Description

Technical Field

[0001] The present application relates to the technical field, and in particular to a method, device and product for adjusting the quadrant power tilt value of a reactor core. Background Art

[0002] Nuclear power plants regularly monitor the reactor's Quadrant Power Tilt Value (TILT) to ensure it remains within specified safety limits. The TILT measures the balance of power distribution across the reactor core's quadrants and is a key parameter for monitoring safe nuclear power plant operation. If the TILT for a particular quadrant is too high, it indicates excessive power density in the corresponding area, potentially leading to fuel assembly overheating and increasing the risk of fuel damage and radioactive release.

[0003] The current technical solution involves reducing the reactor power by ≥3% RTP for every 1% increase in the quadrant power tilt value over a preset period of time when the quadrant power tilt value exceeds the upper limit. This directly results in a reduction in overall power, leading to a decrease in the plant's power generation and direct economic losses. Furthermore, after reducing the power, the reactor must undergo a supplementary safety assessment before returning to full power. Due to the complex and time-consuming safety assessment process, the reactor will operate at a reduced power level for an extended period, impacting the plant's economic profitability. Furthermore, the unit will remain in the limited core operating (LCO) state for extended periods, reducing its safety margin.

[0004] Therefore, how to ensure the economic benefits of the nuclear power plant and improve the margin for safe operation when adjusting the quadrant power tilt value of the reactor core is a technical problem that technical personnel in this field currently need to solve.

[0050] Nuclear power plants regularly monitor the reactor's Quadrant Power Tilt Value (TILT) to ensure it remains within specified safety limits. The TILT is a parameter used to measure the balance of power distribution between the different quadrants in the reactor core and is a key parameter for monitoring the safe operation of nuclear power plants. If the TILT value of a particular quadrant is too high, it indicates excessive power density in the corresponding area, potentially leading to fuel assembly overheating and increasing the risk of fuel damage and radioactive release.

[0051] During the post-refueling startup of the second cycle (D1C02) of Unit 1 of a nuclear power plant, the maximum quadrant power tilt value (DA) was 1.0593 at an 8% power level (8% of the reactor's design maximum thermal power), 1.0502 at a 50% power level (50% of the design maximum thermal power), 1.0417 at an 83% power level (83% of the design maximum thermal power), and 1.0314 at a 100% power level (100% of the design maximum thermal power). These values exceeded the limit of 1.02 specified in the technical specifications. According to the technical specifications, the unit was forced to operate at 97% power for 14 days until the power level was allowed to be increased to 100% after passing a nuclear safety assessment. The current technical solution requires that when the quadrant power tilt value for a particular quadrant exceeds the upper limit, the reactor thermal power (RTP) must be reduced by at least 3% of the reactor thermal power for each 1% increase in the quadrant power tilt value over a predetermined period. This directly results in a reduction in overall power, leading to a decrease in nuclear power plant power generation and direct economic losses. Furthermore, after the power reduction, the reactor must undergo a supplementary safety assessment before returning to full power. Due to the complex and time-consuming safety assessment process, the unit will remain in a sub-full power state for an extended period, impacting the plant's economic profitability. Furthermore, the unit will remain in the core operating limits (LCO) state for extended periods, reducing the unit's safety margin.

[0052] Therefore, how to ensure the economic benefits of the nuclear power plant and improve the margin for safe operation when adjusting the quadrant power tilt value of the reactor core is a technical problem that technical personnel in this field currently need to solve.

