Nuclear Energy Concepts and Challenges

The video explores nuclear energy, explaining its process, advantages, and challenges. It discusses nuclear fission, where uranium and plutonium are used to generate energy. The benefits include high energy density and clean energy, while challenges involve nuclear waste and public perception. Singapore is considering nuclear energy for future use, potentially meeting 10% of its energy needs by 2050.

What is nuclear energy primarily stored within?
