The input data recording unit 29 records the input data acquired by the first input data acquisition unit 28 (that is, the input data by the support staff 1 using the input device 17). The photographing recording unit 30 receives the output signal from the first input data acquiring unit 28, and converts the display screen of the display device 18 on which the plant behavior simulated by the simulating unit 25 is displayed into visual information (moving image data ) and recorded.

The functions of the simulator 20 configured as described above will now be described.
The simulating unit 25 simulates plant behavior based on the plant data obtained from the plant data obtaining unit 24 . The plant data output section 26 displays the plant data, which is the result of this simulation, on the display device 18 and simultaneously outputs it to the plant data recording section 27. The plant data recording section 27 records the plant data.

The support staff 1 in the accident countermeasure center 11 confirms the current state of the plant using the display device 18, and formulates accident countermeasures for resolving the accident that has occurred. Then, the support staff 1 uses the input device 17 to make a simulation operation request to the simulator 20 in accordance with the countermeasures against the accident. The input device 17 that receives the simulation operation request from the support staff 1 outputs this request to the first input data acquisition section 28, and this first input data acquisition section 28 outputs the request to the simulation section 25. . The simulation unit 25 performs a simulated calculation (accident response simulation) in response to a simulation operation request from the support staff 1 based on the accident response measures described above.

As described above, the data recorded in the plant data recording unit 27, the input data recording unit 29, and the photographing recording unit 30 are initialized by the support staff 1 in the accident control center 11 using the input device 17. When input to the input data acquisition section 28, it is initialized by the output from the first input data acquisition section 28. FIG.

More specifically, the information processing unit 21 described above receives input operation data input to the simulator 20 using the input device 17 by the support staff 1 based on the accident countermeasures, and simulates the simulator 20 based on the input of this input operation. The plant data, which is the result of the simulation performed by the unit 25, and the moving image data from the photographing recording unit 30 are processed to create the operating procedure manual 3. The information processing section 21 includes a simulator record acquisition section 31 , a second input data acquisition section 32 , a creation section 33 and an output section 34 .

The simulator record acquisition unit 31 acquires plant data, which is a simulation result, from the plant data recording unit 27 and input data by the support staff 1 from the input data recording unit 29 . The second input data acquisition unit 32 inputs each request of the support staff 1 as input data through the input device 17 and outputs the input data to the creation unit 33 .

The creation unit 33 extracts the input data from the second input data acquisition unit 32 based on the plant data, which is the simulator result from the simulator record acquisition unit 31, the input data by the support staff 1, and the video data from the shooting recording unit 30. The operation procedure manual 3 is created in response to the operation procedure manual 3 creation request. The output unit 34 outputs the operating procedure manual 3 created by the creation unit 33 to the display device 18 and the output device 19 .

When the creating unit 33 creates the driving operation procedure manual 3, the support staff 1 requests the creation of the driving operation procedure manual 3 via the second input data acquisition unit 32, and selects the information format of the driving operation procedure manual 3. specified. That is, the information form of the operation procedure manual 3 is a form that the plant operator 2 in the operation room 12 can easily and reliably understand. For example, the information format of the operation procedure manual 3 is a document that conforms to the procedure manual that the plant operator 2 is familiar with, a moving image that shows the input operation of the support staff 1, or a display device 18 It is a moving image showing the simulation result of the plant behavior displayed on the display screen of . The driving procedure manual 3 is created by combining these two types of moving images and documents according to the situation.

The functions of the information processing section 21 configured as described above will be described below.
When the simulating unit 25 of the simulator 20 simulates the plant behavior based on the accident countermeasures and the simulation results show that the accident is converged, the simulator record acquiring unit 31 of the information processing unit 21 acquires plant data records. The plant data, which is the simulation result, from the unit 27 and the input data from the input data recording unit 29 are acquired and output to the creation unit 33 .

Based on the above-described data from the simulator record acquisition unit 31 and the moving image data from the shooting recording unit 30, the creation unit 33 generates the driving operation manual 3 input to the second input data acquisition unit 32 using the input device 17. Based on the input data of the creation request, the operating procedure manual 3 is created in the specified information format. The output unit 34 outputs the operating procedure manual 3 created by the creation unit 33 to the display device 18 for display.

The support staff 1 confirms the operating procedure manual 3 displayed on the display device 18, and if they want to change the information form of this operating operating procedure manual 3, or if they want to edit or add the contents of the operating operating procedure manual 3, uses the input device 17 to input a correction request for the operating procedure manual 3 to the second input data acquisition unit 32 as input data. The second input data acquisition unit 32 outputs a request for correction of the operating procedure manual 3 to the creating unit 33, and the creating unit 33 creates the operating procedure manual 3 reflecting the correction request.

The operation procedure manual 3 reflecting the correction request is displayed on the display device 18 by the output unit 34, and the support staff 1 who has confirmed this next follows a predetermined output device 19 (e.g. A request for output destination setting for setting the output device 19) and a request for output of the operating procedure manual 3 to the output device 19 of the set output destination are sent to the second input data acquisition unit 32 using the input device 17. input. Based on this input data, the output unit 34 outputs the operating procedure manual 3 to a predetermined output device 19 .

Next, the step of examining accident countermeasures against an accident that occurred in a plant, for example, an unexpected accident, and the step of creating the operation procedure manual 3 will be described with reference to FIG.

First, the support staff 1 in the accident control center 11 issues an activation request to the simulator 20 of the server 16 (S1). As a result, a screen for monitoring main parameters (plant data) of the entire plant, a screen for monitoring more detailed parameters for each system, and a simulator operation screen are displayed on the display device 18 (S2).

