1. a cooling system for urgent cooling tank, comprising:

  • Be configured to store therein the urgent cooling tank of chilled water, when described chilled water has an accident in nuclear reactor, accept from the heat of nuclear reactor or container transmission;

    Heat exchanger, its be installed into be exposed to urgent cooling tank outside to operate in air, thereby even and if be configured to outside heat release, make also to make the operation of urgent cooling tank to continue by the fluid in urgent cooling tank and the heat interchange between air in the situation that again not filling in chilled water;

    AndBe arranged on urgent cooling tank top so that its position higher than the open and close unit of the water level of chilled water, and the flowing of fluid that described open and close unit is configured to produce by cooling evaporation of water opened, describedly flow to be what the pressure differential due to the extraneous air from than under the higher pressure of preset pressure formed, when transmission exceeds the heat load of cooling power of urgent cooling tank, outwards to emit thus a part for described fluid.
