Description

[Technical field]

[0001] The present disclosure relates to an incident initial response support system and an incident initial response support method. [Background technology]

[0002] For example, in plant facilities such as nuclear plants, incidents may occur during plant operation, such as troubles occurring on-site or issues pointed out by regulators. Such incidents are recognized by reports from the site where the plant facilities are installed or from the bases for controlling and managing the plant facilities (e.g., the central control room, the inspection room, or the head office / superior, etc.). When an incident is recognized, multiple personnel are summoned to a specific room to consider the initial response to the incident. Currently, such initial response considerations are carried out by collecting information about the incident obtained through communication via telephone, email, etc. from each relevant party and writing it down on a whiteboard, etc.

[0003] For example, Patent Document 1 discloses technology relating to a control system for controlling a controlled object, which can automatically detect incidents based on operation information of the control system and notify an administrator of information regarding how to deal with the detected incident.

[0004] [Patent Document 1] Patent No. 7099352 Summary of the Invention [Problem to be solved by the invention]

[0005] Personnel in charge of the initial response to an incident are generally engaged in other tasks during normal times when no incident has occurred. These personnel are called to a specific room designated to consider the initial response in response to a convening notice delivered when an incident occurs, and grasp the situation of the incident based on information collected in advance. At this time, the timing at which personnel arrive at the room varies depending on the situation of each personnel, so it is not easy to efficiently share information about the incident with personnel who arrive at the room one after another (for example, it is inefficient to repeat the same explanation every time each personnel arrives at the room). In addition, at the stage of considering the initial response to an incident, various information about the incident is mixed up, so it takes time to select useful information from this information and consider the initial response.

[0006] At least one embodiment of the present disclosure has been made in consideration of the above-mentioned circumstances, and aims to provide an incident initial response support system and an incident initial response support method that can efficiently support consideration of an initial response to an incident.

[0011] Hereinafter, some embodiments of the present disclosure will be described with reference to the accompanying drawings. However, the dimensions, materials, shapes, relative arrangements, etc. of the configurations described as the embodiments or shown in the drawings are merely illustrative examples and are not intended to limit the scope of the present disclosure.

[0012] 1 is a diagram showing a schematic diagram of an information transmission path at the time of an incident occurring in a plant facility 1 that is a support target of an incident initial response support system 100 according to at least one embodiment of the present disclosure. The plant facility 1 is, for example, a nuclear power plant facility, and includes a site 2, a central control room 4, an examination room 6, and a remote monitoring base 8.

[0013] Site 2 is the location where the plant body is installed, and incidents (such as troubles that occur at site 2 during plant operation or notices from regulators) can be detected by monitoring the plant body through inspections and patrols by workers. Incidents detected at site 2 can be notified in various ways, including email, telephone (voice), and data (alarms, monitoring data, etc.), via a terminal that can be operated by a worker.

[0014] The central control room 4 (MCR: Main Control Room) is a main control facility for controlling and managing the plant body installed at the site 2. In the central control room 4, the plant body is controlled and managed, and the operating status of the plant body is monitored, thereby making it possible to detect incidents. Incidents detected in the central control room 4 can be notified in various ways, including email, telephone (voice), and data (alarms, monitoring data, etc.), via various devices installed in the central control room 4 or terminals that can be operated by operators working in the central control room 4.

[0015] The audit room 6 is a base for auditing and supervising the plant equipment 1. For example, the audit room 6 is an area corresponding to supervisory ministries and related companies, and is an area for auditing and inspecting the plant equipment 1 (including both auditing and being audited). In the audit room 6, oral (person-to-person) explanations are given using information related to the plant equipment 1 (which may be written or may be data, and may also be presented in the form of paper or screen display, etc.). Comments from the auditing side and observations from the auditee side at this time are digitized and recorded by speech recognition. It is possible to set flags as comments or observations in the recorded data (both automatically and arbitrarily), which makes it possible to detect incidents. Incidents detected in the audit room 6 can be notified in various ways, including, for example, email, telephone (voice), and data (alarms, monitoring data, etc.) of the information obtained in the audit room 6.

[0016] The remote monitoring base 8 is a base for remotely monitoring the operating state of the plant main body installed at the site 2, at a remote location away from the site 2. A monitoring server (not shown) for monitoring the operating state of the plant main body is installed at the remote monitoring base 8, and the plant main body is remotely monitored by the monitoring server. An incident detected at the remote monitoring base 8 can be notified in various ways, including email, telephone (voice), and data (alarms, monitoring data, etc.), by, for example, the monitoring server installed at the remote monitoring base 8 or a monitor engaged in monitoring work at the remote monitoring base 8. The remote monitoring base 8 may be, for example, a higher-level management base such as the head office of a business operator that operates the plant body.

