Chapter 11: The Atomic Nucleus
Nuclear fission is a process whereby a nucleus splits in half. Only a select number of radioactive elements are fissionable. The chain reaction and the concept of critical mass are also discussed. Duration: 9:48.
The heat emitted from the nuclear fission of a U-235 enriched sample of uranium is hot enough to boil water. The steam from this water can be used to turn a turbine to generate electricity. The basic design of an electricity producing nuclear power plant is described. Duration: 4:51.
Energy from nuclear fission is beneficial in that it produces few air pollutants. Nuclear fission reactions, however, do generate significant amounts of radioactive wastes. The nature of these radioactive wastes are discussed. Duration: 3:31.
