Description

Technical Field

[0001] The embodiments disclosed herein belong to the field of nuclear power technology, specifically relating to a method and system for identifying and handling flow obstruction faults in a high-temperature reactor fuel loading and unloading system. Background Technology

[0002] High-temperature gas-cooled reactors operate using spherical fuel elements. The HTR-PM (High Temperature Reactor-Pebblebed Modules) fuel loading and unloading system removes fuel spheres from the bottom of the reactor using the core unloading device. The fuel spheres flow by gravity within the fuel loading and unloading system pipelines. After fragmentation, burnup measurement, and single-item delivery, at the lowest point of the system, reusable or newly added fuel spheres are lifted by airflow within the fuel loading and unloading system pipelines to the top of the reactor and fall into the core, thus achieving continuous refueling of the high-temperature reactor without stopping the reactor.

[0003] The flow baffle is a proprietary piece of equipment in the fuel loading and unloading system of a high-temperature gas-cooled reactor. Located in the start-up section of the pneumatic lifting system, it is used for gas flow obstruction and single-fuel element delivery, and is a key transfer and conversion device in the fuel cycle. During the commissioning of the high-temperature reactor demonstration project, flow baffle failures in the fuel loading and unloading system occurred frequently. Due to the complexity of the system failure types and the high radiation dose at the equipment site, flow baffle failures were difficult to identify, thus affecting the efficiency of resolving flow baffle failures and consequently restricting the overall cycle efficiency of the fuel loading and unloading system. Summary of the Invention

[0019] If the gas flow rate within a predetermined time is greater than the first flow rate threshold, it is determined that the number of temporary balls in the downstream pipe section is less than the second ball number threshold.

[0020] In some embodiments of the present invention, determining whether the number of temporarily stored balls in the connecting pipe section is abnormal further includes:

[0022] Based on the gas flow rate being less than or equal to a first flow rate threshold within a predetermined time, it is determined that the number of temporary storage balls in the downstream pipe section is greater than or equal to a second ball number threshold, and the number of temporary storage balls in the downstream pipe section is normal.

[0023] If the gas flow rate within a predetermined time is less than or equal to the second flow rate threshold, it is determined that there is a lifting fault in the downstream pipe section.

[0024] Wherein, the first flow threshold is greater than the second flow threshold.

[0025] In some embodiments of the present invention, after determining that the flow restrictor is faulty, the method further includes:

[0026] Control the rotor of the flow restrictor to rotate in the reverse direction;

[0034] In some embodiments of the present invention, after determining that the fault of the current blocker has been cleared, the following steps are further included, where the current blocker is operating normally:

[0035] Manually empty the temporary ball in the connecting pipe section.

[0036] The second invention proposes a flow obstruction fault identification and processing system for a high-temperature reactor fuel loading and unloading system. This system is used to execute the flow obstruction fault identification and processing method for a high-temperature reactor fuel loading and unloading system according to any of the above embodiments. The high-temperature reactor fuel loading and unloading system includes: a flow obstruction assembly, which includes a flow obstruction and a connecting pipe section. The connecting pipe section includes an upstream pipe section and a downstream pipe section, which are respectively connected to the flow obstruction. The system is characterized by comprising:

[0037] The acquisition module is used to acquire the operating status of the flow restrictor and to acquire the number of temporary balls in the connecting pipe section;

This method acquires the operating status of the flow obstruction, determines whether the operating status is abnormal, acquires the number of temporary balls in the connecting pipe section of the flow obstruction, and determines whether the number of temporary balls in the connecting pipe section is abnormal. Based on both the abnormal operating status of the flow obstruction and the abnormal number of temporary balls in the connecting pipe section, a flow obstruction fault is determined.

