Description

An embodiment of the present invention relates to a periodic inspection process creation support device, a periodic inspection process creation support method, and a periodic inspection information linkage system of a power generation plant such as nuclear power, thermal power, and other plants.

In the background technology shown below, a nuclear power plant will be described as an example of a power plant.
At nuclear power plants, periodic inspections (regular inspections) are carried out in accordance with prescribed safety standards, such as periodically shutting down the operation of each plant to ensure the criticality prevention function of the nuclear reactor and the function of removing the decay heat of fuel. Will be done. The plant condition at the time of regular inspection changes greatly depending on the process such as refueling. For example, the reactor water level is raised to move fuel between the reactor and the fuel pool, and the channel gates are opened during transfer. Periodic inspection processes such as equipment inspection and replacement are planned while ensuring the safety of the plant while following these basic procedures.

The regular inspection process of a nuclear power plant is not uniform and varies from plant to plant. For this reason, the regular inspection process is planned in advance by a veteran engineer each time, and the regular inspection process chart is created. In creating such a regular inspection process chart, the number of artificial numbers required for work, the number of days, parts to be arranged, work process, staffing, securing of work place, work constraints, preparation of documents necessary for work, etc. Taking this into consideration, skilled engineers with a high degree of skill performed scheduling (schedule creation and management) including staffing.

Specifically, after the schedule for each inspection work is created manually by a skilled technician, the scheduling work is performed by constructing the schedule for the entire inspection work while avoiding interference between the works. Was there.

In addition, during the actual regular inspection work period, the work report was made from the field worker to the field work supervisor, and based on this, the skilled technician grasped the work progress status and made necessary schedule corrections.

Further, in order to support the planning of the regular inspection process as described above, an apparatus for supporting the creation of various regular inspection processes has been conventionally proposed.

However, in the regular inspection process of a nuclear power plant, it is necessary to consider many constraints such as isolation (system isolation), avoidance of work area interference, and compliance with maintenance regulations while multiple operations are performed in parallel. There is. The regular inspection process plan that satisfies these constraint conditions is created by relying on the knowledge and experience of skilled engineers, but the number of skilled engineers will inevitably decrease in the future, and in the future regular inspection process, there is a risk of deficiencies. There is concern about the occurrence.

In addition, for example, if there is a delay in the work after starting the regular inspection, and it is necessary to inform the related workers of the cause and situation and make adjustments for the subsequent work, etc., the experience of a skilled technician has been used in the past. It is proceeding by relying on knowledge. On the other hand, after the Great East Japan Earthquake, the retirement of engineers began due to the long off-season, and with the introduction of a new inspection system, in addition to the proximity risk management around important equipment responsible for the core cooling function, new fires and floods, etc. There is also a tendency for management and inspection to be imposed, and more and more advanced knowledge and experience are required for regular inspections for restarting operations.

In view of these situations, an object of the present invention is to inform workers of related work, etc. of the cause, location, and system operation when a delay or advance occurs in the regular inspection process of a power generation plant, nuclear power, thermal power, or other plants.

Hereinafter, the periodic inspection process creation support device and the periodic inspection process creation support method of the embodiment will be described with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of a periodic inspection process creation support device 100 according to an embodiment. As shown in FIG. 1, the periodic inspection process creation support device 100 includes a database 101, a process creation support unit 110, an input unit 121, a display unit 122, and a work order control unit 130.

The database 101 stores the execution work information 102, the inspection equipment data 103, the safety regulation data 104, and the past regular inspection process actual data 105 during the regular inspection period.

The execution work information 102 during the regular inspection period stores information about the work to be performed during the regular inspection period, which is input from the input unit 121 by the process chart creator. This information includes basic information related to the critical process (nuclear power plant name, number of regular inspection days, number of fuel exchanges, number of neutron detector exchanges, number of control rod drive mechanism inspections, etc.), and during the regular inspection period other than the critical process. Contains information about the inspection equipment to be carried out in.

The inspection equipment data 103 relates to related risk information such as inspection results, isolation, work area, important equipment, fire protection zone, overflow boundary, dose rate, area classification of controlled area, etc. for each equipment of the nuclear power plant. Contains data. The data on the inspection results include data on the required number of days based on the past inspection results.

The above-mentioned safety regulation data 104 stores data on all safety regulations in a nuclear power plant, that is, all requirements for process creation, and the periodic inspection process chart is such that all the requirements are satisfied. Is created in.

