Here’s How a Nuclear Reactor Actually Works - Nuclear
But how do nuclear reactors work exactly? Our largest source of clean energy uses a process you can’t see: fission. At nuclear power plants across the country, highly trained workers monitor an ongoing chain reaction that generates heat and steam, which is then converted to electricity using a turbine.
