It should also be understood that the terms used in the embodiments of the present invention are intended to describe specific embodiments, rather than to limit the scope of protection of the present invention. The test methods for which specific conditions are not specified in the following examples are usually carried out under conventional conditions or according to the conditions recommended by the manufacturers.

[0031] See also Figures 1 to 3 . It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size, without affecting the effects and purposes that can be achieved by the present invention, should still fall within the scope of the technical content disclosed by the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0032] When numerical ranges are given in the embodiments, it should be understood that, unless otherwise specified in the present invention, both endpoints of each numerical range and any value between the two endpoints can be selected. Unless otherwise defined, all technical and scientific terms used in the present invention are familiar to those skilled in the art and the description of the present invention, and any methods, equipment and materials of the prior art similar or equivalent to the methods, equipment and materials described in the embodiments of the present invention can also be used to implement the present invention.

[0033] During the improvement process of this case, one of the technical solutions is that the operator in the main control room 100 mainly monitors the nuclear power plant in real time through the digital operator workstation combined with a large screen. At the same time, the following multiple safety-level human-machine interface devices are configured to provide the operator with diversified monitoring means to ensure the stable and safe operation of the unit:

[0034] First, the emergency control panel, which manually triggers the shutdown, turbine tripping, generator tripping or starts the special safety facilities; second, the diversity human-machine interface system panel, which is independent of the manual control, alarm and indication functions of the reactor protection system, is used in the case of common cause failure of the reactor protection system software; third, the severe accident panel, which provides manual control, parameter display, alarm and other functions related to severe accident control and monitoring functions in the case of severe accidents and complete power failure; fourth, the auxiliary control panel, as a backup information display and operating system device of the secondary distributed control system of the nuclear power plant, is used to provide control and monitoring means for the operator when the non-safety-level computer information and control system fails or is planned for maintenance. However, the design scheme of the main control room 100 still has a large number of redundant monitoring means, which is still not suitable for the operating characteristics and requirements of the modular thermal pressurized water reactor, and it is difficult to monitor the operation of two reactor units in the main control room 100 at the same time.

[0035] The modular small heating pressurized water reactor is a non-passive and safe multi-purpose reactor that can be used for power generation, nuclear heating, industrial steam, seawater desalination, etc. It has the advantages of modular design, simple system, and reliable operation. Compared with traditional large-scale million-kilowatt pressurized water reactor nuclear power plants, the modular small heating pressurized water reactor has the advantages of simple system, small number of equipment, and higher inherent safety. The main control room 100 is the most concentrated and important place for human-computer interaction in the heating reactor, and plays a vital role in the stable and safe operation of the unit.

[0036] Generally, the safe operation of a nuclear power plant relies on the strict classification of its internal systems and the corresponding high standards to ensure that the public and the environment are protected from the effects of radioactive substances under any circumstances. The safety level and non-safety level involved in this case are relative. The safety level performs safety functions, such as ensuring that the reactor is safely shut down in normal and emergency situations, removing heat from the core, and limiting the consequences of accidents; the non-safety level does not directly participate in safety functions, but can support the operation of the nuclear power plant, such as auxiliary systems or equipment that is not directly related to safety functions; the safety level has a high level of design and manufacturing specifications and needs to meet specific test requirements such as earthquake resistance, radiation resistance, and aging to ensure that safety functions can still be performed under extreme conditions; while the non-safety level has lower design requirements, mainly considering normal operating conditions, and does not need to withstand operations in extreme accident environments. In addition, the term monitoring involved in this case generally refers to monitoring and control.

[0037] It should be noted that the Figure 2 Among them, 1# indicates the control area corresponding to the No. 1 reactor unit, 2# indicates the control area corresponding to the No. 2 reactor unit, and 9# indicates the display area of ​​the entire heating reactor; A indicates the display screen, which may be a touch screen; and B indicates the large screen.

[0038] See also Figure 1-2 , the present invention provides a main control room of a heating reactor, comprising a first workbench 1, a second workbench 2 and a display unit group 3;

[0039] The first workbench 1 includes two operation monitoring units 11, each of which is configured to monitor the operating parameters and / or working screen of the corresponding reactor unit and control the operation of the corresponding reactor unit; the second workbench 2 is arranged at the rear of the first workbench 1, and is used to monitor the operating parameters and / or working screen of the two reactor units; the display unit group 3 is arranged in front of the first workbench 1, and the display unit group 3 includes at least two first display units 31 and a group of common display units 32 arranged between the two first display units 31; each of the first display units 31 is configured to display the information of the reactor unit monitored by the operation monitoring unit 11 on the same side; the common display unit 32 is configured to display the information common to the two reactor units.

