Beschreibung
Zusammenfassung:	The invention particularly relates to a main water supply automatic control system for a sodium-cooled fast reactor under low power, and the system comprises a PID controller A which is used for controlling the opening degree of a main water supply bypass regulating valve of a steam generator of the sodium-cooled fast reactor during water-steam conversion or steam-water conversion sequence control of the sodium-cooled fast reactor; the PID controller B is used for controlling the valve opening degree of an inlet regulating valve of a sodium-cooled fast reactor starting flash tank during water-steam conversion or steam-water conversion sequence control of the sodium-cooled fast reactor; the PID controller C is used for controlling the valve opening degree of the main water supply bypass regulating valve of the sodium-cooled fast reactor steam generator when the sodium-cooled fast reactor is shut down emergently or the power is increased and decreased; and the PID controller A, the PID controller B and the PID
