Embodiment Construction
[0022] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0023] Such as figure 1 Shown is the passive containment cooling system provided by the present invention. The system includes a top water tank 5 fixed outside the containment and a spiral coil water wall 1 arranged in the containment. One end of the spiral coil water wall 1 passes The natural circulation inlet pipeline 3 is connected with the overhead water tank 5, and the other end of the spiral coil water wall is connected with the overhead water tank 5 through the natural circulation outlet pipeline 2.
[0024] The spiral water-cooled wall 1 is arranged in the area of the containment dome 4, and its outer contour surface fits the containment dome 4, and is connected to the containment dome 4 through a longitudinal rigid fixing member 6 and a horizontal elastic fixing member 7 respectively.
[0025] The spiral coil water wall 1 inclu...
