Description

[Technical field]

[0001] An embodiment of the present invention relates to a technology for supporting corrective action activities for non-conformance events or problems that may affect safety. [Background technology]

[0002] At nuclear facilities, safety-related quality assurance activities are carried out based on various rules described in quality management documents. Corrective action programs (CAPs) are then implemented to identify non-conformities that do not meet the requirements of these rules and problems that may affect safety, and a system is established to ensure that these are corrected.

[0003] This CAP activity starts with personnel working at nuclear facilities pointing out on-site conditions that they notice are not as they should be in a condition report (CR). This CR can be submitted by all personnel working at the facility (including contractors), and its purpose is to widely collect all findings obtained through the activities of these personnel.

[0004] Each submitted CR is screened to classify the described conditions based on the significance of the risks they may pose in the future. The significance is determined based on whether the condition is one that affects quality (nuclear safety performance) (CAQ: Condition Adverse to Quality) or one that does not have such an impact (Non-CAQ).

[0005] CRs classified as CAQ are transferred to corrective action management, and the department responsible for dealing with the identified on-site conditions is selected, after which the plan and progress of the measures are followed up as part of the CAP activities. On the other hand, CRs classified as Non-CAQ are excluded from CAP activities, although the cause of the problem is identified and improvements are made as necessary.

[0006] [Patent Document 1] Patent No. 6672514 Summary of the Invention [Problem to be solved by the invention]

[0007] As CAP activities become more active, the number of submitted condition reports (CRs) has increased significantly, including not only nonconformity information, but also findings, audit and patrol observations, information from contractors, etc. As part of these CAP activities, the large number of collected condition reports (CRs) are statistically processed and the results are displayed in graphs to analyze and understand the status of nuclear facilities.

[0008] In order to change the perspective of such analysis and enrich the discussion, there are frequent requests to change the graphs used. However, every time a change is requested, it takes time to recreate the graph, which hinders the progress of the discussion.

[0009] The embodiment of the present invention has been made in consideration of the above circumstances, and aims to provide a technology for supporting corrective action activities that makes it easy to change graphs that display the results of statistical processing of a large amount of collected condition reports (CR).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. Fig. 1 is an overall image diagram of a system 10 to which a support device 20 for corrective action activities (hereinafter, simply referred to as "support device 20") according to an embodiment of the present invention is applied. This system 10 is configured by a management server (support device 20) operated by a business company, a first terminal 11 (11a, 11b, 11c, 11d) of a CR submitter who points out the findings of the on-site condition in a condition report (CR), a second terminal 12 of a screening department that classifies each submitted condition report CR based on importance, and a third terminal 13 of a department in charge of processing a condition report CR that is determined to require corrective action (classified as CAQ) in this classification, all of which are connected to a communication network 15.

[0014] Here, the management server (support device 20), the second terminal 12 of the screening department, and the third terminal 13 of the treatment department are managed by the business company. The first terminals 11 (11a, 11b, 11c) of the CR submitters are managed by the cooperating companies A, B, and C, separately from the first terminal 11d managed by the business company.

[0015] Here, the first terminal 11, the second terminal 12, and the third terminal 13 refer to terminals at which a person with authority as a CR submitter, a person with authority for the screening department, and a person with authority for the treatment department have logged in to the management server (support device 20) via the communication network 15. Therefore, the first terminal 11, the second terminal 12, and the third terminal 13 do not mean that there are three physically existing terminals, and there is no limit to the number of terminals as long as a person with the respective authority can log in.

[0016] Corrective action programs (CAPs) implemented at nuclear facilities collect status reports (CRs) from a wide range of personnel engaged in their work. The first terminals 11 of CR submitters are managed not only by the operating company but also by contractors, allowing for a wide range of findings from the field to be collected. This ensures that non-conformities that do not meet the requirements of the various rules described in the quality management documents and problems that may affect safety are picked up without fail and are reliably corrected.

[0017] 2 is a block diagram of the support device 20 according to the embodiment of the present invention. As described above, the support device 20 includes a first transmitting / receiving unit 22a that receives the first information 41 inputted in the slip form 23 (FIG. 3) displayed on the first terminal 11 and stores it in the database 21, a second transmitting / receiving unit 22b that transmits the first information 41 to the second terminal 12, receives the second information 42 inputted in the review form 25a (FIG. 4(A)) displayed on the second terminal 12, links the second information 42 to the first information 41 and stores it in the database 21, and an extraction unit 22c that specifies the input data 54 (FIGS. 3 and 4) included in the first information 41 and the second information 42 linked thereto. The system further comprises an acquisition unit 52 that acquires output conditions 51 (FIG. 5(A)) from the second terminal 12, an extraction unit 53 that extracts first information 41 including input data 54 specified by the extraction conditions 51 and second information 42 linked thereto from among those stored in the database 21, a receiving unit 56 that receives editing conditions 55 for a graph 58 (FIG. 5(A)) from the second terminal 12, and a creation unit 57 that aggregates the first information 41 and the second information 42 linked thereto extracted from the database 21, creates a graph 58 specified by the editing conditions 55, and displays it on the second terminal 12.

