Description

Technical Field

[0001] The present application relates to the field of civil engineering materials, and in particular to a reinforced concrete boric acid corrosion alarm method, device, equipment, medium and product. Background Art

[0002] During the operation of nuclear power plants, boron-containing water is used to control the neutron flux density. Therefore, boric acid solutions are widely used in nuclear power plants, including spent fuel pools and refueling tanks. In recent years, with the long-term operation of nuclear power plants, it has been found that due to defects in the bottom plate welds of the steel lining of the refueling tanks, leakage is prone to occur, which directly leads to the boric acid solution entering the reinforced concrete structure of the refueling tanks.

[0003] The design life of a nuclear power plant is 60 years, which means that the reinforced concrete structure of the refueling water tank may be used for more than 60 years. However, the corrosion of reinforced concrete by boric acid is irreversible and may not have much impact in the short term. However, as time goes by, if the degree of corrosion of reinforced concrete is not judged or predicted, it may lead to a decrease in the bearing capacity of the reinforced concrete structure of the refueling water tank, and it is uncertain whether it can meet its safety function.

[0004] Therefore, the existing technology lacks a method for predicting the service life of a nuclear power plant, resulting in the inability to ensure the safety of the use of the nuclear power plant.

[0050] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0051] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0052] The main solution of the embodiment of the present application is as follows: receiving nuclear power plant design standard information; parsing the nuclear power plant design standard information to obtain an exemplary boric acid solution temperature set, an exemplary boric acid solution concentration set, and exemplary reinforced concrete information; generating several experimental reinforced concrete structures based on the exemplary reinforced concrete information; constructing a final prediction model using the exemplary boric acid solution temperature set, the exemplary boric acid solution concentration set, and the several experimental reinforced concrete structures. Strength tests are performed on the several experimental reinforced concrete structures using the exemplary boric acid solution temperature set and the exemplary boric acid solution concentration set to obtain a first analysis result; microscopic inspection of the several experimental reinforced concrete structures using the exemplary boric acid solution temperature set and the exemplary boric acid solution concentration set to obtain a second analysis result; and constructing a final prediction model using the first and second analysis results. A first boric acid solution concentration is selected based on the exemplary boric acid solution concentration set; the first experimental reinforced concrete structure, the second experimental reinforced concrete structure and the third experimental reinforced concrete structure are respectively immersed in the first boric acid solution concentration, and the temperature of the immersion solution of the first experimental reinforced concrete structure, the second experimental reinforced concrete structure and the third experimental reinforced concrete structure is adjusted based on the exemplary boric acid solution temperature set to obtain the immersed first experimental reinforced concrete structure, the second experimental reinforced concrete structure and the third experimental reinforced concrete structure; the compressive strength of the immersed first experimental reinforced concrete structure, the second experimental reinforced concrete structure and the third experimental reinforced concrete structure is detected to obtain a first compressive strength, a second compressive strength and a third compressive strength; the first compressive strength, the second compressive strength and the third compressive strength are summarized and analyzed to obtain a first analysis result. A first boric acid solution temperature is selected based on the exemplary boric acid solution temperature set; the fourth experimental reinforced concrete structure, the fifth experimental reinforced concrete structure and the sixth experimental reinforced concrete structure are immersed according to the first boric acid solution temperature, and the concentration of the immersion solution of the fourth experimental reinforced concrete structure, the fifth experimental reinforced concrete structure and the sixth experimental reinforced concrete structure is adjusted based on the exemplary boric acid solution concentration set to obtain the immersed fourth experimental reinforced concrete structure, the fifth experimental reinforced concrete structure and the sixth experimental reinforced concrete structure; a microscopic analysis of the immersed fourth experimental reinforced concrete structure, the fifth experimental reinforced concrete structure and the sixth experimental reinforced concrete structure is performed by scanning electron microscopy and mercury intrusion porosimetry to obtain first corrosion data, second corrosion data and third corrosion data; the first corrosion data, the second corrosion data and the third corrosion data are summarized and analyzed to obtain a second analysis result.Environmental information is collected based on pre-set environmental collection nodes. Based on this environmental information, the final prediction model is used to predict reinforced concrete corrosion information for the nuclear power plant. This reinforced concrete corrosion information includes the degree of corrosion and corrosion trend. This solves the problem of being unable to predict the degree of reinforced concrete corrosion based on actual nuclear power plant usage, which can lead to nuclear safety accidents. This enables warnings for reinforced concrete corrosion and improves the efficiency of these warnings. Based on the present invention, a method for warning against boric acid corrosion of reinforced concrete is designed based on the fact that boric acid corrosion of reinforced concrete is irreversible. Without a method to determine or predict the degree of corrosion, this can lead to a decrease in the bearing capacity of the reinforced concrete structure, uncertainty about whether it meets its safety requirements, and potentially a complete accident. The effectiveness of the present method for warning against boric acid corrosion of reinforced concrete has been verified in real-world situations. Finally, the accuracy of warnings for reinforced concrete corrosion has been significantly improved using the present method.

