclear power plants. Nuclear fission refers to the process of splitting the atomic nuclei while nuclear fusion refers to the process of joining the atomic nuclei.
What advantages would a fusion reactor have over the fission reactors currently being operated?
Plenty of cheap fuel, and no radioactive waste.
Is nelclear energy renewable?
No, nuclear is depleting resource. Nuclear energy exist since beginning of the universe and it degrading from nuclear fusion to larger element and over fuse to larger atoms and became our fission fuel.

What are the benefits of fusion over fission bombs?
higher yield
Why is fusion important?
Because it may hold the key to a sustainable and highly powerful energy source and is capable of being a very powerful nuclear weapon. Scientifically, fusion is important as it is the reason that all the elements were created and is the power source behind the sun and all other stars.
Why did president Eisenhower favor the development in nuclear weapons?
The Soviet Union had exploded its own nuclear bomb (a fission bomb) in 1949, and Truman wanted the United States to stay ahead of the Soviet Union... as did lots of other people. So a fusion bomb (more powerful than a fission bomb, but used a fission reaction to set off a fusion reaction) was developed.
How does the energy released by fusion compare in magnitude with that released by fission?
In a fission reactor which has been operating at a steady power level, on shutdown the fission reactions stop at once, but the radioactivity of the fission products in the fuel still produces thermal energy. This is about 6.5 percent of the previous power level immediately, dropping to about 1 percent after 1 hour. In the case of fusion, there are no fission products so this comparison does not exist, in fact if fusion reactors can ever be made, this is one of the advantages over fission reactors.
