Description

Technical Field

[0001] The present disclosure relates to a notification text generating apparatus, a notification text generating method, and a program.

Background Art

[0002] When an accident, failure, or other such event occurs at a nuclear power plant, the type and level of the event caused by the accident, failure, or other such event are determined based on EAL (Emergency Action Level). Events are classified into three levels based on facility information, radiation dose, and the like: "Alert (AL)", "Site Emergency (SE)", and "General Emergency (GE)", with the degree of urgency becoming more severe in the order of AL, SE, and GE (hereinafter, AL, SE, and GE are collectively referred to as emergencies). When it is determined that an emergency has occurred, the person in charge of the nuclear power plant must prepare a notification text reporting the occurrence of the emergency and submit the prepared notification text to relevant organizations. The work of preparing a notification text at the site of a plant, where confusion has arisen due to the occurrence of an emergency, is a burden.

[0003] As a related technology, Patent Document 1 discloses a system that acquires operating status data indicating the operating status of equipment in a nuclear power plant, determines an emergency that occurs due to the operating status of the equipment based on the acquired operating status data, and displays the determination result on a display device. However, Patent Document 1 does not disclose preparing a notification text reporting the occurrence of an emergency.

[Effects of the Invention]

[0010] The notification message creation device, notification message creation method, and program described herein can reduce the workload involved in creating and sending notification messages in the event of an emergency. [Brief explanation of the drawing]

[Figure 2] The first figure shows an example of a notification message according to the embodiment. [Figure 3] The second figure shows an example of a notification message according to the embodiment. [Figure 4] This figure shows an example of a notification message output instruction screen according to the embodiment. [Figure 5] This flowchart shows an example of the output process for a notification message according to the embodiment. [Figure 6] This figure shows an example of the hardware configuration of the monitoring device according to the embodiment. [Modes for carrying out the invention]

[0012] <Embodiment> The monitoring device described herein will be explained below with reference to Figures 1 to 6. (composition) Figure 1 is a block diagram showing an example of a monitoring device according to the embodiment. The monitoring device 10 acquires plant operation data from the nuclear power plant 1, determines the plant status based on the EAL which defines criteria for determining what kind of emergency has occurred at the nuclear power plant 1, and if an emergency has occurred, notifies the occurrence of the emergency, creates a notification document reporting the occurrence of the emergency, and sends the notification document to the relevant organization by means of transmission such as fax or email. The monitoring device 10 comprises a data acquisition unit 11, a determination unit 12, a setting unit 13, a creation unit 14, an output unit 15, a management unit 16, and a storage unit 17.

[0013] The data acquisition unit 11 acquires plant operation data from the nuclear power plant 1 and records the acquired plant operation data in the storage unit 17. The nuclear power plant 1 has a reactor system including a reactor and a turbine system including a steam turbine and a generator. The reactor is a light water reactor such as a pressurized water reactor (PWR) or a boiling water reactor (BWR). The reactor system and turbine system are equipped with various equipment and devices such as sensors, valves, pumps, and power supplies (external power supply, internal power supply, emergency power supply (emergency generator) and storage batteries) located at various points. The data acquisition unit 11 acquires plant operation data including operating status data of these devices, measured values ​​such as temperature, pressure, and radiation dose measured by various sensors, and user operation information and setting values ​​for various devices. In addition, when an earthquake occurs in the area where the nuclear power plant 1 is located, the data acquisition unit 11 acquires information such as the occurrence of the earthquake, the time of occurrence, the epicenter, and the magnitude of the shaking.

[0014] The determination unit 12 determines the type and level of an emergency occurring at the nuclear power plant 1 based on the plant operation data acquired by the data acquisition unit 11 and the related data. The related data is an emergency determination logic that defines the relationship between the operating status of equipment and the measured values ​​of sensors and the type and level of an emergency occurring at the nuclear power plant 1 indicated by that operating status and measured values. This related data conforms to the EAL judgment criteria, and the determination unit 12 determines the type and level of the emergency (AL, SE, GE). There are dozens of types of emergencies that can be determined, such as "abnormal reactor shutdown function," "reactor coolant leakage," "loss of reactor feedwater function" (in the case of BWRs), "loss of steam generator feedwater function" (in the case of PWRs), "increase in radiation levels near the site boundary," "loss of containment vessel integrity," and "loss of reactor control room function," and at least one level from AL, SE, and GE is associated with each of them. For example, AL and GE are associated with "abnormal reactor shutdown function," and AL, SE, and GE are associated with "reactor coolant leakage."

