How a Nuclear Reactor Works

How a Nuclear Reactor Works

The nuclear reactors currently operating in the United States are either boiling water reactors or pressurized water reactors. The names can be a bit misleading: Both use steam to power a generator, but the difference is how they create it. A boiling water reactor heats up the water in the reactor until it boils into steam and spins the turbine.

Nuclear reactor - Coolant system | Britannica

Nuclear reactor - Nuclear reactor - Coolant system: The function of a power reactor installation is to extract as much heat of nuclear fission as possible and convert it to useful power, generally electricity. The coolant system plays a pivotal role in performing this function. A coolant fluid enters the core at low temperature and exits at a higher temperature after collecting the fission energy.
