In order to ensure the safety of the reactor, the amount of water and steam entering a primary loop system of the reactor must be reduced, and the steam generator emergency discharge system discharges the water and the steam in the steam generator into a discharge tank by utilizing the pressure difference and the height difference of a secondary loop, which are higher than the pressure difference and the height difference of the discharge tank, so that the amount of the steam entering a primary loop coolant can be effectively reduced.