[0015] The relevant data includes, for example, a determination logic defined for each type and level of emergency, which determines that an AL-level "abnormality or potential abnormality in the reactor shutdown function" has occurred if several conditions are met, such as when a reactor shutdown signal is transmitted from nuclear plant 1 and this state continues for a certain period of time (determination condition 1), and that an SE-level "increase in radiation levels near the site boundary" has occurred if several conditions are met, such as when radiation measuring equipment installed at nuclear plant 1 measures a radiation level above a predetermined value (determination condition 2). If the operating data acquired by the data acquisition unit 11 includes a reactor shutdown signal or a radiation level measurement above a predetermined value, the determination unit 12 compares it with the relevant data and determines that an AL-level "abnormality or potential abnormality in the reactor shutdown function" has occurred if determination condition 1 is met, or that an SE-level "increase in radiation levels near the site boundary" has occurred if determination condition 2 is met. The determination unit 12 records the determination result and determination time in the storage unit 17. More specifically, for example, if the determination condition is 1, each time any of the conditions included in determination condition 1 is met, the determination unit 12 records the content of the met condition and the time when that condition was met in the storage unit 17. When all the conditions constituting determination condition 1 are met, the storage unit 17 records the time and the fact that determination condition 1 has been met. The types and levels of emergencies and their determination conditions differ depending on the plant, and the related data defines the determination logic for all emergencies that should be monitored at nuclear power plant 1. When an accident or malfunction occurs at nuclear power plant 1, the determination unit 12 determines what kind of emergency has occurred based on the plant's operating data and related data acquired by the data acquisition unit 11. However, since multiple emergencies can occur, the determination of emergencies is performed simultaneously. In addition, if the determination unit 12 determines that an emergency has occurred, it may determine the location where the emergency occurred (e.g., Unit X) based on the operating data.

[0016] The configuration unit 13 accepts settings for notification messages to be output when an emergency is determined to have occurred. For example, the configuration unit 13 accepts settings such as which notification message to output when an emergency occurs, a template that defines the format of the notification message, the items to be included in the notification message and their layout, what values ​​to set for each item in the notification message template, the means of sending the notification message (FAX or email), and the recipient of the notification message. For example, the configuration unit 13 accepts settings for a notification message template as exemplified in Figure 2 to be output when an AL level emergency occurs, and settings for a notification message template as exemplified in Figure 3 to be output when an SE level or GE level emergency occurs.

[0017] Figure 2 shows an example of a notification template that is output when an AL-level emergency occurs. Notification 200 includes a field 201 that displays which notification it is, a field 202 that displays the date (year, month, day) when notification 200 was output, a field 203 that displays the name of the contact person, a field 204 that displays the contact information, a field 205 that displays the name and location of nuclear plant 1, a field 206 that displays the location where the emergency occurred, a field 207 that displays the time the emergency occurred, a field 208 that displays the type of emergency that occurred, a field 209 that displays the cause of the emergency, a field 210 that displays the status of nuclear plant 1, a field 211 that displays reference information, and a field 212 that displays standard phrases, etc. The setting unit 13 accepts what information to set in fields 201 to 211. For example, field 201 may be set to display the number of notifications output since the accident at nuclear plant 1 occurred plus 1. Field 202 may be set to display the date on which the AL-level emergency that caused the notification to be output occurred. Columns 203-205 are set to display predetermined values, column 206 is set to display the location where the emergency occurred (e.g., Unit X of XX Power Plant), column 207 is set to display the time when the person in charge determined that an emergency had occurred, column 208 is set to display the type of emergency that the judgment unit 12 determined to have occurred, selected from a list of AL-level emergencies, column 209 is set to display the cause of the emergency that the judgment unit 12 determined to have occurred, and column 210 displays various conditions of the nuclear power plant 1 at the time of the emergency (reactor operating status, ECCS (Emergency Core Cooling)). The system accepts settings to select and display the operating status of the system, the indicated value of the exhaust stack monitoring, and the indicated value of the monitoring post. For field 211, the system accepts settings to display the details of the event that caused the emergency, the time the event occurred, the time the determination unit 12 determined that an emergency had occurred, the last condition that led the determination unit 12 to determine that an emergency had occurred, a standard phrase, and in the event of an earthquake, the epicenter, time of occurrence, magnitude of shaking, etc. For field 212, the system accepts settings to display a standard phrase.In addition to the occurrence time of the emergency determined by the person in charge (column 207), the time when the system (determination unit 12) determined the occurrence of the emergency (column 211) is described in the notification message, which can be used as a reference when reviewing the response to the occurrence of the emergency.

