Reactor and split tank type voltage stabilizer

Abstract

The invention relates to a reactor and a split tank type voltage stabilizer. The split tank type voltage stabilizer comprises at least two voltage stabilization tanks arranged side by side, a steam pipeline and a water flow pipeline, wherein each voltage stabilization tank internally comprises a steam space positioned at the upper part and a saturated water space positioned at the lower part; thesteam pipeline is respectively communicated with the steam space of each voltage stabilization tank so as to balance a pressure of the steam space of each voltage stabilization tank; the water flow pipeline is respectively communicated with each saturated water space so that the saturated water space of each voltage stabilization tank is communicated into a big saturated water space. In an ocean shaking environment, a shaking degree of a liquid level of each voltage stabilization tank is much smaller; the split tank type voltage stabilizer can be flexibly and compactly arranged and occupies avery small effective space of a reaction chamber, resulting in that a size of the reaction chamber can be made smaller; in the operating process, if a certain voltage stabilization tank has a fault, the residual voltage stabilization tank can continuously operate for a period, so that the fault survival ability of the reactor is higher; no fluctuation chamber is formed inside the split tank type voltage stabilizer, so that the split tank type voltage stabilizer is simpler in structure and easier in equipment manufacturing.

Description

technical field [0001] The invention relates to the field of nuclear power, more specifically, to a reactor and a sub-tank voltage stabilizer. Background technique [0002] Steam pressurizers are commonly used in pressurized water reactor nuclear power plants. They are usually vertical cylindrical pressure vessels with upper and lower hemispherical heads. Valves and other components. The interior of the pressurizer is divided into an upper steam space and a lower water space, and the working fluids are saturated steam and saturated water respectively, which are in a two-phase equilibrium state. Among them, the pressure of the vapor space of the pressurizer is used to characterize the operating pressure of the reactor coolant system. [0003] The pressurizer is an important device to control the pressure change of the reactor coolant system. It has the functions of pressure regulation and pressure protection under the reactor start-up, shutdown, steady-state operation, nor...

Problems solved by technology

[0006] The inside of the voltage stabilizer is divided into the upper air space and the lower saturated water space. In the ocean sloshing environment, the liquid level in the large-diameter cylinder sloshes very seriously, which will lead to large deviations in liquid level monitoring, and even often trigger the stack jump signal by mistake. detrimental to the normal operation of the reactor
