[0068] Figure 1 is a flow chart of the control method of the reactor provided in the embodiment of the present application, please refer to Figure 1 The control method of the reactor provided in the embodiment of the present application may include but is not limited to steps S101 to S103.

[0069] Step S101, obtaining the operation mode of the reactor.

[0070] In this step, the operating mode of the reactor is identified through pre-set sensors and the reactor monitoring system. The operating modes of the reactor include but are not limited to cold shutdown mode, hot shutdown mode, emergency shutdown, during reactor refueling overhaul, triggered downlink isolation conditions, during reactor loading, primary water filling mode, primary queuing mode, etc.

[0071] Step S102: Based on the operation mode, determine the control logic corresponding to the operation mode.

[0072] In this step, according to the operating mode of the reactor, the control functions of the required chemical and volumetric systems on the reactor and the control logic corresponding to the control functions are determined. The control functions include isolating the downward discharge path (i.e., the discharge path) of the reactor coolant, discharging the reactor coolant for operation, charging the reactor coolant for operation, and isolating the charging path (i.e., the supplementary path) of the reactor coolant; the control logic includes isolating the discharge path of the coolant of the reactor, discharging the coolant of the reactor, supplementing the coolant into the reactor, and isolating the supplementary path of the coolant of the reactor.

[0073] Exemplarily, when the reactor is in a refueling overhaul or the reactor triggers an isolation condition, in order to prevent the reactor coolant from leaking and prevent radioactive substances from entering the coolant, the chemical and volumetric system will isolate the reactor coolant, that is, isolate the reactor coolant discharge path.

[0074] Step S103: Control multiple valves in the chemical and volumetric system through the control logic to control the reactor.

[0075] In this step, the chemical and volumetric system includes a plurality of valves. According to the control logic corresponding to different operation modes of the reactor, the opening or closing of the corresponding plurality of valves in the chemical and volumetric system is controlled to complete the functions required by the reactor.

[0076] Specifically, the chemical and volumetric system includes a path for discharging reactor coolant and a path for charging reactor coolant. The downstream path includes a first containment isolation valve, a downstream orifice isolation valve and a downstream isolation valve arranged in sequence; the charging path includes a downstream isolation valve of the containment box, a second containment isolation valve, a charging isolation valve and a charging pump arranged in sequence. It should be noted that the above-mentioned valves are a general term for valves of the same type, and each type of valve includes one or more electric valves.

[0077] Exemplarily, according to the control logic, the first containment isolation valve, the downflow orifice isolation valve and the downflow isolation valve in the chemical and volume system are closed in sequence to isolate the downflow path of the reactor coolant.

[0078] Through the above steps S101 to S103, the chemical and volumetric system obtains the operating mode of the reactor, determines the control logic corresponding to the chemical and volumetric system under the operating mode based on the operating mode of the reactor, and automatically controls multiple valves in the chemical and volumetric system through the control logic to realize automated operation of charging and discharging the coolant of the reactor; in this way, the efficiency of charging and discharging the coolant of the reactor can be improved.

[0079] In some implementations, the control logic includes M execution conditions arranged in a sequential order, where M is a positive integer, such as Figure 2 As shown, in step S103, the multiple valves in the chemical and volume system are controlled by the control logic to control the reactor, which may include but is not limited to the following steps.

[0080] Step S1031: The execution condition ranked first among the M execution conditions is used as the current execution condition.

[0081] Step S1032: Generate a control signal corresponding to the current execution condition according to the current execution condition.

[0082] Step S1033: Control the valve involved in the current execution condition in the chemical and volume system according to the control signal corresponding to the current execution condition.

[0083] Step S1034: when the control of the valve involved in the current execution condition is completed, if there is a next execution condition of the current execution condition in the M execution conditions, then the next execution condition of the current execution condition is obtained.

[0084] Step S1035: take the next execution condition as the current execution condition, and jump to the step of generating a control signal corresponding to the current execution condition according to the current execution condition.

[0085] In this implementation, the control logic of the chemical and volumetric system is first determined, the control logic is pre-set according to the operation mode of the reactor, and the order of closing the control valves is set according to the actual situation.

[0086] It should be noted that the completion of the control of the valve involved in the current execution condition requires the successful control of the valve involved in the current execution condition. If the signal is only sent but not executed or the control fails, it does not belong to the completion of the control.

