: Demineralized water flows upward through the core, absorbing this heat and boiling into a steam-water mixture.

A is a type of light-water nuclear reactor where the coolant water is allowed to boil directly within the reactor core. This steam then travels directly to a turbine to generate electricity, making it a "direct-cycle" system. How it Works

: Enriched uranium fuel in the reactor core undergoes nuclear fission, releasing massive amounts of heat.

: Before exiting the reactor vessel, the mixture passes through steam separators and dryers to remove water droplets, ensuring only "dry" steam moves forward.

: This steam travels through pipes directly to a turbine, which spins a generator to create electricity.
