Description

Technical Field

[0001] This invention relates to the field of nuclear power technology, specifically to a method, apparatus, and equipment for handling ATWS accidents in a high-temperature gas-cooled reactor. Background Technology

[0002] Anticipated Transient Without Scram (ATWS) accidents are rare, over-design-baseline (OTBS) accidents. When an ATWS occurs and the reactor safety protection system is required to initiate an emergency shutdown, if the control rod system fails and an emergency shutdown cannot be achieved by control rods falling into the reflector, the main helium blower will shut down and the secondary coolant will be isolated. This prevents the continued removal of heat from the core through forced circulation in the primary and secondary coolants, causing fuel element temperatures to rise and the accident to escalate. Without effective control, the primary coolant safety valves will open, leading to the release of primary coolant. Therefore, effective strategies and methods for handling this accident are crucial to effectively control it and reduce radioactive material emissions. Current technology lacks effective methods for handling ATWS accidents in high-temperature gas-cooled reactors and cannot effectively control this type of accident. Summary of the Invention

[0003] In view of this, the present invention provides a method, apparatus and equipment for handling ATWS accidents in high-temperature gas-cooled reactors, in order to solve the problem that the prior art lacks a method for handling ATWS accidents in high-temperature gas-cooled reactors, and cannot effectively control the accident and reduce the emission of radioactive materials.

[0004] In a first aspect, the present invention provides a method for handling ATWS accidents in a high-temperature gas-cooled reactor, the method comprising:

[0005] Step S1: Generate an ATWS incident signal based on preset fault triggering conditions;

[0006] Step S2: Based on the ATWS incident signal, control the safety bar and regulating bar to fall, and determine whether the sum of the number of safety bars and regulating bars inserted into the bottom of the pile is less than the preset number. Otherwise, generate an ATWS incident handling completion signal; otherwise, proceed to step S3.

[0007] Step S3: Control the compensating bar to fall, and determine whether the sum of the number of safety bars, adjusting bars and compensating bars inserted into the bottom of the pile is less than the preset number. Otherwise, generate an ATWS accident handling completion signal. If yes, proceed to step S4.

[0008] Step S4: Control the power distribution panel to cut off the power to trigger the safety bar, adjusting bar, and compensating bar to fall, and determine whether the sum of the number of safety bars, adjusting bars, and compensating bars inserted into the bottom of the pile is less than the preset number. Otherwise, generate an ATWS accident handling completion signal; otherwise, proceed to step S5.

[0009] Step S5: Control the falling absorption ball of the preset diameter, monitor whether the absorption ball falls successfully, if so, generate an ATWS accident handling completion signal, otherwise execute step S6;

[0010] Step S6: Control the unloading of fuel elements from the reactor core and generate an ATWS accident handling completion signal.

[0011] The high-temperature gas-cooled reactor (ATWS) accident handling method provided in this embodiment is based on the principles of convenient operation and rapid control response. It adopts a staged handling approach, which can effectively control the accident without the need for temporary measures or additional procurement. It can mitigate the consequences of the accident, reduce the temperature rise of fuel elements, prevent the opening of safety valves, reduce the release of radioactive materials, and ensure the safety of the reactor.

[0012] In one optional implementation, step S1 includes:

[0013] The system monitors the number of safety bars and control bars inserted into the bottom of the stack and the intermediate range power in real time. When the sum of the number of safety bars and control bars inserted into the bottom of the stack is less than a preset number or the intermediate range power is greater than a preset value, an ATWS (Automatic Threat Response System) fault signal is generated.

[0014] In practical applications, the embodiments of the present invention can monitor the number of safety rods and regulating rods inserted by using sensors over time, or can monitor the power at intermediate ranges to monitor the safety rods and regulating rods. By providing multiple monitoring methods, reasonable settings can be made according to actual conditions.

[0015] In one optional implementation, step S2, which controls the drop of the safety bar and the regulating bar based on the ATWS accident occurrence signal, includes:

[0016] An emergency shutdown alert signal is generated based on the ATWS incident signal, and the emergency shutdown actions triggered by the operation and maintenance personnel based on the emergency shutdown alert signal are obtained to control the descent of the safety rods and regulating rods.