The past regular inspection process actual data 105 stores information related to the critical process and information related to the inspection of the equipment performed other than the critical process with respect to the processes performed in the past regular inspection.

The work order control unit 130 makes work order-related settings based on the information stored in the database 101. The work order control unit 130 has various functions for setting the main work order. For example, the data accumulated in the above-mentioned database 101 is used as a target device for work, tasks related to work, order of work, instruction manual, cost required for work, form of work, date and time when work is executed, and work is executed. Sort and control by which classification, the place to do, the risk information, the time required for the work, the planning information and the actual information on the above, the information about the organization or department to perform the work, the personnel assigned to the work.

As shown in FIG. 2, the work order control unit 130 has a work order setting unit 131, a work order registration unit 132, a plan information registration unit 133, and an actual information registration unit 134 as basic configurations. The work order setting unit 131 accepts a setting for dividing at least one main work order related to the periodic inspection into a plurality of sub work orders. The work order registration unit 132 registers a sub work order ID that can individually identify a sub work order in a database (process management database) 101. The plan information registration unit 133 registers the plan information indicating the work plan in the database (process management database) 101 in association with the related subwork order ID. The performance information registration unit 134 registers the performance information indicating the work performance in the database (process management database) 101 in association with the subwork order ID. As a configuration that fulfills other functions of the work order control unit 130, for example, a message processing unit 135, a message storage unit 136, an area registration unit 137, a delay display unit 138, a request reception unit 139, a request display unit 140, and the like are provided.

The main work order of this embodiment is created for each device to be inspected. For example, one main work order is created for the inspection work of one device, and the device to be inspected is on the critical path, important equipment, fire protection section, flood boundary, dose rate, etc. Priorities may be assigned according to the high risk associated with the area classification of the controlled area, etc.

The work order control unit 130 sets the main work order to be divided into a plurality of sub work orders. For example, as shown in FIG. 3, the main work order is divided into a plurality of sub work orders based on at least one of the departments involved in the periodic inspection, the form of the periodic inspection, and the equipment subject to the periodic inspection.

The term "division" in the present embodiment means that individual items included in one main work order are divided. In this way, it is possible to manage each form of periodic inspection based on the sub-workorder without changing the contents of the main work order. In addition, information sharing and cooperation between departments can be strengthened. In addition, it is possible to manage each device. Each sub-work order is given a sub-work order ID that can individually identify the sub-work order. FIG. 4 shows an example of a work order management table that summarizes them.

As shown in FIG. 4, in the work order management table, the main work order ID, the related department, the work mode, the target device, the related sub work order ID, and the change history are registered in association with the sub work order ID. .. The plan information includes a subwork order ID, a main work order ID, a related department, a work mode, a target device, and a related subwork order ID.

In the related department item, the department related to the periodic inspection and performing the work of the corresponding subwork order is registered. The image shown in FIG. 4 can be viewed not only from the group that actually performs the inspection work but also from other groups (parallel or subsequent work group, etc.) that need to share information. Further, since each is linked with the work order for each subject and the sub-work order ID information classified into the work form, etc. via the work order control unit 130, as shown in FIG. 4, a plurality of departments included in the A group are linked. Of these, the prescribed department is registered. In the item of this related department, a department ID that can individually identify each department may be registered.

In the item of work form, the work form of the corresponding subwork order, which is a form of periodic inspection, is registered.

In the item of the target device, the name or type of the device that is the target of the periodic inspection and is the target of the work of the corresponding subwork order is registered. A device ID that can individually identify each device may be registered in the item of the target device.

In the item of the related subwork order ID, the subwork order IDs of other subworkorders related to the corresponding subworkorder are registered. This subworkorder may be split from other main workorders. It should be noted that although the same ID number can be used between subwork orders registered from different main work orders, identification is possible when the main work orders are included.

In this embodiment, a plurality of main work orders include a first main work order and a second main work order different from the first main work order. When the sub-workorder divided from the first main work order is related to the second main work order, the sub-work order ID of the first main work order is associated with the second main work order in the work order management table. to register. In this way, the work of the first main work order and the second main work order can be coordinated with each other. For example, if a predetermined sub-workorder of the first main work order is delayed or advanced, other related sub-work orders can be identified based on this sub-work order ID. Therefore, even if the main work orders are different, the sub work orders can be linked with each other.

