Description

Technical Field

[0001] The invention relates to the technical field of high temperature gas-cooled reactors, and in particular to an airflow disturbance method for automatic unloading of a pebble bed type high temperature gas-cooled reactor. Background Art

[0002] As one of the nuclear power reactor technologies, the pebble bed high temperature gas-cooled reactor usually uses spherical fuel elements and adopts the method of non-stop stacking and fuel replacement. When the reactor is in operation, the fuel cycle is continuously carried out. A certain number of new fuel elements need to be added to the pile every day, and the same number of spent fuel elements need to be unloaded from the pile. The spent fuel elements unloaded from the core are first transported to the spent fuel temporary storage device by air flow lifting. When the number of spent fuel elements in the spent fuel temporary storage device reaches the design value, the atmosphere is switched and then transported to the spent fuel storage tank by the spent fuel temporary storage device.

[0003] When the spent fuel elements unloaded from the core are transported to the spent fuel temporary storage device (this process is called primary unloading), a helium gas flow with a certain pressure and flow provided by a helium compressor is used to provide the transportation power. However, due to the layout characteristics of the transportation pipeline under current actual conditions, when the parameters such as helium pressure, helium flow, number of elements, etc. are different, or when the shapes of different spent fuel elements are different, it is common for the spent fuel elements to run slowly in the lifting pipeline, experience suspended vibration, or even fail to be lifted successfully for a long time. This will directly affect the fuel replacement speed of the core, and may further affect the reserve of the reactor core reactivity.

[0004] In the prior art, operators usually patrol the platform regularly to monitor the unloading process. When they find that there are abnormal situations such as spent fuel elements in the lifting pipeline that cannot be lifted successfully, they use manual intervention methods such as closing the lifting air supply valve to disturb the air flow to ensure the normal unloading of the spent fuel elements. However, this method requires operators to spend a lot of time and energy on monitoring and intervention, which affects the unloading speed. Summary of the invention

[0005] In view of this, the present invention provides an airflow disturbance method for automatic unloading of a pebble bed high temperature gas-cooled reactor to solve the problem in the prior art that manual monitoring and intervention in spent fuel unloading and airflow disturbance are required, resulting in an impact on the unloading speed.

[0006] In a first aspect, the present invention provides an airflow disturbance method for automatic unloading of a pebble bed type high temperature gas-cooled reactor, which is applied to an airflow disturbance system for automatic unloading of a pebble bed type high temperature gas-cooled reactor, the system comprising a unloading baffle, a counter and a solenoid valve, and the method comprises:

[0007] Setting the initial value of the parameter of the element being lifted in the unloading pipeline, the parameter of the element being lifted in the unloading pipeline is used to characterize the number of spherical elements being lifted in the primary unloading of the pebble bed high temperature gas-cooled reactor;

[0008] When the control system detects the action of the discharge blocker, the parameters of the components being lifted in the discharge pipeline are updated;

[0009] receiving a counting result of a counter of a parameter of a component being lifted in the discharge pipeline, and updating the parameter of the component being lifted in the discharge pipeline again according to the counting result of the parameter of the component being lifted in the discharge pipeline;

[0010] The compressor or valve is automatically controlled according to the magnitude relationship between the updated parameter of the component being increased in the discharge pipeline and the initial value of the parameter of the component being increased in the discharge pipeline to perform air flow disturbance.

[0011] The present invention sets the initial value of the parameter of the element being lifted in the unloading pipeline, updates the parameter of the element being lifted in the unloading pipeline when the action of the baffle is detected, so as to judge the number of balls in the lifting pipeline, updates the parameter of the element being lifted in the unloading pipeline again according to the counting result of the counter, compares the updated parameter of the element being lifted in the unloading pipeline with the initial value of the parameter of the element being lifted in the unloading pipeline, so as to judge whether the unloading spherical element is lifted successfully, and automatically controls the solenoid valve according to the comparison result to perform airflow disturbance, so as to save the step of the operator manually monitoring and intervening in the spent fuel unloading to perform airflow disturbance, thereby realizing automatic airflow disturbance and improving the unloading speed.

