Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure.
The following describes a method, an apparatus and an electronic device for determining a nuclear power production work risk level according to an embodiment of the present disclosure with reference to the drawings. The method for determining the nuclear power production working risk level according to the embodiment of the disclosure can be executed by the device for determining the nuclear power production working risk level provided by the embodiment of the disclosure, and the device can be configured in electronic equipment.
For convenience of description, the device for determining the nuclear power production work risk level may be referred to as a "determining device".
Fig. 1 is a schematic flow chart of a method for determining a nuclear power production operational risk level according to an embodiment of the present disclosure. As shown in fig. 1, the method for determining the nuclear power production working risk level may include the following steps:
step 101, obtaining a nuclear power production work order, wherein the nuclear power production work order comprises first data of nuclear power production work.
Generally, after a nuclear power plant enters a production operation stage, in order to guarantee the operation safety of the nuclear power plant, risk identification is required for each production operation. Therefore, in the embodiment of the disclosure, the risk level corresponding to the nuclear power production work can be obtained by processing the received nuclear power production work order, so that measures can be taken in time to deal with possible risks.
The nuclear power production work order can be a work order containing first data of nuclear power production work, and can be generated according to input parameters; or the work order can be generated according to the initial value or the default value; etc., which the present disclosure is not limited to.
In addition, the first data of the nuclear power production work may be nuclear power production work data determined by analyzing the current operation condition of the nuclear power plant, and may be equipment data, maintenance work data, and the like. The present disclosure is not limited thereto.
It can be understood that the nuclear power production work order can be obtained spontaneously according to a preset period; or, a nuclear power production work order and the like may also be obtained under the condition that the touch operation is monitored, which is not limited by the disclosure.
And 102, processing the first data of the nuclear power production work to determine a corresponding first reference risk level in the work order.
The method comprises the steps of analyzing and processing first data of nuclear power production work, and determining a work type and a title description corresponding to the production work.
The type of work may be non-preventive maintenance work or may also be preventive maintenance work, among others. Further, non-preventive maintenance work can be further divided into: fault repair (CM), minor defect repair (DM), other repair (OM), change (MD), Support (SA). Preventive maintenance work can also be divided into: periodic testing in preventive maintenance work and non-periodic testing in preventive maintenance work. The present disclosure is not limited thereto.
It can be understood that the information of the work type, the equipment classification in the work object, the nuclear safety level, the key sensitive area, the technical specification and the like can be determined by processing the first data of the nuclear power production work contained in the work order.
Optionally, the work type in the work order may be determined by processing the first data of the nuclear power production work.
For example, by processing the first data of the nuclear power production work and determining that the data contains "CM", the work type can be determined to be "failure handling"; or, if it is determined that the first data of the nuclear power production work finally includes "DM", the work order type may be determined to be "minor defect repair", and the like, which is not limited by the present disclosure.
And then, determining the value of the first field corresponding to the work type according to the work type in the work order.
It will be appreciated that the corresponding first field may be the same or may be different for different job types. In addition, the same work type, corresponding to the first field, may be one or multiple, and this disclosure does not limit this.
For example, for a periodic test in preventive maintenance work, the corresponding first field may be "limit conditions for operation of the technical specifications (LCO) defense clearing time"; for non-preventive maintenance work, the corresponding first field may be "equipment classification", "disassembly and maintenance", and the like, which is not limited by the present disclosure.
Then, a first risk score may be determined according to a value of the first field.
Wherein for non-preventive risk work, the corresponding first risk score may be determined using the following equation (1):
Figure BDA0003359887130000041
wherein, U1The first risk score is n, the item number of the element weighting score influencing the production work risk level is n, the element weighting score influencing the production work risk level is w, the risk factor score under the element category influencing the production work risk level is z, the lambda is a coefficient representing the work proficiency, and the K is a coefficient representing the work complexity.
Wherein, for the different parameters, corresponding value ranges can be set. For example, the parameter w may take the following values: 1-10. It can be understood that the larger the weighting of the elements affecting the production work risk level, the larger the value of w, for example, may be 8, 9, etc.; the smaller the element weight, the smaller the value of w, which may be, for example, 1, 2, etc. The present disclosure is not limited thereto.