[0053] In this embodiment, for ease of description, the reinforced concrete boric acid corrosion alarm device is used as the execution subject for explanation.

[0054] The design life of a nuclear power plant in existing technology is 60 years, and the need for "life extension" also needs to be considered. This means that the reinforced concrete structure of the refueling water tank may be used for more than 80 years. Boric acid corrosion on reinforced concrete is irreversible and may not have much impact in the short term. However, over time, without assessing or predicting the extent of corrosion, this could lead to a decrease in the bearing capacity of the refueling water tank's reinforced concrete structure, raising questions about whether it meets its safety requirements. Boric acid is rarely used in industry, and therefore, research on it is relatively limited. Existing laboratory tests have simulated the effects of boric acid leakage on reinforced concrete. Test results show that after 70 years of exposure, the reinforced concrete in the spent fuel water tank will deteriorate by approximately 33.0 mm and 11.2 mm. The steel bars will not be corroded because the corrosion depth is less than the thickness of the reinforced concrete protective layer, assuming the reinforced concrete is free of cracks. However, existing corrosion predictions do not consider the impact of reinforced concrete cracks, making the accuracy of corrosion predictions unguaranteed.

[0055] This application provides a solution. After receiving the boric acid solution concentration and reinforced concrete information of the nuclear power plant, a pre-built final prediction model is used to detect the reinforced concrete corrosion information of the nuclear power plant in real time. When the reinforced concrete corrosion information reaches the alarm threshold, an alarm message is generated and sent to the corresponding maintenance management personnel, providing users with better service.

[0056] As can be seen from the above embodiments, the present application receives reinforced concrete information from a nuclear power plant; based on this reinforced concrete information, it uses a pre-constructed final prediction model to detect the corrosion information of the reinforced concrete in the nuclear power plant in real time. When the corrosion information reaches the alarm threshold, an alarm message is generated and sent to the corresponding maintenance personnel. Thus, the pre-constructed final prediction model detects the compressive strength of the reinforced concrete in the nuclear power plant in real time based on the received reinforced concrete information. When the compressive strength reaches the alarm threshold, an alarm message is generated and notified to the corresponding maintenance personnel. This solves the problem of being unable to predict the degree of reinforced concrete corrosion based on the actual use of the nuclear power plant, which can lead to nuclear safety accidents, and improves the accuracy of reinforced concrete corrosion alarms.

[0057] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device capable of implementing the above functions, a reinforced concrete boric acid corrosion alarm device, etc. The following uses the reinforced concrete boric acid corrosion alarm device as an example to illustrate this embodiment and the following embodiments.

[0058] Based on this, the embodiment of the present application provides a reinforced concrete boric acid corrosion alarm method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the reinforced concrete boric acid corrosion alarm method of the present application.

[0059] In this embodiment, the reinforced concrete boric acid corrosion alarm method includes steps S01 to S06:

[0060] Step S01, receiving reinforced concrete information of a nuclear power plant;

[0061] Before explaining the present embodiment, it should be understood that the present embodiment is directed to the reinforced concrete of a nuclear power plant. During operation of the nuclear power plant, boron-containing water is generally used to control the seed flux density. Therefore, boric acid solution is present in the spent fuel pool and refueling water tank in the nuclear power plant. Due to defects in the bottom plate welds of the steel lining of the refueling water tank, leakage of the refueling water tank is likely to occur, which directly causes the boric acid solution to enter the reinforced concrete structure of the refueling water tank, thereby causing corrosion of the reinforced concrete.

[0062] In existing nuclear power plants, the design life is generally 60 years. However, the corrosion of reinforced concrete by boric acid is irreversible and may not have much impact in the short term. However, as time goes by, if the degree of corrosion of reinforced concrete is not judged or predicted, it may lead to a decrease in the bearing capacity of the reinforced concrete structure of the refueling water tank, resulting in safety accidents.

[0063] Therefore, in this embodiment, the reinforced concrete information of the nuclear power plant is received, wherein the nuclear power plant here should include information on the concentration of the boric acid solution and reinforced concrete information. It can be analyzed as a new nuclear power plant, or it can be a nuclear power plant that has been put into use for a period of time. The reinforced concrete information mainly includes the materials used, the length of use, and the material ratio.