[0040] It should be noted that the display unit group 3, the first workbench 1 and the second workbench 2 are all arranged in sequence along the first direction, the display unit group 3 is arranged in front of the field of vision of the first workbench 1, and the second workbench 2 is arranged behind the first workbench 1, wherein the display unit group 3 can be seen from the positions of the first workbench 1 and the second workbench 2, and the two operation monitoring units 11 of the first workbench 1 can be seen from the position of the second workbench 2. It should be understood that the first workbench 1 and the second workbench 2 generally have multiple computer hosts, display screens, human-machine interfaces and other equipment, wherein the first workbench 1 at least also has various controllers or control buttons. The two operation monitoring units 11 of the first workbench 1 monitor the corresponding operating parameters and / or working pictures of the reactor units one-to-one. The operating parameters are mainly the parameters of the reactor unit when it is working, such as time and / or core temperature and / or coolant pressure and / or steam generator pressure and / or liquid level and / or reactor power, etc.; the working picture can be the monitoring picture of the reactor unit when it is working; the computer of the operation monitoring unit 11 can control the operation of the reactor unit, such as adjusting various operating parameters of the reactor unit so that the reactor unit can operate continuously and stably. The two operation monitoring units 11 monitor the two reactor units respectively. The main control room 100 is also equipped with a communication station 13, which is set between the two operation monitoring units 11, so that the operators of the two operation monitoring units 11 can use the communication station 13 more conveniently. The operation monitoring unit 11 has a human-machine interface for the operator to monitor the operation of the reactor unit and perform non-safety functions. Each operation monitoring unit 11 is generally equipped with at least two second non-safety-level computer devices, which include a second non-safety-level display as the main human-machine interface to perform the operation monitoring and control operation tasks of the reactor unit; the operation monitoring unit 11 is connected to the non-safety-level data network shared by the two reactor units. The normal start-up and shutdown of each reactor unit is completed through the corresponding operation monitoring unit 11, and each operation monitoring unit 11 can monitor all the operating parameters of the corresponding reactor unit and / or the overall operating parameters of the two reactor units.

[0041] The second workbench 2 is also called the duty supervisor's desk. The second workbench 2 includes a third non-safety-level computer, which provides a human-machine interface for operation monitoring for the duty supervisor; the third non-safety-level computer includes a third non-safety-level display, which can display the same screen and content as the display of the operation monitoring unit 11, but can only display, and cannot perform operations. The control function of performing operations is locked. Unless the corresponding authority is obtained, control operations cannot be performed, thereby ensuring that the operator at the first workbench 1 can operate independently and avoid the adverse effects caused by simultaneous control operations of the first workbench 1 and the second workbench 2. The second workbench 2 generally includes eight third non-safety-level displays, four main machines and four sets of mouse and keyboard. The display unit group 3 is mainly used to summarize the overall operating conditions of the heating reactor, support the operator to grasp the overall operation status of the heating reactor unit at any time, and the content displayed by the display unit group 3 can complement the content displayed on the operation monitoring unit 11. Each of the first display units 31 is used to display the information of the reactor unit corresponding to the first display unit 31, including the working parameters and / or working pictures of the corresponding reactor unit; the common display unit 32 is used to display the information shared by the two reactor units, including the overall working parameters and / or overall working pictures of the two reactor units, and the working parameters and / or working pictures of the equipment shared by the two reactor units; the common display unit 32 is generally arranged between the two first display units 31, so as to facilitate the monitoring of the display unit group 3 by the operators at the two operation monitoring units 11. The display unit group 3 includes a total of seven large screens, three of which are one of the first display units 31, used to monitor the No. 1 reactor unit, the other three large screens are another first display unit 31, used to monitor the No. 2 reactor unit, and the large screen in the middle is a common display unit 32, used to display the common system information of the two reactor units, so as to provide the overall status information of the units to all personnel in a public manner; the content of the large screens can be fixed, or the content of the screen can be adjusted according to the needs of the operator.

