So, have you ever seen a tea kettle whistle when the water inside gets boiling hot? Well, a steam generator in a nuclear power plant is kinda like a giant tea kettle.
You see, in a nuclear power plant, they use special uranium rods to make heat. This heat is used to turn something called a turbine, which helps make electricity.
But wait - we need something to help the heat turn the turbine, right? That's where the steam generator comes in!
The steam generator takes water and heats it up using the heat from the uranium rods. This turns the water into steam (just like how tea kettle turns water into steam).
The steam then goes through pipes to the turbine, which gets turned by the steam and helps make electricity. And that's how a steam generator helps make electricity in a nuclear power plant!