Alternatively, the value of the parameter z may be set as follows: 1-10. It can be understood that the more risk factors, the larger the value of z; the fewer risk factors, the smaller the value of z; if there is no risk factor partition under this category, the value of z may be 1. The present disclosure is not limited thereto.
Alternatively, the value of the parameter λ may be set in advance as follows: 0.7-1. It will be appreciated that a lower parameter λ indicates a higher level of work proficiency. The present disclosure is not limited thereto.
Alternatively, the value of the parameter K may be: 0.6-1. It will be appreciated that a lower parameter K indicates a higher complexity of operation.
It should be understood that the value ranges of the above parameters can be determined according to technical specifications, related technical data, etc., and the specific numerical values of the above numbers can be determined according to the work types and the work descriptions, etc., which are not limited in this disclosure.
For example, if the work type is "CM", the corresponding device hierarchy may be "CC 2", and the corresponding parameter value may be w1、w2、z1、z2(ii) a Or, if the work type is "DM", the corresponding device classification may be "CC 1", and the corresponding parameter value may be w3、w4、w5、z3、z4、z5And so on.
It should be noted that the foregoing examples are merely illustrative, and cannot be used as limitations on the types of operations, values of parameters, and the like in the embodiments of the present disclosure.
And then, determining a first reference risk level of the nuclear power production work according to the relation between the preset risk score and the risk level.
It is understood that the higher the risk level, the lower its corresponding risk score; the lower the risk rating, the higher its corresponding risk score.
For example, for non-preventive maintenance work, the relationship between the corresponding risk score and risk level can be divided as follows: high risk: u shape1Less than or equal to 70; the risk: 70<U1Less than or equal to 80; low risk: u shape1>80。
It should be noted that the above examples are only illustrative, and should not be taken as limiting the relationship between the risk score and the risk level in the embodiments of the present disclosure.
For example, the first risk score is determined to be 75 by using the above formula (1), and the first reference risk level can be determined to be "medium risk" according to the relationship between the preset risk score and the risk level. The present disclosure is not limited thereto.
Optionally, the work types in the work order are: in the case of a periodic test in preventive maintenance work, and the first field is "LCO defense retreat time", it may be set in advance: LCO defense quitting time is less than or equal to 8 hours, and the corresponding risk grade is high risk; the LCO defense quitting time is more than 8 hours and less than or equal to 24 hours, and the corresponding risk grade is medium risk; LCO defense quitting time is more than 8 hours, and the corresponding risk grade is low risk. If the first data of the nuclear power production work contains 'LCO defense-quitting time 12 hours', the value of the first field 'LCO defense-quitting time' can be determined as follows: 12 hours, so that the first reference risk level can be determined as "intermediate risk".
It should be noted that the above example is only an illustrative example, and cannot be taken as a limitation on the values of the first field and the first field, the first reference risk level, the first risk score, and the like in the embodiment of the present disclosure.
For example, if the work type is "non-periodic test work in preventive maintenance", and the work order includes at least one of "shutdown and shutdown", "unit transient", and "heavy water leakage", it may be determined that the corresponding risk level may be high risk; if the work order contains "major equipment damage," it can be determined to be a medium risk.
It should be noted that the above examples are only illustrative, and should not be taken as limitations on the type of work, the target risk level, and the like in the embodiments of the present disclosure.
And 103, determining the value of the designated field according to the received second data of the nuclear power production work.
It can be understood that the first data of the nuclear power production operation may be initial data of each device and each system in the nuclear power plant, and after the work preparation is performed, the risk level of the nuclear power production operation may be further determined according to the received second data of the nuclear power production operation after the scheduled date is determined.
The second data of the nuclear power production work may be data of equipment, systems, administrative licenses and the like in the nuclear power plant after the preparation work is completed, and may be production data different from the first data of the nuclear power production work.
For example, by processing the second data of the nuclear power production work, it is determined that the corresponding work type is "non-periodic test in preventive maintenance work", and the number of the corresponding designated fields may be one or multiple, which is not limited in this disclosure.