[0053] The present invention provides a method for controlling quadrant power tilt values in a reactor core. The method comprises determining quadrant power tilt values in the reactor core that exceed a preset threshold value to obtain a target quadrant power tilt value. Based on the target quadrant power tilt value, a corresponding target temperature control rod is determined, and a target number of desynchronization steps for the target temperature control rod is determined. Desynchronization operations are performed on the target temperature control rod based on the target number of desynchronization steps to adjust the target quadrant power tilt value. The temperature control rod is a tool for rapidly controlling reactor reactivity. When the temperature control rod is raised, reactor power increases, and when the temperature control rod is lowered, reactor power decreases. The method controls the target number of desynchronization steps of the target temperature control rod to restore the target quadrant power tilt value of the core to within a preset threshold. By locally adjusting the temperature control rod, the power of the corresponding quadrant is specifically reduced without affecting the total output power of the entire reactor, thereby avoiding direct economic losses caused by power reduction. Furthermore, since the total power of the reactor is not reduced, the reactor can still operate at full power, avoiding the need for a supplementary safety assessment due to power reduction and the economic impact during the supplementary safety assessment. Furthermore, this method prevents the reactor from being in a restricted core operating state for extended periods, reducing the impact on safe operating margins. Therefore, this method can safeguard the economic benefits of the nuclear power plant and improve safe operating margins when adjusting the quadrant power tilt value of the reactor core.

[0054] An embodiment of the present application provides a method for adjusting the quadrant power tilt value of a reactor core, which can be executed by a processor of a terminal device when running a corresponding computer program.

[0055] Figure 1 This is a flow chart of a method for adjusting quadrant power tilt values of a reactor core provided in an embodiment of the present application. For ease of illustration, only the portion relevant to this embodiment is shown. The method provided in this embodiment includes the following steps:

[0056] S100: Determine a quadrant power tilt value in a reactor core that exceeds a preset threshold value, and obtain a target quadrant power tilt value.

[0057] It should be noted that the core of a reactor is usually divided into four quadrants, each quadrant being a quarter of the core and containing an equal number of fuel assemblies.

[0058] In practical applications, in order to provide more refined power distribution control and safety monitoring, the core is divided into eight quadrants. Figure 2 and Figure 3 A schematic diagram of dividing the core into eight quadrants is provided in an embodiment of the present application. Figure 2 As shown in Figure 1, the core is divided into four quadrants by horizontal and vertical lines, namely Q1 to Q4; Figure 3As shown, the horizontal and vertical lines are rotated 45° clockwise or counterclockwise to obtain two diagonal lines, which are used to divide the core into four quadrants, namely Q5 to Q8.

[0059] The quadrant power tilt value is a parameter used to measure whether the power distribution between different quadrants in the reactor core is balanced. It is one of the important parameters for detecting the safe operation of nuclear power plants. The quadrant power tilt value is also an indicator for measuring the symmetry of the radial power distribution of the core. It represents the ratio of the average power of a quadrant of the reactor core to the average power of the entire core, that is:

[0060]

[0061] It should be noted that a preset threshold value corresponding to the quadrant power tilt value is pre-set. If the quadrant power tilt value of a quadrant is greater than the preset threshold value, it means that the average power of the quadrant is greater than the average power of the entire core. Therefore, the quadrant power tilt value is determined as the target quadrant power tilt value.

[0062] In practical applications, the preset threshold can range from 0.8 to 1.1. In one specific example, considering that the actual power of the reactor core cannot achieve the theoretically perfect 1 / 4 rotational symmetry due to factors such as the incomplete symmetry of the three loops and component deformation, the preset threshold for the quadrant power tilt value is set to 1.02, indicating that the average power of any quadrant must not exceed 1.02 times the average power of the entire core. If it is determined that the quadrant power tilt value exceeds the preset threshold, it indicates that appropriate measures need to be taken to adjust the power distribution of the core to ensure the safe operation of the reactor; therefore, the quadrant power tilt value that exceeds the preset threshold is determined as the target quadrant power tilt value.

[0063] Specifically, for each quadrant, the corresponding quadrant power tilt value is calculated according to a preset detection period to monitor the symmetry of the core's radial power distribution. The quadrant power tilt value for each quadrant of the core can be measured according to the preset detection period during startup testing, after refueling, and during power operation to ensure that the reactor core operates within a safe range.

[0064] In practical applications, the maximum value of the quadrant power tilt values of the eight quadrants can be selected as the maximum quadrant power tilt value (DA); if the maximum quadrant power tilt value is greater than the preset threshold, the quadrant power tilt value in the reactor core that exceeds the preset threshold is determined to obtain the target quadrant power tilt value.

