13.7 Nuclear Fusion

Fusion: The Combining of Nucleons

The mass per nucleon graph is used to illustrate the mass-energy transformations involved in both nuclear fusion and fission. Duration: 3:21.

Thermonuclear Fusion

In order for nuclei to fuse together they must be hurled towards one another at great speeds in order of overcome the repulsive electric forces between them. This occurs in stars where nuclear fusion is sustained by the generation of much heat. Duration: 5:33.

Fusion for Peaceful Purposes

Controlled thermonuclear fusion can be used for generating electricity without the formation of as many radioactive wastes as arise from nuclear fission power plants. Other benefits are also possible. There are some major technological hurdles, however, that still need to be overcome. Duration: 3:33.