[0018] Furthermore, the support device 20 includes a third transmitting / receiving unit 22c that transmits the first information 41 and the second information 42 linked thereto to the third terminal 13, receives the third information 43 entered in the review form 25b (FIG. 4(B)) displayed on the third terminal 13, and further links the third information 43 to store it in the database 21. The extraction condition 51 can also include input data 54 included in the third information 43 as a specified target. The graph creation unit 57 can also create a graph 58 by tallying up the extracted multiple pieces of third information 43.

[0019] The first transceiver unit 22a, the second transceiver unit 22b, and the third transceiver unit 22c are only separated in terms of logical configuration, and in terms of physical configuration, they consist of a transceiver circuit 22 that exchanges data between the support device 20 and the communication network 15.

[0020] The data link unit 29 links the first information 41, second information 42, and third information 43 transmitted from each of the terminals 11, 12, and 13 to the support device 20 via the communication network 15 together so that related pieces of information are stored in the database 21 as a single record.

[0021] Although not shown in the figure, this support device 20 is composed of a CPU that executes an operating system and application programs, a main memory unit consisting of ROM and RAM, an auxiliary memory unit consisting of a hard disk or the like, a communication control unit consisting of a network card or the like, input units such as a keyboard and mouse, and an output unit such as a monitor.

[0022] Each function of the support device 20 is realized by loading a specific software onto the CPU or main memory, operating the communication control unit, input unit, output unit, etc. under the control of the CPU, and reading and writing data from and to the main memory and auxiliary memory. Data required for processing and a database 21 are stored in the main memory and auxiliary memory. Note that, although this database 21 is constructed inside the support device 20 in this embodiment, it may also be constructed in another device on the communication network 15.

[0023] The first terminal 11 of the CR submitter, the second terminal 12 of the screening department, and the third terminal 13 of the treatment department can be general-purpose computers that come standard with a browser capable of browsing sites on a communication network 15 such as the Internet. There are no limitations on the location of each of these terminals 11, 12, and 13, so long as they are in an environment where they can connect to the communication network 15. The IDs and passwords required for authentication when authorized persons log in to the system from the terminals 11, 12, and 13 are registered in advance in the support device 20.

[0024] 3 is an image diagram of the voucher form 23 displayed on the first terminal 11. When an employee of a nuclear facility becomes aware of an appearance that should not be the way it should be during his / her daily activities, he / she accesses the support device 20 from the first terminal 11 (FIG. 2) as a CR submitter. When a first request signal 31 is sent from this first terminal 11, the support device 20 transmits the voucher form 23 to the first terminal 11 and displays it on the display unit. Note that this voucher form 23 may be transmitted to the first terminal 11 via the communication network 15, or may be displayed by software pre-installed in the first terminal 11.

[0025] Then, the CR submitter inputs the first information 41 (status report CR) from the input section (FIG. 2) of the first terminal 11 into the application form 23. Specifically, the first information 41 is a collection of input data 54 such as the "subject," "date of discovery," "reporter," "location of discovery," "temporary action," and "detailed information" of the CR issue, as shown in the application form 23 in FIG.

[0026] The first information 41 can be inputted not only from text data but also from voice data. The "discovery location" can also handle location data from map data of the facility in addition to text data. "Temporary action" is an item in which the CR submitter selects whether the temporary action he or she has noticed is "completed," "incomplete," or "unnecessary." After inputting each item on the application form 23 (FIG. 3) in this way, by pressing the "Apply" button, the first information 41 is transmitted from the first terminal 11 to the first transceiver 22a and stored in the database 21.

[0027] 4(A) and (B) are image diagrams of the review form 25 displayed on the first terminal 11 and the second terminal 12. Note that FIG. 4(A) and FIG. 4(B) show successive images of the review form 25 (25a, 25b). The person in charge of the screening department periodically accesses the support device 20 from the second terminal 12 (FIG. 2). Alternatively, each time new first information 41 is stored in the database 21, a CR acceptance notice (not shown) informing the same may be sent to the second terminal 12.

[0028] When the second request signal 32 (FIG. 2) is sent from the second terminal 12, the review form 25 is transmitted from the support device 20 together with the first information 41 and displayed on the display unit. Note that the review form 25 may be transmitted to the second terminal 12 via the communication network 15, or may be displayed by software pre-installed in the second terminal 12.

[0029] The screening department staff then inputs second information 42 into review form 25a from the input section (FIG. 2) of second terminal 12. Specifically, second information 42 is a collection of input data 54 such as CAQ classification 45, classification code 59, and person in charge 46 shown in review form 25a in FIG. 4(A).