In the present embodiment, a first-class tree structure is configured by a work step branching from the work subject, which is the main work order, and a work step branching from the work step. In addition, a second type tree structure is composed of subwork orders that branch off from the main work order. In the present embodiment, the first type tree structure and the second type tree structure are individually constructed. That is, a first-class tree structure for dividing the work and a second-class tree structure for linking one work with other work are provided. The first-class tree structure and the second-class tree structure are different from each other.

The process creation support unit 110 includes a regular inspection process creation procedure creation function 111, a process chart creation function 112, a communication function 113, and a process monitoring unit 114.

In creating the regular inspection process chart, the process chart creator first inputs the execution work information during the regular inspection period from the input unit 121 (step 201 in FIG. 5 (flow chart)). The input work information during the regular inspection period is stored in the database together with the information associated with the main work order for each subject and the sub work order ID classified into the work form, etc. via the work order control unit 130. It is stored in 101.

The regular inspection process creation procedure creation function 111 creates a regular inspection process creation procedure based on the execution work information 102 during the regular inspection period stored in the database 101. First, out of the implementation work information 102 during the regular inspection period, basic information related to the critical process (nuclear power plant name, regular inspection days, number of refueling, number of neutron detector replacements, number of control rod drive mechanism inspections, etc.) Based on the above, a regular inspection process chart (main process chart) for the main process is automatically generated from the past actual data and displayed on the display unit 122 (step 202 in FIG. 5). An example of the regular inspection process chart is shown in FIG.

In a more specific example, when the process chart creator starts creating the process chart, the periodic inspection process creation support device 100 displays "reactor critical process creation" on the display screen. When the creator of the process chart selects and executes the displayed "Reactor critical process creation", it is linked to the main work order for each subject and the sub-work order ID classified into the work form, etc. via the work order control unit 130. Generator disconnection, reactor opening, refueling, neutrons based on the generator disassembly date and generator parallel date in the implementation work information during the regular inspection period stored in the database 101 together with the information Create a template of the critical process consisting of detector replacement, reactor restoration, reactor leak inspection, reactor pre-startup test, reactor start-up, and generator installation and display it on the screen.

Next, the number of fuel exchanges, the number of neutron detectors exchanged in the construction information during the regular inspection period stored in the database 101, and the actual fuel exchange time and neutron detector exchanges in the past fixed inspection process actual data. Based on the time, the time required for fuel and neutron detector replacement in the regular inspection is calculated and reflected in the critical process template fuel replacement and neutron detector replacement process.

Next, the reactor opening and the reactor in the past regular inspection process actual data stored in the database 101 together with the information associated with the main work order for each subject and the sub-work order ID classified into the work form, etc. Reactor restoration, reactor leak inspection, reactor pre-startup test, based on the actual time of reactor startup, critical process model reactor opening, reactor restoration, reactor leak inspection, reactor pre-startup test, reactor startup Reflect in the process.

Next, the above-mentioned critical process template reflecting the past fixed inspection process actual data is displayed on the screen as the critical process of the fixed inspection work.

Next, the regular inspection process creation procedure creation function 111 is based on information about inspection equipment, inspection equipment data, and safety regulation data to be carried out during the regular inspection period other than the input critical process. A procedure for assigning inspection times in order (priority) is created and displayed (step 203 in FIG. 5).

For example, when A, B, C, D, and E are input as inspection devices, the order in which the inspection times of these inspection devices are assigned, for example, the order of A → D → C → E → B, etc. is displayed. Therefore, in the creation of the regular inspection process, the process chart creator assigns the inspection time of the inspection equipment in the displayed order. For example, the above priority is given to the construction of reactor equipment that directly affects the critical process, then the construction of equipment related to fuel cooling, then the construction of equipment related to radioactivity confinement, and then the construction period. It is decided that long construction work, then important equipment construction work, and so on. Then, a list of prioritized construction subjects is displayed on the screen.

When allocating the inspection time of the above-mentioned inspection equipment to the main process chart including the above-mentioned critical process, the process chart creation function 112 is used.

When the first inspection device displayed in the above procedure, for example, A is selected (step 204 in FIG. 5), the process chart creation function 112 selects the inspection device data related to A from the inspection device data 103 of the database 101. Extract. The inspection equipment data related to A includes the inspection results for A (including the required inspection period), the data related to isolation (system isolation) required when inspecting A, and the inspection of A. The data related to the work area required for performing the above, and the sub-work order ID information classified into the main work order and the work form for each subject via the work order control unit 130 are included. These data can be displayed on the display unit 122 by an operation by the input unit 121 when the process chart creator desires.

