This steam is then condensed and recycled back to the reactor core. A schematic of a BWR is shown in Figure 17.1.

A boiling water reactor (BWR) is a type of light water nuclear reactor used for the generation of electrical power. It is a design different from a Soviet graphite-moderated RBMK. It is the second most common type of electricity-generating nuclear reactor after the pressurized water reactor (PWR), which is … See more A boiling water reactor uses demineralized water as a coolant and neutron moderator. Heat is produced by nuclear fission in the reactor core, and this causes the cooling water to boil, producing steam. The steam is directly used to … See more Early concepts The BWR concept was developed slightly later than the PWR concept. Development of the BWR started in the early 1950s, and was a collaboration … See more Start-up ("going critical") Reactor start up (criticality) is achieved by withdrawing control rods from the core to raise core reactivity to a level where it is evident that the See more • Boiling water reactor safety systems • BORAX experiments • Climate change mitigation See more Condensate and feedwater Steam exiting the turbine flows into condensers located underneath the low-pressure turbines, … See more Advantages of BWR • The reactor vessel and associated components operate at a substantially lower pressure of about 70–75 bars (1,020–1,090 psi) … See more For a list of operational and decommissioned BWRs, see List of BWRs.
