Nuclear fission is the process of splitting a large atom into two smaller atoms and releasing a LOT of heat. That heat is used to boil water, make steam, turn a turbine and generator, and produce electricity. Most nuclear power plants today are fueled by enriched uranium 235 to produce non-renewable, carbon-free, 24/7 electricity. How Does A Nuclear Submarine Reactor Work. Nuclear submarine reactors work by using nuclear fission to produce heat. This heat is then used to generate steam, which powers the submarine’s turbines. The reactors are typically located at the back of the submarine, and the steam is piped through the submarine to the turbines.
For now, just understand that the main job of a nuclear reactor isn’t to start the fission reaction; that’s so simple you could do it in your living room.