[0017] If an incident is detected at the site 2, the central control room 4, the inspection room 6, or the remote monitoring station 8, information about the incident is transmitted to each component of the plant facility 1 (the site 2, the central control room 4, the emergency control room 14, the response room 16, and the emergency response center 18) via various information transmission paths as shown in Figure 1, and can be used to consider how to respond to the incident. In addition, although multiple sites 2 and central control rooms 4 are shown in Figure 1, this is a conceptual representation of the fact that the sites 2 and central control rooms 4 may be the parties that detect an incident and may also be the parties that receive the detected incident (i.e., it does not necessarily mean that the plant facility 1 has multiple sites 2 and central control rooms 4).

[0018] The emergency control room 14 (ECR) is a facility for controlling and managing the plant main body in place of the central control room 4 in the event of an emergency such as the occurrence of a major incident. The emergency control room 14 is equipped with controller equipment (e.g., switches and support functions) required for stopping and cooling the plant equipment 1 in the event of an incident, and can continue to control and manage the plant main body even if the central control room 4 is unable to control it.

[0019] The countermeasure room 16 is a base where a plurality of personnel are summoned to consider an initial response when an incident occurs. The personnel summoned to the countermeasure room 16 are generally engaged in other work during normal times when no incident occurs. These personnel receive a summons request to the countermeasure room 16 in response to a summons notice delivered when an incident occurs. Conventionally, the countermeasure room 16 consolidates information about the incident transmitted from various places and considers an initial response while writing it out on a whiteboard or the like. In this embodiment, however, support is provided by the incident initial response support system 100 described below, making it possible to efficiently consider an initial response.

[0020] The emergency response room 18 (TSC: Technical Support Center) is a facility for considering additional responses to be implemented following the initial response considered in the response room 16 depending on the severity of the incident that occurred in the plant facility 1. For example, if the incident is relatively serious, the initial response considered in the response room 16 alone is insufficient, and further additional responses are required to settle the situation. In order to consider such additional responses, the emergency response room 18 determines the emergency action level (EAL), and considers additional responses according to the determination results, as well as additional responses required based on plant parameters and communication contents from each personnel (for example, arranging for an alternative battery or water source in the case where the power source or water source is lost on the plant building side).

[0021] FIG. 2 is an overall configuration diagram of a plant facility 1 equipped with an incident initial response support system 100 according to an embodiment, and FIG. 3 is a block diagram showing an internal configuration of the incident initial response support system 100 of FIG.

[0022] 2, in this plant facility 1, the central control room 4, emergency control room 14, response room 16, and emergency response center 18 are connected to one another via a communication network 20, enabling data transmission and reception between the facilities installed in each. An incident initial response support system 100 is further connected to this communication network 20. The incident initial response support system 100 obtains information related to the incident (hereinafter referred to as "incident information D1" as appropriate) transmitted from each location in the plant facility 1 via the communication network 20, and can appropriately support the response room 16 in considering an initial response to the incident.

[0023] As shown in FIG. 3, the initial incident response support system 100 includes an incident information acquisition unit 102, a convocation notice distribution unit 104, an initial incident information creation unit 106, a database 107, and an output unit .

[0024] The incident information acquisition unit 102 is configured to acquire incident information D1 received from each location of the plant facility 1 via the communication network 20. At each location of the plant facility 1, incidents are detected by various types of equipment and personnel installed as described above. That is, the detection of an incident itself may be performed automatically by various types of equipment or manually by personnel, but the detection result is acquired via the communication network 20 as incident information D1, which is electronic data.

[0025] The incident information D1 may include various forms, for example, alarms detected at various points in the plant facility 1 and contacts (emails, telephone calls, etc.) from various personnel such as operators. In addition, if the plant facility 1 includes a sign detection system for detecting signs of an incident based on past operating states, the incident information D1 may include information regarding signs of an incident.

[0026] The convocation notice distribution unit 104 is configured to automatically distribute a convocation notice to personnel who should be summoned to the response room 16 for initial response when an incident occurs. Personnel to whom the convocation notice is to be distributed are registered in advance, and the convocation notice is automatically distributed when incident information is acquired by the incident information acquisition unit 102. This makes it possible to quickly distribute the convocation notice to personnel who should be summoned when an incident occurs.

