the first safety facility execution device, the second safety facility execution device and the third safety facility execution device are respectively and independently connected with the process control center, and the process control center is connected with the post-accident monitoring system.
In a nuclear power plant, the treatment and maintenance of a reactor are particularly important, if the reactor is not maintained properly, polluting substances are easy to leak out, huge potential safety hazards are caused to the nuclear power plant and the surrounding environment, and the requirement on the safety level in the nuclear power plant is high.
The process control cabinet system comprises: the first detection device, the second detection device, the third detection device and the fourth detection device, wherein the process control cabinet system comprises 4 redundant and independent detection devices. When one or two or three of the first detection device, the second detection device, the third detection device and the fourth detection device has faults, other detection devices can still normally operate to detect the reactor in real time.
Two or three or four of the first detection device, the second detection device, the third detection device and the fourth detection device can be operated simultaneously, so that the detection accuracy of the reactor detection system is improved.
The process control cabinet system comprises: the first safety facility execution device, the second safety facility execution device and the third safety facility execution device comprise 3-fold redundant and independent safety facility execution devices in the process control cabinet system. When one or two of the first safety facility execution device, the second safety facility execution device and the third safety facility execution device fails, other safety facility execution devices can still normally operate, and the safety of the reactor is guaranteed.
Two or three of the first secure facility execution device, the second secure facility execution device and the third secure facility execution device may operate simultaneously, improving reliability of the secure facility execution system.
The redundancy and the reliability of the process control cabinet system are improved by arranging 4 redundant and independent detection devices and 3 redundant and independent safety facility execution devices.

In the embodiment of the present invention, a detection manner of the reactor detection system is not limited, for example, the reactor detection system may detect the reactor by using a sensor, and the reactor detection system may also detect the reactor by using other manners, which is not limited in the embodiment of the present invention.
In the embodiment of the invention, the reactor detection system can detect a temperature signal, a liquid level signal, a liquid concentration signal, a pressure intensity signal, a fluid flow rate signal, a device vibration frequency and amplitude signal and the like in the reactor. The reactor detection system detects the reactor and transmits a detection signal to the process control center.
And when the reactor detection system detects a risk signal in the reactor, the reactor detection system transmits the risk signal to the process control center to perform early warning. Then, the process control center starts the safety facility execution system, executes safety measures on the reactor and eliminates the risk signals in the reactor to the maximum extent. After the safety facility execution system executes the safety facility, the post-accident monitoring system performs subsequent monitoring work on the reactor to ensure that the safety facility execution system is executed in place and to ensure that risk signals in the reactor are eliminated.
For example, when the reactor detection system detects that the temperature in the reactor is higher than a preset value by using the temperature sensor, the process control center starts the safety facility execution system, performs a water injection operation on the reactor, reduces the temperature in the reactor, controls the temperature in the reactor within a preset value range, eliminates a temperature risk signal in the reactor, and then the post-accident monitoring system monitors the temperature in the reactor to ensure that the temperature in the reactor is maintained within the preset value range, thereby ensuring the safety of the reactor. It should be noted that the reactor is filled with water, but the safety facility execution system is only one of the ways of controlling the temperature in the reactor, and the safety facility execution system may also eliminate the temperature risk signal in the reactor by other ways.
For another example, when the reactor detection system detects that hazardous substances such as radioactivity and the like in the reactor leak out by using the sensor, the process control center starts the safety facility execution system to perform isolation operation on related equipment, so that the hazardous substances such as radioactivity and the like are effectively prevented from leaking out, and the environment is protected. The post-accident monitoring system may then monitor external channels in the reactor, such as sewers and the like, to ensure that hazardous materials such as radioactivity are not at risk of escaping.
The safety functions of the process control cabinet system include: the reactor shutdown, emergency special safety facility drive and other safety related functions are as follows: safety injection, main water supply isolation, main steam isolation, containment isolation, auxiliary water supply pump starting, emergency diesel engine starting and loading, steam turbine stopping, waste heat discharging, boric acid concentration adjustment, equipment cooling water pumps, important plant water pumps, low-temperature overpressure protection, post-accident monitoring and the like.
