Description

[0001] SYSTEM AND METHOD FOR HUMAN ERROR PROBABILITY CALCULATION OF NUCLEAR GENERATING STATION [0002]

The present invention relates to an apparatus and method for calculating a human error probability, and more particularly, to a method and apparatus for calculating a human error probability by calculating a standard job detail table in which the job content is subdivided, And indirectly estimating the number of times the task is performed based on the result of the calculation, and finally calculating the human error probability.

Until now, many events or experiences in nuclear power plants have revealed that one of the decisive causes of events or accidents in nuclear power plants is human factors.

Human error has been pointed out as one of the biggest single factors affecting the safety of complex large-scale equipment industries such as nuclear power plants and it is very important to reduce the possibility of human errors through Human Reliability Analysis (HRA) .

In this respect, obtaining sufficient and reliable human performance data necessary for HRA performance is one of the preconditions required for securing and improving nuclear safety.

In order to collect reliability data for HRA analysis of a nuclear power plant, it is ideal to collect and analyze human error performance data (number of job performance and number of performance errors) based on actual driving data.

However, it is not easy to collect and utilize operational history-based operational reliability data in a real environment. This is because it is not easy to systematically collect and maintain operation reliability data of power plants.

Therefore, it is general to analyze based on the human performance (driving) data collected through the training in the simulator environment configured the same as the power plant.

Human performance data collected through simulator training are used to calculate Human Error Probability (HEP) through HRA. There are various methods of calculating the human error probability (HEP) using the human performance data. The most widely used method is the number of operation errors observed during the operation of the power plant, To share.

Human error probability (HEP) = number of errors / frequency of job performance

However, in order to apply the above method, there is a problem in that the number of errors observed and the number of tasks performed must be accurately counted. In other words, in order to accurately calculate the HEP, it is necessary to accurately determine the total number of tasks and the number of errors of the operator. If the number of errors observed and the number of tasks performed are not correct, the accuracy of the HEP value decreases greatly.

In general, the determination of the number of errors for the HEP calculation in the simulation environment is relatively accurate by observing the execution failures observed in the relevant job training training histories, while the accurate determination of the denominator job performance counts It is relatively difficult to determine the range and frequency of observations, since all activities performed by the operators should be observed and counted.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the preferred embodiments of the present invention with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.

FIGS. 1A through 1C are diagrams illustrating an example of a standard job detail table and a standard job detail table according to an embodiment of the present invention.

1A is a diagram illustrating an example of a standard job table according to an embodiment of the present invention.

In the present invention, a standard job detail table (Generic_Task_Detail_Table) based on an operation procedure is designed to have a structure as shown in FIG. 1A in order to indirectly estimate job analysis and frequency of job execution.

The operation procedure is recorded in the storage unit 30 together with the standard job detail table in the form of E-0, E-1,

As shown in FIG. 1A, the items of the standard job detail table include,

A step indicating a step level, a step indicating a job step, a SubStep indicating a subordinate job of a job step as a detailed job step, Contesnts indicating a job description, a DemandNumber indicating a number of requirements required for job execution, A TaskType indicating a job type, a SubTaskType indicating a subordinate job type of a job type as a detailed job type, an Operator indicating a responsible operator, a ComponentType indicating a device type, a SystemType indicating a system type, and a RelatedSystem indicating an associated system.

As an example of analyzing the standard job table of FIG. 1A, the subdivided job ID of FIG. 1A is composed of 11 rows, which is divided into 2 job steps (N, R) and 11 detailed jobs .

Actually, there are dozens of operating procedures for one power plant and one procedure consists of fewer than 100 steps. Each step consists of less than 10 sub-tasks.

Therefore, one operating procedure varies depending on the type, but is basically divided into thousands of detailed jobs, which can be identified by their respective IDs.

Assuming that the operator performs the driving task in the order of ID 1 -> 2 -> 3 -> 7 -> 8 in FIG. 1A, the estimation of the number of times of job execution is estimated as follows (the portion indicated by shaded in FIG.