[0018] FIG. 3 shows an example of a notification message template output when an SE-level or GE-level emergency occurs. The notification message 300 includes a column 301 for displaying which round of notification message is output, a column 302 for displaying the date (year, month, day) when the notification message 300 is output, a column 303 for displaying the name of the contact person, a column 304 for displaying the contact information, a column 305 for displaying the name and location of the nuclear power plant 1, a column 306 for displaying the location where the emergency occurred, a column 307 for displaying the occurrence time of the emergency, a column 308 for displaying the type and level of the occurred emergency, a column 309 for displaying the cause of the emergency, a column 310 for displaying the status of the plant, a column 311 for displaying reference information, and a column 312 for displaying fixed phrases and the like. The settings of columns 301 to 312 are the same as the settings of columns 201 to 212 described in FIG. 2, except for the difference between AL and SE or GE (column 301 is the same as column 201, column 302 is the same as column 202, and the same applies to columns 303 to 312).

[0019] Note that the setting unit 13 accepts settings for fixed phrases to be displayed in columns 211 and 212 of FIG. 2 and columns 311 and 312 of FIG. 3, and records the set fixed phrases in the storage unit 17. The fixed phrases can be changed, and the setting unit 13 records the history of changes to the set fixed phrases in the storage unit 17.

[0020] For example, regarding columns 211 and 311, a setting to describe the following fixed phrases is accepted. "(In the case where an earthquake with a seismic intensity of 6 lower or higher* occurs in the municipality where the nuclear power plant is located) * If the event is considered to be related to the occurrence of the alert situation, the observed seismic acceleration measured by the observation seismograph shall be described regardless of the seismic intensity."

[0021] In addition, regarding columns 212 and 312, a setting to describe the following fixed phrases is accepted. The following are the safety regulation settings that will result in an automatic reactor shutdown using a reactor protection seismometer, which is different from an observational seismometer. Unit ○ Horizontal direction (ELXX.Xm): XXX gal or less, Horizontal direction (ELXX.Xm): XXX gal or less, Vertical direction (ELXX.Xm): XX gal or less"

[0022] The setting unit 13 and the creation unit 14 and output unit 15 described below may include a generally available form tool (a system that has the function of setting data in a form template to generate electronic form data and outputting it via email, fax, etc.). The operator can use the means provided by the form tool to register and edit the notification form template and set what values ​​to display in fields 201 to 212 and fields 301 to 312. Then, for example, by performing a predetermined operation, the operator can create electronic form data 2 of the notification form with the desired information set in fields 201 to 212 and fields 301 to 312.

[0023] The creation unit 14 creates a notification based on the determination of the judgment unit 12. For example, if the judgment unit 12 determines that an AL level "abnormality or potential abnormality of the reactor shutdown function" has occurred, the creation unit 14 decides to create a notification using the template shown in Figure 2, and displays the notification output instruction screen 400 shown in Figure 4 on the display device. The notification output instruction screen 400 includes an input field 401 for the time of occurrence, an input field 402 for the suspected cause, an input field 403 for the reactor operating state (before occurrence), an input field 404 for the reactor operating state (after occurrence), an input field 405 for the operating state of the ECCS, an input field 406 for the exhaust stack monitoring instruction value, an input field 407 for the monitoring post instruction value, other input fields 408, and an output instruction button 409. The operator enters the time in the input field 401 that the person in charge of the nuclear plant 1 determined that the emergency determined by the judgment unit 12 had indeed occurred. The operator selects a possible cause of the emergency from the following options: malfunction, user error, leak, fire, explosion, earthquake, under investigation, or other, and enters the selected value in input field 402. If "other" is selected, the operator enters the possible cause in input field 402.