Further, the process chart creation function 112 extracts the safety regulation data related to the selected inspection device A from the safety regulation data 104. Then, all the requirements (constraints) for creating the process related to the inspection device A can be displayed on the display unit 122 by the operation by the input unit 121 when the process table creator desires.

In this way, the process chart creator is required to have information on the inspection device A displayed on the display unit 122, that is, inspection results (including the required inspection period) for A, information on isolation, and so on. You can see information about the work area and all the requirements for process creation. At this time, the period during which the inspection time of the inspection device A can be assigned (candidates that can be assigned) is displayed in the main process chart displayed on the display unit 122 (step 205 in FIG. 5). In addition, all the requirements (constraints) for creating the process related to the inspection device A are displayed as a check table, and the grounds for the requirements can also be displayed as necessary.

Based on the information displayed on the display unit 122, the process chart creator allocates the inspection time for the inspection device A in the main process table in which the critical process is displayed (step 206 in FIG. 5).

In the same manner, the inspection time of the inspection equipment is sequentially assigned to the main process chart in the order of inspection equipment D → C → E → B, and the entire regular inspection schedule is created (step 207 in FIG. 5). In this case, the regular inspection process chart being created is stored in the database 101 together with the main work order for each subject and the sub-work order ID information classified into the work form, etc. via the work order control unit 130, and is stored in the database 101 as needed. Can be read out and displayed on the display unit 122.

When allocating the inspection time of the above-mentioned inspection equipment, if the number of construction subjects for which the process is set increases, the indicated workable period becomes shorter due to constraints, and it becomes impossible to secure the past actual construction period. Comes out. However, the order of equipment inspection is the inspection step, and the work mode is stored in the database 101 together with the main work order for each subject and the sub work order ID information classified into the work mode and the like via the work order control unit 130. Therefore, it is possible to flexibly respond to each adjustment item.

At this time, if the process chart creator sets the construction process beyond the feasible period indicated by the device, the constraint conditions for the exceeded portion are displayed on the screen. At the same time, if the cause of the restriction is other construction work, the display color of the bar chart of the corresponding construction work is changed to notify the schedule creator. The process chart creator considers countermeasures from the constraints displayed on the screen. The device displays a plurality of countermeasure candidates based on past results to help the process chart creator to consider countermeasures. The process chart creator searches for the work that interferes and the time when the work can be carried out while moving the process on the screen. When the implementation conditions are satisfied, the apparatus displays this and notifies the process chart creator, and the process chart creator sets the process.

Further, for example, when allocating the inspection time of the inspection device E, there may be a case where it is desired to allocate to a period other than the allottable period (assignable candidate) displayed on the display unit 122. When the inspection time of inspection time E is assigned during such a period, for example, the isolation conditions of other inspection equipment (for example, inspection equipment A) scheduled at the same time in the assigned inspection period, and There are factors such as interference with the work area conditions and other constraints not being met. The process chart creation function 112 displays this factor on the display unit 122.

This factor includes, for example, an event such as interference between the inspection device A and the work area performed at the same time in a part of the period in which the inspection device E is assigned. In such a case, the process chart creation function 112 displays on the display unit 122 the inspection process of the inspection device E, which can be performed even when the interference with the inspection device A occurs and does not occur, and when the interference occurs. Then, when the process chart creator avoids the problem of interference with the inspection device A in the work area by changing a part of the inspection period or changing the inspection process of the inspection device E, the inspection is performed under that condition. The inspection time of the device E can be assigned.

As described above, according to the periodic inspection process creation support device 100 of the present embodiment, a main process chart composed of critical processes is automatically generated, and for other inspection devices, the main process chart for each subject is passed through the work order control unit 130. By assigning the inspection time of each inspection equipment in the order displayed together with the sub-work order ID information classified into the work order and work form, even if you are not a skilled technician, the safety of the nuclear power plant is taken into consideration. It is possible to create a regular inspection process plan.

The actual regular inspection work is carried out based on the regular inspection process chart prepared in advance as described above. In the present embodiment, as shown in FIG. 1, a process monitoring unit 114 is provided in the process creation support unit 110, and the process monitoring unit 114 keeps the progress of the actual regular inspection work according to the regular inspection process chart. It is monitored whether or not it has progressed to.