[0042] In this case, through the arrangement of the first workbench 1, the second workbench 2, and the display unit group 3, only two operators are required at the two operation monitoring units 11 at the first workbench 1 to monitor and control the corresponding No. 1 or No. 2 reactor unit, and each operator can view an operation monitoring unit 11, the first display unit 31, and the common display unit 32 at the same time; and the second workbench 2 can monitor the same screen and content as the non-safety-level display of the operation monitoring unit 11, thereby avoiding operator errors at the first workbench 1. The first display unit 31 of the display unit group 3 can display the operating parameters and working screens of the corresponding reactor unit. For example, one of the first display units 31 is used to display the working status of the No. 1 reactor unit, and the other first display unit 31 is used to display the working status of the No. 2 reactor unit, thereby achieving reasonable allocation of resources. The main control room of the heating reactor provided in this case can realize the monitoring of two reactor units. The first workbench 1 is equipped with two operators; the second workbench 2 is equipped with a shift supervisor and a coordinator. During normal operation, each operator monitors one reactor unit respectively, and the shift supervisor performs global monitoring and management of the two units. Under special working conditions (such as overhaul of a unit), the coordinator is arranged to assist the shift supervisor in supervising the specific unit, thereby realizing global monitoring and management of the two units. As a result, the original four staff members required for each reactor unit are optimized to three staff members and one backup staff member required for two reactor units, and the staff allocation has been fully optimized. In addition, since the corresponding equipment layout of the main control room of the heating reactor has been optimized, the monitoring work has also been well optimized, and the work efficiency of each staff member has been fully improved.

[0043] See also Figure 1-2 As an optional embodiment of the present case, a safety monitoring unit 12 is arranged next to each of the operation monitoring units 11, and the circuit and control of the safety monitoring unit 12 are independently arranged from the operation monitoring unit 11 and / or the second workbench 2 and / or the display unit group 3; each of the safety monitoring units 12 is configured to be able to control the safety operation of the corresponding reactor unit.

[0044] It should be noted that each of the safety monitoring units 12 has a human-machine interface for executing safety functions of the corresponding reactor unit, and can monitor the working parameters and / or working screens related to safety of each reactor unit; by making the circuit and control of the safety monitoring unit 12 independent of the operation monitoring unit 11 and / or the second workbench 2 and / or the display unit group 3, when the operation monitoring unit 11 and / or the second workbench 2 and / or the display unit group 3 are all unable to work normally, the basic safety work can also be maintained through the safety monitoring unit 12; wherein, the safety-level cables of the two safety monitoring units 12 are independent of each other in principle and do not interfere with each other. The safety monitoring unit 12 is used to control the safety operation of the corresponding reactor unit, specifically including monitoring and / or emergency shutdown and / or working parameter display of the heating reactor after an accident. Because under accident conditions, when the two operation monitoring units 11 are unavailable, the safety monitoring unit 12 can be used to perform an emergency shutdown, and then provide safety parameter display for the heating reactor after the accident, so that operators can judge the working status of each reactor unit, wherein the safety parameters mainly refer to important working parameters of each reactor unit, such as core temperature and / or coolant pressure and / or steam generator pressure and / or liquid level and / or reactor power, etc.; at the same time, the safety monitoring unit 12 can also display the control rod position in real time, and the operator can operate the control rod and the intermediate loop pump through the safety monitoring unit 12, realize reactor power control through the control rod, and display relevant important parameters.

[0045] See also Figure 1-2 , as an optional embodiment of the present case, the security monitoring unit 12 includes a first security level computer device, a first non-security level computer device, a security level switch and / or a security level indicator light;

[0046] The first safety-level computer device is configured to be able to perform safety-related monitoring operations on the corresponding reactor unit, and the first non-safety-level computer device is configured to be able to display at least part of the parameters of the corresponding reactor unit and / or display the control rod position and / or control the control rod insertion operation.

[0047] It should be noted that the first safety-level computer device is used to monitor the relatively important working parameters of the reactor unit and perform relatively important safety operations. The safety monitoring operations include monitoring after the accident of the heating reactor and / or display of important safety parameters; the first non-safety-level computer device is used to monitor the working parameters of the reactor unit with a lower safety level and perform operations with a lower safety level; for example, the first non-safety-level computer device is used to display at least part of the parameters corresponding to the reactor unit and / or display the control rod position and / or can control the control rod insertion operation. The safety-level switch can, for example, perform the shutdown operation of the corresponding reactor unit. The safety indicator light can, for example, indicate the working status of the heating reactor and / or the functions of early warning and / or alarm; the safety indicator light can intuitively display the operating status of each system of the nuclear power plant through different colors or flashing modes. Under accident conditions, when the operation monitoring unit 11 is unavailable, the safety monitoring unit 12 can be used to perform an emergency shutdown, and the safety monitoring unit 12 can provide important safety parameter display for the operator to judge the status of each reactor unit. Each safety monitoring unit 12 is configured with at least two first safety-level computer devices, a safety-level switch / button, a safety-level indicator light, and at least one first non-safety-level computer device. The first safety-level computer device includes a first safety-level touch display operation screen, and the first non-safety-level computer device includes a first non-safety-level touch screen. The first non-safety-level touch screen is used to execute control rod insertion control and important parameter display.

