GCSE Physics - Nuclear Fission #38

The video explains nuclear fission, where large unstable nuclei split into smaller ones, releasing energy. Fission can occur spontaneously or be induced by neutrons, with the latter used in reactors. The process involves firing a neutron at uranium 235, causing it to split and release energy and more neutrons, leading to a chain reaction. This reaction must be controlled in reactors to prevent disasters. The video also discusses the pros and cons of nuclear energy, highlighting its cost-effectiveness and clean energy production, but also the risks and waste management challenges.

Describe the chain reaction that occurs during nuclear fission.

What are the pros and cons of using nuclear energy?