[0030] The items to be entered in CAQ Classification 45 are determined based on whether the CR event is a condition that affects quality (nuclear safety performance) (CAQ: Condition Adverse to Quality) or a condition that does not have such an effect (Non-CAQ). If it is classified as CAQ, the responsible department is further determined in Responsibility 46, and the corrective action measures (plan formulation and progress status) for the CR event are monitored. From the perspective of risk and uncertainty, CAQ classifications can be further divided into "high," "medium," and "low" according to importance. On the other hand, if it is classified as Non-CAQ, no responsible department is determined and it is excluded from CAP activities.

[0031] The input data 54 can be selected from a plurality of items pre-registered in the review form 25. In this embodiment, the classification code 59 has a plurality of items 38 set, such as "process," "event," "cause," "equipment reliability," and "safety culture," and the input data 54 is selected alternatively from a plurality of input values ​​39 pre-registered in each item 38. The input values ​​39 for these items 38 may be specified from the options in this way, or may be characters entered directly.

[0032] Meanwhile, it is possible to perform machine learning on the relationship between the input data 54 of the first information 41 already stored in the database 21 and the second information 42 linked thereto. By using the results of machine learning in this manner, the input data 54 of the corresponding second information 42 can be automatically input into the review form 25a for new first information 41.

[0033] As shown in Fig. 4(A), a similar events list 37 is displayed adjacent to the review form 25a of the second terminal 12. When input data 54 is selected in an item of the review form 25a, first information 41 already stored in the database 21 is searched for and displayed as a list, the first information 41 dealing with similar events. Then, every time new input data 54 is selected in the review form 25a as second information 42, the search is repeated and the content displayed in the similar events list 37 is updated.

[0034] Then, when data is entered into the CAQ classification 45, classification code 59, and person in charge 46 of the review form 25a on the second terminal 12 and the “Register” button is pressed, the second information 42 including this input data 54 is stored in the database 21.

[0035] Returning to Fig. 2, the explanation will be continued. The person in charge of the treatment department periodically accesses the support device 20 from the third terminal 13. When the third request signal 33 is transmitted from the third terminal 13, the identification data of the third terminal 13 included in this third request signal 33 (ID of an authorized person in the treatment department) is compared with the identification data included in the second information 42 (department data 46; Fig. 4(A)). If there are multiple pieces of information that match, the review form 25 is transmitted from the third transmission / reception unit 22c to the third terminal 13 together with the alternatively selected second information 42 and the first information 41 linked thereto, and is displayed on the display unit.

[0036] In addition to being transmitted to the third terminal 13 via the communication network 15, the review form 25 may be displayed by software pre-installed in the third terminal 13. Each time new second information 42 (FIG. 2) is stored in the database 21, a receipt notification (not shown) may be sent to the third terminal 13 of the responsible department data 46 to inform the same.

[0037] Then, the person in charge of the treatment department inputs the third information 43 into the review form 25b from the input section of the third terminal 13. Specifically, this third information 43 is a collection of input data 54 input in the fields of "analysis," "measures," and "deadline" shown in the review form 25b of Fig. 4(B). Note that in the review form 25 displayed on the third terminal 13, input is restricted in the fields of CAQ classification 45, classification code 59, and person in charge 46.

[0038] The "Analysis" field is where the results of an analysis of why a CR event occurred are entered. The "Countermeasures" field is where the formulation of a specific plan to correct the CR event and the progress of the plan are entered. And the "Deadline" field is where the planned completion date of the corrective action is entered. These input data 54 are updated from the third terminal 13 as progress in addressing the CR event progresses over time.

[0039] The second terminal 12 (FIG. 2) can view the third information 43 entered into the review form 25 by the third terminal 13 at any time. The review form 25 has buttons that display multiple stages ("Screening," "Corrective Action," and "Completion") in the status 47 item. Each status 47 stage indicates the progress of a series of CAP activities for a CR-indicated event. These statuses 47 (input data 54) are included in the second information 42 and stored in the database 21.

[0040] The status 47 shown in the figure shows three types of stages: “Screening,” “Corrective Action,” and “Completion,” but there is no limit to the number of stages as long as it is possible to represent the stage-by-stage status from when the first information 41 is accepted to when corrective action is completed.

[0041] Figures 5(A) and 5(B) are image diagrams of the graph creation form 48 displayed on the second terminal 12. Note that Figures 5(A) and 5(B) show successive images of the graph creation form 48. As the CAP activities progress, records consisting of the mutually linked first information 41, second information 42, and third information 43 are accumulated in the database 21 (Figure 2). Then, the large amount of accumulated information 41, 42, and 43 records are statistically processed and the results are displayed on graphs 58 (58a, 58b, 58e, and 58d) to analyze and understand the state of the nuclear facility.

