Example Embodiment
[0023] Example 1
[0024] Such as figure 1 As shown, a reactor 6 is provided in the containment 3, and a passive containment cooling and pressure reduction system according to the present invention includes a containment suppression subsystem 4 and a containment cooling subsystem 5.
[0025] The containment suppression subsystem 4 includes a suppression water tank 42 arranged in the containment 3 and a discharge channel 41 passing through the top of the suppression water tank 42. Among them, the suppression water tank 42 is a closed water tank or pool, the upper part of the suppression water tank 42 is the air space, and the lower part is water 43; the discharge channel 41 is a plurality of parallel channels, one end of these channels is connected to the water in the suppression water tank 42 , The other end is connected to the atmosphere in the containment 3.
[0026] The containment cooling subsystem 5 includes an outer shell cooling pool 54 arranged above the outside of the conta...