For example, the designated field may be "core damage frequency", or may also be "Technical Specification (TS) defense clearing time", or may also be "operational risk analysis", or may also be "work permit", etc., which is not limited by the present disclosure.
For example, if the designated field is "TS defense clearing time", and it is determined that "TS defense clearing time 2 hours" is included in the second data of the nuclear power production work, the value of the designated field "TS defense clearing time" may be determined as follows: for 2 hours.
Or, the designated field is a "work license", and if it is determined that the nuclear power production work second data includes a "level 1 radiation work license", it may be determined that the value of the designated field "work license" is: and the grade 1 radiation work permits.
It should be noted that the above examples are merely illustrative, and cannot be taken as limitations on the designated fields and values of the designated fields in the embodiments of the present disclosure.
And 104, determining a second reference risk level corresponding to the value of the designated field according to the relation between the preset field value and the risk level.
It can be understood that the relationship between the field value and the risk level can be set in advance, and then after the value of the designated field is determined according to the second data of the nuclear power production work, the second reference risk level corresponding to the designated field value can be determined by searching the relationship between the preset field value and the risk level.
For example, when the operation type is "non-periodic test in preventive maintenance work", and the designated field is "core damage frequency", it may be set that when the core damage frequency value is in the yellow zone range, the corresponding risk level is medium risk; and when the core damage frequency value is within the red zone range, the corresponding risk level is high risk. Wherein, the red zone and the yellow zone range are set in advance. If the value of the core damage frequency in the second data is determined to be a and is within the range of the set red zone [ b, c ], the second reference risk level can be determined to be "high risk".
Optionally, if it is determined that the value of the "work license" is: the work with 1 level of risk and the work with 1 level of fire can be determined as the work with medium risk; if the value of the work license is determined as follows: and 2, level 2 high risk work, level 1 fire work and level 3 fire work can be determined as an element influencing the risk level of the production work, namely the low risk level.
Or, if the value of the administrative license is determined to be: if the grade 1 radiation work is permitted, the high-risk work can be determined; if the value of the administrative license is determined as follows: if the level 2 radiation work permission and the level 3 radiation work permission are adopted, the medium risk work can be determined; if the value of the administrative license is determined as follows: the permission of 4-level radiation work can be determined as an element influencing the risk level of production work.
Or, if the value of the administrative license is determined to be: a radiographic inspection permit, it can be determined to be a high risk job.
Or, if the value of the 'administrative license' is determined to be any one of the following items: and determining that the fire barrier opening permission (FHP), the flammable and combustible permission (YR), the fire hydrant use permission (XS) and the physical protection system function can be used as an element influencing the production work risk level.
It should be noted that the above examples are merely illustrative, and cannot be taken as limitations on values of specified fields, corresponding risk levels, and the like in the embodiments of the present disclosure.
And 105, determining a target risk level of nuclear power production work according to the first reference risk level and the second reference risk level.
It is understood that in order to ensure the safety of the operation of the nuclear power plant, a higher risk level may be determined as a target risk level for the nuclear power production work.
For example, if the first reference risk level is a low risk and the second reference risk level is a high risk, the target risk level of the nuclear power production operation may be determined to be a high risk. Or, if the first reference risk level is medium risk and the second reference risk level is low risk, the target risk level of the nuclear power production work may be determined to be medium risk.
It should be noted that the above examples are only illustrative, and cannot be taken as a limitation on the manner of determining the target risk level of nuclear power production operation and the like in the embodiments of the present disclosure.
According to the embodiment of the disclosure, a nuclear power production work order can be obtained first, wherein the work order comprises first data of nuclear power production work, then the first data of the nuclear power production work is processed to determine a first reference risk level corresponding to the work order, then a value of a designated field is determined according to received second data of the nuclear power production work, then a second reference risk level corresponding to the value of the designated field can be determined according to a relation between a preset field value and a risk level, and then a target risk level of the nuclear power production work is determined according to the first risk level and the second risk level. Therefore, the nuclear power production work risk grade can be determined by analyzing and processing the first data and the second data in the nuclear power production work order and combining the relationship between the field and the risk grade, the dependence on the operation experience of power plant personnel is reduced, the accuracy of determining the target risk grade is improved, the labor cost for determining the nuclear power production work risk grade is reduced, the efficiency is improved, and the time is saved.