[0065] S200: Determine a corresponding target temperature adjustment rod according to the target quadrant power tilt value, and determine a target number of out-of-step steps of the target temperature adjustment rod.

[0066] Temperature control rods (R rods), also known as control rods, are used to regulate the power and temperature of a nuclear reactor core. They are typically made of neutron-absorbing materials, such as boron steel, cadmium, or silver-indium-cadmium alloys. By absorbing neutrons, they control the rate of nuclear fission reactions.

[0067] There are 8 bundles of temperature control rods in the reactor, divided into two groups (R1 and R2). The 4 bundles of temperature control rods in each group are distributed according to a certain symmetry pattern, such as 1 / 4 rotational symmetry. Figure 2 and Figure 3 As shown, each quadrant contains a bundle of temperature control rods, and the specific position of each temperature control rod within the corresponding quadrant is determined. In actual unit control, the four temperature control rods in the same bundle operate in unison, being raised or lowered simultaneously. If the quadrant power tilt value of a particular quadrant exceeds a preset threshold—that is, if the average power in that quadrant exceeds the average power of the entire core—the temperature control rod in that quadrant is identified as the target temperature control rod.

[0068] When performing out-of-step operation, relative to the other 1 / 4 rotationally symmetrical temperature regulating rods in the same group, the positions of the other temperature regulating rods remain unchanged, and the target temperature regulating rod is adjusted to be inserted a few more "steps" than the other temperature regulating rods, so as to increase the absorption of neutrons by the target temperature regulating rod, thereby reducing the target quadrant to which the target quadrant power tilt value in the core belongs (such as Figure 2 or Figure 3 power in any of the quarter areas shown).

[0069] Specifically, after determining the target quadrant power tilt value, the target quadrant to which the target quadrant power tilt value belongs is determined, and then the corresponding target temperature adjustment rod is determined according to the target quadrant. The target temperature adjustment rod is the temperature adjustment rod that needs to be operated out of step.

[0070] Desynchronization refers to moving the target temperature control rod so that its position is no longer synchronized with the other temperature control rods. Specifically, the target temperature control rod is raised or lowered to adjust the power of the target quadrant. When the temperature control rod is raised, the reactor power increases, and when the temperature control rod is lowered, the reactor power decreases.

[0071] Among them, the target out-of-step step number refers to the specific distance unit that the target temperature control rod moves in the reactor core. Each out-of-step step number corresponds to a small distance that controls the movement of the target temperature control rod, that is, the number of steps that the target temperature control rod is inserted or withdrawn more than other control rods.

[0072] S300: performing a step-out operation on the target temperature adjustment rod according to the target step-out number to adjust the target quadrant power tilt value.

[0073] Specifically, after the target temperature adjustment rod and the target out-of-step number corresponding to the target temperature adjustment rod are determined, an out-of-step operation is performed on the target temperature adjustment rod according to the target out-of-step number.

[0074] Specifically, if the target quadrant power tilt value exceeds a preset threshold, the insertion depth of the target temperature adjustment rod can be increased to absorb more neutrons, reducing the power in the corresponding area, thereby adjusting the target quadrant power tilt value. Specifically, downward insertion refers to the process of moving the temperature adjustment rod downward from its initial position into the reactor core.

[0075] Specifically, by locking the temperature adjustment rods, the temperature adjustment rods other than the target temperature adjustment rod are locked, and the target step-out number corresponding to the target temperature adjustment rod is inserted downward; the step-out is maintained until the target quadrant power tilt value gradually decreases.

[0076] After adjusting the target quadrant power tilt value, determine whether the adjusted target quadrant power tilt value is reduced to within the preset threshold; if the adjusted target quadrant power tilt value is less than the preset threshold, end the process; if the adjusted target quadrant power tilt value still exceeds the preset threshold, it is necessary to further determine the number of out-of-step steps of the target temperature adjustment rod until the adjusted target quadrant power tilt value is less than the preset threshold, that is, the reactor core achieves the ideal power distribution.