[0012] In an optional embodiment, when the control system detects that the discharge blocker is actuated, the parameters of the element being lifted in the discharge pipeline are updated, including:

[0013] Receive the action signal fed back by the unloading damper, and judge whether the unloading damper is in action according to the position signal of the damper;

[0014] If the unloading flow control device is activated, the parameter of the component being lifted in the unloading pipeline will be increased by one.

[0015] The present invention receives the position signal fed back by the baffle to determine whether the unloading baffle is in action, and when the unloading baffle is in action, adds one to the parameter of the element being lifted in the unloading pipeline, and updates the parameter of the element being lifted in the unloading pipeline to indicate whether the baffle has transported the spherical fuel element, thereby realizing automatic monitoring of the unloading process and reducing the monitoring pressure of the operator.

[0016] In an optional embodiment, the counter includes a first counter, a second counter and a third counter, receives the counting results of the counters, and updates the parameters of the element being lifted in the discharge pipeline again according to the counting results, including:

[0017] Receiving counting results of the first counter, the second counter and the third counter respectively;

[0018] If at least two of the first counter, the second counter and the third counter are counting forward and the first counter is not counting backward, the parameter of the element being lifted in the discharge pipeline is reduced by one.

[0019] The present invention receives the counting results of the first counter, the second counter and the third counter respectively, and determines whether the unloading spherical element is lifted successfully according to the counting results of each counter. When at least two counters among the first counter, the second counter and the third counter are counting forward and the first counter is not counting reversely, the initial value of the parameter of the element being lifted in the unloading pipeline is reduced by one, and the parameter of the element being lifted in the unloading pipeline is updated, thereby realizing automatic monitoring of whether the unloading spherical element is lifted successfully and reducing the monitoring pressure of the operator.

[0020] In an optional embodiment, the solenoid valve is automatically controlled to disturb the airflow according to the magnitude relationship between the updated parameter of the component being raised in the discharge pipeline and the initial value of the parameter of the component being raised in the discharge pipeline, including:

[0021] If the updated parameter of the component being raised in the discharge pipeline is greater than the initial value of the parameter of the component being raised in the discharge pipeline, and the duration reaches a first preset duration, the solenoid valve is automatically adjusted to disturb the airflow.

[0022] According to the present invention, after the parameters of the component being lifted in the unloading pipeline are updated, when the parameters of the component being lifted in the unloading pipeline after the update are greater than the initial values ​​of the parameters of the component being lifted in the unloading pipeline and the duration reaches a first preset time, the lifting of the unloading spherical component fails, and the airflow is disturbed by automatically adjusting the solenoid valve of the compressor, thereby eliminating the step of the operator manually closing the lifting air supply valve to disturb the airflow, thereby increasing the unloading speed.

[0023] In an optional embodiment, the electromagnetic valve is automatically controlled to perform airflow disturbance according to the magnitude relationship between the updated parameter of the component being raised in the discharge pipeline and the initial value of the parameter of the component being raised in the discharge pipeline, and the method further includes:

[0024] If the updated parameter of the component being promoted in the unloading pipeline is equal to the initial value of the parameter of the component being promoted in the unloading pipeline, the unloading continues.

[0025] When the parameter of the component being lifted in the updated unloading pipeline is equal to the initial value of the parameter of the component being lifted in the unloading pipeline, that is, the lifting of the unloading spherical component is successful, the unloading is continued to lift the next unloading spherical component, thereby reducing the manual intervention of the operator and improving the unloading speed.

[0026] In an optional embodiment, after the solenoid valve is automatically controlled to actuate and the airflow is disturbed, the method further comprises:

[0027] When it is detected that the opening time of the solenoid valve reaches the second preset time, it is determined again whether the parameter of the component being lifted in the current discharge pipeline is equal to the initial value of the parameter of the component being lifted in the discharge pipeline;

[0028] If the time during which the parameter of the component being raised in the current unloading pipeline is greater than the initial value of the parameter of the component being raised in the unloading pipeline reaches a second preset time length, an alarm signal is generated.

