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 can occur during plant operation, such as troubles occurring on-site or issues pointed out by regulators. Such incidents are recognized through reports from the site where the plant equipment is installed or from the base for controlling and managing the plant equipment (e.g., the central control room, the inspection room, or the head office / superior). When an incident is recognized, multiple personnel are summoned to a specific room to discuss the initial response to the incident. Currently, such initial response discussions are carried out by collecting information about the incident obtained through communication via telephone and email from all relevant parties and writing it down on a whiteboard or similar device.

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

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

[0005] Personnel responsible for the initial response to an incident are typically engaged in other duties when no incident is occurring. These personnel are summoned to a specific room designated for the purpose of considering the initial response in response to a convening notice sent out when an incident occurs, and they grasp the circumstances of the incident based on information collected in advance. Because the timing of personnel's arrival at the room varies depending on each personnel's situation, it is not easy to efficiently share information about the incident with personnel who arrive sequentially (for example, repeating the same explanation each time each personnel arrives at the room is inefficient). Furthermore, when considering the initial response to an incident, various information about the incident becomes jumbled, and it takes time to sort through this information to 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 initial responses to incidents. [Means for solving the problem]

[0011] Hereinafter, several 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 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 schematically illustrating an information transmission path when an incident occurs 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 field 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 main body is installed, and incidents (such as troubles that occur at site 2 during plant operation or notices from regulators) can be detected by workers monitoring the plant main body through inspections and patrols. Incidents detected at site 2 can be notified in various ways, including email, telephone (voice), and data (such as alarms and monitoring data), via a terminal that can be operated by the workers.

[0014] The central control room 4 (MCR: Main Control Room) is the main control facility for controlling and managing the plant main body installed at the site 2. In the central control room 4, the plant main body is controlled and managed, and the operating status of the plant main 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 affiliated companies, etc., and is an area for auditing and inspecting the plant equipment 1 (including both conducting 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 digital, and may also be presented on paper, on a screen, etc.). Comments from the auditor and observations from the auditee are converted into data and recorded using voice recognition. Flags can be set in the comment section or observation section of the recorded data (both automatically and manually), allowing incidents to be detected. Incidents detected in the audit room 6 can be reported in various ways, including email, telephone (voice), and digital data (alarms, monitoring data, etc.).

[0016] The remote monitoring base 8 is a base for remotely monitoring the operating status 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 status 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 the monitoring server installed at the remote monitoring base 8 or by 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 the business operator that operates the plant body.

[0017] When 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, or may be the parties that receive the detected incident (i.e., this 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 that controls and manages the plant main body in place of the central control room 4 in the event of an emergency such as when a serious incident occurs. The emergency control room 14 is equipped with controller equipment (such as switches and support functions) required to stop and cool the plant equipment 1 when an incident occurs, and can continue to control and manage the plant main body even if control by the central control room 4 becomes impossible.

[0019] The response room 16 is a base where multiple personnel are summoned to consider an initial response when an incident occurs. The personnel summoned to the response room 16 are generally engaged in other work during normal times when no incident has occurred. These personnel receive a summons request to the response room 16 in response to a summons notice sent when an incident has occurred. Conventionally, the response room 16 has collected information about the incident transmitted from various locations and written it down on a whiteboard or the like while considering an initial response. However, in this embodiment, support from the incident initial response support system 100, which will be described later, enables the initial response to be considered efficiently.

[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 has occurred in the plant facility 1. For example, if the incident is relatively serious, the initial response considered in the response room 16 alone will not be sufficient, and further additional responses will be required to resolve the situation. In order to consider such additional responses, the emergency response room 18 determines the emergency action level (EAL), considers additional responses based on the determination results, and considers additional responses that become necessary based on plant parameters and communication from each personnel (for example, arranging for an alternative battery or water source in the event that the power source or water source is lost in the plant building).

[0021] FIG. 2 is a diagram showing the overall configuration 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 the internal configuration of the incident initial response support system 100 shown in 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, thereby enabling data transmission and reception between the facilities installed in each. An incident initial response support system 100 is also connected to this communication network 20. The incident initial response support system 100 can obtain information about 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 effectively support the response room 16 in considering an initial response to the incident.

