The bylin watter reactor (BWR) is a teep o light watter nuclear reactor used for the generation o electrical pouer. It is the saicont maist common teep o electricity-generating nuclear reactor efter the pressurized watter reactor (PWR); it is forby a teep o light watter nuclear reactor. The main differ atween a BWR an a PWR is that in a BWR, the reactor core heats watter, whilk turns intae staem an syne drives a steam turbine. In a PWR, the reactor core heats watter, whilk disnae byle. This het watter syne exchanges heat wi a laicher pressure watter seestem, whilk turns intae staem an drives the turbine. The BWR wis developpit bi the Idaho National Laboratory an General Electric (GE) in the mid-1950s. The main manufacturer thir days is GE Hitachi Nuclear Energy, whilk specializes in the design an construction o this teep o reactor.