[0029] The present invention detects the size between the parameter of the component being lifted in the current unloading pipeline and the initial value of the parameter of the component being lifted in the unloading pipeline, and again determines whether the parameter of the component being lifted in the current unloading pipeline is equal to the initial value of the parameter of the component being lifted in the unloading pipeline, so as to determine whether the unloading spherical component is lifted successfully after the first airflow disturbance, and generates an alarm signal when the parameter of the component being lifted in the current unloading pipeline is still greater than the initial value of the parameter of the component being lifted in the unloading pipeline and the duration reaches a certain value, so as to remind the operator to perform manual intervention in time to avoid the failure of lifting the unloading spherical component and the damage caused by long-term vibration.

[0030] In a second aspect, the present invention provides an air flow disturbance device for automatic unloading of a pebble bed type high temperature gas-cooled reactor, the device comprising:

[0031] A setting module, used to set the initial value of the parameter of the element being lifted in the unloading pipeline, the parameter of the element being lifted in the unloading pipeline is used to characterize the number of spherical elements being lifted in the primary unloading pipeline of the pebble bed type high temperature gas-cooled reactor;

[0032] A first updating module is used to update the parameters of the components being lifted in the discharge pipeline when the control system detects the action of the discharge blocker;

[0033] The second updating module is used to receive the counting result of the counter and update the parameters of the component being lifted in the discharge pipeline again according to the counting result;

[0034] The control module is used to automatically control the action of the solenoid valve to disturb the airflow according to the size relationship between the updated parameter of the component being lifted in the discharge pipeline and the initial value of the parameter of the component being lifted in the discharge pipeline.

[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0046] According to an embodiment of the present invention, an air flow disturbance system for automatic unloading of a pebble bed high temperature gas-cooled reactor is provided. Figure 1 As shown, the system includes an electric regulating valve 1, a solenoid valve 2, a launcher 3, a discharge baffle 4, a reducer 5, a steering gear 6, a first electric valve 7, a second electric valve 8, a third electric valve 9, a fourth electric valve 10, a first temporary storage device 11, a second temporary storage device 12, a first counter 13, a second counter 14, a third counter 15, a fourth counter 16, a fifth counter 17, a sixth counter 18, a seventh counter 19 and a compressor 20.

[0047] The process of lifting the spent fuel elements or graphite balls (hereinafter collectively referred to as spherical elements) discharged from the core of the pebble bed high temperature gas-cooled reactor to the temporary storage device for unloading is as follows:

[0048] The spent fuel elements or graphite balls discharged from the core first reach the unloading baffle 4. If there is no element being lifted in the lifting pipeline downstream of the unloading baffle 4, the unloading baffle 4 will be activated once. After an element upstream of the unloading baffle 4 is transported to the downstream and returned to the initial position, the element reaches the launcher 3 by gravity. The lifting airflow from the compressor 20 lifts the element in the launcher 3 and passes through the first counter 13, the second counter 14, the third counter 15, and the fourth counter 16 in sequence. The first counter 13, the second counter 14, and the third counter 15 are located at the top of the lifting pipeline, and the first counter 13 is a bidirectional counter. After reaching the top, the element enters the reducer 5 for deceleration to prevent damage caused by excessive speed, and the lifting airflow and the element are separated from the ball gas in the reducer 5. The airflow flows back to the inlet of the compressor 20, and the spherical element continues to run to the diverter 6, and then enters the first temporary storage device 11 or the second temporary storage device 12 of the unloading by gravity.