[0087] Specifically, each control logic controls a total of M valves arranged in sequence in the chemical and volumetric system, and the M valves correspond to M execution conditions. When the current execution condition is met, a control signal corresponding to the current execution condition is generated, and the control signal indicates whether to control the opening or closing of the valve involved in the current execution condition; when the control of the valve involved in the current execution condition is completed, the next execution condition is used as the current execution condition to repeat the above steps until the M execution conditions are completed. For example, there are three execution conditions. When the first execution condition is met, a first control signal is generated to control the valve corresponding to the first signal. When the valve corresponding to the first signal is successfully controlled, if the second execution condition is met, a second control signal is generated according to the second execution condition to control the valve corresponding to the second signal. When the valve corresponding to the second signal is successfully controlled, if the third execution condition is met, a third control signal is generated according to the third execution condition to control the valve corresponding to the third signal.

[0088] Exemplarily, when isolating the downstream path of the reactor coolant, the first containment isolation valve, the downstream orifice isolation valve and the downstream isolation valve are generally closed in sequence manually by technicians. In this implementation, the first execution condition, the second execution condition and the third execution condition for automatic closing of the above-mentioned valves are pre-set according to the order of manual operation. When the first execution condition is met, a first control signal is issued to close the first containment isolation valve. When the first containment isolation valve is closed, if the second execution condition is met, a second control signal is issued to close the downstream orifice isolation valve. When the downstream orifice isolation valve is closed, if the third execution condition is met, a third control signal is issued to close the downstream isolation valve.

[0089] In another implementation, a breakpoint is set after each control logic is completed to prevent the next function from automatically starting if the conditions are not met, ensuring that the functions are executed in sequence according to the preset order. It is also convenient to pause the system operation through the breakpoint when the reactor system needs to be debugged or maintained, which facilitates the location and resolution of problems.

[0090] In this embodiment, the opening or closing of multiple valves in the chemical and volumetric system is controlled by control logic, which ensures the sequence and correctness of the operation, realizes the automatic control of the valves in the chemical and volumetric system, and greatly improves the efficiency and accuracy of the reactor coolant filling and discharging operations.

[0091] In some implementations, the control logic includes isolating the coolant discharge path of the reactor, and the control logic includes a first execution condition, a second execution condition, and a third execution condition arranged in order of precedence, wherein the first execution condition includes at least one of the following: the radioactive dose of a single loop of the reactor is higher than a first threshold, the liquid level value of the control tank of the chemical and volumetric system reaches a second threshold, and the chemical and volumetric system receives a safety isolation signal.

[0092] The control signal corresponding to the first execution condition is used to instruct closing the first containment isolation valve of the chemical and volume system.

[0093] The second execution condition includes at least one of the following: the downflow isolation valve of the chemical and volumetric system is not fully opened, the water level of the first-loop pressurizer of the reactor is lower than the third threshold, the chemical and volumetric system receives a charging isolation signal, the charging line pressure of the chemical and volumetric system is lower than the fourth threshold, the liquid level value of the control box reaches the second threshold, and the chemical and volumetric system receives a safety injection signal.

[0094] The control signal corresponding to the second execution condition is used to instruct closing the downflow orifice isolation valve of the chemical and volumetric system.

[0095] The third execution condition includes at least one of the following: the water level of the first-loop pressurizer is lower than the third threshold, the downstream discharge temperature of the chemical and volumetric system is not higher than the fifth threshold, the liquid level value of the volume control tank reaches the second threshold, and the chemical and volumetric system receives a safety injection signal.

[0096] The control signal corresponding to the third execution condition is used to instruct closing the downflow isolation valve of the chemical and volumetric system.

[0097] In the safe injection and residual heat removal system operation mode, during the reactor refueling overhaul or when the leakage isolation condition is triggered, the chemical and volumetric system is required to perform the reactor coolant leakage isolation function (i.e., isolate the reactor coolant discharge path).

[0098] Specifically, when at least one of the following conditions occurs: the radioactive dose in a first loop of the reactor is higher than a first threshold, the liquid level value in the control tank of the chemical and volumetric system reaches a second threshold, or the chemical and volumetric system receives a safety isolation signal, the control logic generates a first signal, and the first signal indicates closing the first containment isolation valve of the chemical and volumetric system.

[0099] When the first containment isolation valve is closed, if at least one of the following situations occurs: the downflow isolation valve of the chemical and volumetric system is not fully opened, the water level of the first-loop pressurizer of the reactor is lower than the third threshold, the chemical and volumetric system receives an upcharging isolation signal, the upcharging pipeline pressure of the chemical and volumetric system is lower than the fourth threshold, the liquid level value of the volume control tank of the chemical and volumetric system reaches the second threshold, and the chemical and volumetric system receives a safety injection signal, the control logic generates a second signal, and the second signal indicates to close the downflow orifice isolation valve of the chemical and volumetric system.

