A boiling water reactor (BWR) is a type of light (H₂O and not HDO or D₂O in which hydrogen has been replaced by deuterium) water nuclear reactor used for the generation of electrical power.

The steam in boiling water reactor is produced directly in the reactor core, while, in contact, the steam in a pressurized water reactor (PWR) is produced in a secondary system. The pressure of a pressurized boiling reactor varies from the primary system to the output steam, while the pressure of a boiling water reactor remains constant.

An advantage of the pressurized water reactor is that the pressurized water reactor can operate at higher temperature and pressure on the order of approximately 315°C (600°F) and 2,400 psi. This provides a higher efficiency than the boiling water reactor.