[0027] The convocation notice is distributed via the communication network 20, and is automatically distributed in various formats such as email or voice to a terminal or a portable terminal that can be operated by the personnel to be convened. The contents of the convocation notice are not limited, but may include, for example, the convocation date and time, the convocation location (i.e., the location of the response room 16), or simple information on the incident (such as an overview and importance of the incident).

[0028] The initial incident information creation unit 106 is configured to create initial incident information D2 based on the incident information D1. When an incident occurs, information about the incident is transmitted and received between the components of the plant facility 1 via various information transmission paths as described above with reference to Fig. 1. Therefore, in the past, it was not easy to select information useful for considering an initial response from this information and share the information with the many factors that are summoned to the response room 16. Conventionally, a typical process for considering an initial response in the response room 16 is, for example, as follows.

[0029] (i) First, based on the information on the incident obtained from each point in the plant equipment 1, time-series data such as alarms, operations, and external information from the past to the present is identified, and the status of the plant equipment 1 is grasped and organized. (ii) Next, by collecting and consolidating information related to the incident, the risk that the incident poses to the plant equipment 1 and the progress of the incident are predicted. (iii) Next, the information on the incident is analyzed, and based on the analysis results, analysis information including past similar cases is compiled. (iv) Next, based on the analysis results, the procedure for responding to the incident, reports, and information on required spare parts (requests for parts from manufacturers, response status, etc.) are considered. (v) Finally, the information obtained in (i) to (iv) is comprehensively considered, and an initial response is considered.

[0030] In this manner, in the conventional method, information on various incidents collected in the response room 16 is shared with many personnel, and initial responses are considered comprehensively. In the present embodiment, initial incident information D2 on at least some of the above (i) to (iv) is created based on incident information D1 collected from various locations in the plant facility 1, thereby making it possible to favorably support the consideration of initial responses. The specific contents of the incident initial information D2 will be described later.

[0031] The database 107 is configured to store various data that can be used when the initial incident information creation unit 106 creates the initial incident information D2. The data stored in the database 107 will be described in detail later, but for example, it includes reference information that is useful when personnel consider an initial response (for example, reference data on plants similar to the plant facility 1). The initial incident information creation unit 106 can access the database 107 to appropriately use the data stored in the database 107.

[0032] The output unit 108 is configured to output the initial incident information D2 to a display terminal 30 installed in the response room 16. At least one display terminal 30 is installed in the response room 16 that can be referenced by a plurality of personnel who have gathered in response to the convening notice. When the initial incident information D2 is output to the display terminal 30, a screen display corresponding to the initial incident information D2 is displayed. When this screen display is referenced by a plurality of personnel who have gathered in the response room 16, information regarding the incident is shared and support is provided for the consideration of the initial response.

[0033] In this embodiment, the output unit 108 outputs the incident initial information D2 to the multiple display terminals 30. The multiple display terminals 30 include a first display terminal 30a that can be simultaneously referred to by multiple personnel, and a second display terminal 30b that can be individually referred to by each of the multiple personnel. In the first display terminal 30a, the incident initial information D2 is displayed on, for example, a large screen display, so that multiple personnel can simultaneously refer to it and share information (for example, the first display terminal 30a is a large monitor or an electronic whiteboard). On the other hand, in the second display terminal 30b, the incident initial information D2 is displayed on a display (for example, a personal computer terminal display that can be operated by an individual) that is smaller than the first display terminal 30a, so that each individual can view the information that he or she wants to refer to according to individual requests. By displaying the incident initial information D2 on multiple display terminals 30 having different display scales in this way, it is possible to promote information sharing among personnel involved in the initial response and to suitably improve the quality of the initial response consideration.

[0034] The display terminal 30 to which the output unit 108 outputs the initial incident information D2 may be installed in multiple locations including the response room 16, so that the initial incident information D2 can be shared at multiple locations. In this case, the output destination of the output unit 108 may include the external environment of the plant facility 1 in addition to the inside of the plant facility 1. For example, the external environment may include not only related businesses involved in the operation of the plant facility 1, but also various organizations such as the national and local governments that are required to share information when an incident occurs. Furthermore, when an output format (template) is specified by the external environment, the output unit 108 may convert the initial incident information D2 into that format and output it.

[0035] Furthermore, the output unit 108 may output the initial incident information D2 created by the initial incident information creation unit 106 to the emergency response center 18. In the emergency response center 18, additional responses to be implemented after the initial response are considered, and the initial incident information D2 output from the output unit 108 can be used for the consideration. For example, if an additional response consideration support system for supporting the consideration of additional responses is installed in the emergency response center 18, the initial incident information D2 can be provided to the additional response consideration support system, thereby enabling support for the consideration of additional responses using the initial incident information D2 created in the response room 16.