[0077] The present invention provides a method for controlling the quadrant power tilt value of a reactor core. The method includes determining a target quadrant power tilt value in the reactor core that exceeds a preset threshold; determining a corresponding target temperature control rod based on the target quadrant power tilt value, and determining a target desynchronization step number for the target temperature control rod; and performing a desynchronization operation on the target temperature control rod based on the target desynchronization step number to adjust the target quadrant power tilt value. The temperature control rod is a tool for rapidly controlling the reactor's reactivity. When the temperature control rod is raised, the reactor power increases, and when the temperature control rod is lowered, the reactor power decreases. The method controls the target desynchronization step number of the target temperature control rod to restore the target quadrant power tilt value of the core to within the preset threshold. By locally adjusting the temperature control rod, the power of the corresponding quadrant is specifically reduced without affecting the total output power of the entire reactor, thereby avoiding direct economic losses caused by power reduction. Furthermore, since the total power of the reactor is not reduced, the reactor can still operate at full power, avoiding the need for a supplementary safety assessment due to power reduction and the economic impact during the supplementary safety assessment. Furthermore, this method prevents the reactor from being in a restricted core operating state for extended periods, reducing the impact on safe operating margins. Therefore, this method can safeguard the economic benefits of the nuclear power plant and improve safe operating margins when adjusting the quadrant power tilt value of the reactor core.

[0078] Based on the above embodiment, this embodiment further illustrates and optimizes the technical solution. Specifically, in this embodiment, a method for adjusting the quadrant power tilt value of a reactor core further includes:

[0079] Determine the nuclear enthalpy rise heat channeling factor of the reactor core;

[0080] If the nuclear enthalpy rise heat channel factor is within the corresponding preset range, a step of performing a step-out operation on the target temperature adjustment rod according to the target step-out number is executed to adjust the target quadrant power tilt value.

[0081] The nuclear enthalpy rise hot channel factor (HCF) is a key parameter for assessing the thermal safety of a reactor core. It is used to evaluate the thermal safety margin of the hottest point in the core (the hot channel) relative to average conditions. A value greater than 1 indicates that the heat load on the hot channel is above average.

[0082] Specifically, when the temperature control rods lose synchronization, local core power is reconfigured, which can easily lead to an increase in the nuclear enthalpy rise heat channel factor. To prevent the nuclear enthalpy rise heat channel factor from exceeding the corresponding preset range due to synchronization loss, it is necessary to evaluate the impact of temperature control rod synchronization loss on the nuclear enthalpy rise heat channel factor, that is, to calculate the nuclear enthalpy rise heat channel factor.

[0083] After calculating the nuclear enthalpy rise heat channel factor of the reactor core, it is determined whether the nuclear enthalpy rise heat channel factor is within a corresponding preset range. If the nuclear enthalpy rise heat channel factor is within the corresponding preset range, it indicates that the out-of-step operation has not caused the nuclear enthalpy rise heat channel factor to exceed the safety limit, and the out-of-step operation has not negatively impacted the reactor core. Therefore, a step of performing an out-of-step operation on the target temperature adjustment rod according to a target out-of-step step number to adjust the target quadrant power tilt value is performed. If the nuclear enthalpy rise heat channel factor exceeds the corresponding preset range, it indicates that the out-of-step operation has caused the nuclear enthalpy rise heat channel factor to exceed the safety limit, and the out-of-step operation has negatively impacted the reactor core. In this case, to prevent the actual power of the reactor core from exceeding the power limit range allowed by its design or operating specifications, before the out-of-step operation, the actual power of the reactor can be reduced to below its full power state, and then the target temperature adjustment rod can be performed according to the target out-of-step step number to adjust the target quadrant power tilt value. After the target quadrant power tilt value is reduced to within a preset threshold, the pre-reduced power can be restored.

[0084] According to the method of this embodiment, whether the out-of-step operation will have a negative impact on the reactor core can be determined in advance before the out-of-step operation, thereby ensuring the safety of the reactor core and ensuring the safe and stable operation of the reactor.

