Sliding Pressure Startup System of the Super LWR

The sliding pressure startup systems of the Super LWR and a supercritical FPP are shown in Fig. 1.17 [41]. A steam-water separator is installed on the bypass line for the Super LWR, while it is installed on the main steam line for the supercritical FPP. The Super LWR has an additional heater installed to recover heat from the drain of the steam-water separator. When the enthalpy is low, the drain is dumped into the condenser directly. A boiler circulation pump can be used instead of the additional heater the same as in the sliding pressure FPP.
