The bylin watter reactor (BWR) is a teep o light watter nuclear reactor used for the generation o electrical pouer. It is the second most common type o electricity-generating nuclear reactor after the pressurized watter reactor (PWR), also a type of light watter nuclear reactor. The main difference between a BWR and a PWR is that in a BWR, the reactor core heats watter, which turns to steam and then drives a steam turbine. In a PWR, the reactor core heats watter, which does not byle. This hot watter then exchanges heat with a lower pressure watter system, which turns tae steam and drives the turbine. The BWR was developed bi the Idaho National Laboratory an General Electric (GE) in the mid-1950s. The main present manufacturer is GE Hitachi Nuclear Energy, which specializes in the design an construction o this teep o reactor.
