The video explains how nuclear reactors work by splitting large atoms like uranium in a process called nuclear fission. This process releases energy due to mass-energy conversion as described by Einstein's equation E=MC^2. A chain reaction occurs when neutrons released from splitting atoms cause further splits. Control rods are used to manage this reaction to prevent nuclear meltdowns and regulate power output. The video also discusses the importance of safety in nuclear energy production and the potential to reduce fossil fuel use.
