is the combination of a boiler and a heat exchanger section (the superheater), where steam is superheated.

is a large, vertical, inverted-U-tube-and-shell heat exchanger with hot reactor coolant on its tube side transferring heat to and boiling the non-nuclear feedwater to form steam on the shell side.  Besides transferring heat, the steam generator is important as a barrier between the nuclear and non-nuclear coolants.
