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.

Why is Nuclear fusion better than Nuclear fission?
At the moment it's not because nobody has been able to get it to work for the sort of duration necessary for power production. There are, however a couple of nice advantages over fusion: - No radioactive waste products (the product is helium-4) - No radioactive raw material (need heavy hydrogen) - Theoretically large energy gain per reaction On the down side it is technically very challenging, requiring extremely high pressure. Getting the inital reaction to start requires a lot of energy.
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 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 process generates the heat and energy in present day nuclear power plants?
Nuclear fission is the process that generates heat and energy in present-day nuclear power plants. In this process, the nucleus of an atom is split into smaller nuclei, releasing a large amount of energy in the form of heat. This heat is then used to generate steam, which drives turbines connected to electricity generators.
What are the benefits of fusion over fission bombs?
higher yield
Why is fusion preferred over fission?
Fusion is preferred over fission because it produces more energy with less radioactive waste and is less prone to accidents. Fusion reactions use isotopes of hydrogen, which are abundant and non-radioactive, as fuel. Additionally, fusion does not produce long-lived radioactive waste like fission reactions do.

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.

What produces more energy fusion or fission?
Yes and No. This really depends on what you mean.If you are talking about a single event, the fission of a uranium atom typically releases about 200 million electron volts (MeV). By contrast, the fusion of a deuterium atom with a tritium atom produces about 17.6 MeV. This would seem to mean that fission produces more energy. And it does - per event.On the other hand, a deuterium atom has an atomic mass of 2, and a tritium atom has an atomic mass of 3. So the fusion involving an atomic mass of 5 produces 17.6 MeV. If we had 47 of these, the total mass would be about 235 (roughly the same as 235U) and the result would be 47x17.6 or 827.2. By contrast, 235U has an atomic mass of roughly 235. And the fission involving the atomic mass of 235 produces 200 MeV. This means that the fusion of an equal mass produces (in this particular comparison) a bit more than four times as much power. So fusion can be more powerful - by mass.But fusion of elements more massive than iron is endothermic. So it is always less powerful than fission.Also, there is a practical consideration, if you are interested in practicalities. And this relates to the amount of fuel available. We will run out of uranium and thorium ores. When that happens, fission power will no longer be possible. We will possibly never run out of fuel for fusion fuels. So fusion is a more powerful power source over time. But of course, by this standard, wind is more powerful than fission, because we will run out of the ores, but the wind will just blow on and on.
