WebMar 5, 2024 · Schematic GE BWR inside a Mark I containment. General Electric 's BWR product line of boiling water reactors represents the designs of a relatively large (~18%) [1] percentage of the commercial fission reactors around the world. The progenitor of the BWR line was the 5 MW Vallecitos Boiling Water Reactor (VBWR), brought online in October … 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 nuclear chain reaction is self-sustaining. This is known as "going critical". Control rod … 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, where the steam is cooled and returned to the liquid state (condensate). The condensate is then pumped through See more Advantages of BWR • The reactor vessel and associated components operate at a substantially lower pressure of … See more For a list of operational and decommissioned BWRs, see List of BWRs.
