Problems solved by technology

[0003] However, when the nuclear power plant is placed on the floating platform, external conditions such as waves, wind, ocean currents, and the movement of the floating platform will cause the nuclear power plant to tilt, undulate, and sway. At this time, the free liquid surface in the depression pool Strong nonlinear sloshing phenomenon may occur
When sloshing occurs in the suppression pool, the inner wall of the suppression pool will be subjected to different degrees of impact pressure generated by the sloshing, which will endanger the structural integrity of the suppression pool, reduce the reliability of the suppression pool system, or cause the function of the suppression pool to be damaged. loss of
Therefore, in the boiling water reactor technology, the suppression pool system cannot effectively suppress the possible sloshing phenomenon, and cannot be directly applied to platforms at sea or under moving conditions
In addition, the existing two-stage containment containment technology adopts a two-stage containment method. When a high-energy pipeline breaks in the containment, although it can effectively reduce the pressure in the containment, the structure of this method is complicated and it is not suitable for Applied to compact nuclear power plants

Abstract

The invention discloses a suppression pool. The suppression pool is mounted in a shell body of a safety shell and is annularly arranged around a reactor pit of the shell body. The suppression pool comprises a water space and an air space, wherein a plurality of anti-shaking partition boards are arranged in the water space; and communication holes for communicating two sides of the anti-shaking partition boards are formed in the bottoms of the anti-shaking partition boards. According to the suppression pool, the shaking of the liquid level can be prevented. The suppression pool is simple in structure and convenient to maintain. The invention further discloses the safety shell with the suppression pool.

Description

technical field [0001] The invention relates to a containment vessel, in particular to a containment vessel with a depressurized water pool for preventing sloshing of the liquid surface and used for a floating nuclear power plant at sea. Background technique [0002] The decompression pool is installed in the containment and arranged in a ring around the pressure vessel. It can be divided into air space and water space. It communicates with the atmosphere of the containment through the exhaust channel. Due to the pressure difference, the mixture of air and air enters the suppression pool through the exhaust channel to be cooled, thereby inhibiting the increase in the pressure of the containment vessel. [0003] However, when the nuclear power plant is placed on the floating platform, external conditions such as waves, wind, ocean currents, and the movement of the floating platform will cause the nuclear power plant to tilt, undulate, and sway. At this time, the free liquid s...