[0048] See also Figure 1-2 As an optional embodiment of the present case, the first non-safety-level computer device is configured to replace at least part of the work of the operation monitoring unit 11 and the display unit group 3, which includes part of the information display and part of the parameter control of the reactor unit; it should be understood that the first non-safety-level computer device should give priority to more important work when replacing the operation monitoring unit 11 and the display unit group 3.

[0049] It should be noted that when the operation monitoring unit 11, the display unit group 3, and the second workbench 2 all fail, after obtaining the corresponding authority, the corresponding account can be logged in through the first non-security-level computer device, thereby replacing the important work involved in the operation monitoring unit 11 and the display unit group 3, thereby significantly improving the redundancy of the system, so that even if the main system fails, the backup system can take over immediately, reducing the risk of single point failure and ensuring the continuous and safe operation of the nuclear power plant.

[0050] See also Figure 1-2 As an optional embodiment of the present case, each of the operation monitoring units 11 includes a second non-safety level computer device, and each of the operation monitoring units 11 is configured to be able to perform non-safety function monitoring operations on the corresponding reactor unit;

[0051] The control operation of the non-safety function at least includes the start and stop control operation corresponding to the normal operation of the reactor unit and the monitoring of all parameters of the corresponding heating reactor.

[0052] It should be noted that the second non-safety-level computer device includes a second non-safety-level display, combined with a keyboard and mouse, for the operator to perform monitoring and control operation tasks of the heating reactor; the second non-safety-level computer device of each operation monitoring unit 11 can monitor and control all operating parameters and / or required working screens of the corresponding reactor unit; the normal start and stop of the reactor unit can be completed by the second non-safety-level computer device of the operation monitoring unit 11, that is, the operation monitoring unit 11 can complete the basic monitoring and control operations of each reactor unit when it is working normally. Further, each operation monitoring unit 11 can have four second non-safety-level displays, two hosts, two sets of mice and keyboards to facilitate the operator's work. When one of the operation monitoring units 11 fails, one of the hosts of another operation monitoring unit 11 can be used to control two second non-safety-level displays to display the working information of the No. 1 reactor unit, and another host of the operation monitoring unit 11 can be used to control the other two second non-safety-level displays to display the working information of the No. 2 reactor unit; the operator can also choose to retreat to the second workbench 2 and log in with authority to make the second workbench 2 enter the monitoring mode.

[0053] See also Figure 1-2 As an optional embodiment of the present case, each of the operation monitoring units 11 includes a second non-safety level computer device, and each of the operation monitoring units 11 is configured to monitor the operating parameters and / or working screens of any or all of the reactor units by switching monitoring accounts.

[0054] It should be noted that the operation monitoring unit 11 can receive and process data from each reactor unit in real time, and support real-time data analysis; by quickly switching the monitoring account, the operator can choose to monitor a single or multiple reactor units as needed, so that when an operation monitoring unit 11 fails, another operation monitoring unit 11 can be used to temporarily replace the monitoring, thereby ensuring the normal monitoring and control of the operation of the two reactor units, and then ensuring the safe operation of the entire heating reactor, improving the redundancy of the entire system, reducing the risk of single point failures, and ensuring the continuous and safe operation of the nuclear power plant.

[0055] See also Figure 1-2 As an optional embodiment of the present case, the display unit group 3 is provided with an alarm unit 33, and each of the alarm units 33 is provided with a differentiated alarm prompt information corresponding to the alarm of the reactor unit.

[0056] It should be noted that when each of the alarm units 33 alarms, the alarm sound is differentiated by unit in the display screen and alarm design, the unit number information is prompted when the alarm is triggered, and the unit number information is marked in the screen header to reduce the interference to the operator when two reactor units are running at the same time. Reducing interference not only improves the performance of a single alarm unit 33, but also optimizes the stability and reliability of the entire alarm system; at the same time, different alarm prompt information enables operators to intuitively identify the specific source of the alarm, clearly distinguish the alarm information, reduce false alarms and omissions caused by confusion or coverage, and improve the accuracy of the alarm system. For example, operators can more quickly filter out alarms that need to be handled first from multiple alarms, simplifying the decision-making process; clear alarm prompt information reduces the psychological pressure of operators in emergency situations and improves the efficiency of handling alarms.