[0023] As shown in FIG. 3, the incident initial response support system 100 includes an incident information acquisition unit 102, a convocation notice distribution unit 104, an incident initial 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 via the communication network 20 from various locations in the plant facility 1. At each location in the plant facility 1, incidents are detected by the various types of equipment and personnel installed as described above. That is, the incident detection itself may be performed automatically by the various types of equipment or manually by personnel, but the detection results are acquired via the communication network 20 as incident information D1, which is electronic data.

[0025] The incident information D1 can include various forms, such as alarms detected at various locations in the plant facility 1 and communications (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 conditions, the incident information D1 may include information related to signs of an incident.

[0026] The convocation notice distribution unit 104 is configured to automatically distribute convocation notices 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 sent in various formats such as email or voice to a terminal or portable terminal that can be operated by the personnel to be convened. The content of the convocation notice is not limited, but may include, for example, the date and time of the convocation, the location of the convocation (i.e., the location of the response room 16), or simple information about the incident (such as an outline of the incident and its importance).

[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 has not been easy to select useful information from this information for considering an initial response and share this information with the numerous factors that lead to the emergency response room 16. In the past, a typical process for considering an initial response in the emergency response room 16 has been as follows, for example.

[0029] (i) First, based on the information about the incident obtained from each location in 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 plant equipment 1 is grasped and organized. (ii) Next, by collecting and consolidating information related to the incident, the risks posed by the incident to plant equipment 1 and the progression of the incident are predicted. (iii) Next, information about the incident is analyzed, and based on the analysis results, analytical information including past similar cases is compiled. (iv) Next, based on the analysis results, incident response procedures and reports, information on required spare parts (part requests to manufacturers, response status, etc.) are considered. (v) Finally, by comprehensively considering the information obtained in (i) to (iv), an initial response is considered.

[0030] In this way, in the conventional method, information about various incidents collected in the response room 16 is shared with many personnel, and initial responses are considered comprehensively. In this embodiment, initial incident information D2 regarding 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 contains 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 and use the data stored in the database 107 as needed.

[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 multiple 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 the multiple personnel who have gathered in the response room 16, information about the incident is shared and support is provided for considering the initial response.

[0033] In this embodiment, the output unit 108 outputs the initial incident information D2 to multiple display terminals 30. The multiple display terminals 30 include a first display terminal 30a that can be simultaneously accessed by multiple personnel and a second display terminal 30b that can be individually accessed by each of the multiple personnel. The first display terminal 30a displays the initial incident information D2 on, for example, a large screen display, allowing multiple personnel to simultaneously view and share information (for example, the first display terminal 30a is a large monitor or an electronic whiteboard). On the other hand, the second display terminal 30b displays the initial incident information D2 on a smaller display (for example, a personal computer terminal display that can be operated by an individual) than the first display terminal 30a, allowing each individual to view the information they wish to view according to their individual requests. Displaying the initial incident information D2 on multiple display terminals 30 with different display sizes in this way promotes information sharing among personnel involved in the initial response and effectively improves the quality of the initial response review.

[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, if 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. The emergency response center 18 considers additional responses to be implemented after the initial response, and can use the initial incident information D2 output from the output unit 108 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, providing the initial incident information D2 to the additional response consideration support system makes it possible to support the consideration of additional responses using the initial incident information D2 created in the response room 16.

[0036] Furthermore, if the emergency response center 18 is included as an output destination of the output unit 108, in addition to the incident initial information D2, information regarding various tasks arising from the results of investigations and decisions made in the response room 16 may be sent to the response room 18. In this case, by transferring (handing over) this information to the emergency response center 18, information sharing between the response room 16 and the emergency response center 18 can be promoted, enhancing cooperation, and thereby suitably improving the quality of response to incidents. For example, by arbitrarily registering tasks currently being performed in the response room 16 or tasks that need to be performed later on the display terminal 30 of the response room 16, information regarding the registered tasks is displayed in a pop-up at the emergency response center 18. By acknowledging 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 emergency response center 18. Although the above description concerns information sharing from the response room 16 to the emergency response center 18, 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 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 about the history of the occurrence of the incident. For example, in the example shown in FIG. 4A , the display terminal 30 displays, as the incident initial information D2, a timeline in which the history of various events related to the incident that occurred in each of the systems A to C and the devices a to b that constitute the plant main body is displayed in chronological order along a common time axis. On this timeline, alarm occurrences AR1 to AR5 and events E1 to E5 are displayed as events that occurred for each system and device that constitutes the plant main body, at positions corresponding to the occurrence time. Display items on such a timeline may include other items such as the transition 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 various locations 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 various locations in the plant facility 1 via the communication network 20 as described above and organizing the event information included in this incident information D1 in chronological order. By displaying this initial incident information D2 as such a timeline on the display terminal 30, information regarding the circumstances surrounding the occurrence of the incident can be efficiently shared with each personnel in charge of initial response. In Figure 4A, alarms AR1 to AR5 and events E1 to E5 are displayed in a list format arranged in chronological order for 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 initial incident information D2 may include information about similar cases of the incident. In this case, the database 107 stores reference data about similar cases for each incident that may occur in the plant facility 1. The reference data may be past performance data for the plant facility 1, or performance data for other plant facilities having the same or similar specifications as the plant facility 1. The reference data may also be simulation results.

