Nuclear fusion is when two lighter nuclei fuses to form heavier nuclei, for example two hydrogen atoms fuse to form helium atom. Nuclear fusion can be energy releasing or absorbing. This reaction requires very high temperatures.

Nuclear fission is when a heavy unstable nuclei undergo disintegration and forms to lighter nuclei. It's an energy releasing process.
