How Nuclear Fission Leads to an Atomic Explosion! When a Uranium-235 nucleus absorbs a thermal neutron, it splits into fission fragments, releasing ~200 MeV energy and 3 fast neutrons. These neutrons trigger a chain reaction, which—if uncontrolled—results in a massive nuclear explosion, like an atomic bomb. But when controlled, the same process powers nuclear reactors! #NuclearFission #AtomicBomb #PhysicsExplained #ScienceFacts #ChainReaction #NuclearEnergy #PhysicsLover #Engineering #EnergyProd