[0049] At present, from the actual operation experience, after the unloading baffle 4 transports the components to the lifting pipeline, there is a high probability that the components will be suspended and vibrated in the lifting pipeline, and even cannot be lifted successfully for a long time. Since the lifting can only be done one by one, the unloading baffle 4 cannot be activated again to release the balls, thereby affecting the material replacement speed. The long-term suspension and vibration of the components may also cause damage to them, requiring manual intervention by the operator, which greatly increases the monitoring pressure of the operator. In order to solve the above problems, an embodiment of the present invention provides an airflow disturbance method for automatic unloading of a pebble bed high temperature gas-cooled reactor.

[0050] According to an embodiment of the present invention, an embodiment of an airflow disturbance method for automated unloading of a pebble bed type high temperature gas-cooled reactor is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that shown here.

[0051] In this embodiment, a method for air flow disturbance for automatic unloading of a pebble bed high temperature gas-cooled reactor is provided. Figure 2 is a flow chart of an airflow disturbance method for automatic unloading of a pebble bed type high temperature gas-cooled reactor according to an embodiment of the present invention, such as Figure 2 As shown, the process includes the following steps:

[0052] Step S201, setting the initial value of the parameter of the component being lifted in the discharge pipeline.

[0053] In the embodiment of the present invention, the parameter of the element being lifted in the discharge pipeline is used to characterize the number of spherical elements being lifted in the primary discharge pipeline of the pebble bed type high temperature gas-cooled reactor. The parameter N of the element being lifted in the discharge pipeline is set in the DCS (Distributed Control System) system, and the initial value of the parameter N of the element being lifted in the discharge pipeline is set to 0.

[0054] Step S202, when the control system detects that the unloading flow control device is actuated, the parameters of the components being lifted in the unloading pipeline are updated.

[0055] In the embodiment of the present invention, when the component falls into the unloading blocker, the DCS controls the unloading blocker to operate, and after the unloading blocker operates, its operation signal is fed back to the DCS. When the DCS detects the operation of the unloading blocker, the parameter N of the component being lifted in the unloading pipeline is increased by one, indicating that a component has passed.

[0056] Step S203, receiving the counting result of the counter, and updating the parameters of the component being lifted in the discharge pipeline again according to the counting result.

[0057] In the embodiment of the present invention, the component reaches the launcher by gravity, and the lifting airflow lifts the component in the launcher, passing through the first counter, the second counter, the third counter and the fourth counter in sequence. Since the first counter, the second counter and the third counter are located at the top of the lifting pipeline, it is necessary to monitor the counting results of the first counter, the second counter and the third counter, and update the parameter N of the component being lifted in the discharge pipeline again according to the counting results to determine whether the component is lifted successfully.

[0058] Step S204, automatically controlling the solenoid valve to disturb the airflow according to the magnitude relationship between the updated parameter of the component being lifted in the discharge pipeline and the initial value of the parameter of the component being lifted in the discharge pipeline.

[0059] In an embodiment of the present invention, the updated parameters of the element being lifted in the discharge pipeline represent the number of balls being lifted in the lifting pipeline. According to the relationship between the updated parameters of the element being lifted in the discharge pipeline and the initial values ​​of the parameters of the element being lifted in the discharge pipeline, it is determined whether there are elements being lifted simultaneously in the lifting pipeline. In order to avoid lifting failure caused by the simultaneous lifting of two elements, it is necessary to control the action of the solenoid valve of the compressor to disturb the airflow according to the relationship between the updated parameters of the element being lifted in the discharge pipeline and the initial values ​​of the parameters of the element being lifted in the discharge pipeline.

[0060] The present embodiment provides an airflow disturbance method for automatic unloading of a pebble bed type high temperature gas-cooled reactor. By setting the initial value of the parameter of the element being lifted in the unloading pipeline, when the action of the baffle is detected, the parameter of the element being lifted in the unloading pipeline is updated to determine the number of balls in the lifting pipeline, and the parameter of the element being lifted in the unloading pipeline is updated again according to the counting result of the counter, so as to compare the updated parameter of the element being lifted in the unloading pipeline with the initial value of the parameter of the element being lifted in the unloading pipeline, so as to determine whether the unloading spherical element is lifted successfully, and automatically control the solenoid valve according to the comparison result to perform airflow disturbance, so as to save the operator from manually monitoring and intervening in the spent fuel unloading to perform airflow disturbance, thereby realizing automatic interference with the lifting airflow and improving the unloading speed.