[0064] Step S06: Based on the reinforced concrete information, the reinforced concrete corrosion information of the nuclear power plant is detected in real time through a pre-built final prediction model. When the reinforced concrete corrosion information reaches an alarm threshold, an alarm message is generated and sent to the corresponding maintenance management personnel.

[0065] After the final prediction model is constructed in advance, the nuclear power plant can be inspected in real time through the final prediction model, mainly to detect the corrosion information of the reinforced concrete of the nuclear power plant and check whether the corrosion situation affects the safety of the refueling water tank of the nuclear power plant. When the corrosion information of the reinforced concrete is detected to reach the alarm threshold, an alarm message is generated based on the actual compressive strength and sent to the corresponding maintenance management personnel to improve efficiency and prevent risks.

[0066] It should be clear that after a nuclear power plant is put into operation, a model can be constructed to predict the use of the nuclear power plant. Specifically, before the step S06 of detecting the steel and concrete corrosion information of the nuclear power plant in real time using the pre-constructed final prediction model based on the steel and concrete information, the method further includes:

[0067] Step S02, receiving nuclear power plant design standard information;

[0068] Step S03, parsing the nuclear power plant design standard information to obtain an exemplary boric acid solution temperature set, an exemplary boric acid solution concentration set, and exemplary reinforced concrete information;

[0069] Step S04, generating a plurality of experimental reinforced concrete structures based on the exemplary reinforced concrete information;

[0070] Step S05 , constructing a final prediction model using the exemplary boric acid solution temperature set, the exemplary boric acid solution concentration set, and several experimental reinforced concrete structures.

[0071] In order to make the prediction model more compatible with actual nuclear power plants, the nuclear power plant design standard information received in this embodiment includes an exemplary boric acid solution temperature set, an exemplary boric acid solution concentration set, and exemplary reinforced concrete information. The exemplary reinforced concrete information includes reinforced concrete with multiple materials and multiple proportions. Therefore, in this embodiment, several experimental reinforced concrete structures are first generated based on the exemplary reinforced concrete information.

[0072] Then, the exemplary boric acid solution temperature set and the exemplary boric acid solution concentration set can be used to conduct experiments on several experimental reinforced concrete structures and record the results to obtain the compressive strength of the reinforced concrete, and thus construct an initial prediction model.

[0073] More specifically, the step S05 of constructing a final prediction model using the exemplary boric acid solution temperature set, the exemplary boric acid solution concentration set, and several experimental reinforced concrete structures includes:

[0074] Step S051, performing strength tests on the plurality of experimental reinforced concrete structures using the exemplary boric acid solution temperature set and the exemplary boric acid solution concentration set to obtain a first analysis result;

[0075] Step S052, performing microscopic inspection on the plurality of experimental reinforced concrete structures using the exemplary boric acid solution temperature set and the exemplary boric acid solution concentration set to obtain a second analysis result;

[0076] Step S053: construct a final prediction model based on the first analysis result and the second analysis result.

[0077] Specifically, the several experimental reinforced concrete structures include a first experimental reinforced concrete structure, a second experimental reinforced concrete structure, and a third experimental reinforced concrete structure. In order to test the compressive strength at different boric acid solution concentrations, the step S051 of performing strength tests on the several experimental reinforced concrete structures using the exemplary boric acid solution temperature set and the exemplary boric acid solution concentration set to obtain a first analysis result includes:

[0078] Step S0511, selecting a first boric acid solution concentration based on the exemplary boric acid solution concentration set;

[0079] Step S0512: Immersing the first experimental reinforced concrete structure, the second experimental reinforced concrete structure, and the third experimental reinforced concrete structure respectively in the first boric acid solution concentration, and adjusting the temperature of the immersion solutions of the first experimental reinforced concrete structure, the second experimental reinforced concrete structure, and the third experimental reinforced concrete structure based on the exemplary boric acid solution temperature set, to obtain the first experimental reinforced concrete structure, the second experimental reinforced concrete structure, and the third experimental reinforced concrete structure that have been immersed;

[0080] Step S0513, detecting the compressive strength of the immersed first, second, and third reinforced concrete structures to obtain a first, second, and third compressive strength.

[0081] Step S0514: performing a summary analysis on the first compressive strength, the second compressive strength, and the third compressive strength to obtain a first analysis result.

