Secondary system

The secondary system receives superheated steam from the NSSS as shown in Figure 15.9. It uses most of the steam for electricity generation, seawater desalination and

the pre-heaters. The main steam pressure is controlled so as to be constant during a power operation. A load change is achieved by changing the feedwater flow rate. A seawater desalination system such as the MED (multiple effect distillation), MSF (multiple stage flash), and RO (reverse osmosis) may be used in conjunction with the secondary system by using proper interfacing methods.