[0085] In order to avoid excessive concentration of reactor core power in the upper or lower part, which would cause unacceptable consequences of reactor accidents, an operating diagram is established in the reactor design, and the axial power deviation must be kept within the range specified in the operating diagram (it must not exceed the boundaries of the operating diagram in non-accident situations, and must not exceed one zone when the unit is stable). Before the out-of-step operation is implemented, it is necessary to assess whether the axial power deviation will not exceed the range specified in the allowable diagram after the out-of-step operation. The allowable diagram refers to the safe range within which various parameters of the reactor (such as power, temperature, etc.) should be maintained under specific operating conditions. Based on the above embodiments, this embodiment further illustrates and optimizes the technical solution. Specifically, in this embodiment, a method for adjusting the quadrant power tilt value of a reactor core also includes:

[0086] Obtaining axial power deviations corresponding to a plurality of detection positions of the reactor core;

[0087] If the difference between any axial power deviation and the other axial power deviations is less than the deviation threshold, a step of performing a step-out operation on the target temperature adjustment rod according to the target step-out number is executed to adjust the target quadrant power tilt value.

[0088] Among them, axial power deviation (ΔI) is a key parameter for evaluating the safety of reactor core power distribution; specifically, it refers to the ratio of the deviation between the upper power and the lower power of the reactor core to the rated power.

[0089] Specifically, power range detectors are respectively arranged at multiple detection positions outside the reactor in advance to detect axial power deviation.

[0090] When the target temperature adjustment rod is out of step, the axial power deviation displayed by some power range detectors may be larger than the axial power deviation displayed by other power range detectors. In other words, the difference between the axial power deviation displayed by a certain power range detector and the axial power deviation displayed by other power range detectors is greater than the deviation threshold.

[0091] In this embodiment, if the difference between any axial power deviation and the other axial power deviations is greater than the deviation threshold, this indicates that if the target temperature adjustment rod is desynchronized for the target number of steps, the axial power deviation will exceed the allowable range specified in the diagram after the desynchronization. In this case, the power can be partially reduced in advance, and then the target temperature adjustment rod can be desynchronized according to the target number of steps to adjust the target quadrant power tilt value. After the target quadrant power tilt value is reduced to within the preset threshold, the pre-reduced power can be restored.

[0092] If the difference between any axial power deviation and the other axial power deviations is less than the deviation threshold, it means that if the target temperature adjustment rod is operated for the target number of out-of-step steps, the axial power deviation will not exceed the range specified in the allowable diagram after the out-of-step operation. Therefore, the target temperature adjustment rod is operated for out-of-step according to the target number of out-of-step steps to adjust the target quadrant power tilt value. During the out-of-step operation, it is necessary to ensure that the axial power deviation does not exceed the ladder diagram or zone 1.

[0093] In another specific embodiment, a power range detector can be used to collect axial power deviation and power (total power or local power of the reactor core, in MW); correspondingly, if the difference between any axial power deviation and other axial power deviations is greater than the deviation threshold, or the difference between any power and other powers is greater than the difference threshold, it means that if the target out-of-step number of steps is executed on the target temperature adjustment rod, the sum power will cause the axial power deviation after the out-of-step to exceed the range specified in the allowable diagram, or the power will exceed the power limit range. In this case, part of the power can be reduced in advance, and then the target temperature adjustment rod can be out of step according to the target out-of-step number of steps to adjust the target quadrant power tilt value. After the target quadrant power tilt value is reduced to within the preset threshold, the pre-reduced part of the power can be restored.

[0094] If the difference between any axial power deviation and other axial power deviations is less than the deviation threshold, and the difference between any power and other powers is less than the difference threshold, then the step of performing a step-out operation on the target temperature adjustment rod according to the target step-out number is executed to adjust the target quadrant power tilt value.

[0095] It should be noted that after a step-out operation, a power range calibration test should be performed as soon as possible to calibrate the power display and axial power deviation of the power range detector. The power range calibration test uses the theoretical library of the step-out lower rod position (to avoid excessive component power deviation) to confirm that the quadrant tilt has returned to the preset threshold. The power and axial power deviation are calibrated to eliminate the impact of the step-out on the power range display.