[0061] In this embodiment, a method for airflow disturbance for automatic unloading of a pebble bed high temperature gas-cooled reactor is provided, and the process includes the following steps:

[0062] Step S301, setting the initial value of the parameter of the component being lifted in the discharge pipeline.

[0063] For details, please see Figure 2 Step S201 of the illustrated embodiment will not be described in detail here.

[0064] Step S302, when the control system detects that the unloading flow control device is actuated, the parameters of the components being lifted in the unloading pipeline are updated.

[0065] Specifically, the above step S302 includes:

[0066] Step S3021, receiving the action signal fed back by the unloading flow blocker, and judging whether the unloading flow blocker is actuated according to the action signal.

[0067] Step S3022, if the unloading flow control device is actuated, the parameter of the component being lifted in the unloading pipeline is increased by one.

[0068] In the embodiment of the present invention, an action signal fed back by the unloading baffle is received, and the signal indicates whether the unloading baffle is in action. When the unloading spherical element unloaded from the core reaches the baffle, the DCS controls the baffle to act, and the parameter N of the element being lifted in the unloading pipeline is increased by one, which is determined as the updated parameter of the element being lifted in the unloading pipeline.

[0069] By receiving the position signal fed back by the choke, it is determined whether the choke is actuated. When the choke is actuated, the value of the parameter of the component being lifted in the discharge pipeline is increased by one, and the parameter of the component being lifted in the discharge pipeline is updated, thereby realizing automatic monitoring of the discharge process and reducing the pressure on the operator to monitor the panel.

[0070] Step S303, receiving the counting result of the counter, and updating the parameters of the component being lifted in the discharge pipeline again according to the counting result.

[0071] Specifically, the above step S303 includes:

[0072] Step S3031, receiving counting results of the first counter, the second counter and the third counter respectively.

[0073] Step S3032: if at least two of the first counter, the second counter and the third counter are counting forward and the first counter is not counting backward, then the parameter of the element being lifted in the discharge pipeline is reduced by one.

[0074] In an embodiment of the present invention, after the component reaches the transmitter, it passes through the first counter, the second counter and the third counter in sequence. If at least two of the first counter, the second counter and the third counter are counting forward and the first counter is not counting reversely, the parameter N of the component being lifted in the unloading pipeline is reduced by one, and is determined as the updated parameter of the component being lifted in the unloading pipeline.

[0075] By respectively receiving the counting results of the first counter, the second counter and the third counter, it is determined whether the unloading spherical element is lifted successfully according to the counting results of each counter, and when at least two of the first counter, the second counter and the third counter are counting forward and the first counter is not counting reversely, the initial value of the parameter of the element being lifted in the unloading pipeline is reduced by one, and the parameter of the element being lifted in the unloading pipeline is updated, thereby realizing automatic monitoring of whether the unloading spherical element is lifted successfully and reducing the monitoring pressure of the operator.

[0076] Step S304, automatically controlling the action of the solenoid valve to disturb the airflow according to the magnitude relationship between the updated parameter of the component being lifted in the discharge pipeline and the initial value of the parameter of the component being lifted in the discharge pipeline.

[0077] Specifically, the above step S304 includes:

[0078] Step S3041, if the updated parameter of the component being promoted in the discharge pipeline is greater than the initial value of the parameter of the component being promoted in the discharge pipeline, and the duration reaches a first preset duration, the solenoid valve of the compressor is automatically adjusted to perform airflow disturbance.

