Pressurized Water Reactor (PWR):Pumps for nuclear …

This pump takes from the deaerator storage tank feed water pressured up by the booster pump and pushes it into the steam generator through the high-pressure heater. Accordingly, the main feed pump must be high temperature and high-pressure pump since it requires the head larger than the pressure inside the steam generator.

How do power plants work? How do we make …

A power plant's job is to release this chemical energy as heat, use the heat to drive a spinning machine called a turbine, and then use the turbine to power a generator (electricity making machine). Power plants can make so much energy because they burn huge amounts of fuel—and every single bit of that fuel is packed full of power.