[0100] When the downhole orifice isolation valve is closed, if at least one of the following situations occurs: the water level of the reactor's primary-loop pressurizer is lower than the third threshold, the downhole flow temperature of the chemical and volumetric system is not higher than the fifth threshold, the liquid level value of the volume control tank of the chemical and volumetric system reaches the second threshold, and the chemical and volumetric system receives a safety injection signal, the control logic generates a third signal, which indicates to close the downhole isolation valve of the chemical and volumetric system.

[0101] It should be noted that the first threshold, the second threshold, the third threshold, the fourth threshold and the fifth threshold can be set according to actual conditions, and the safety isolation signal and the injection safety signal are issued by the protection system of the reactor.

[0102] In this implementation, by setting the execution conditions in a hierarchical manner, the automated operation of isolating the discharge path of the reactor coolant can be implemented to improve the efficiency and accuracy of the coolant discharge isolation operation of the reactor.

[0103] In some implementations, the control logic includes discharging the coolant of the reactor, and the control logic includes a fourth execution condition, a fifth execution condition, and a sixth execution condition arranged in a sequential order, wherein the fourth execution condition includes that the down-discharge pressure reducing regulating valve of the chemical and volumetric system is in an open state, there is no radioactive material in a loop of the reactor, and the chemical and volumetric system receives a first signal, and the first signal indicates that the coolant of the reactor is discharged.

[0104] The control signal corresponding to the fourth execution condition is used to instruct to open the first safety isolation valve of the chemical and volumetric system.

[0105] The fifth execution condition includes that the downstream flow temperature of the chemical and volumetric system is not higher than a fifth threshold value and the downstream orifice isolation valve of the chemical and volumetric system is in a closed state.

[0106] The control signal corresponding to the fifth execution condition is used to instruct opening of the downflow isolation valve of the chemical and volumetric system.

[0107] The sixth execution condition includes that the chemical and volume system does not receive a charging isolation signal, the water level of the primary-loop pressurizer of the reactor is not lower than a third threshold, and the charging line pressure of the chemical and volume system is not lower than a fourth threshold.

[0108] The control signal corresponding to the sixth execution condition is used to instruct opening of the downflow orifice isolation valve of the chemical and volumetric system.

[0109] After the safety injection and residual heat removal system operation mode is exited, the chemical and volumetric systems are required to perform the reactor coolant discharge operation function (i.e., discharge the reactor coolant).

[0110] Specifically, when the downward pressure reducing regulating valve of the chemical and volumetric system is in an open state, there is no radioactive material in a circuit, and the chemical and volumetric system receives a first signal instructing to discharge the coolant of the reactor, the control logic generates a fourth signal, and the fourth signal instructs to open the first safety isolation valve of the chemical and volumetric system, wherein the first signal is a signal manually sent by a technician.

[0111] When the first safety isolation valve is open, if the chemical and volumetric system does not receive a downstream flow temperature over-high signal and the downstream orifice isolation valve of the chemical and volumetric system is in a closed state, the control logic generates a fifth signal, which indicates to open the downstream isolation valve of the chemical and volumetric system.

[0112] When the first safety isolation valve is open, the downflow isolation valve is open and the downflow temperature of the chemical and volumetric system is not higher than the fifth threshold, if the water level of the reactor's primary-loop pressurizer is not lower than the third threshold and the upper filling line pressure of the chemical and volumetric system is not lower than the fourth threshold, the control logic generates a sixth signal, which indicates to open the downflow orifice isolation valve of the chemical and volumetric system.

[0113] In this implementation, by setting the execution conditions in a hierarchical manner, the automated operation of discharging the reactor coolant can be achieved, so as to improve the efficiency and accuracy of the operation of discharging the reactor coolant.

[0114] In some implementations, the control logic includes replenishing coolant into the reactor, and the control logic includes a seventh execution condition and an eighth execution condition arranged in a sequential order, wherein the seventh execution condition includes the chemical and volumetric system receiving a second signal, and the second signal indicates that the coolant of the reactor is replenished.

[0115] The control signal corresponding to the seventh execution condition is used to instruct opening the downstream isolation valve of the control tank of the chemical and volume system, the second containment isolation valve of the chemical and volume system, and the charging isolation valve of the chemical and volume system.

[0116] The eighth execution condition includes that the downstream isolation valve of the containment tank is in an open state, the second containment isolation valve is in an open state, and the upper charging isolation valve is in an open state.

[0117] The control signal corresponding to the eighth execution condition is used to instruct to turn on the charging pump of the chemical and volumetric system.