[0024] The operator selects the reactor's operating status before the emergency from "Operating," "Startup Operation," "Shutdown Operation," and "Shutdown," and enters the selected value in input field 403. The operator selects the reactor's operating status after the emergency from "Status Continuing," "Shutdown Operation," "Shutdown," and "Shutdown Failed," and enters the selected value in input field 404. The operator selects the ECCS's operating status from "Not Operating," "Operating (Automatic)," "Operating (Manual)," and "Operation Failed," and enters the selected value in input field 405. The operator selects the exhaust stack monitoring reading from "Under Confirmation," "No Change," and "Changed," and enters the selected value in input field 406. If "Changed" is selected, the operator enters the readings before and after the change in input field 406. The operator selects the monitoring post reading from "Under Confirmation," "No Change," and "Changed," and enters the selected value in input field 407. If "Changed" is selected, the operator enters the readings before and after the change in input field 407. The operator enters the information that should be entered in column 211 of Figure 2 into input field 408. After entering the information into input fields 401 to 408, the operator presses the output instruction button 409.

[0025] The creation unit 14 then checks for any missing items and performs a spell check to verify that the entered information is correct, and displays a warning if there are any deficiencies. For example, if the date and time entered in input field 401 deviates by more than a predetermined time from the date and time determined by the judgment unit 12 to be an emergency, it determines it to be an error and displays a warning requesting correction of the date and time. Also, if there are any missing entries or typographical errors, it determines it to be an error and displays a warning requesting input in the missing items or correction of the typographical errors. If there are no errors, the creation unit 14 sets the information based on the settings received by the setting unit 13 and the information entered on the notification output instruction screen 400 in fields 201 to 212 of the notification template in Figure 2 to create electronic data 2 of a notification message reporting the occurrence of an AL level emergency.

[0026] For example, the creation unit 14 sets a value indicating the number of the notification in field 201, sets the current date in field 202, sets the information received by the setting unit 13 in fields 203 to 205, sets the location where the emergency determined by the judgment unit 12 occurred in field 206, sets the time (year, month, day, hour, minute) entered in input field 401 of the notification output instruction screen 400 in field 207, selects the type of emergency determined by the judgment unit 12 in field 208 (if multiple emergencies occur, multiple events will be checked), and fields 209 and 210 are for notification output. The settings are configured to enclose items entered in input fields 402 to 407 of the instruction screen 400 in circles or squares for display. Field 211 is set to automatically contain the time and last event that occurred when the judgment unit 12 determined that an emergency had occurred, the time and event that caused the emergency that the judgment unit 12 determined occurred, the items entered in input field 408 of the notification message output instruction screen 400, the standard text that the setting unit 13 accepted, and, in the case of an earthquake, the epicenter, time of occurrence, and magnitude of shaking acquired by the data acquisition unit 11. Field 212 is set to contain the standard text that the setting unit 13 accepted, and electronic data 2 is created. Regarding fields 209 and 210, the information is displayed based on the information entered in input fields 402 to 407 of the notification message output instruction screen 400. However, the determination unit 12 may determine the cause of the emergency based on the operating data, determine the operating status of the reactor and the status of the nuclear power plant 1 from the operating data, extract the operating status of the ECCS, the readings of the exhaust stack monitor and the readings of the monitoring posts from the operating data, and the creation unit 14 may receive the cause and operating status determined by the determination unit 12, the operating status of the ECCS extracted by the determination unit 12, etc., and set fields 209 and 210 based on the received information. In addition, the information to be displayed in fields 209 and 210 may be entered and edited by the operator on an editable preview screen, which will be described later, rather than being entered from the notification message output instruction screen 400. Furthermore, field 207 may be set to the time when the determination unit 12 determined that an emergency had occurred.