[0042] The extraction condition 51 shown in Fig. 5(A) specifies the input data 54 (Figs. 3 and 4) included in the records of the information 41, 42, and 43. This input data 54 is specified by specifying the items 38 and / or the input values ​​39 of each item 38 included in the voucher form 23 or review form 25. In the graph creation form 48, the extraction condition 51 can be specified by combining "input data" using logical product (AND), logical sum (OR), and negation (NOT). Furthermore, the "data period" in which the records of the information 41, 42, and 43 were created can also be used as the extraction condition 51.

[0043] The editing conditions 55 shown in Fig. 5(A) specify the type of graph 58 (58a, 58b, 58e, 58d) to be created. The types of graph 58 include, for example, bar graphs, line graphs, pie charts, scatter plots, radar charts, and combinations of these. After inputting the extraction conditions 51 and the editing conditions 55, the corresponding graph 58 is displayed by pressing "display" as shown in Fig. 5(B).

[0044] Furthermore, another graph 58 can be displayed by re-inputting at least one of the extraction conditions 51 and the editing conditions 55. In this way, a plurality of graphs 58 (58a, 58b, 58e, 58d) created by changing the input of the extraction conditions 51 and the editing conditions 55 can be displayed side by side in the graph creation form 48.

[0045] Returning to Figure 2, we will continue with the explanation. The acquisition unit 52 acquires extraction conditions 51 that specify input data 54 included in the first information 41 and second information 42 in the graph creation form 48 (FIG. 5(A)) from the second terminal 12 via the communication network.

[0046] The extraction unit 53 accesses the database 21 and extracts records of the first information 41 containing the input data 54 specified in the extraction condition 51 (Figure 5 (A)) and the second information 42 (and the third information 43) linked thereto.

[0047] The receiving unit 56 receives, from the second terminal 12, the editing conditions 55 (FIG. 5(A)) of the graph 58 specified in the graph creation form 48.

[0048] The creation unit 57 compiles records of the first information 41 and the second information 42 (and the third information 43) linked to it extracted from the database 21, creates a graph 58 (Figure 5 (B)) specified in the editing conditions 55, and displays it on the second terminal 12.

[0049] The operation of the method for supporting corrective action activities and the support program for corrective action activities according to the embodiment will be described based on the sequence diagram of Fig. 6 (see Fig. 2 as appropriate). When a CR submitter notices an unacceptable state at the site or the like (S11), the CR submitter inputs first information 41 into a voucher form 23 (Fig. 3) displayed on the first terminal 11. This first information 41 is received by the support device 20 (S12) and stored in the database 21 (S13). Then, this first information 41 is transmitted from the support device 20 to the second terminal 12 (S14).

[0050] In the screening department, the second information 42 is input into the review form 25a (FIG. 4(A)) displayed on the second terminal 12 (S15). Then, this second information 42 is received by the support device 20 (S16) and stored in the database 21 while being linked to the first information 41 (S17). Then, the support device 20 transmits the first information 41 and the second information 42 linked thereto to the third terminal 13 (S18).

[0051] In the treatment department, the third information 43 is inputted (S19) into the review form 25b (FIG. 4(B)) displayed on the third terminal 13. Then, this third information 43 is received by the support device 20 (S20), and is stored in the database 21 while being linked to the first information 41 and the second information 42 (S21).

[0052] In the screening department, input data 54 included in the first information 41 and the second information 42 is specified as extraction conditions 51 in a graph creation form 48 (FIG. 5(A)) displayed on the second terminal 12 (S22). Then, this extraction condition 51 is acquired by the support device 20 (S23). In the support device 20, records of the information 41, 42, and 43 including the input data 54 specified in the extraction condition 51 are extracted from the database 21 (S24). Then, by repeating the flow from (S11) to (S21), records of the information 41, 42, and 43 are accumulated in the database 21.

[0053] Furthermore, in the screening department, editing conditions 55 (FIG. 5(A)) of graph 58 are specified on second terminal 12 (S25). Then, these editing conditions 55 are accepted by support device 20 (S26). Support device 20 aggregates records of information 41, 42, 43 extracted from database 21, creates graph 58 specified by editing conditions 55 (S27), and displays it on second terminal 12 (S28). Then, by repeating the flow from (S22) to (S24) and / or (S25) to (S28), graph 58 (58a, 58b, 58c, 58d) is modified and created (END).

[0054] According to at least one of the embodiments of the corrective action activity support device described above, records of the first information, second information, and third information that are linked to each other are extracted using extraction conditions specified by input data, and a graph is created in accordance with editing conditions, making it easy to change the display graph of the statistical processing results.

[0055] Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, modifications, and combinations can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope of the invention and its equivalents described in the claims, as well as in the scope and spirit of the invention.
