Quick Summary
A natural-circulation reactor is a type of nuclear reactor that uses differences in temperature to circulate water naturally, rather than relying on pumps. Cooled water enters the bottom of the reactor and rises through the fuel elements as it heats up due to nuclear fission. This heated water then transfers its energy to a secondary circuit, producing steam that drives a turbine to generate electricity. This design offers a simpler heat-removal system compared to reactors that use pumps for coolant circulation.12