[0096] According to the method of this embodiment, whether the out-of-step operation will have a negative impact on the reactor core can be determined in advance before the out-of-step operation, thereby ensuring the safety of the reactor core and ensuring the safe and stable operation of the reactor.

[0097] In a specific embodiment, determining the nuclear enthalpy rise heat channel factor of the reactor core includes:

[0098] Determine the total power of the hot channels in the reactor core;

[0099] Calculate the average power of all fuel rods in the reactor core;

[0100] The nuclear enthalpy rise heat channel factor is determined based on the quotient of the total power and the average power.

[0101] Specifically, within the reactor core, uneven power distribution occurs locally due to factors such as the position of control rods, the arrangement of fuel rods, and the flow characteristics of the coolant. This, in turn, can result in higher thermal loads on the fuel rods in certain areas of the reactor core. Excessive thermal loads can cause fuel rod temperatures to rise, affecting their mechanical properties and chemical stability, and increasing the risk of fuel rod damage and radioactive release.

[0102] In this embodiment, the highest-power fuel rod line in the reactor core, known as the hot channel, is identified. The integrated power of all fuel rods along this hot channel is calculated to obtain the total power along that channel. The average power of all fuel rods is then calculated. The total power of the hot channel is divided by the average power to obtain the hot channel factor for nuclear enthalpy rise.

[0103] According to the method of this embodiment, the nuclear enthalpy rise heat channel factor can be determined efficiently and conveniently, thereby improving the efficiency of adjusting the quadrant power tilt value of the reactor core.

[0104] Based on the above embodiment, this embodiment further illustrates and optimizes the technical solution. Specifically, in this embodiment, the corresponding target temperature adjustment rod is determined according to the target quadrant power tilt value, and the target number of out-of-step steps of the target temperature adjustment rod is determined, including:

[0105] Obtaining a first correspondence between quadrants of the reactor core and temperature regulating rods;

[0106] Determining a corresponding target temperature adjustment rod according to the target quadrant to which the target quadrant power tilt value belongs and the first corresponding relationship;

[0107] Determine the target number of desynchronization steps for the target temperature adjustment rod.

[0108] In this embodiment, the target quadrant to which the target quadrant power tilt value belongs is first determined. The target quadrant is the quadrant corresponding to the quadrant whose quadrant power tilt value exceeds a preset threshold.

[0109] Then, a first correspondence between the quadrants of the reactor core and the temperature regulating rods is obtained; wherein the first correspondence between the quadrants of the reactor core and the temperature regulating rods can be represented by a table or a function. Specifically, Figure 4 This is a distribution diagram of temperature regulating rods (R rods) in a reactor provided in an embodiment of the present application. Figure 4 The first correspondence between the quadrants and the temperature regulating rods of the reactor core is determined according to the correspondence table between the quadrants and the out-of-step control rods shown in Table 1.

[0110] Table 1 Correspondence between quadrants and temperature adjustment rods

[0111]

[0112]

[0113] Based on the one-to-one correspondence between quadrants and temperature adjustment rods, the corresponding target temperature adjustment rod is determined based on the target quadrant to which the target quadrant power tilt value belongs and the first correspondence. For example, if the target quadrant to which the target quadrant power tilt value belongs is Q3, then the corresponding target temperature adjustment rod is determined to be K10 according to the first correspondence. If the target quadrant to which the target quadrant power tilt value belongs is Q7, then the corresponding target temperature adjustment rod is determined to be H14 according to the first correspondence.

[0114] After the target temperature adjustment rod is determined, a target number of out-of-step steps corresponding to the target temperature adjustment rod is determined.

[0115] According to the method of this embodiment, the target temperature regulating rod can be determined efficiently and conveniently, thereby improving the efficiency of adjusting the quadrant power tilt value of the reactor core.

[0116] Based on the above embodiment, this embodiment further illustrates and optimizes the technical solution. Specifically, in this embodiment, determining the target number of out-of-step steps of the target temperature adjustment rod includes:

[0117] Obtaining a second corresponding relationship between the number of out-of-step steps of the temperature adjustment rod and the range of change of the quadrant power tilt value;

[0118] Determining an adjustment amount of the target quadrant power tilt value according to a difference between the target quadrant power tilt value and a preset threshold;

[0119] The target number of out-of-step steps of the target temperature regulating rod is determined according to the target quadrant power tilt value adjustment amount and the second corresponding relationship.

