Attachment to GNRO-2012/00093 Page 15 of 15 Section 2.3.4.2 Condensate Cleanup The purpose of the condensate cleanup system (system code N22) is to maintain the required purity of feedwater flowing to the reactor. Normally, demineralizers are in operation processing full condensate flow. The condensate cleanup system consists of eight units of deep-bed-type demineralizers (with two units as spares) that operate in parallel, and thFss pFsooat filtsFs (with ons unit as spam) a condensate full flow filtration system used for startup. The system also includes the associated piping, ultrasonic resin cleaner, the advanced resin cleaning subsystem, and all necessary valves, instrumentation and controls.
