Reactor feedwater pump
WebIn the Main Feedwater System, three of the pumps are steam turbine driven. The fourth pump is motor driven and is normally only used for startup and shutdown. This pump starts automatically on loss of main feedwater and reactor trip (see CESSAR-DC, Section 10.4.7.2.3.D). [Pg.186] WebInternal treatment protects against feed water hardness by preventing precipitating of scale on the boiler tubes. This treatment also protects against concentrations of dissolved and suspended solids in the feed water without priming or foaming.
