How a Pressurized Water Nuclear Reactor Works (Part I)
Pressurized water nuclear reactors like the ones at Prairie Island use a three-loop water system to produce electricity and nuclear waste.
Heat in the reactor core comes from a chain-reaction of exploding uranium atoms. In the core, primary water is heated above 600 degrees Fahrenheit.
Hot primary water is pumped through steam generators,
where heat is transferred to secondary water that flashes into steam.
Primary water returns to the core for reheating.

Very high pressure
keeps primary
water from boiling.
