6.2.1 Nuclear Reactions

Why nuclear energy by nuclear fusion reaction is not able to produce?

• Need highly extreme temperature and pressure

• Need high temperature

• Require large nuclear reactor

• High cost of production

How is nuclear fusion different from nuclear fission?

• In fission, the product is a larger atomic nucleus.

• Fission produces energy but fusion does not.

• Fusion produces energy but fission does not.

• In fusion, the product is a larger atomic nucleus.