Fig. 2 is a schematic flow chart of a method for determining a nuclear power production operational risk level according to an embodiment of the present disclosure.
As shown in fig. 2, the method for determining the nuclear power production working risk level may include the following steps:
step 201, obtaining a nuclear power production work order, wherein the nuclear power production work order comprises first data of nuclear power production work.
Step 202, processing the first data of the nuclear power production work to determine the work type in the work order.
And 203, determining the value of the first field corresponding to the work type according to the work type in the work order.
And 204, determining a first risk score and a first reference risk grade according to the value of the first field.
Optionally, under the condition that the first reference risk level is determined, the first reference risk level may be displayed, and the first reference risk level may also be sent to the target staff, so that the target staff may perform processes such as work approval based on the first reference risk level.
For example, the first reference risk level is "medium risk", and the corresponding indicator light can be controlled to flash yellow light; alternatively, if the first reference risk level is "low risk", the corresponding indicator light may be controlled to flash green light, and so on.
It should be noted that the above examples are merely illustrative, and are not intended to limit the manner in which the target risk level is presented in the embodiments of the present disclosure.
The target staff may be a corresponding service staff, or may also be an on-duty staff, or may also be a staff of nuclear power production work, and the like, which is not limited in this disclosure.
It is to be understood that the determined target risk level may be sent to the target staff member in any desirable manner, such as in a mail form, an information push form, and the like, which is not limited by the present disclosure.
And step 205, determining the value of the designated field according to the received second data of the nuclear power production work.
Optionally, the second data of the nuclear power production work can be determined and received through a preset time length under the condition of obtaining the nuclear power production work order.
The preset time period may be a time period set in advance, for example, may be 1 day, 2 days, 12 hours, and the like, which is not limited in this disclosure.
It is understood that after the first reference risk level is determined, preparation work for operation of the nuclear power plant, such as risk analysis, countermeasure, isolation requirement, and the like, may be performed for a preset time period, so that it may be determined to receive the second data of the nuclear power production work after the preset time period elapses.
For example, the preset time is 24 hours, so that after the nuclear power production work order is obtained, the second data of the nuclear power production work can be determined to be received after 24 hours, and the like.
Or, in response to the touch operation, determining to receive second data of nuclear power production work.
The touch operation may be triggered manually, for example, clicking, selecting, sliding, and the like, which is not limited in this disclosure.
For example, when the 'click' operation is monitored, it can be determined that a new nuclear power production work order is generated, and thus the nuclear power production work order can be received. The present disclosure is not limited thereto.
And step 206, determining a second reference risk level corresponding to the value of the designated field according to the relationship between the preset field value and the risk level.
And step 207, determining a second risk score according to the value of the designated field and the second reference risk level.
Wherein corresponding risk scores may be set for different reference risk levels.
It will be appreciated that the corresponding risk score ranges are different for different risk levels; under the condition that the values of the designated fields are in the same risk level, the values of the designated fields are different, and the corresponding second risk scores may also be different. The present disclosure is not limited thereto.
For example, in the case where the operation type is "non-periodic test operation in preventive maintenance", and the specified field is "core damage frequency", if it is set: the value of the damage frequency of the reactor core is [1.0 x 10 ]-4，1.0*10-3]Namely, when the reactor core damage frequency value is in the yellow region, the corresponding risk grade is the medium risk, and the risk score is 70-80; the value of the frequency of the damage frequency of the reactor core is more than 1.0 x 10-3That is, when the value of the core damage frequency is in the red zone, the corresponding risk level is high risk, and the risk score is 70 points or less. If the value of the designated field 'core damage frequency' is determined to be 0.00011, the relation between 0.0011 and 1.0 x 10 can be determined by searching the relationship between the preset field value and the risk grade-4And 1.0 x 10-3Meanwhile, the method can be judged to enter the yellow region, so that the second reference risk level corresponding to the nuclear power production work can be determined as follows: a second risk score of 72 points, or 71 points, etc.
