Nuclear Energy Concepts and Challenges

The video explains how nuclear energy contributes to 20% of the US's power. It covers the basics of atomic structure, the process of nuclear fission using uranium, and how nuclear reactors work. The video also discusses the pros and cons of nuclear power, including its environmental impact and safety concerns. Additionally, it touches on other uses of nuclear energy, such as in stars like the Sun.