[0057] See also Figure 1-2 As an optional embodiment of the present case, when the alarm unit 33 sounds an alarm, each of the operation monitoring units 11 is configured to display a list of all alarm events of the corresponding reactor unit or the heating reactor as a whole.

[0058] It should be noted that when the alarm unit 33 is triggered, all relevant alarm events can be instantly obtained through the operation monitoring units 11, which helps the operator to conduct a comprehensive diagnosis of abnormal conditions, ensure that no alarm events are missed, and each signal receives proper attention and processing, thereby reducing the risk of accidents; by instantly displaying all alarm events, operators can quickly identify fault points or abnormal areas, shortening the problem location time, and the immediately visible alarm list provides operators with information support for making quick decisions, especially when multiple events occur, helping to determine processing priorities.

[0059] See also Figure 1-2 As an optional embodiment of the present case, the alarm unit 33 is an alarm light-emitting sign device, and the first workbench 1 is provided with independent control buttons for silencing the alarm and / or confirming the alarm and / or resetting the alarm of the alarm unit 33.

[0060] It should be noted that in the main control room of the heating reactor, the alarm system is a key facility to ensure safety and continuous operation. Reasonably configured alarm unit 33 and its auxiliary operation equipment can significantly improve the processing efficiency and accuracy in emergency situations. The alarm light sign device quickly attracts the attention of the operator by lighting up the light sign, making the alarm information transmission concise and clear, and reducing the reaction time; the information on the light sign usually contains the source and type of the alarm, helping the operator to quickly identify the problem, shortening the problem diagnosis time, thereby achieving the purpose of quickly locating the problem; the independent control button is specially designed for the alarm light sign device, and the function keys (mute, confirm, reset) with clear markings are used to reduce the misoperation caused by complex operations. The (mute, confirm, reset) buttons set separately allow the operator to choose the appropriate response mode according to the specific situation, such as only eliminating the sound, confirming the alarm or resetting the system, which improves the accuracy of handling the alarm. The independent control button is located on the first workbench 1, and the convenient operation position layout provides a good human-computer interaction interface, increases the ease of operation, and at the same time, the operator does not need to move for a long time or frequently to respond to different alarms, thereby reducing the physical burden in long-term work. An independent mute button can temporarily stop the alarm, reducing the pressure on the operator, so that he can deal with continuous or multiple alarms more calmly; the confirmation and reset functions ensure that each alarm is properly responded to and allow the system to be reset and ready to record new alarms. After receiving the alarm, the operator can operate directly at the first workbench 1 without having to go to the remote control panel, saving valuable time; due to the independence and centralized setting of the control buttons, the operator can quickly execute a variety of operating instructions, improving work efficiency.

[0061] See also Figure 3 The present invention provides a control center of a heating reactor, including the main control room of the heating reactor, so that the control center of the heating reactor is also within the protection scope of this case.

[0062] See also Figure 3 As an optional embodiment of the present case, the control center of the heating reactor further includes an auxiliary function room, and the auxiliary function room and the main control room 100 are located on the same floor;

[0063] The auxiliary function rooms include at least several or all of the shift office, the duty officer's room, the isolation office, the restaurant, the toilet, the computer room, the technical support center, the dressing room, and the duty officer's room.

[0064] It should be noted that if Figure 3As shown in the figure, D is the shift office, E is the isolation office, F is the small three-box room, G is the technical support center, H is the locker room, I is the corridor, J is the computer room, K is the restaurant and / or sanitary napkin, L is the duty officer's room, M is the stairwell, and N is the hoisting hole. The setting of the auxiliary function room in this case concentrates multiple functional areas such as the shift office, duty officer's room, isolation office, restaurant, toilet, computer room, technical support center, locker room, etc. This layout is not only convenient for the work handover and daily management of personnel, but also convenient for the daily life and technical support of personnel, thereby improving the operation efficiency and management level of the nuclear power plant. For example, by setting up auxiliary function rooms on the same floor, the control and management are centralized, the movement time of personnel in the plant is reduced, and work efficiency is improved; the setting of the duty room and the technical support center enables key decisions and emergency responses to be processed in the first time, enhancing the nuclear power plant's ability to handle emergencies; each function room is professionally designed and configured according to its functions, so that each department can focus more on the work within its scope of responsibility, improving the professionalism and efficiency of the work; the setting of living facilities such as restaurants, toilets, and changing rooms provides employees with a better working and living environment, and enhances their sense of belonging and satisfaction. Therefore, the setting of auxiliary function rooms not only improves the operating efficiency and management level of the nuclear power plant, optimizes personnel allocation, improves safety levels, promotes information exchange and technology sharing, reduces operating costs, and meets the convenience of use.