First, the ID corresponding to the driver driving job is divided into unit jobs in FIG. 1A, and the reasoning is shown in FIG. 1B. Here, the Demand Number, Task Type, and Subtask Type of each row include information on the number of job execution times required to actually perform the corresponding step.

(ROI) for the contents 'SF-HS-319' in the case of the ID 7 task is 2 requests (Demand Number 1; 1) It is necessary to carry out one job of Manipulation, which is a detailed job, and one job of Pushbutton, which is a detailed job of MA.

In the case of ID 3, the job is to confirm that RX Trip Breaker and Bypass Breaker have been opened by the Operator (RO) with the total number of job duties 2 (Demand Number 1; 1) Indicator indicates that the job should be performed as a detailed job of the CS (Checking State) job.

The results of classifying and sorting the Task Type, SubTask Type, and the required number of tasks performed by the operator, which are the number of job execution times (9 times), can be summarized as shown in FIG.

Based on the above description, it is possible to indirectly estimate the number of job performances by referring to the experiment contents (job performance history) performed by the operator on the simulator using the standard job detail table in which the job analysis is performed based on the operation procedure It is possible to do.

Knowing the operation procedure information (the symbols given to each hand procedure procedure, etc.), you can know the value of the job execution frequency corresponding to it. If you know only the number of errors, you can easily calculate the human error probability value.

Therefore, the human error probability (HEP) can be calculated by using the number of job errors observed in the simulator experiment and the number of job performance measured in the standard job detail table.

The tables described in the present invention are three standard job detail tables (Generic_Task_Detail_Table), a procedure development list table (Procedure_List_Table), and a job hierarchy table (Generic_Task_Tree_Table).

However, the data tables necessary for performing human reliability analysis (HRA) can be generated more in addition to this essential table.

The three tables can be designed to share information by joining (interlocking) information with each other with GT_ID being a table field item as a Key.

The standard job detail table identifies the job steps of each procedure for the entire procedure of the target plant, and judges whether the procedure of the same step exists in other procedures.

At this time, it is decided on the unique GT_ID which can distinguish all the job steps for the entire emergency procedures of the power plant by giving the Generic_Task_ID (GT_ID) by summarizing the job steps excluding the redundancy for every detail step of each procedure And store it in the DB. The same step items in other procedures can use the same GT_ID.

For example, the procedure (E-1) starts from step number 1 and is divided into 2, 3, and 4 in order, and GT_ID is assigned to each step number. Step 3 of the procedure E-1 If it is the same as the job performed in step 7 of the procedure E-3, it means that GT_ID 88 like GT_ID previously used can be shared and can be uniquely classified in all jobs.

In addition, a new GT_ID can be assigned if it is not already defined.

If the same procedure included in the operation procedure of the various nuclear power plants is assigned to the same GT_ID through the grant of GT_ID, and the standard job detail table of each nuclear power plant is created based on the GT_ID, the calculation of the human error probability of the nuclear power plant System can be applied.

FIG. 1D is a diagram illustrating an example of a procedure development list table according to an embodiment of the present invention.

The procedure development list table is interlocked with the standard job detail table and the job depth structure table and the GT_ID as KEY, and the contents of the procedure stored in the standard job detail table are clearly organized and the connection with the job hierarchy table .

The procedure development table is a field item, which is a unique serial number of a table, a plant name as a power plant name, a planttype as a plant name, a procedurename as a procedure symbol name, a steptype as a step type, a step indicating a job step, And a steptext indicating the steptext.

1E is a diagram illustrating an example of a job hierarchy table according to an embodiment of the present invention.

The job hierarchy table is a table for providing contents of a procedure stored in the standard job detail table as an interface in a tree format, interlocked with standard job detail table and procedure development list table and GT_ID as KEY, A GT_ID identifying a unique job step, a SubStep indicating a subordinate job of a job step as a detailed job step, a GT_ID in a job hierarchy and a Node representing the SubStep, And a parent indicating an upper connection point of the Node in the hierarchical structure.