[0036] Furthermore, when the emergency response center 18 is included as an output destination of the output unit 108, information on various tasks generated by the results of investigation and judgment in the response room 16 may be included in the response to the emergency response center 18 in addition to the incident initial information D2. In this case, by transferring (handing over) such information to the emergency response center 18, information sharing between the response room 16 and the emergency response center 18 can be promoted to enhance cooperation, thereby suitably improving the quality of response to incidents. For example, by arbitrarily registering tasks being performed in the response room 16 or tasks required later on the display terminal 30 of the response room 16, information on the registered tasks is displayed in a pop-up in the emergency response center 18. By accepting receipt of the information in response to the pop-up display, the emergency response center 18 can complete the handover of the information registered in the response room 16 to the information on the emergency response center 18 side. Although the sharing of information from the response room 16 to the emergency response center 18 has been described here, information may also be shared from the emergency response center 18 to the response room 16 based on a similar concept.

[0037] Next, a specific embodiment of the initial incident information D2 displayed on the display terminal 30 will be described. The initial incident information D2 is created so as to include at least one of information for multiple personnel in the response room 16 to grasp the situation of the incident, information for multiple personnel to make decisions regarding the initial response, and information for multiple personnel to plan the initial response. By including these pieces of information, the initial incident information D2 can favorably support the processes required of each personnel when considering the initial response, such as grasping the situation of the incident, making decisions, and planning a response.

[0038] The incident initial information D2 may include information regarding the occurrence history of the incident. For example, in the example shown in Fig. 4A, a timeline is displayed on the display terminal 30 as the incident initial information D2, in which the occurrence history of various events related to the incident that occurred in each of the systems A to C and the devices a to b constituting the plant main body is displayed in chronological order along a common time axis. In this timeline, alarm occurrences AR1 to AR5 and events E1 to E5 are displayed at positions corresponding to the occurrence times as the respective events that occurred for each system and device constituting the plant main body. Display items on such a timeline may include other items such as transitions of various parameters and operation history in addition to or instead of the alarm occurrences and events exemplified in Fig. 4A.

[0039] As described above, the incident information D1 acquired from each location in the plant facility 1 via the communication network 20 includes event information related to the incident in association with the time of occurrence. The initial incident information D2 is created by collecting the incident information D1 acquired from each location in the plant facility 1 via the communication network 20 as described above and chronologically organizing the event information included in this incident information D1. By displaying such initial incident information D2 as such a timeline on the display terminal 30, information regarding the process of the occurrence of the incident can be efficiently shared with each person in charge of the initial response. In FIG. 4A, alarms AR1 to AR5 and events E1 to E5 are displayed in a list format arranged in chronological order for each of systems A to C and devices a to b as various events related to the incident, but the display format is not limited to this.

[0040] The incident initial information D2 may include information on similar cases of the incident. In this case, the database 107 accumulates reference data on similar cases for each incident that may occur in the plant facility 1. The reference data may be past performance data of the plant facility 1, or may be performance data of other plant facilities having the same or similar specifications as the plant facility 1. The reference data may also be a simulation result.

[0041] The initial incident information creation unit 106 identifies an incident that has occurred in the plant facility 1 based on the incident information D1 acquired by the incident information acquisition unit 102, and searches the database 107 for reference data on similar cases to the identified incident. Then, the initial incident information creation unit 106 creates initial incident information D2 based on the reference data on similar cases obtained as the search results. By displaying the initial incident information D2 including such reference data on similar cases on the display terminal 30, it is possible to favorably support the consideration of an initial response.

[0042] The incident initial information D2 may also include an analysis format for the incident. The analysis format includes the analysis results using an analysis tool for searching for the cause of an incident that occurred in the plant facility 1. The analysis tool contains design data (FMEA, etc.) and past trouble information (including countermeasures, etc.) related to the part in question as a database, automatically extracts information that matches or is similar to the event in question from the acquired incident information, and presents the analysis results, etc. as necessary. In addition, the events handled by the analysis tool and the factors corresponding to the events may be arbitrarily input, selected, or replaced by the user, making it possible to create an analysis result corresponding to the event in question while referring to design data and past cases.

