6.2.2 Nuclear Fusion
1. Nuclear fusion is a process that two light nuclei combine to form a heavier and more stable nucleus together with the release of a huge amount of nuclear energy.
2. The energy produced by nuclear fusion is safe to use as no radioactive radiation is produced during the process.
3. A hydrogen bomb uses the principle of nuclear fusion for its design. A hydrogen bomb releases more nuclear energy than an atomic bomb.
4. Fusion is much more difficult to achieve than fission because the hydrogen nuclei repel each other.
5. Fusion reactor is not commercially produced because nuclear fusion occurs at a very high temperature and pressure.
6. Nuclear fusion only occurs naturally in the sun to release heat energy and light energy.