Alternatively, it is also possible to set in advance: LCO defense quitting time is less than or equal to 8 hours, the corresponding risk grade is high risk, and the production risk score is as follows: 70 and below; the LCO defense quitting time is more than 8 hours and less than or equal to 24 hours, the corresponding risk grade is intermediate risk, and the production risk score is as follows: 70-80 minutes; LCO defense quitting time is more than 8 hours, the corresponding risk grade is low risk, and the production risk score is as follows: 80 points or more. If the designated field is the LCO defense quitting time, it is determined that the second data of the nuclear power production work contains the LCO defense quitting time of 12 hours, and according to the relation between the preset designated field value and the production risk score, it can be determined that the second reference risk level is the middle risk, and the corresponding second risk score can be 73, or 74, 75, and the like. The present disclosure is not limited thereto.
Alternatively, it has been set that: the TS defense quitting time utilization rate is more than or equal to 75 percent, the corresponding risk grade is high risk, and the production risk score is as follows: 70 and below; the TS defense quitting time utilization rate is as follows: 50% -75%, corresponding risk grade is medium risk, production risk score is: 70-80 parts; the TS defense quitting time utilization rate is as follows: less than or equal to 50; the corresponding risk rating is: as an element affecting the risk level of the production work, i.e. low risk; the production risk score is: 80 and above.
It is understood that the production risk score may be inversely related to the TS defense time. If the TS defense quitting time in the second data is 2 hours, and the preset planning period is 1.5 hours, the TS defense quitting time utilization rate is 75%, so that the risk level can be determined as high risk, and the production risk score can be 75 points, or 76 points, and the like. If the TS defense quitting time in the second data is 5 hours and the preset planning period is 1 hour, the TS defense quitting time utilization rate is 25%, so that the risk level can be determined to be low risk, and the production risk score can be 85 points, 90 points, or the like.

It can be understood that, for the above-mentioned case that the production work risk level can be directly determined, a corresponding production work risk score can be set for each production work risk level; the present disclosure is not limited thereto.
And step 208, determining the risk grade corresponding to the minimum risk grade in the first risk score and the second risk score as a target risk grade of nuclear power production work.
It can be understood that, if the risk score is smaller and the production risk faced by the risk score is likely to be larger, the risk grade corresponding to the minimum value in the risk score may be determined as the target risk grade of the nuclear power production work.
For example, a first risk score of 60, with its corresponding risk rating of high risk; a second risk score of 85, with a corresponding risk rating of low risk; the high risk level corresponding to the first risk score 60 may be determined as the target risk level for the nuclear power production operation.
It should be noted that the above examples are merely illustrative, and should not be taken as limitations on the target production risk scores and their corresponding risk levels in the embodiments of the present disclosure.
Alternatively, the production job risk score may be determined using the following equation (2):
Figure BDA0003359887130000081
wherein, U1The parameters in (1) are the same as those in (U)μProduction job risk score, mu, which is a high risk job in preventive maintenance jobsiA certain risk meets the judgment condition of entering high risk; u shapeφIs a production job risk score, phi, corresponding to risk jobs in preventive maintenance jobsiIs a condition for determining that a certain risk meets the risk in entry.
For example, if U1Corresponding risk score of 90, risk grade of low risk, UμCorresponding risk score of 60, risk grade of high risk, UφThe corresponding risk score is 78 and the risk level is medium risk, then the "high risk" level corresponding to "60" may be determined as the target risk level for the nuclear power production job.
It should be noted that the above examples are only illustrative, and cannot be taken as a limitation on the manner of determining the risk level of nuclear power production operation in the embodiments of the present disclosure.

For example, the first reference risk level is "low risk", the set second field is "core damage frequency", and if the second data of the nuclear power production operation is analyzed and processed to determine that the second data does not include the relevant content of the "core damage probability", the target risk level of the nuclear power production operation can be determined to be "low risk" corresponding to the first reference risk level.
It should be noted that the above examples are only illustrative, and cannot be taken as a limitation on the manner of determining the target risk level of nuclear power production operation and the like in the embodiments of the present disclosure.