[0043] FIG. 4B shows a state transition diagram displayed on the display terminal 30 as an example of an analysis result by the analysis tool. The state transition diagram is a type of analysis tool that shows in schematic form what state the state of a plant in which an incident has occurred will transition to when a predetermined response is implemented. In the example of FIG. 4B, for a plant in which a specific incident has occurred, it is determined whether the power supply is in a normal state based on the judgment item S1. If the power supply is normal (judgment item S1: YES) and cooling can be performed (judgment item S2: YES), the plant is in state E. On the other hand, if cooling cannot be performed (judgment item S2: NO), the plant is in state A. Also, if the power supply is not normal (judgment item S1: NO), it is determined that the plant is in state B. And, if the safety function is enabled (judgment item S3: YES), the plant is in state C. On the other hand, if the safety function is not enabled (judgment item S3: NO), the plant is in state D. In addition, in FIG. 4B, a state transition diagram is illustrated as an example of an analysis tool. Another example is a fault tree (FT) for performing a cause analysis on a specific incident. may also be used.

[0044] Such an analysis tool may be prepared in advance in the database 107. In this case, a plurality of analysis tools may be prepared in the database 107, and an appropriate analysis tool may be selected depending on the occurrence circumstances of the incident. The initial incident information creating unit 106 displays the initial incident information D2 including the analysis results using such an analysis tool on the display terminal 30, thereby providing information on the analysis of the causes of the incident to each member in charge of the initial response, thereby favorably supporting the consideration of the initial response.

[0045] Furthermore, when multiple incident factors are determined using an analysis tool, incident initial information D2 may be created so that these incident factors are displayed in a ranked format based on information such as warnings, abnormal trends, analysis results, and failure rates contained in the incident-related information.

[0046] The initial incident information D2 may also include a first index regarding the degree of progression of the incident for each incident factor. When an incident factor is identified as an analysis result by the analysis tool as described above, how the incident will progress in the future is predicted for each incident factor, and the degree of progression is quantified as a first index. The degree of progression of such an incident can be predicted using, for example, artificial intelligence (AI), scraping technology, or a learning model.

[0047] The initial incident information D2 may also include a second index regarding the risk that the incident poses to the plant equipment 1. When incident factors are identified as analysis results by the analysis tool as described above, the risk that the incident will pose to the plant equipment 1 in the future is predicted for each incident factor, and the risk is quantified as a second index. Such risks to the plant equipment 1 can be evaluated using artificial intelligence (AI), scraping technology, and learning models.

[0048] The initial incident information D2 may also include information about spare parts (e.g., repair parts and equipment) required for the initial incident response. The information about spare parts is defined in advance in association with the incident cause obtained as the analysis result by the analysis tool as described above, and the initial incident information creating unit 106 can identify spare parts corresponding to the incident cause obtained as the analysis result by the analysis tool as described above based on the association, and include the information in the initial incident information D2. This allows multiple personnel in charge of the initial response to share information about spare parts required for the initial incident response, such as the presence or absence of stock, and the cost and time required for arranging.

[0049] The initial incident information D2 may also include image information for comprehensively or intuitively grasping the state of the plant equipment 1 on the display terminal 30. In the example of Fig. 4C, such image information shows a schematic configuration of a nuclear power plant, which is the plant equipment 1. By displaying such image information as the initial incident information D2 on the display terminal 30, it is possible for a plurality of personnel summoned to the response room 16 to comprehensively or intuitively grasp the state of the plant main body. In this embodiment, in addition to the bird's-eye view of the entire plant as shown in Fig. 4C, for example, by clicking on a relevant portion, the corresponding detailed content may be displayed. In this case, by switching between the bird's-eye view of the entire plant and the detailed display according to the user's desire, it becomes possible to efficiently collect information on the occurrence of an incident.

[0050] The initial incident information D2 may also include data on images and videos sequentially obtained at the scene 2, allowing the state of the scene 2 to be confirmed on the display terminal 30. In this case, multiple images and videos may be displayed simultaneously.

[0051] Various examples of the above-mentioned incident initial information D2 may be displayed with a predetermined priority on the display terminal 30. In this case, the display terminal 30 may be configured to preferentially display contents that display the status of the plant equipment 1 and the occurrence history of the incident from a macro perspective, and to be able to drill down from that information to contents that are displayed from a micro perspective.

[0052] As described above, according to each of the above embodiments, by outputting to the display terminal 30 initial incident information D2 created based on incident information D1 acquired from the incident occurrence area, information sharing among multiple personnel in charge of initial response can be made more efficient, and the consideration of initial response can be appropriately supported.