[0017] This invention effectively guides maintenance personnel to perform control operations by generating an emergency shutdown warning signal, thereby triggering the safety bar and regulating bar to fall again in a timely manner.

[0018] In one optional implementation, step S3, controlling the falling of the compensation rod, includes:

[0019] A cold shutdown alert signal is generated, and the cold shutdown action triggered by the operation and maintenance personnel based on the cold shutdown alert signal is obtained to control the fall of the compensating rods.

[0020] This invention effectively guides maintenance personnel to perform control operations by generating a cold shutdown warning signal, thereby triggering the timely descent of the compensating rods.

[0021] In one optional implementation, step S4, controlling the power outage of the distribution panel to trigger the safety bar, adjusting bar, and compensating bar to fall, includes:

[0022] A power outage warning signal is generated, and the power outage action of the distribution panel triggered by the power outage warning signal is obtained by the operation and maintenance personnel to control the descent of the safety bar, regulating bar, and compensating bar.

[0023] This invention effectively guides maintenance personnel to perform control operations by generating a power failure warning signal, thereby disconnecting the power supply to the distribution panel in a timely manner, allowing the safety rod, regulating rod, and compensating rod to fall under their own weight.

[0024] In one optional implementation, step S5, controlling the falling of an absorbent sphere of a preset diameter, includes:

[0025] A signal indicating the fall of the absorption ball is generated, and the operation and maintenance personnel trigger the fall of the absorption ball of a preset diameter based on the signal to control the fall of the absorption ball.

[0026] This invention provides an embodiment that guides maintenance personnel to perform absorption ball control operations in an orderly manner by generating a falling absorption ball prompt signal. This allows maintenance personnel to know that the accident status cannot be resolved by manipulating the control rod and that the accident needs to be handled by dropping the ball.

[0027] In an optional implementation, step S6 involves controlling the unloading of fuel elements from the reactor core and generating an ATWS accident handling completion signal, including:

[0028] Generate a discharge prompt signal;

[0029] The system acquires the information from maintenance personnel based on the unloading prompt signal to complete the unloading of the reactor core fuel elements and generates an unloading completion signal.

[0030] An ATWS (Accident Handling Complete Signal) is generated based on the unloading completion signal.

[0031] In this embodiment of the invention, if the ball dropping process still cannot complete the ATWS incident handling, a discharge prompt signal is generated to guide maintenance personnel to discharge the fuel elements of the reactor core through the discharge pipeline, thereby reducing the fuel load of the reactor core and completing the ATWS incident handling.

[0032] Secondly, the present invention provides an ATWS (Atmospheric Temperature Strike Wind Troubleshooting) device for high-temperature gas-cooled reactors, the device comprising:

[0033] The monitoring module is used to generate ATWS accident signals based on preset fault triggering conditions;

[0034] The first accident handling module is used to control the safety bar and the regulating bar to fall based on the ATWS accident occurrence signal, and to determine whether the number of safety bars and regulating bars inserted into the bottom of the pile is less than the preset number. Otherwise, an ATWS accident handling completion signal is generated; otherwise, the second accident handling module is executed.

[0035] The second accident handling module is used to control the falling of the compensating rod and determine whether the sum of the number of safety rods, adjusting rods and compensating rods inserted into the bottom of the stack is less than the preset number. Otherwise, an ATWS accident handling completion signal is generated; otherwise, the third accident handling module is executed.

[0036] The third accident handling module is used to control the power outage of the distribution panel to trigger the safety bar, regulating bar, and compensating bar to fall, and to determine whether the sum of the number of safety bars, regulating bars, and compensating bars inserted into the bottom of the pile is less than the preset number. Otherwise, an ATWS accident handling completion signal is generated; otherwise, the fourth accident handling module is executed.

[0037] The fourth accident handling module is used to control the falling absorption ball of a preset diameter and monitor whether the absorption ball has fallen successfully. If it has, an ATWS accident handling completion signal is generated; otherwise, the fifth accident handling module is executed.