[0079] In an embodiment of the present invention, if the updated parameter N of the element being increased in the discharge pipeline is greater than the initial value 0 of the parameter of the element being increased in the discharge pipeline, that is, N≥1, and the duration reaches 1 minute, N still does not decrease, and the baffle no longer releases the ball downstream, the solenoid valve of the compressor is automatically closed, and the solenoid valve is automatically opened after 3s (seconds) to disturb the airflow.

[0080] After the parameters of the component being lifted in the unloading pipeline are updated, if the updated parameters of the component being lifted in the unloading pipeline are greater than the initial values ​​of the parameters of the component being lifted in the unloading pipeline and the duration reaches a first preset duration, the lifting of the unloading spherical component fails, and the airflow is disturbed by automatically adjusting the solenoid valve of the compressor, eliminating the step of the operator manually closing the lifting air supply valve to disturb the airflow, thereby increasing the unloading speed.

[0081] Step S3042: If the updated parameter of the component being lifted in the unloading pipeline is equal to the initial value of the parameter of the component being lifted in the unloading pipeline, the unloading is continued.

[0082] In the embodiment of the present invention, if the updated parameter N of the element being lifted in the discharge pipeline is equal to the initial value 0 of the parameter N of the element being lifted in the discharge pipeline, the baffle can continue to operate, automatically release the ball into the lifting pipeline, and continue to unload.

[0083] It should be noted that if the parameter N of the element being lifted in the updated unloading pipeline is reduced from 1 to 0 within one minute, there is no need to interfere with the airflow and the unloading can continue.

[0084] When the parameters of the component being lifted in the updated unloading pipeline are equal to the initial values ​​of the parameters of the component being lifted in the unloading pipeline, that is, the lifting of the unloading spherical component is successful, the unloading will continue to lift the next unloading spherical component, reducing the operator's manual intervention and increasing the unloading speed.

[0085] Step S3043, when the opening time of the solenoid valve reaches the second preset time, it is determined again whether the parameter of the component being lifted in the current discharge pipeline is equal to the initial value of the parameter of the component being lifted in the discharge pipeline.

[0086] Step S3044: if the parameter of the component being lifted in the current unloading pipeline is still greater than the initial value of the parameter of the component being lifted in the unloading pipeline, an alarm signal is generated.

[0087] In an embodiment of the present invention, if it is detected that the time after the solenoid valve is reopened (closed and then opened) reaches 60s, the parameter of the component being lifted in the current discharge pipeline is monitored, and it is judged again whether the parameter of the component being lifted in the current discharge pipeline is equal to the initial value of the parameter of the component being lifted in the discharge pipeline, so as to judge whether the parameter N of the component being lifted in the discharge pipeline is reduced. If the parameter N of the component being lifted in the discharge pipeline is 0, it means that the lifting is successful, and the baffle continues to release the ball into the lifting pipeline to lift the next component. If the parameter N of the component being lifted in the discharge pipeline remains unchanged after the solenoid valve is opened for 60s, that is, it is still greater than the initial value of the parameter of the component being lifted in the discharge pipeline, the solenoid valve is closed again, and the solenoid valve is automatically opened after 5s. After the solenoid valve is actuated twice, the parameter N of the component being lifted in the discharge pipeline still does not decrease, and the duration exceeds 3 minutes, an alarm signal is generated, and an alarm is issued to the operator, and the operator intervenes manually.

[0088] The airflow disturbance method for automatic unloading of a pebble bed type high temperature gas-cooled reactor provided in this embodiment detects the opening time of the solenoid valve, and again determines whether the parameters of the component being lifted in the current unloading pipeline are equal to the initial values ​​of the parameters of the component being lifted in the unloading pipeline, so as to determine whether the unloading spherical component is successfully lifted after the first airflow disturbance, and generates an alarm signal when the parameters of the component being lifted in the current unloading pipeline are still greater than the initial values ​​of the parameters of the component being lifted in the unloading pipeline, so as to remind the operator to perform manual intervention in time to avoid failure in lifting the unloading spherical component and damage caused by long-term vibration.

[0103] In some optional implementations, the control module 304 further includes:
