Description

Technical Field

[0001] The present invention relates to the technical field of warm gas-cooled reactor control rod fault processing, and in particular to a high temperature gas-cooled reactor control rod fault processing method and system. Background Art

[0002] The demonstration project of the high-temperature gas-cooled reactor nuclear power plant is the world's first reactor, and each reactor is equipped with 24 control rods, including 6 safety rods, 6 regulating rods, and 12 compensation rods. When a control rod is stuck during an emergency shutdown, the safety rod has left the upper limit position. If the regulating rod is stuck, manual operation cannot be performed because the conditions for moving the rod are not met (the safety rod is at the upper limit position and the power control is ready).

[0003] Currently, a fault handling module is set in the control system of the control rod. When the fault handling button is activated, the rod with the current fault can be operated after the local driver is powered on and the protection signal is restored. The rod moving limit is 200mm (this limit is consumed by lowering the rod). If multiple control rods are involved, the fault handling button needs to be withdrawn and re-activated each time. If the withdrawal operation is not performed, the operation limit of the next control rod will become smaller or it will be impossible to operate. Summary of the invention

[0004] In view of this, the present invention provides a method and system for handling control rod failures of a high temperature gas-cooled reactor to solve the problems of improper operation, confusion of limit values ​​or inability to operate the control rods.

[0005] In a first aspect, the present invention provides a method for handling a control rod failure of a high temperature gas-cooled reactor, the method comprising:

[0006] Set the maximum limit value of each control rod and use it as the initial current maximum limit value;

[0007] After the faulty control rod triggers the fault processing signal, the current rod lifting limit of the current faulty control rod is set;

[0008] The rod lifting action is performed based on the constraint conditions determined by the current maximum rod lifting limit value, and the current maximum rod lifting limit value is updated; if the control rod is switched back to the faulty control rod that has been operated, the current maximum rod lifting limit value updated after the rod lifting action is used as the current maximum rod lifting limit value, and the set maximum rod lifting limit value will not be restored.

[0009] The method for handling control rod faults of a high-temperature gas-cooled reactor provided in an embodiment of the present invention enables the operator to press the fault handling button only once when handling a single control rod fault, thereby strictly ensuring that the control rod lifting limit is the set maximum rod lifting limit value, without being restricted by lowering or switching control rods, thereby avoiding the situation where the rod lifting exceeds the limit or cannot be operated due to operating errors.

[0010] In an optional implementation manner, the maximum rod lifting limit value of each control rod is set as the initial current maximum rod lifting limit value, including:

[0011] Set the maximum limit value of each control rod as the initial control rod limit storage value, recorded as A value;

[0012] The initial control rod lifting limit storage value is assigned to the current maximum control rod lifting limit value, which is recorded as B value.

[0013] In the embodiment of the present invention, the control rod lifting limit storage value is used as an intermediate storage amount to update the current maximum rod lifting limit value according to the faulty control rod movement situation, thereby preventing limit value confusion.

[0014] In an optional implementation manner, the current rod lifting limit value of the currently faulty control rod is set, which is recorded as C value;

[0015] The step of performing a rod lifting action based on the constraint condition determined by the current maximum rod lifting limit value and updating the current maximum rod lifting limit value includes:

[0016] Determine whether the C value is between 0 and B value;

[0017] If yes, then raise the bar according to the C value; if no, assign the B value to the C value, and raise the bar according to the C value;

[0018] After the control rod lifting action is completed, BC is assigned to the B value, and the B value is assigned to the control rod lifting limit storage value to update the A value.

[0019] The embodiment of the present invention sets a clear upper limit for the rod lifting action through the current maximum rod lifting limit value, which can effectively prevent the control rod from being over-lifted and avoid the reactor's unexpected critical power increase, thereby reducing the risk of nuclear accidents. By strictly complying with this constraint, it can be ensured that the reactor always operates within a safe range to protect the safety of equipment and personnel.

[0020] In an optional embodiment, the value of B is kept unchanged in other situations where the control rod is not lifted during failure processing.

[0021] In the embodiment of the present invention, when the control rod is not in a fault state, the current maximum rod lifting limit value does not take effect. When performing fault handling, the operator does not need to frequently pay attention to and adjust the rod lifting limit value, and only needs to intervene when the control rod fails or in specific circumstances, which reduces the complexity of operation, improves work efficiency, and also reduces the probability of human error. At the same time, during the operator handover process, the continuity and stability of the operation can also be ensured, avoiding confusion and misunderstanding caused by changes in the rod lifting limit value.

[0022] In an optional implementation, the method further includes: displaying the current maximum rod lifting limit of each control rod based on a human-computer interaction interface.