[0038] The fifth accident handling module is used to control the unloading of fuel elements from the reactor core and generate an ATWS accident handling completion signal.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] This invention provides a method for handling ATWS accidents in a high-temperature gas-cooled reactor. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer device such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0049] This embodiment provides a method for handling ATWS accidents in a high-temperature gas-cooled reactor, which can be used in control console equipment associated with a high-temperature gas-cooled reactor. Figure 1 This is a flowchart of the ATWS accident handling method for a high-temperature gas-cooled reactor according to an embodiment of the present invention, as follows: Figure 1 As shown, the process includes the following steps:

[0050] Step S1: Generate an ATWS accident occurrence signal based on preset fault triggering conditions.

[0051] Specifically, in this embodiment, an ATWS incident refers to an incident in which the adjusting bar and safety bar, which should have automatically fallen under accident conditions, fail to fall automatically. For example... Figure 2 The schematic diagram of the high-temperature gas-cooled reactor system shown includes safety rods and regulating rods (1), compensation rods (2), an absorber ball shutdown system (3), and a discharge pipe (4). In this embodiment of the invention, the number of safety rods and regulating rods (1) inserted into the reactor bottom and the intermediate range power are monitored in real time. When the sum of the number of safety rods and regulating rods inserted into the reactor bottom is less than a preset number or the intermediate range power is greater than a preset value, an ATWS (Automatic Temperature Controller System) accident signal is triggered.

[0052] In one specific embodiment, when the number of safety rods and regulating rods inserted is less than 9 or the intermediate range power is greater than 12.5MW, an audible and visual alarm signal is triggered as an ATWS (Automatic Automated Warp Drive) accident signal, indicating that the ATWS accident state has been entered. It should be noted that an intermediate range power greater than 12.5MW will result in fewer than 9 safety rods and regulating rods inserted. In practical applications, the number of safety rods and regulating rods inserted can be monitored in real time by sensors, or the control rods can be monitored by monitoring the intermediate range power.

[0053] Step S2: Based on the ATWS incident signal, control the safety bar and regulating bar to fall, and determine whether the sum of the number of safety bars and regulating bars inserted into the bottom of the pile is less than the preset number. Otherwise, generate an ATWS incident handling completion signal; otherwise, proceed to step S3.

[0054] Specifically, the console generates an emergency shutdown prompt signal based on the ATWS incident signal; it obtains the emergency shutdown action triggered by the maintenance personnel based on the emergency shutdown prompt signal to control the descent of the safety rods and regulating rods. For example, when entering the ATWS incident state, an audible and visual alarm signal is generated at the same time as the emergency shutdown prompt signal. The maintenance personnel are attracted by the audible and visual alarm signal. By generating the emergency shutdown prompt signal, the maintenance personnel are effectively guided to perform control operations. By manually triggering the emergency shutdown, the safety rods and regulating rods (1) are triggered to fall again. If the number of safety rods and regulating rods inserted into the bottom of the reactor is greater than 9, the ATWS incident condition can be exited. If the number of safety rods and regulating rods inserted into the bottom of the reactor is still less than 9, then step S3 continues.

[0055] Step S3: Control the compensating rod to fall, and determine whether the sum of the number of safety rods, adjusting rods, and compensating rods inserted into the bottom of the pile is less than the preset number. Otherwise, generate an ATWS accident handling completion signal; otherwise, execute step S4.

[0056] Specifically, when the number of safety rods and regulating rods inserted into the reactor bottom after triggering the emergency shutdown action is still less than 9, the maintenance personnel are effectively guided to perform control operations by generating a cold shutdown prompt signal. The maintenance personnel control the compensating rod (2) to fall based on the cold shutdown action triggered by the cold shutdown prompt signal. At this time, if the sum of the number of safety rods, regulating rods and compensating rods inserted into the reactor bottom is greater than 9, the ATWS accident condition can be exited. If it is still less than 9, step S4 is continued.

[0057] In this embodiment of the invention, if the reactor is still in an ATWS (Automatic Trial and Shutdown) state after an emergency shutdown, the cold shutdown is triggered based on the consideration of operational convenience, as the cold shutdown button is located on the control panel in the main control room, which can reduce the processing time.

[0058] Step S4: Control the power distribution panel to cut off to trigger the safety bar, regulating bar, and compensating bar to fall, and determine whether the sum of the number of safety bars, regulating bars, and compensating bars inserted into the bottom of the pile is less than the preset number. Otherwise, generate an ATWS accident handling completion signal. If yes, proceed to step S5.