FIG. 6 shows an example of a screen showing the progress of the regular inspection work. This progress monitoring is input for each process by the group that actually carries out the inspection work. The example shown in FIG. 6 is a process chart of the full-scale inspection process of the A system pump, and is roughly divided into preparatory work and pump disassembly. Is displayed or whether there is a delay. In the example shown in FIG. 6, it is shown on the bar chart that a process delay occurs in the bolt loosening in the pump disassembly process. In the actual screen, when a process delay occurs, it is indicated by a color display such as red.

The image shown in FIG. 6 can be viewed not only from the group that actually performs the inspection work but also from other groups (parallel or subsequent work group, etc.) that need to share information. Further, since each is linked with the main work order for each subject and the sub work order ID information classified into the work form, etc. via the work order control unit 130, the other groups are related to the inspection work of the own group. In the inspection work, it is possible to recognize in real time that a delay has occurred.

In such a case, it is necessary to warn the group of subsequent or related workers of risk information and the like. In the present embodiment, the main work order for each subject and the sub-work order ID information classified into the work form and the like are shared via the work order control unit 130 by the periodic inspection process creation support device 100 which is a common platform. This can be done to strengthen cooperation between each group. Furthermore, by recording the events, processes, and countermeasure results that occurred during the regular inspection, it can be used for analysis after the regular inspection, and know-how can be accumulated.

Therefore, as shown in FIG. 1, the periodic inspection process creation support device 100 is provided with the communication function 113, is connected to the network in the nuclear power plant, and each group member is a computer or a tablet terminal. The periodic inspection process creation support device 100 can be accessed via this network. That is, as shown in FIG. 7, in addition to the periodic inspection process creation support device 100, for example, a group A for operation management, a group B for maintenance, and groups C1, C2 ... Cn for performing actual inspection work are included in the network. Etc. are connected, and each group can access the periodic inspection process creation support device 100 to share information, and can also communicate via the communication function 113.

Each work item between the groups is given the main work order for each subject and the sub work order ID information classified into the work form, etc. via the work order control unit 130 of the periodic inspection process creation support device 100. Can be identified.

In addition, the communication function 113 includes a telephone function call and a real-time communication (chat) function using characters so that group members can communicate with each other. The communication between group members by this real-time communication (chat) function is recorded as characters together with the main work order for each subject and the sub-work order ID information classified into the work form, etc. via the work order control unit 130. It can be confirmed later, unlike calls made by Noh. Warnings to subsequent or related work groups such as the risk information mentioned above are given by, for example, chat.

In the database 101, maintenance information (subject, area risk, process), operation management information (management items and processes (including isolation work management)), and groups that perform actual inspection work are managed as inspection equipment data 103. Information to be performed (work subject, process, control item, attribute related to inspection, test, test run) is stored, and this information can be mutually confirmed by each group. This information can be displayed on the terminals of each group by selecting management items and attributes.

In addition, the periodic inspection process creation support device 100 can manage area / risk information and apply for maintenance / extension of work deadlines and the like via the communication function 113. In other words, parallel or subsequent work groups can link area risk information, request extension or adjustment of the deadline when interference occurs or the risk becomes high, and confirm the intention to the upper management. It has become. If the deadline is extended or adjusted, the inspection schedule will be changed and parallel or subsequent work groups will be contacted.

Here, FIGS. 8 and 9 show an example of displaying risk information in a certain area. FIG. 8 shows the risk information for the month x day, and FIG. 9 shows the risk information for the month △ day.

As shown in FIGS. 8 and 9, the risk information in the area is displayed, for example, in a color corresponding to the risk on a plan view of the reactor building. Regarding the work area and safety treatment measures, the height of the scaffold is represented by, for example, high (blue), medium (pink), and low (green). The scaffolding fall prevention points are indicated by a yellow frame, and the physical protection points are indicated by a green frame.

In FIGS. 8 and 9, for important equipment and systems, A system piping (20A / 150A), B system piping (20A), C system pool water level gauge, and A system tank are described.

In addition, in FIGS. 8 and 9, the colors actually attached to the image are represented by characters in parentheses such as (blue) and (black). Regarding the scaffolding, the scaffolding around the A-type tank is shown in pink, the scaffolding around the B-type pipe is shown in blue, and the central scaffolding is shown in green. In addition, the frame part described in yellow indicates the scaffolding fall prevention part, and the frame part described in green indicates the physical protection part.

