Nuclear power plant voltage stabilizer for inhibiting liquid level sloshing

Abstract

The invention discloses a nuclear power plant voltage stabilizer for inhibiting liquid level sloshing. The voltage stabilizer comprises a voltage stabilizer main body, the upper portion of the voltage stabilizer main body serves as a gas storage space, the lower portion of the voltage stabilizer main body serves as a liquid storage space, a plurality of spacing boards for preventing liquid sloshing are arranged in the voltage stabilizer main body, and the spacing boards are arranged at intervals. The voltage stabilizer is suitable for being used in a marine environment, has a good sloshing inhibiting effect and effectively enhances the environmental adaptive capacity of a nuclear power plant.

Description

technical field [0001] The present invention relates to a voltage stabilizer, in particular to a voltage stabilizer for nuclear reactors under marine conditions. Background technique [0002] The voltage stabilizer is used in the primary circuit of the nuclear reactor. When an accident occurs in the primary circuit and the pressure increases or decreases, the pressure of the primary circuit is automatically adjusted to ensure the normal operation of the primary circuit. There are generally two types of existing pressurizers, one is a steam pressurizer, and the other is a nitrogen pressurizer. [0003] like figure 1 As shown, the steam pressurizer 300 is a vertical cylindrical container with hemispherical upper and lower heads 301, 302, in which the liquid and steam are maintained in a balanced saturated state. The specific structure is that the lower part of the steam regulator 300 is a water space 303, which has a wave nozzle, an electric heater and an instrument nozzle; ...

AI Technical Summary

Problems solved by technology

[0006] 1. This kind of fluctuation will cause a great stress impact on the inner wall of the voltage stabilizer, which may damage its structural integrity

[0007] 2. The sloshing of the free liquid surface in the regulator may cause the electric heater or heating tube at the bottom of the vapor regulator to be exposed, causing the electric heater to burn out, and may also flood the sprayer on the top of the regulator, reducing the stability The effect of the spray pressure reduction of the pressure regulator sprinkler

[0008] 3. The sloshing of the free liquid surface in the regulator will affect the accuracy of the sensor for measuring the water level inside the regulator, increasing the difficulty of measuring the liquid level of the regulator

[0009] 4. The existence of the free liquid surface of the voltage stabilizer makes it have higher requirements on the application environment, thus reducing the environmental adaptability of the nuclear power plant
