Explaining The Universe on Instagram: "A nuclear reactor is a device that generates energy by controlling a sustained nuclear chain reaction. Inside the reactor core, fuel rods filled with uranium or plutonium undergo fission, where atomic nuclei split apart, releasing heat and neutrons. The heat is transferred to a coolant, often water, which is then used to produce steam that drives turbines to generate electricity. • #explore #reels #viral #universe #explaining #space"