Regarding important equipment and systems, in FIG. 8, the risk of the C system pool water level gauge is high and only shown in blue and R display, A system piping (20A / 150A), B system piping (20A), A. The system tank is shown in black. On the other hand, in FIG. 9, the A system piping (20A / 150A) and the A system piping (20A / 150A) have high risk and are shown in red and R, and the B system piping (20A) and the C system pool water level gauge are also risky. Is high and is indicated by blue and R indications. In addition to having the function of displaying colors in this way, if new restrictions, such as off-limits within 0 m, occur, they can be added.

FIG. 10 shows another display example of risk information. In FIG. 10, the letters (green), (yellow), and (red) shown in the table indicate the degree of risk, but in the actual display, the colors are displayed in yellow, red, and green instead of the letters. Indicates the degree of risk. In the example shown in FIG. 10, the risk states from July 1st to July 11th are shown for the decay heat removal function, the water injection function, the confinement function, and the power supply function. Regarding the confinement function and the power supply function, both indications are green, and the risk is low. Regarding the water injection function, all indications are yellow, and the risk is moderate. Regarding the anti-thermal heat removal function, it is red from July 8th to July 10th and is in a high risk state, and yellow in the other period and the risk is in a moderate state. In this way, the transition of risk in each function can be recognized from the display screen. It is also possible to confirm them together with respect to the examples shown in FIGS. 8 and 9.

The risk situation in each area changes depending on the inspection work carried out as described above. For example, in the risk of the area division of the controlled area, the place where the scaffolding was intended to be built is set as the C area for another work due to the process delay, or in the risk due to the dose rate, the process is delayed. These include cases where the main shield in the immediate vicinity has been removed by another work and the dose rate is high. By sharing this area / risk information through the periodic inspection process creation support device 100 together with the main work order for each subject and the sub-work order ID information classified into the work form, etc. via the work order control unit 130, the inspection work can be performed. When interference occurs or the risk becomes high when the extension is performed, it is possible to request other work groups or management groups to extend or adjust the deadline, and confirm the intention to the upper management. Can be done. In that case, the priority information given for each inspection given to the main work order (related to the critical path, important equipment, fire protection zone, flood boundary, dose rate, area classification of controlled area, etc.) It is possible to check the ones ranked according to the risk to be done at the same time, and it is possible to carry out the adjustment efficiently.

Similarly, it is possible to apply for maintenance / extension of the deadline for operation management (system operation, isolation management, etc.).

As described above, it is possible to grasp the group that performs other inspection work that affects the area and risk information, etc., and to easily adjust the deadline and apply for extension. Then, after the adjustment is completed, both maintenance and operation process corrections can be performed.

In addition, the regular inspection process chart created as described above (the regular inspection process chart before the start of work), the data related to the regular inspection process chart modified during the actual regular inspection work, and the information on the circumstances in which the revision was necessary. Is stored in the past regular inspection process actual data 105 of the database 101 after the regular inspection is completed, and the know-how regarding the regular inspection is accumulated in the database 101. As a result, the know-how gained from the regular inspection conducted this time can be utilized in the creation of the regular inspection schedule from the next time onward, and the regular inspection schedule can be created with higher accuracy.

In the above, the case of performing a regular inspection of one nuclear power plant has been described, but in reality, a plurality of nuclear reactors are installed in one power plant site, and a plurality of nuclear power plants are configured. Regular inspections may be conducted at the same time for these nuclear power plants. In such a case, in addition to isolation within one nuclear power plant, restrictions on work areas, etc., equipment to be used, artificial numbers required for work, etc. need to be considered as restrictions between each nuclear power plant. May occur. In such a case, it may be necessary to manage the regular inspection process in each nuclear power plant with one regular inspection process chart.

FIG. 11 shows an example of a regular inspection process chart when a plurality of nuclear reactors are installed in one power plant site as described above. In the example of the regular inspection process chart shown in FIG. 11, an example is shown in which regular inspections are performed on the three reactors A, B, and C at the same time. In the example of the regular inspection process chart shown in FIG. 11, information on the period during which the system is stopped (non-standby), information on the work during the system stop period to be carried out during the system stop period, information on the inspection time of the crane / lifting machine, and work Work regulation information that is prohibited to be implemented, for example, task-dependent information (constraint display) indicating information that B cannot be implemented unless A is completed when there are A work and B work, and inspections performed by government agencies Information etc. are included. In such a case, as described above, it is necessary to consider the equipment to be used, the artificial number required for the work, the above-mentioned government inspection, etc. as restrictions that cannot be carried out between the nuclear power plants at the same time.

From each work item of FIG. 11, it is possible to display the information of FIG. 8, 9 or 10 and vice versa.
