The Steam Vent and Drain system is a subsystem within the Power Conversion Group (PCG). The Steam Vent system conveys steam and noncondensible gases to the atmosphere or appropriate terminal point as determined by the thermal cycle. Typical steam vent systems are: low pressure heater shell relief valve piping to the atmosphere; and low pressure heater shell vent piping which conducts noncondensible gases to the condenser. The Drain system conveys high temperature water to the condenser to maintain the inventory of secondary fluid during startup.