[0082] In the experimental reinforced concrete structure of this embodiment, different crack widths are set. The test sets three crack widths, namely 0.3 mm, 0.6 mm and 1.0 mm. Subsequently, three boric acid concentrations are preset for the compressive strength of reinforced concrete, namely 0.27%, 3% and 4.5%, respectively. Three test temperatures are preset, namely 20°C, 55°C and 70°C, respectively. After 28 days of standard curing, the test is conducted on specimens of different sizes (experimental reinforced concrete structures). The first analysis results, namely the compressive strength of the experimental reinforced concrete structure at different temperatures, different crack widths and different concentrations, are obtained. The compressive strength of reinforced concrete at 3% boric acid concentration at different temperatures and different ages is shown in Table 1:

[0083]

[0084]

[0085] Table 1

[0086] As can be seen from Table 1, under the condition of immersion in 3% boric acid concentration, with the increase of immersion temperature (20℃, 55℃, 70℃), the compressive strength of each immersion age shows a trend of first increasing and then decreasing, indicating that under the condition of 3% boric acid concentration, the immersion temperature (70℃) is not conducive to the compressive strength, which is consistent with the microscopic test results of reinforced concrete.

[0087] In this embodiment, SEM electron microscopy and mercury intrusion porosimetry can be used to analyze the reinforced concrete results to obtain the microstructure and porosity of the reinforced concrete. The SEM electron microscopy results of the reinforced concrete at different temperatures (20°C, 55°C and 70°C) at 30 days, 60 days and 120 days under the condition of 3% boric acid concentration are as follows: Figure 2 As shown in the figure, when the boric acid concentration is 3% and the immersion temperature is 70℃, obvious microcracks can be observed in the reinforced concrete. At the same time, the microstructure of the reinforced concrete becomes looser and many holes are generated. The generation of microcracks and the looseness of the microstructure will lead to a decrease in the mechanical properties of the reinforced concrete material.

[0088] The above-mentioned first analysis result is analyzed based on the temperature change. In order to understand the compressive strength of reinforced concrete under concentration changes, this embodiment uses the fourth experimental reinforced concrete structure, the fifth experimental reinforced concrete structure, and the sixth experimental reinforced concrete structure to further analyze the micromorphology and porosity of reinforced concrete under different temperatures and different ages, and obtains the second analysis result.

[0089] Therefore, in step S052, the step of performing microscopic inspection on the plurality of experimental reinforced concrete structures using the exemplary boric acid solution temperature set and the exemplary boric acid solution concentration set to obtain the second analysis result includes:

[0090] Step S0521, selecting a first boric acid solution temperature based on the exemplary boric acid solution temperature set;

[0091] Step S0522: immersing the fourth experimental reinforced concrete structure, the fifth experimental reinforced concrete structure, and the sixth experimental reinforced concrete structure in the first boric acid solution temperature distribution, and adjusting the concentration of the immersion solution for the fourth experimental reinforced concrete structure, the fifth experimental reinforced concrete structure, and the sixth experimental reinforced concrete structure based on the exemplary boric acid solution concentration set, to obtain the fourth experimental reinforced concrete structure, the fifth experimental reinforced concrete structure, and the sixth experimental reinforced concrete structure after immersion;

[0092] Step S0523, performing microscopic analysis on the immersed fourth experimental reinforced concrete structure, the fifth experimental reinforced concrete structure, and the sixth experimental reinforced concrete structure using a scanning electron microscope and mercury intrusion porosimetry to obtain first corrosion data, second corrosion data, and third corrosion data;

[0093] Step S0524: Summarize and analyze the first corrosion data, the second corrosion data, and the third corrosion data to obtain a second analysis result.

[0094] At a temperature of 55°C, the compressive strength of reinforced concrete of different concentrations and ages is shown in Table 2:

[0095]

[0096] Table 2

[0097] As can be seen from Table 2, under the condition of immersion at a temperature of 55°C, with the increase of immersion concentration (0.27%, 3%, 4.5%), the compressive strength of each immersion age basically did not show a significant downward trend, indicating that different immersion concentrations have little effect on the compressive strength. Similarly, the results of reinforced concrete can be analyzed by SEM electron microscope scanning and mercury intrusion method. The porosity results of reinforced concrete tested by mercury intrusion method are similar to this. Figure 3 The changes in the porosity of reinforced concrete under different corrosion solution concentrations are given. It can be seen that in a corrosion solution environment at 55°C, the porosity of reinforced concrete corroded for 30 days and 120 days (except for the data point of 4.5% corrosion solution at 30 days) does not change much with the increase of corrosion solution concentration, while the porosity of reinforced concrete corroded for 60 days increases by less than 20% with the increase of corrosion solution concentration. Overall, the corrosion solution concentration has little effect on the porosity of reinforced concrete.