[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 effectively support the consideration of an initial response.

[0042] The initial incident information D2 may also include an incident analysis format. The analysis format includes the analysis results obtained using an analysis tool for exploring the causes of an incident that occurred in the plant equipment 1. The analysis tool contains a database of design data (FMEA, etc.) and past trouble information (including countermeasures, etc.) related to the relevant part, automatically extracts information that matches or is similar to the relevant event from the acquired incident information, and presents analysis results, etc. as needed. 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 analysis results corresponding to the relevant event by 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 the analysis results obtained by the analysis tool. A state transition diagram is a type of analysis tool that schematically shows the state transition of a plant in which an incident has occurred 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 check item S1. If the power supply is normal (check item S1: YES), and if cooling can be performed (check item S2: YES), the plant will enter state E. On the other hand, if cooling cannot be performed (check item S2: NO), the plant will enter state A. If the power supply is abnormal (check item S1: NO), the plant will be determined to be in state B. Furthermore, if the safety function is enabled (check item S3: YES), the plant will enter state C. On the other hand, if the safety function is not enabled (check item S3: NO), the plant will enter state D. Although FIG. 4B illustrates a state transition diagram as an example of an analysis tool, other examples include a fault tree (FT) for performing a cause analysis of a specific incident. may also be used.

[0044] Such analysis tools 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 circumstances under which the incident has occurred. The initial incident information creating unit 106 displays the initial incident information D2 including the analysis results using such analysis tools on the display terminal 30, thereby providing information on the analysis of the causes of the incident to each person in charge of the initial response, thereby making it possible to favorably support the consideration of the initial response.

[0045] Furthermore, when multiple incident factors are determined using an analysis tool, the initial incident information D2 may be created so that these incident factors are displayed in a ranking 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 indicator related to the degree of progression of the incident for each incident factor. When incident factors are identified as analysis results using the analysis tool as described above, the future progression of the incident is predicted for each incident factor, and the degree of progression is quantified as a first indicator. Such an incident progression 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 related to 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, equipment, etc.) required for the initial incident response. The information about spare parts is predefined in association with the incident factors obtained as the analysis results by the analysis tool, as described above. The initial incident information creating unit 106 can identify spare parts corresponding to the incident factors obtained as the analysis results by the analysis tool, as described above, based on this association, and include that 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 whether they are in stock, the cost and time required to arrange them, etc.

[0049] The initial incident information D2 may also include image information for allowing the status of the plant facility 1 to be grasped from a bird's-eye view or intuitively 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 facility 1. By displaying such image information as the initial incident information D2 on the display terminal 30, it is possible for multiple personnel summoned to the emergency response room 16 to grasp the status of the plant proper from a bird's-eye view or intuitively. 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 part, 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 situation at 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-described 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 content that displays the status of the plant equipment 1 and the history of the incident from a macro perspective, and to be able to drill down from that information to content that is displayed from a micro perspective.

[0052] As described above, according to each of the above embodiments, by outputting to the display terminal 30 the initial incident information D2 created based on the incident information D1 acquired from the incident occurrence area, it is possible to efficiently share information among multiple personnel in charge of the initial response and to effectively support the consideration of the initial response.

[0053] In addition, within the scope of the present disclosure, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described embodiments may be combined as appropriate.
