Dry Saturated Steam - an overview ScienceDirect

A BWR produces saturated steam at 65 bar. The steam expands to the condenser pressure of 0.06 bar through a high-pressure turbine to 5 bar, followed by an external moisture separator which produces dry steam again, then the low-pressure turbine. Both turbines have a degree of internal moisture separation.