[0023] The embodiment of the present invention adds a numerical value B display in the human-computer interaction interface, which makes it convenient for the operator to understand the current maximum rod lifting limit of each control rod in real time. The operator can operate the control rods more accurately and input the current rod lifting limit C value more accurately to avoid over-lifting or under-lifting of the rods, which is conducive to rapid fault handling, thereby improving the operating efficiency and stability of the reactor.

[0024] In an optional embodiment, the method further includes: when the fault handling exit signal is triggered and re-engaged, the current maximum rod lifting limit value of all control rods is restored to the set maximum rod lifting limit value.

[0025] The embodiment of the present invention can provide a clear operating standard for the operator by restoring the value A after exiting the fault processing and re-entering. When the fault processing is completed, the value is restored to make the operation process more standardized, reduce the operation complexity and uncertainty caused by different lifting limit values, and reduce the risk of human operation errors.

[0026] In a second aspect, the present invention provides a high temperature gas-cooled reactor control rod fault processing system, the system comprising:

[0027] The maximum limit setting module is used to set the maximum limit value of each control rod and use it as the initial current maximum limit value of the control rod;

[0028] A current rod lifting limit setting module is used to set the current rod lifting limit of the current faulty control rod after the fault processing signal is triggered based on the faulty control rod;

[0029] The maximum rod lifting limit value updating module is used to perform the rod lifting action based on the constraint conditions determined by the current maximum rod lifting limit value, and update the current maximum rod lifting limit value; if the control rod is switched back to the faulty control rod that has been operated, the current maximum rod lifting limit value updated after the rod lifting action will be used as the current maximum rod lifting limit value, and will not be restored to the set maximum rod lifting limit value.

[0030] In a third aspect, the present invention provides a computer device, comprising: a memory and a processor, the memory and the processor being communicatively connected to each other, the memory storing computer instructions, and the processor executing the high-temperature gas-cooled reactor control rod failure handling method of the first aspect or any corresponding embodiment thereof by executing the computer instructions.

[0038] 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.

[0039] At present, a fault handling module is set in the control system of the control rod. When the fault handling button is activated, the rod with the current fault can be operated after the local driver is powered on and the protection signal is restored. The rod moving limit is 200mm (this limit is consumed by lowering the rod). If multiple control rods are involved, the fault handling button needs to be withdrawn and re-activated each time. If the withdrawal operation is not performed, the next control rod operation limit will become smaller or the operation cannot be performed.

[0040] In this embodiment, a method for handling control rod failures of a high temperature gas-cooled reactor is provided, which optimizes the fault handling logic in the current control rod control system. When the operator performs a single control rod failure handling, he only needs to press the fault handling button once, so as to strictly set the control rod lifting limit value to the set maximum rod lifting limit value. 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 the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than that here.

[0041] Figure 1 is a flow chart of a method for handling a control rod failure of a high temperature gas-cooled reactor according to an embodiment of the present invention, which can be used in the above-mentioned computer system, such as Figure 1 As shown, the process includes the following steps:

[0042] Step S101, setting the maximum rod lifting limit value of each control rod and using it as the initial current maximum rod lifting limit value.

[0043] Specifically, the maximum rod lifting limit value of each control rod is generally set to 200mm, which can ensure the stable operation of the high temperature gas-cooled reactor. In the embodiment of the present invention, the maximum rod lifting limit value of each control rod is set as the initial control rod lifting limit value storage value, which is stored in the 24 control rod limit value storage modules and recorded as value A; the initial control rod lifting limit value storage value is assigned to the current maximum rod lifting limit value, which is recorded as value B. In the embodiment of the present invention, the control rod lifting limit value storage value is used as an intermediate storage amount to update the current maximum rod lifting limit value according to the condition of the faulty control rod movement to prevent limit confusion.

[0044] Step S102, after the faulty control rod triggers a fault processing signal, a current rod lifting limit value of the current faulty control rod is set.

[0045] Specifically, after the operator triggers the fault handling signal by pressing the fault handling button according to the faulty control rod, the operator sets the current rod lifting limit value of the current faulty control rod through the human-computer interaction interface, which is recorded as C value.

[0046] Step S103, performing a rod lifting action based on the constraint conditions determined by the current maximum rod lifting limit value, and updating the current maximum rod lifting limit value; if the control rod is switched back to the faulty control rod that has been operated, the current maximum rod lifting limit value updated after the rod lifting action is used as the current maximum rod lifting limit value, and the set maximum rod lifting limit value is not restored.

[0047] Specifically, after obtaining the current rod lifting limit set by the operator for the faulty control rod, determine whether the C value is between 0 and B; if so, lift the rod according to the C value; if not, assign the B value to the C value, and lift the rod according to the C value; after the control rod lifting action is completed, assign BC to the B value, and assign the B value to the control rod lifting limit storage value to update the A value.