[0120] Specifically, the effectiveness of the number of out-of-step steps of the temperature control rod in adjusting the quadrant power tilt value can be determined based on practical experience or a nuclear reactor physics calculation model. Specifically, the range of quadrant power tilt values that can be affected by the number of out-of-step steps of the temperature control rod can be determined. In other words, a second correspondence between the number of out-of-step steps of the temperature control rod and the range of quadrant power tilt values can be determined. Specifically, the second correspondence between the number of out-of-step steps of the temperature control rod and the range of quadrant power tilt values can be represented using a table or function.

[0121] In a specific embodiment, at different operating stages of a uniform reactor core, such as the beginning of life (BOL), middle of life (MOL), and end of life (EOL), a temperature regulating rod (R rod) in a specific quadrant of the core is subjected to a step-out operation, specifically 3 steps, 6 steps, 9 steps, and 12 steps of step-out operation, to determine the effectiveness of different step-out steps in adjusting the quadrant power tilt value, and then determine a second correspondence between the step-out step number and the range of change of the quadrant power tilt value. Table 2 is an analysis table of the effectiveness of the step-out step number of the temperature regulating rod for adjusting the quadrant power tilt value provided in an embodiment of the present application.

[0122] Table 2 Analysis of the effectiveness of the temperature adjustment rod's step loss number on the adjustment of the quadrant power tilt value

[0123]

[0124] As shown in Table 2, a six-step desynchronization is expected to reduce the quadrant power tilt value by 0.003 to 0.005, meaning that the quadrant power tilt range corresponding to six desynchronization steps is 0.003 to 0.005. A 12-step desynchronization is expected to reduce the quadrant power tilt value by 0.007 to 0.009, meaning that the quadrant power tilt range corresponding to 12 desynchronization steps is 0.007 to 0.009. It should be noted that this embodiment does not limit the specific content of the second correspondence between the temperature adjustment rod and the quadrant power tilt value.

[0125] Specifically, the target quadrant power tilt value adjustment amount is the quadrant power tilt value corresponding to the target quadrant power tilt value exceeding the preset threshold. In this embodiment, the target quadrant power tilt value adjustment amount is determined based on the difference between the target quadrant power tilt value and the preset threshold.

[0126] Then, the quadrant power tilt value variation range corresponding to the target quadrant power tilt value adjustment amount is determined to obtain the target quadrant power tilt value variation range; based on the second corresponding relationship between the number of out-of-step steps of the temperature adjustment rod and the quadrant power tilt value variation range, the number of out-of-step steps corresponding to the target quadrant power tilt variation range is determined as the target out-of-step step number of the target temperature adjustment rod.

[0127] In this embodiment, the target number of out-of-step steps required to restore the target quadrant power tilt value to within a preset threshold is determined based on the impact of different out-of-step step counts on the quadrant power tilt value. In other words, based on the extent to which the target quadrant power tilt exceeds the threshold, the target number of out-of-step steps required for the target temperature adjustment rod is determined based on the target quadrant power tilt value adjustment amount, with the goal of restoring the exceeded quadrant power tilt value to within the preset threshold.

[0128] In a specific example, after determining the target number of out-of-step steps for the target temperature adjustment rod based on the target quadrant power tilt value adjustment amount, it is determined whether the target number of out-of-step steps is greater than 12 steps; if the target number of out-of-step steps is greater than 12 steps, the process is terminated without performing the out-of-step operation; if the target number of out-of-step steps is less than or equal to 12 steps, the out-of-step operation is performed on the target temperature adjustment rod based on the target number of out-of-step steps to adjust the target quadrant power tilt value.

[0129] According to the method of this embodiment, the target number of out-of-step steps can be determined efficiently and conveniently, so as to improve the efficiency of adjusting the quadrant power tilt value of the reactor core.

[0130] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