[0027] Furthermore, the creation unit 14 outputs an interface (editable preview screen) to the display device that displays the created electronic data 2, allows the operator to check the contents of the electronic data 2, and changes the information of each item as needed. Through this screen, the operator can edit the automatically entered items and the information entered from the notification message output instruction screen 400. When the operator confirms the output on this screen, the creation unit 14 finalizes the contents of the electronic data 2. The finalized notification message electronic data 2 is then versioned by the management unit 16 and recorded in the storage unit 17.

[0028] Similarly, if the determination unit 12 determines that an SE or GE level emergency has occurred, the creation unit 14 displays the notification message output instruction screen 400, as illustrated in Figure 4, on the display device and accepts input into input fields 401 to 408 and the operation of pressing the output instruction button 409. Then, the creation unit 14 sets the information based on the settings received by the setting unit 13 and the information entered on the notification message output instruction screen 400 in fields 301 to 312 of the notification message template in Figure 3, creates electronic data 2 of a notification message reporting that an SE or GE level emergency has occurred, and outputs an editable preview screen to the display device. When the operator confirms the output on the editable preview screen, the creation unit 14 finalizes the contents of the electronic data 2. The finalized electronic data 2 of the notification message is versioned by the management unit 16 and recorded in the storage unit 17.

[0029] In Figure 4, the operator selects from a list of options regarding the expected cause and the status of the nuclear power plant 1 (input fields 402-407). However, the determination unit 12 may have a function to automatically set some or all of these items based on the operating data. For example, if the operating data includes a signal indicating equipment failure, the determination unit 12 may estimate that the expected cause is "failure" and initially display "failure" in input field 402. Furthermore, regarding the operating status of the reactor, the determination unit 12 may determine from the operating data whether it is "operating," "startup in progress," "shutdown in progress," or "shut down," and initially display the determined operating status in input field 403. The same applies to the other input fields 404-407.

[0030] When the determination unit 12 determines that an emergency has occurred, the output unit 15 outputs the type and level of the emergency determined to have occurred to the display device, and also outputs the electronic data 2 of the notification message created by the creation unit 14. For example, if the setting unit 13 receives a setting to send the notification message to the recipient by fax, the output unit 15 outputs the electronic data 2 of the notification message along with the recipient's fax number to a fax transmitter (not shown) and instructs it to send to the recipient. The fax transmitter sends the electronic data 2 of the notification message to the recipient via a telephone line. For example, if the setting unit 13 receives a setting to send the notification message to the recipient by email, the output unit 15 generates an email with the electronic data 2 of the notification message attached, sets the recipient's email address, outputs it to a mail server (not shown), and instructs it to send to the recipient. The mail server sends the electronic data 2 of the notification message to the recipient via a network such as a LAN. The output unit 15 also outputs the electronic data 2 of the notification message created by the creation unit 14 to a printer and prints it on paper.

[0031] The management unit 16 manages the versions of the electronic data 2 of the notification document created by the creation unit 14. For example, a notification document printed on paper may be corrected by hand. The management unit 16 acquires the electronic data of the corrected notification document, which has been scanned, and stores it in the storage unit 17. It manages the electronic data 2 of the notification document before correction and the electronic data of the corrected notification document in association. The management unit 16 also records the electronic data 2 of previously created notification documents in the storage unit 17, associating them with their respective creation times, and accepts changes and deletions to them. If changes or deletions occur, it manages the history of changes and deletions. Furthermore, it assigns versions to the electronic data 2 of the notification document before and after correction and performs version control. In addition, it provides operators with an interface that allows them to copy the electronic data 2 of previously created notification documents to create new electronic data 2 of notification documents and freely edit the content of that electronic data 2. The system also has a function to send new reports via fax or other means by recording the edited electronic data 2 of the report in the storage unit 17 for version management and outputting it to the output unit 15. Furthermore, the management unit 16 records the registered templates of the report received by the setting unit 13 in the storage unit 17 along with the registration time, accepts changes and deletions to these templates, manages the history of changes and deletions, and manages the version of the templates when changes or deletions occur. In addition, when changing a template, it is possible to create a new template by reusing a previous version of the template.

