Nuclear Fusion and Fission Concepts

The video tutorial explains nuclear fission, a process occurring in nuclear power plants and atomic bombs, where uranium-235 is split by neutrons, releasing energy and more neutrons, potentially causing a chain reaction. In power plants, this reaction is controlled using heavy water to slow neutrons. The video also covers nuclear fusion, where small atoms like hydrogen isotopes combine at high temperatures to form helium, a process similar to what occurs in the sun.

What is nuclear fission?

• The formation of new isotopes

• The release of energy from chemical reactions

• The splitting of an atom's nucleus

• The process of combining two atoms

What isotope of uranium is commonly used in nuclear fission?