[0048] The embodiment of the present invention sets a clear upper limit for the rod lifting action through the current maximum rod lifting limit value, which can effectively prevent the control rod from being over-lifted and avoid the reactor's unexpected critical power increase, thereby reducing the risk of nuclear accidents. By strictly complying with this constraint, it can be ensured that the reactor always operates within a safe range to protect the safety of equipment and personnel.

[0049] In the embodiment of the present invention, the B value is kept unchanged in other situations where the control rod is not being lifted during fault handling, thereby realizing the holding function. In the embodiment of the present invention, when the control rod is not in a faulty state, the current maximum limit value for lifting the rod does not take effect. When performing fault handling, the operator does not need to frequently pay attention to and adjust the limit value for lifting the rod, but only needs to intervene when the control rod fails or in specific circumstances, thereby reducing the complexity of the operation, improving work efficiency, and also reducing the probability of human error. At the same time, during the operator handover process, the continuity and stability of the operation can also be ensured, avoiding confusion and misunderstanding caused by changes in the limit value for lifting the rod.

[0050] In the embodiment of the present invention, when the signal for exiting the fault processing is triggered, the current maximum limit value of the control rods is restored to the set maximum limit value, that is, after the reset, the current maximum limit value of the control rods is restored to the value A. Restoring to the value A after exiting the fault processing can provide a clear operating standard for the operator. When the fault processing is completed, the value is restored to make the operating process more standardized, reduce the operational complexity and uncertainty caused by different limit values ​​of the control rods, and reduce the risk of human operation errors.

[0051] In one embodiment, Figure 2-Figure 5 The logic diagram of the control rod fault processing limit algorithm is shown in Figure 2. Taking a control rod as an example, the A value is the storage value of the control rod lifting limit. If the initial lifting limit of the control rod is 200mm (the A value is initially assigned to 200mm), Figure 2 As shown in the figure, after the faulty control rod is processed and put into operation, the operator sets the current lifting limit of the control rod to 50mm (C value) in the human-machine interface. The control system lifts the control rod by 50mm. After the control rod is lifted, the current maximum lifting limit B value is (200mm-50mm). Figure 3As shown, the B value is assigned to the A value, and the 24 control rod limit storage modules update the storage value to 150mm. When the control rod is switched back to the control rod, the value A will be used as the new maximum rod lifting limit value.

[0052] If control stick switching is not performed, Figure 4 As shown, it is determined whether the C value is within the range of 0 to B value, and the rod can be raised according to the latest maximum rod lifting limit. If the control rod is switched, the new control rod value A is selected through the 24 control rod limit storage modules after the switch, and it is assigned to the value B as the upper limit of the new control rod moving limit C.

[0053] like Figure 5 As shown, when the fault handling button is activated on the human-machine interface, value A is assigned to value B after the stick is selected, and value B is assigned to itself at other times to achieve the hold function.

[0054] The embodiment of the present invention adds a numerical value B display in the human-computer interaction interface, and switches the display according to the rod selection after the rod is selected, so that the operator can understand the current maximum rod lifting limit of each control rod in real time. The operator can operate the control rod more accurately and input the current rod lifting limit C value more accurately to avoid over-lifting or under-lifting of the rod, which is conducive to rapid fault handling, thereby improving the operating efficiency and stability of the reactor.

[0055] In an optional embodiment, the method further includes: when the fault handling exit signal is triggered and re-engaged, the current maximum rod lifting limit value of all control rods is restored to the set maximum rod lifting limit value. In the embodiment of the present invention, restoring to the A value after exiting the fault handling and re-engaging can provide the operator with a clear operating standard. When the fault handling is completed and restored to this value, the operating process is more standardized, the operational complexity and uncertainty caused by different rod lifting limit values ​​are reduced, and the risk of human operational errors is reduced.

[0056] The method for handling control rod faults of a high-temperature gas-cooled reactor provided in an embodiment of the present invention optimizes the fault handling logic in the existing control rod control system and displays the current maximum rod lifting limit of each control rod on a human-computer interaction interface, thereby avoiding the situation where the rod lifting exceeds the limit or cannot be operated without exceeding the limit due to operational errors, so that the operator can more clearly understand the operable range and restriction conditions of the control rod, reduce hesitation and misjudgment caused by uncertain factors, help improve operational efficiency, shorten operation time, and enable the system to resume normal operation more quickly.

[0069] After the control rod lifting action is completed, BC is assigned to the B value, and the B value is assigned to the control rod lifting limit storage value to update the A value.