[0041] Figure 2 for Figure 1 The logic flowchart for step 400 is shown below;

[0042] Figure 3 The present disclosure provides a flowchart of the flow barrier fault handling steps in the flow barrier fault identification and handling method for a high-temperature reactor fuel loading and unloading system according to an embodiment of the present disclosure. Detailed Implementation

[0043] To enable those skilled in the art to better understand the technical solutions of this disclosure, the disclosure will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] like Figures 1 to 3 As shown, a method for identifying and handling flow obstruction faults in a high-temperature reactor fuel loading and unloading system is disclosed. The high-temperature reactor fuel loading and unloading system includes a flow obstruction assembly, which comprises an upstream pipe section, a downstream pipe section, and a flow obstruction, wherein the flow obstruction is connected to the upstream pipe section and the downstream pipe section respectively. The method includes:

[0045] S100: Obtain the operating status of the flow restrictor;

[0046] S200: Determine whether the operating status of the flow restrictor is abnormal;

[0047] S300: Obtain the number of temporarily stored balls in the connecting pipe section;

[0048] S400: Determine whether the number of temporarily stored balls in the connecting pipe section is abnormal;

[0049] S500: Based on the abnormal operating status of the flow restrictor and the abnormal number of temporary balls in the connecting pipe section, the flow restrictor is determined to be faulty.

[0050] The method for identifying and processing flow obstruction faults in a high-temperature reactor fuel loading and unloading system according to an embodiment of the present invention acquires the operating status of the flow obstruction, determines whether the operating status of the flow obstruction is abnormal, acquires the number of temporary balls in the connecting pipe section of the flow obstruction, and determines whether the number of temporary balls in the connecting pipe section is abnormal. Based on the abnormal operating status of the flow obstruction and the abnormal number of temporary balls in the connecting pipe section, a flow obstruction fault is determined. The method of this embodiment of the present invention can quickly identify flow obstruction faults, thereby improving the overall cycle efficiency of the high-temperature reactor fuel loading and unloading system.

[0051] It should be noted that the method of the present invention does not restrict the order of the steps of obtaining the operating status of the flow restrictor and obtaining the number of temporary balls in the upstream pipe section connected to the flow restrictor and the number of temporary balls in the downstream pipe section connected to the flow restrictor. The order of the above steps has no effect on the judgment of the flow restrictor fault. The above steps can be performed simultaneously, or the step of obtaining the operating status of the flow restrictor can be performed first and then the number of temporary balls in the connecting pipe section can be obtained, or the number of temporary balls in the connecting pipe section can be obtained first and then the step of obtaining the operating status of the flow restrictor can be performed.

[0052] In some embodiments of the present invention, determining whether the operating state of the current blocker is abnormal includes:

[0053] S201: Based on the fact that the rotor speed of the flow restrictor is less than the speed threshold, it is determined that the operating state of the flow restrictor is abnormal.

[0054] After obtaining the rotor speed of the flow restrictor, the rotor speed is compared with a speed threshold. When the rotor speed is less than the speed threshold, it indicates that the rotor speed of the flow restrictor is abnormal, that is, the operating state of the flow restrictor is abnormal. Specifically, when a foreign object falls between the rotor and the outer casing of the flow restrictor and the rotor can still rotate, the rotor speed may be slightly lower than the speed threshold, or it may be much lower than the speed threshold. When the rotor is stuck in a certain position inside the casing, the rotor speed may be zero, that is, the rotor cannot rotate inside the casing, and the rotor remains stationary.

[0055] In this embodiment, the rotational speed of the choke rotor can be directly measured by a sensor, or the rotational speed of the rotor's drive device (such as a motor) can be measured by a sensor to determine the rotor's rotational speed. It should be noted that the rotational speed threshold in this embodiment can be 0.5 r / s, 1 r / s, 2 r / s, 5 r / s, or other rotational speed values; this embodiment of the invention does not limit the rotational speed threshold.

[0056] In some embodiments of the present invention, determining whether the operating state of the current blocker is abnormal includes:

[0057] S202: Based on the abnormal position of the rotor of the flow restrictor, it is determined that the operating state of the flow restrictor is abnormal.

[0058] The position information of the rotor of the flow restrictor is obtained over a period of time. If the rotor remains stationary at a certain position for a certain period of time, it is determined that the rotor position of the flow restrictor is abnormal, that is, the operating state of the flow restrictor is abnormal. Specifically, the certain period of time can be ten seconds, twenty seconds, thirty seconds, forty seconds, fifty seconds, one minute, two minutes, or other time periods. This embodiment of the invention does not limit the certain time period. The certain position specifically refers to any position of the rotor between the upstream pipe section and the downstream pipe section. In most cases, the certain position is close to the upstream pipe section or the downstream pipe section, that is, the ball is mostly stuck at the position where the rotor enters the upstream pipe section, or the position where the rotor connects to the downstream pipe section.

[0059] In some embodiments of the present invention, determining whether the number of temporarily stored balls in the connecting pipe section is abnormal includes:

[0060] S401: If the number of temporary balls in the upstream pipe section is greater than the first ball count threshold, it is determined that the number of temporary balls in the upstream pipe section is abnormal.

[0061] When the flow restrictor becomes stuck, the balls in the upstream pipe section connected to the flow restrictor cannot enter the flow restrictor, causing the balls to accumulate in the upstream pipe section. The number of balls in the upstream pipe section is obtained from a counter. If the number of temporarily stored balls in the upstream pipe section is greater than a first ball count threshold, it indicates that the balls in the upstream pipe section are accumulating, and the flow restrictor may be stuck. Further confirmation is needed to determine if the flow restrictor is stuck. Specifically, the first ball count threshold can be 5, 10, 15, 20, 25, or 30, or other values. This embodiment does not limit the first ball count threshold.

[0062] In some embodiments of the present invention, determining whether the number of temporarily stored balls in the connecting pipe section is abnormal includes:

[0063] S402: If the number of temporary balls in the downstream pipe section is less than the second ball count threshold, it is determined that the number of temporary balls in the downstream pipe section is abnormal.

[0064] When the flow obstructor jams, it cannot transfer the balls from the upstream pipe section to the downstream pipe section. The balls in the downstream pipe section are then continuously transported to the next device, causing the number of balls temporarily stored in the downstream pipe section to fall below the second ball count threshold. Therefore, when the number of temporarily stored balls in the downstream pipe section is less than the second ball count threshold, it can be determined that the number of temporarily stored balls in the downstream pipe section is abnormal. Specifically, the second ball count threshold can be 1, 2, or 3, or it can be other values. This embodiment does not limit the second ball count threshold.

[0065] In some embodiments of the present invention, determining that the number of temporary balls in the downstream pipe section is abnormal based on the number of temporary balls in the downstream pipe section being less than a second ball count threshold includes:

[0066] S4021: Based on the fact that the counter in the downstream pipe section has not obtained the number of temporary balls in the downstream pipe section, obtain the gas flow rate in the downstream pipe section within a predetermined time.

[0067] S4022: Based on the gas flow rate being greater than the first flow rate threshold within a predetermined time, it is determined that the number of temporary balls in the downstream pipe section is less than the second ball number threshold.

[0068] If the counter in the downstream pipe section does not detect any fuel balls passing through for a period of time, it indicates that the temporary fuel balls are accumulating in the upstream pipe section, or that the temporary fuel balls in the downstream pipe section have been completely transported to the next device. In this case, it is necessary to determine the issue by measuring the gas flow rate in the downstream pipe section. The gas flow rate of the downstream pipe section is obtained within a predetermined time period. When the gas flow rate of the downstream pipe section is consistently greater than a first flow rate threshold within this predetermined time period, the number of temporary fuel balls in the downstream pipe section is less than a certain value. Specifically, the more temporary fuel balls there are in the downstream pipe section, the smaller the gas flow rate at the outlet of the downstream pipe section will be, assuming the inlet flow rate remains constant. Therefore, when the gas flow rate at the outlet of the downstream pipe section is greater than the first flow rate threshold within the predetermined time period, the number of temporary fuel balls in the downstream pipe section is less than a second ball count threshold.

[0069] S4021: Based on the fact that the counter in the downstream pipe section has not obtained the number of temporary balls in the downstream pipe section, obtain the gas flow rate in the downstream pipe section within a predetermined time.

[0070] S4023: Based on the gas flow rate being less than or equal to a first flow rate threshold within a predetermined time, it is determined that the number of temporary storage balls in the downstream pipe section is greater than or equal to a second ball number threshold, and the number of temporary storage balls in the downstream pipe section is normal.

[0071] S4024: If the gas flow rate within a predetermined time is less than or equal to the second flow threshold, it is determined that there is a lifting fault in the downstream pipe section.

[0072] Wherein, the first flow threshold is greater than the second flow threshold.

[0073] When the gas flow rate in the downstream pipe section is less than or equal to the first flow rate threshold within the predetermined time period, it indicates that the number of temporary storage balls in the downstream pipe section is large. A large number of temporary storage balls in the downstream pipe section significantly affects the gas velocity at the outlet end of the downstream pipe section, thus significantly affecting the gas flow rate in the downstream pipe section within the predetermined time period. This causes the gas flow rate in the downstream pipe section to be less than or equal to the first flow rate threshold. In this case, the number of temporary storage balls in the downstream pipe section is greater than or equal to the second ball count threshold. If the number of temporary storage balls in the downstream pipe section is greater than or equal to the number of temporary storage balls in the downstream pipe section during normal operation, the number of temporary storage balls in the downstream pipe section is normal.

[0074] When the gas flow rate in the downstream pipe section within a predetermined time period is less than or equal to the second flow rate threshold (the second flow rate threshold is less than the first flow rate threshold), it indicates that the number of temporary storage balls in the downstream pipe section is greater than the number of temporary storage balls when the flow rate in the downstream pipe section is less than or equal to the first flow rate threshold. At this time, a buildup of temporary storage balls has occurred in the downstream pipe section, that is, a lifting fault has occurred in the downstream pipe section, and the lifting fault needs to be resolved.

[0075] In the above embodiments, the second ball count threshold can be 3, 4, 5, 6, 7, 8, or 9, or other values. This embodiment does not limit the second ball count threshold. The first flow rate threshold is 15 cubic meters per hour, and the second flow rate threshold is 10 cubic meters per hour. The first and second flow rate thresholds can also be other values. This embodiment does not limit the first and second flow rate thresholds.

[0076] In some embodiments of the present invention, the step of determining a flow restrictor fault further includes:

[0077] S601: Control the rotor of the flow restrictor to rotate in the reverse direction;

[0078] S602: Perform the initialization settings for the current blocker;

[0079] S603: Based on the normal initialization of the current blocker, obtain the operating status of the current blocker;

[0080] S604: Based on the normal operating status of the flow restrictor, it is determined that the fault of the flow restrictor has been resolved.

[0081] Once a malfunction is detected in the flow arrester, it is necessary to address the fault as quickly as possible to restore the high-temperature reactor fuel loading and unloading system to normal operation. Specifically, this is achieved by manually pressing the small-torque reverse rotation button or by controlling the small-torque reverse rotation via a program. This allows the flow arrester to control the rotor's reverse rotation with a small torque, dislodging the fuel balls stuck between the rotor and the outer casing. After the rotor reverse rotation is completed, the flow arrester is initialized. If the initialization is successful, the rotor has been reset. Further, the operating status of the flow arrester is monitored. If the rotor speed is greater than or equal to the speed threshold, the rotor is operating normally, indicating that the flow arrester is functioning correctly. At this point, the fault in the flow arrester is considered resolved.

[0082] In some embodiments of the present invention, after performing the initialization settings of the current blocker, the method further includes:

[0083] S605: Execute the reverse purging operation of the current blocker according to the initialization abnormality of the current blocker;

[0084] S606: Obtain the operating status of the flow restrictor;

[0085] S607: Based on the normal operating status of the flow restrictor, it is determined that the fault of the flow restrictor has been resolved.

[0086] After the rotor reverses, the flow obstructor is initialized. If initialization fails, it indicates the rotor has not returned to its initial position, and the flow obstructor remains faulty. Then, a reverse purging operation is performed. Specifically, the flow obstructor's casing has purging holes and purging channels. Once the system detects the rotor's stuck position and normal operating direction, external purging gas is introduced into the purging channel via an external air source. The purging gas travels through the purging channel to the purging hole, which faces the bottom of the stuck fuel ball. High-pressure external gas is used to purge the stuck fuel ball, and depending on its current location, the stuck fuel ball is blown to the upstream or downstream pipeline to release the blockage. After reverse purging, the flow obstructor is restarted. The flow obstructor's operating status is then monitored. If the rotor speed is greater than or equal to the speed threshold, the rotor is operating normally, meaning the flow obstructor is functioning correctly. At this point, the flow obstructor's fault is considered resolved.