[0059] Specifically, by generating a power outage warning signal and obtaining the power outage action of the distribution panel triggered by the power outage warning signal by the maintenance personnel, the descent of safety rods, regulating rods, and compensating rods is controlled. This embodiment of the invention effectively guides maintenance personnel to perform control operations by generating a power outage warning signal, thereby timely disconnecting the power supply to the distribution panel. In the event of power failure, the control rods (safety rods, regulating rods, and compensating rods) will descend under the influence of gravity, falling from the top of the reactor to the bottom. If, due to deformation of the control rod channels caused by earthquakes or other reasons, the number of descended control rods is still less than nine, step S5 is continued; otherwise, the ATWS accident handling is completed. In this step, the preferred method for handling the accident is still through the control rods, minimizing the use of absorber balls. This is because after the absorber balls fall, restarting the reactor requires blowing them back from the side reflector layer into the storage tank, which is relatively cumbersome.

[0060] Step S5: Control the falling absorption ball of a preset diameter, monitor whether the absorption ball falls successfully, if so, generate an ATWS accident handling completion signal, otherwise execute step S6.

[0061] Specifically, a falling absorber ball warning signal is generated, and the operation and maintenance personnel trigger the falling action of the absorber ball with a preset diameter based on the falling absorber ball warning signal (e.g., pressing the absorber ball control falling button) to control the falling absorber ball. If the ATWS fault state is still present after a power outage, it indicates that the control rods are no longer sufficient (there are definitely fewer than 9 rods), and the only solution is to fall the absorber ball. This embodiment of the invention guides the operation and maintenance personnel to perform absorber ball control operations in an orderly manner by generating a falling absorber ball warning signal, thereby letting the operation and maintenance personnel know that the fault state cannot be resolved by controlling the control rods and that the fault needs to be resolved by falling the absorber ball.

[0062] In one specific embodiment, a boron-containing absorber ball with a diameter of 6 mm is used to control the absorber ball shutdown system (3) to terminate the fission reaction. Since the absorber ball has a small diameter, there is no situation where it gets stuck or cannot fall. If the absorber ball still fails to fall, step S6 is executed. Otherwise, the ATWS accident handling is completed.

[0063] Step S6: Control the unloading of fuel elements from the reactor core and generate an ATWS accident handling completion signal.

[0064] Specifically, if the ball dropping process still cannot complete the ATWS incident handling, a refueling prompt signal is generated; the operation and maintenance personnel complete the unloading of the core fuel elements based on the refueling prompt signal, and a refueling completion signal is generated; an ATWS incident handling completion signal is generated based on the refueling completion signal. In one embodiment, when the operation and maintenance personnel unload the core fuel elements through the refueling pipe (4) according to the refueling prompt signal, the amount of fuel loaded in the core is reduced (the specific amount is reasonably selected according to the actual incident situation), thereby completing the ATWS incident handling.

[0065] The high-temperature gas-cooled reactor (ATWS) accident handling method provided in this embodiment is based on the principles of convenient operation and rapid control response. It adopts a staged handling approach, which can effectively control the accident without the need for temporary measures or additional procurement. It can mitigate the consequences of the accident, reduce the temperature rise of fuel elements, prevent the opening of safety valves, reduce the release of radioactive materials, and ensure the safety of the reactor.

Otherwise, it generates an ATWS accident handling completion signal, and if so, it executes the second accident handling module.

[0069] The second accident handling module 303 is used to control the falling of the compensating rod and determine whether the sum of the number of safety rods, adjusting rods and compensating rods inserted into the bottom of the stack is less than the preset number. Otherwise, an ATWS accident handling completion signal is generated; otherwise, the third accident handling module is executed.

[0070] The third accident handling module 304 is used to control the power outage of the distribution panel to trigger the safety bar, regulating bar, and compensating bar to fall, and to determine whether the sum of the number of safety bars, regulating bars, and compensating bars inserted into the bottom of the pile is less than the preset number. Otherwise, an ATWS accident handling completion signal is generated; otherwise, the fourth accident handling module is executed.