[0118] During the period of reactor loading to the start of primary loop water filling, as well as in the reactor maintenance cold shutdown mode, and during the primary loop drainage through the chemical and volumetric system, it is necessary to operate the chemical and volumetric system to perform the function of charging and commissioning the reactor coolant (i.e., replenishing the reactor coolant).

[0119] Specifically, when the chemical and volumetric system receives the second signal indicating that the coolant of the reactor is to be replenished, the control logic generates a seventh signal, which indicates to open the downstream isolation valve of the control box of the chemical and volumetric system, the second containment isolation valve of the chemical and volumetric system, and the charging isolation valve of the chemical and volumetric system, wherein the second signal is a signal manually sent by a technician.

[0120] When the isolation valve downstream of the containment tank, the isolation valve of the second containment shell, and the charging isolation valve are all opened, the control logic generates an eighth signal, and the eighth signal instructs to open the charging pump of the chemical and volumetric system.

[0121] In this implementation, by setting the execution conditions in a hierarchical manner, the automated operation of replenishing the reactor coolant can be realized, so as to improve the efficiency and accuracy of the reactor coolant charging and commissioning operation.

[0122] In some implementations, the control logic includes isolating a replenishment path for the coolant of the reactor, and the control logic includes a ninth execution condition, a tenth execution condition, an eleventh execution condition, and a twelfth execution condition arranged in a sequential order, wherein the ninth execution condition includes that the chemical and volumetric system receives a third signal, the liquid level value of the volume control tank of the chemical and volumetric system reaches a second threshold, and the third signal indicates that the replenishment path for the coolant of the reactor is to be isolated.

[0123] The control signal corresponding to the ninth execution condition is used to instruct closing the isolation valve downstream of the volume control tank of the chemical and volume system.

[0124] The tenth execution condition includes at least one of the following: the chemical and volume system receives an injection signal, and the chemical and volume system receives a containment isolation signal.

[0125] The control signal corresponding to the tenth execution condition is used to instruct closing the second containment isolation valve of the chemical and volume system.

[0126] The eleventh execution condition includes at least one of the following: the water level of the primary-loop pressurizer of the reactor is higher than a sixth threshold value, and the chemical and volume system receives a safety injection signal.

[0127] The control signal corresponding to the eleventh execution condition is used to instruct closing the charging isolation valve of the chemical and volume system.

[0128] The twelfth execution condition includes at least one of the following: the chemical and volumetric system receives a charging pump shutdown signal, the liquid level value of the volume control tank of the chemical and volumetric system reaches a second threshold, the inlet pressure of the charging pump of the chemical and volumetric system is lower than a seventh threshold, and the outlet pressure of the charging pump of the chemical and volumetric system is higher than an eighth threshold.

[0129] The control signal corresponding to the twelfth execution condition is used to instruct to turn off the charging pump of the chemical and volumetric system.

[0130] Specifically, when the chemical and volumetric system receives the third signal indicating that the replenishment path of the reactor's coolant is to be isolated and the liquid level value of the control tank of the chemical and volumetric system reaches the second threshold, the control logic generates a ninth signal, which indicates closing the isolation valve downstream of the control tank of the chemical and volumetric system, wherein the third signal is a signal manually issued by a technician.

[0131] When the isolation valve downstream of the containment tank is closed, if the chemical and volume system receives an injection signal and / or a containment isolation signal, the control logic generates a tenth signal, which indicates the closing of the second containment isolation valve of the chemical and volume system.

[0132] When the second containment isolation valve is closed, if the water level of a loop pressurizer is higher than the sixth threshold and / or the chemical and volumetric system receives a safety injection signal, the control logic generates an eleventh signal, which instructs the closing of the charging isolation valve of the chemical and volumetric system.

[0133] When the charging isolation valve is closed, if at least one of the following situations occurs: the chemical and volumetric system receives a charging pump shutdown signal, the liquid level value of the volume control box reaches the first threshold, the inlet pressure of the chemical and volumetric system's charging pump is lower than the seventh threshold, and the outlet pressure of the chemical and volumetric system's charging pump is higher than the eighth threshold, the control logic generates a twelfth signal, which indicates to shut down the chemical and volumetric system's charging pump.

[0134] It should be noted that the sixth threshold, the seventh threshold and the eighth threshold can all be set according to actual conditions.

[0135] In this implementation, by setting the execution conditions in a hierarchical manner, the automated operation of isolating the reactor coolant replenishment path can be implemented to improve the efficiency and accuracy of the reactor coolant charging and isolation operation.