[0098] After obtaining the first and second analysis results mentioned above, the model is constructed by combining a large number of data and analysis results. Since different immersion concentrations have little effect on the compressive strength, it is necessary to establish a calculation model for the compressive strength (fc) of reinforced concrete under the influence of temperature (T, ℃) and age (t, d). By fitting the test data in Table 1, the following can be obtained: Figure 4 The calculation model of the compressive strength (fc) of reinforced concrete is shown in FIG. 1 . It can be seen that the calculation model of the compressive strength (fc) of reinforced concrete considering the influence of temperature (T, °C) and age (t, d) at a concentration of 3% boric acid can be expressed as formula (1) (R2 = 0.88):

[0099] fc=-0.01T 2 +0.9T+0.18ln(t)+39.74

[0100] According to the above formula (1), the compressive strength fc(0) of crack-free reinforced concrete at the age of 30 days and the temperature of 20°C is calculated to be 53.3 MPa. The relationship between the ratio of the compressive strength of crack-free reinforced concrete (ages 30 days, 60 days, and 120 days) at the temperature of 20°C to fc(0) and the porosity (φ) obtained by mercury intrusion testing can be expressed as formula (2):

[0101]

[0102] As shown in Table 4,

[0103]

[0104] Table 4

[0105] The above formula (2) can express the fitting relationship between compressive strength and porosity. At the same time, at a temperature of 55°C, the relationship between crack width (w, mm) and porosity (φ) can be expressed by formula (3):

[0106]

[0107] As shown in Table 5:

[0108]

[0109] Table 5

[0110] Finally, the calculation model of reinforced concrete compressive strength (fc) considering the effects of temperature (T, °C), age (t, d), and crack width (w, mm) can be expressed as:

[0111] fc=e-0.1w(-0.012T 2 +T+0.2ln(t)+37.45)

[0112] This embodiment, through the above-mentioned solution, specifically receives reinforced concrete information from a nuclear power plant; based on this reinforced concrete information, uses a pre-built final prediction model to monitor the corrosion of the reinforced concrete in real time. When the corrosion reaches an alarm threshold, an alarm is generated and sent to the corresponding maintenance personnel. Thus, the pre-built final prediction model monitors the compressive strength of the reinforced concrete in the nuclear power plant in real time based on the received reinforced concrete information. When the compressive strength reaches the alarm threshold, an alarm is generated and notified to the corresponding maintenance personnel. This solves the problem of being unable to predict the degree of reinforced concrete corrosion based on the actual use of the nuclear power plant, which can lead to nuclear safety accidents, and improves the accuracy of reinforced concrete corrosion alarms.

[0113] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above embodiment 1 can be referred to the above introduction and will not be described in detail later. Figure 5 Step S06, based on the reinforced concrete information, uses a pre-built final prediction model to detect the reinforced concrete corrosion information of the nuclear power plant in real time, including steps S061 to S062:

[0115] Step S062: Based on the environmental information, the final prediction model is used to predict and obtain the reinforced concrete corrosion information of the nuclear power plant. The reinforced concrete corrosion information includes the degree of reinforced concrete corrosion and the corrosion trend.

[0116] After understanding the model used and how it was constructed, we can conduct tests on actual nuclear power plants:

[0117] First, based on the pre-set environment collection nodes (fixed time can be set for management personnel, such as T0, T0+30, T0+60 and T0+90), corresponding information collection is performed to obtain environmental information;

[0118] Subsequently, the environmental information is input into the final prediction model to predict the reinforced concrete corrosion information of the nuclear power plant (including the degree of reinforced concrete corrosion and corrosion trend);

[0119] Finally, in this embodiment, an alarm threshold is also established, which can be used to issue a corresponding alarm when the corrosion trend changes significantly faster or the corrosion degree of reinforced concrete exceeds 70%, so that maintenance managers can be informed and take corresponding measures.

[0120] This embodiment, through the above-mentioned solution, specifically collects environmental information through pre-set environmental collection nodes. Based on this environmental information, the final prediction model is used to predict the nuclear power plant's reinforced concrete corrosion information, including the degree of corrosion and corrosion trend. Consequently, the pre-built final prediction model uses the received information to perform real-time monitoring of the plant's reinforced concrete compressive strength. When the compressive strength reaches an alarm threshold, an alarm is generated and notified to the corresponding maintenance personnel. This solves the problem of failing to predict the degree of reinforced concrete corrosion based on actual nuclear power plant usage, which can lead to nuclear safety accidents, and improves the accuracy of reinforced concrete corrosion alarms.
