PWR = pressurised water reactor. BWR = boiling water reactor
I think you are talking about nuclear reactors. PWR is a Pressurized Water Reactor, and is the basis for most power generators. BWR is a Boiling Water Reactor. As the water is a major moderating component, controlling the speed and intensity of the nuclear reaction, the steam bubbles in a BWR can present a problem.
BWR Public Relations offers several different types of services. Some of these include: Corporate Communications, Brand Marketing, and Events and Social Advocacy.

Reactors of the BWR and PWR types
PWR and BWR reactor types. Look up in Wikipedia.
BWR = Boiling Water Reactor. In this type a certain proportion of the reactor coolant water is allowed to turn to steam (unlike in a PWR), this steam is separated out from the water after the reactor outlet and passes directly to the steam turbine.
Nuclear power plants (BWR, PWR, AGR, etc.)
They don't. BWR's run wet saturated steam. There is no superheating in a BWR, because there is no way steam would come in contact with a heat source. The plant must be built to be compatible with wet steam that could condense.
All power producing reactors are either PWR or BWR types