[0032] The memory unit 17 stores moment-by-moment plant operation data acquired by the data acquisition unit 11, relevant data for determining an emergency, the time when the determination unit 12 made various determinations, for example, the time when each condition constituting determination condition 1 was met regarding "AL level 'abnormality or risk of abnormality in reactor shutdown function'", the time when all conditions were met, various settings received by the setting unit 13, information entered on the notification message output instruction screen 400, electronic data 2 of the notification message created by the creation unit 14, and electronic data 2 of each version of the notification message managed by the management unit 16.

[0033] (operation) Next, we will explain the output process of the notification message using Figure 5. Figure 5 is a flowchart showing an example of the output process for a notification message according to this embodiment. First, the setting unit 13 accepts the settings for the notification message (step S1). The setting unit 13 accepts settings such as which notification message to output when a particular emergency occurs, what values ​​to set for each item in the notification message template, the means of sending the notification message, and the recipient. Next, the data acquisition unit 11 acquires the plant's operating data (step S2). The determination unit 12 determines whether an emergency of any level has occurred at the nuclear power plant 1 based on the plant's operating data acquired in step S1 and the related data (step S3). The determination unit 12 makes this determination based on the emergency-specific and level-specific determination logic included in the related data. If the plant's operating data satisfies the conditions for any of the determination logics, the determination unit 12 determines that an emergency of the level corresponding to the conditions has occurred; otherwise, it determines that no emergency has occurred. If it is determined that no emergency has occurred (step S3; No), the process proceeds to step S6. If the creation unit 14 determines that an emergency of any level has occurred (Step S3; Yes), it outputs the notification message output instruction screen 400, as illustrated in Figure 4, to the display device and accepts input into input fields 401 to 408 and pressing the output instruction button 409. The creation unit 14 then creates the electronic data 2 of the notification message (Step S4). For example, if the determination unit 12 determines that an AL level emergency has occurred, the creation unit 14 creates the template electronic data 2, as illustrated in Figure 2, and outputs an editable preview screen to the display device. The operator modifies the content of the notification message as needed and confirms the output. The management unit 16 assigns a version number to the created electronic data 2 of the notification message and records it in the storage unit 17. The creation unit 14 outputs the created electronic data 2 of the notification message to the output unit 15. Next, the output unit 15 outputs the electronic data 2 of the notification message based on the transmission means and destination settings received by the setting unit 13 (Step S5). For example, the output unit 15 sends the electronic data 2 of the notification message via fax.

[0034] Next, the monitoring device 10 determines whether or not to terminate monitoring of the nuclear power plant 1 (step S6). For example, if a user performs an operation to instruct the termination of monitoring, the monitoring device 10 determines to terminate monitoring; otherwise, it determines not to terminate monitoring. If it determines to terminate monitoring (step S6; Yes), the flow in Figure 5 is terminated. If it determines not to terminate monitoring (step S6; No), the process from step S2 is repeated. As a result, each time the determination unit 12 determines that an emergency has occurred, electronic data 2 of the notification message is created and sent to the relevant organization.

[0035] (effect) As described above, this embodiment allows for the semi-automated creation and transmission of emergency notices in the event of an emergency. More specifically, information is automatically entered into fields that can be automatically filled into a predetermined format, and the operator selects appropriate information from the options for fields that can be selected, making it easy to create an emergency notice. Furthermore, the created emergency notice can be modified, and by pre-setting the means of communication and recipients, the emergency notice can be automatically sent to the relevant organizations. This reduces the burden of creating and transmitting emergency notices.

[0036] Figure 6 shows an example of the hardware configuration of the monitoring device. The computer 900 includes a CPU 901, main memory 902, auxiliary memory 903, input / output interface 904, and communication interface 905. The monitoring device 10 described above is implemented in the computer 900. The functions described above are stored in the auxiliary memory 903 in the form of programs. The CPU 901 reads the program from the auxiliary memory 903, expands it into the main memory 902, and executes the above processing according to the program. The CPU 901 also allocates memory space in the main memory 902 according to the program. The CPU 901 also allocates memory space in the auxiliary memory 903 to store data being processed according to the program.

[0037] Furthermore, a program to implement all or part of the functions of the monitoring device 10 may be recorded on a computer-readable recording medium, and the program recorded on this recording medium may be loaded into a computer system and executed to perform processing by each functional unit. Here, "computer system" includes hardware such as the OS and peripheral devices.
