First a Disclaimer I'm not a physicist or a nuclear engineer. I'm just a guy who has read a few books and listened to a few podcasts by nuclear engineers about this topic. I don't know everything about nuclear power plants, but I think I have an understanding of the basics. So with that said, here's the basic outline of how a reactor core is shut down: Image: Wikipedia , CC Nuclear Reactors 101 The first thing to understand is that the core is where the nuclear reaction that produces enough heat to boil water and spin turbines takes place. Fuel rods made of enriched radioactive materials, usually uranium containing around 20% of the more unstable U235 (a nuclear bomb contains materials that are enriched to 90%+, which is why it's physically impossible for a nuclear power plant to explode like a nuclear weapon), are bombarded with neutrons. Some of these neutrons will hit t...