In this state, the support staff 1 starts considering countermeasures (accident countermeasures) for the accident that occurred (S3). The support staff 1 instructs the plant data recording unit 27 and the input data recording unit 29 of the simulator 20 to start recording, and the photographing recording unit 30 to start photographing and recording, respectively, when the accident countermeasures are determined. (S4), and according to this instruction, the plant data recording unit 27, the input data recording unit 29 and the photographing recording unit 30 start recording and photographing (S5).

Further, the support staff 1 uses the input device 17 to input an operation based on the determined accident countermeasures to the first input data acquisition section 28 of the simulator 20 (S6). The first input data acquisition unit 28 acquires input data from the input device 17 (S7), outputs the input data to the simulation unit 25 to execute a simulation (S8), and inputs data recording unit 29 for recording (S9).

The plant data, which is the result of the simulation performed by the simulating section 25, is output and displayed on the display device 18 by the plant data output section 26 (S10), and is also output and recorded by the plant data recording section 27 (S11). . While confirming the simulation result displayed on the display device 18 (S12), the support staff 1 continues the input operation as necessary. The plant data recording unit 27, the input data recording unit 29, and the photography recording unit 30 also continue recording and photography.

If the accident does not come to an end after all the accident countermeasures have been completed, if other appropriate accident countermeasures are found, or if an input error is found in the input operation, the support staff 1 will contact the plant data recording unit. 27, the input data recording unit 29 and the photography recording unit 30 are instructed to finish recording and photography (S13), and the plant data recording unit 27, the input data recording unit 29 and the photography recording unit 30 are initialized. Then, the process returns to step S3 to review the accident countermeasures again.

The plant data recording unit 27, the input data recording unit 29, and the photographing recording unit 30 complete recording and photographing in accordance with the instruction in step S13 (S14), are initialized and enter a state before recording and photographing start, and proceed to step S2. return.

Even if the support staff 1 can judge that the accident will be settled by the simulation result of the simulation unit 25 at the stage where the accident countermeasures have been completed, the plant data recording unit 27, the input data recording unit 29, and the photographing recording unit 30 is finished (S13), and then the information processing section 21 is instructed to create the driving operation manual 3 (S15).

The instruction to create the operating procedure manual 3 in step S15 is given by the support staff 1 using the input device 17 to input a request to create the operating procedure manual 3 to the second input data acquisition unit 32 . At this time, the support staff 1 selects and instructs the information format of the operating procedure manual 3 from among three types of documents, moving images, or a combination thereof. The preparation unit 33 of the information processing unit 21 prepares the driving operation procedure manual 3 in a designated information format according to the instruction from the support staff 1 via the second input data acquisition unit 32 (S16). The operating procedure manual 3 created by the creation unit 33 is output and displayed on the display device 18 by the output unit 34 (S17).

The support staff 1 confirms the driving operation manual 3 displayed on the display device 18 (S18), and if necessary, uses the input device 17 to request corrections such as editing, addition, etc., and changes in the information format. (S19). The second input data acquisition unit 32 outputs a request for correction or the like from the support staff 1 to the preparation unit 33, and the preparation unit 33 corrects the operating procedure manual 3 according to the request (S20). The output unit 34 outputs the operating procedure manual 3 reflecting this correction to the display device 18 (S21).

After the support staff 1 confirms the operation procedure manual 3 in which the correction is reflected on the display device 18 (S22), a predetermined output device 19 (for example, the output device 19 installed in the operation room 12) is set. The input device 17 is used to issue a request for prior setting and a request to output the operating procedure manual 3 to the predetermined output device 19 (S23). In response to this instruction, the output unit 34 outputs the operation procedure manual 3 created by the creation unit 33 and confirmed by the support staff 1 to a predetermined output device 19 (for example, the output device 19 in the operation room 12). (S24). As a result, for example, the operation manual 3 is shared between the operation room 12 and the accident countermeasure center 11 .

With the configuration as described above, according to the first embodiment, the following effects (1) and (2) are obtained.
(1) The support staff 1 of the accident countermeasure office 11 formulates an accident countermeasure, and inputs an input operation based on this accident countermeasure to the simulation unit 25 of the simulator 20 using the input device 17, thereby simulating. Part 25 simulates the behavior of the plant. These procedures (formulation and simulation) are repeatedly tried until the simulation result of the simulation section 25 converges on the accident. Then, the plant data of the simulation result and the input data of the input operation at the time of convergence of the accident are processed by the creation unit 33 of the information processing unit 21 together with the moving image data from the shooting recording unit 30, so that the operation procedure manual 3 is created. be done.

As a result, in the event of a plant accident, particularly an unexpected plant accident, the accident countermeasures center 11 can efficiently study accident countermeasures using the simulator 20, and the information processing unit 21 can provide detailed operation procedure manuals 3 can be created. As a result, since the plant operator 2 in the operation room 12 can use the detailed operating procedure manual 3, it is possible to reduce variations in the accident response level of the plant.

(2) The operation procedure manual 3 created by the creation unit 33 of the information processing unit 21 is created in a form that the plant operator 2 in the operation room 12 can easily and reliably understand. For example, the plant operator 2 is in the form of a document in accordance with the procedure manual that they are familiar with, the video form of the support staff 1 performing a simulation operation, etc., and the behavior of the plant displayed on the display device 18. The operating procedure manual 3 is created in the form of a moving image of the plant data representing the simulation results, or in a form in which these forms are combined.

By creating the driving operation procedure manual 3 as a document, it is possible to prevent the driver from missing or erroneously hearing the voice instructions. In addition, by creating the operating procedure manual 3 as a moving image, it is possible to convey information, which is difficult to express clearly in a document, as visual information. By selecting and setting the information format of the operation procedure manual 3 according to the situation as described above, in particular, the plant operator 2 in the operation control room 12 can receive complicated operation instructions of the operation procedure manual 3. , can be transmitted more accurately.