[0065] See also Figure 3 As an optional embodiment of the present case, at least part of the auxiliary function rooms are arranged around the main control room 100, and a corridor connecting the main control room 100 and at least part of the auxiliary function rooms is also provided on the side of the main control room 100.

[0066] The main control room 100 is located in the center of the electrical area of ​​the auxiliary plant. The supporting auxiliary function rooms include the shift office, the duty officer's room, the isolation office, the restaurant, the computer room, the technical support center and other rooms are all around the main control room 100 and arranged on the same floor, so as to reduce the free volume of the area, thereby reducing the technical requirements for the emergency ventilation system, thereby achieving a more economical goal.

[0067] This case realizes a central monitoring of two small heating reactor units in one main control room 100. When each unit is in steady-state operation, one operator can monitor the two reactor units at the same time, reducing the number of human-machine interfaces and operators, improving the economy of the heating reactor units, and setting up necessary diversified monitoring means to meet the requirements of stable and safe operation of each unit. In the display screen and alarm design, the alarm sound is distinguished by unit, the unit number information is prompted when the alarm is triggered, and the unit number information is marked in the screen header, reducing the interference and human error of the dual reactor operation on the operator.

[0068] In this case, by setting the first non-safety-level computer equipment and light-emitting sign equipment of the safety monitoring unit 12 as diversified information display and operation means, the two reactor units can be monitored in the event that the operation monitoring unit 11 and / or the display unit group 3 all fail; the configuration scheme of the operation monitoring unit 11, when a certain operation monitoring unit 11 fails, the operator can use the account authority control on another operation monitoring unit 11 to achieve one operator monitoring the operation of two reactor units at the same time; when the first non-safety-level computer and alarm light-emitting sign equipment of the safety monitoring unit 12 also fail, the safety-level switch on the safety monitoring station can achieve emergency shutdown, dedicated triggering and other safety operations, and the first safety-level computer equipment can still display the reactor protection system parameters and post-accident parameters; it should be understood that all display screens involved in this case can be touch screens for easy operation.

[0069] In this case, during normal operation, the operator monitors each reactor unit through the operation monitoring unit 11 and the display unit group 3, and the safety monitoring unit 12 is in hot standby mode at this time; if a large screen or all of the display unit group 3 is unavailable, it does not affect the operator's monitoring of the reactor unit through the operation monitoring unit 11; if a screen or a host on the operation monitoring unit 11 is unavailable, it does not affect the operator's monitoring of the reactor unit; if a certain operation monitoring unit 11 is unavailable, the operator can switch between units in another operation monitoring unit 11 by switching accounts; the large screen of the display unit group 3, the operation monitoring unit 11, and the second workbench 2 All equipment belongs to the computer information and control system. If the system is unavailable, the operator continues to monitor the reactor unit through the first safety level computer equipment on the safety monitoring unit 12, combined with the alarm information provided by the light-emitting sign equipment (the "auxiliary information and control equipment" is composed of a non-safety level touch screen + alarm light-emitting sign equipment + a group of alarm mute / alarm confirmation / alarm reset buttons, which is independent of the computer information and control system and serves as a backup monitoring method, providing a minimum number of basic display signals, and providing sound and light alarms, power control, alarm operations and other functions. The reactor unit does not need to reduce power or shut down, and the equipment of the computer information and control system can be repaired within the specified time frame. If the maintenance of the computer information and control system equipment is completed within the specified time, monitoring will continue through the large-screen mode of the operation monitoring unit 11 and the display unit group 3; if the maintenance is not completed, the reactor unit will be withdrawn and the power will be reduced and the reactor will be shut down through the rod control function (manual control by the operator) of the first non-safety-level computer equipment of the safety monitoring unit 12; if the computer information and control system is unavailable and the superimposed first non-safety-level computer equipment is unavailable, the safety level switch of the safety monitoring unit 12 will be used to shut down the reactor unit and automatically enter a safe shutdown state.