[0087] In some embodiments of the present invention, determining that the fault of the current blocker has been cleared further includes:

[0088] S700: Manually empty the temporary ball in the connecting pipe section.

[0089] Once the flow restrictor malfunction is resolved, the temporary balls in both the upstream and downstream pipe sections need to be manually emptied to ensure that there are no temporary balls remaining in either section. Specifically, the flow restrictor is manually controlled to transfer the temporary balls from the upstream section to the downstream section, and then gas is used to transfer the temporary balls from the downstream section to the next device.

[0090] The operation process of the flow obstruction fault identification and handling method of the high-temperature reactor fuel loading and unloading system of the present invention is as follows:

[0091] First, obtain the operating status of the flow restrictor and the number of temporary balls in the connecting pipe section. Based on the abnormal operating status of the flow restrictor and the abnormal number of temporary balls in the connecting pipe section, determine the flow restrictor fault.

[0092] Second, put the flow stopper into manual control and shut down the equipment upstream of the flow stopper. Specifically, if the system is undergoing secondary fuel loading, shut down one or two fuel loading drive mechanisms; if the system is undergoing core fuel cycling, put the burnup measurement positioning distributor into manual control.

[0093] Third, obtain the gas flow rate in the downstream pipe section within a predetermined time. If the gas flow rate within the predetermined time is less than or equal to the second flow rate threshold, determine that there is a lifting fault in the downstream pipe section and resolve the lifting fault.

[0094] Fourth, based on the choke fault, perform a small torque reverse rotation of the choke rotor, then perform choke initialization, and simultaneously monitor the sound. If the initialization is normal, the choke fault is resolved; if the initialization is abnormal and there is an abnormal sound, repair is required; if the initialization is abnormal and there is no abnormal sound, continue to perform the choke fault resolution operation.

[0095] Fifth, perform reverse purging of the flow restrictor, and then check the operating status of the rotor or the counter count in the downstream pipe section. If the rotor is running normally or the counter count increases, it is determined that the flow restrictor has been cleared of the fault.

[0096] Sixth, manually empty the temporary storage balls in the upstream and downstream pipe sections.

[0097] The second invention proposes a flow obstruction fault identification and processing system for a high-temperature reactor fuel loading and unloading system. This system is used to execute the flow obstruction fault identification and processing method for a high-temperature reactor fuel loading and unloading system according to any of the above embodiments. The high-temperature reactor fuel loading and unloading system includes: a flow obstruction assembly, which includes a flow obstruction and a connecting pipe section. The connecting pipe section includes an upstream pipe section and a downstream pipe section, which are respectively connected to the flow obstruction. The system is characterized in that it includes:

[0098] The acquisition module is used to acquire the operating status of the flow restrictor and to acquire the number of temporary balls in the connecting pipe section;

[0099] The judgment module is used to determine whether the operating status of the flow restrictor is abnormal, whether the number of temporary balls in the connecting pipe section is abnormal, and to determine that the flow restrictor is faulty based on the abnormal operating status of the flow restrictor and the abnormal number of temporary balls in the connecting pipe section.

[0100] According to the high-temperature reactor fuel loading and unloading system of the present invention, the acquisition module acquires the operating status of the flow stopper and the number of temporary balls in the connecting pipe section of the flow stopper; the judgment module determines whether the operating status of the flow stopper is abnormal and whether the number of temporary balls in the connecting pipe section is abnormal; and the judgment module determines that the flow stopper is faulty based on the abnormal operating status of the flow stopper and the abnormal number of temporary balls in the connecting pipe section. The method of the embodiments of the present invention can quickly identify flow stopper faults, thereby reducing the impact of flow stopper faults on the loading and unloading efficiency of the high-temperature reactor fuel loading and unloading system.

[0101] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of this disclosure, and this disclosure is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and substance of this disclosure, and these modifications and improvements are also considered to be within the scope of protection of this disclosure.
