Question

Nuclear fusion is more reliable and sustainable source of energy than nuclear fission chain reaction justify this statement with plausible arguments

Answer 1

Answer:

1. Nuclear fusion does not generate radioactive nuclear wastes as nuclear fission does.

2. Nuclear fusion cannot lead to disastrous powerplant explosions as nuclear fission does.

3. More energy is generated during nuclear fusion than in nuclear fission.

Explanation:

Nuclear fusion involves the combination of lighter atoms such as hydrogen to form a heavier nucleus, in the process producing a tremendous amount of energy.

Nuclear fission on the other hand involves splitting a heavy nucleus into two lighter nuclei, releasing energy in the process.

• Nuclear fusion can be more reliable than nuclear fission in energy generation due to the following reasons:
• There are no radioactive waste products obtained as a result of nuclear fusion, unlike nuclear fission. This is because the elements involved in Nuclear fusion are relatively radioactively stable elements.
• The risk of nuclear powerplant explosion due to out of control chain reactions is reduced in nuclear fusion because the reaction can only occur in perfect conditions under high pressure and temperatures (e.g the sun). When any of these conditions is removed due to a fault, the reaction automatically stops.
• More energy is generated during nuclear fusion than in nuclear fission.

Answer 2

Nuclear fusion and fission release a tremendous amount of energy using radioactive material as a fuel.

What are Fusion and fission?

Nuclear fusion is a reaction that occurs when two nuclei merge to form a larger nucleus and release a massive quantity of energy.

The breaking of two nuclei into smaller nuclei is known as nuclear fission. Nuclear fission also releases a significant amount of energy.

The key is how tightly the nucleons in a nucleus are bound together. The surplus energy will be released if a nuclear reaction produces nuclei that are more closely bonded than the originals. The most securely bound atomic nuclei are found to be around the size of iron-56. Thus,

When a nucleus significantly larger than iron is broken into tiny bits, energy is released since the smaller fragments have lower energy.
