Description

  Embodiments described herein relate generally to an inspection technique for a fuel changer control device that replaces fuel assemblies and control rods of a nuclear power plant.

At the end of the operation period, the nuclear power plant removes fuel assemblies with high burnup from the core and transfers them to the fuel storage pool, or repositions fuel assemblies with different burnup depending on the loading position of the core. Or, the same number of fuel assemblies as those taken out from the core are newly loaded and the operation cycle is rotated.
In this way, the fuel changer control device that automatically controls the crane that transports the fuel assembly inputs the coordinate data of the loading position (gripping position) of the transfer source and the loading position (release position) of the transfer destination. (For example, patent document 1).
The gripping position and the releasing position, which are coordinate input by the worker, are confirmed by changing the state of the symbol at the corresponding position on the horizontal cross section of the core displayed graphically on the monitor.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
As shown in FIG. 1, the inspection apparatus 10 (hereinafter referred to as the inspection apparatus 10) of the fuel changer control apparatus 30 is a fuel replacement that moves the fuel assembly 42 (FIG. 3) or the control rod 43 while holding it with a crane. A first remote display unit 11 for remotely displaying a setting input form (FIG. 2) of the first interface 31 of the machine control device 30, and sequence information 15a describing a gripping position and a releasing position in a series of operations of the crane according to the operation order. A sequence information generating unit 14 to be generated, a setting input unit 16 for setting and inputting a gripping position and a releasing position of the sequence information 15a according to a work order on a setting input form (FIG. 2) remotely displayed on the first remote display unit 11; The grabbing position 44 and / or the releasing position 45 set and input to the fuel changer control device 30 are graphically displayed on the second interface 32. The second remote display unit 12 for remotely displaying the loaded loading position form (FIG. 3), and the loading position form remotely displayed on the second remote display unit 12 at each timing of setting input in the setting input unit 16 And a display capture unit 17 for capturing in synchronization.

The fuel changer control device 30 controls the operation of a crane (not shown) installed in the upper part of a reactor pressure vessel (not shown) on site.
This crane grips a fuel assembly 42 or a control rod 43 loaded on a core 41 (see FIG. 3) partitioned by a grid-like lattice, and these are held in the vertical direction (the display surface vertical direction in FIG. 3) and horizontally. It is moved in the direction (direction parallel to the display surface in FIG. 3).
The position where the fuel assembly 42 or the control rod 43 is loaded in the core 41 is defined based on the loading position information 13 (13a, 13b) which is basic design information.

The fuel changer control device 30 includes a first interface 31, a second interface 32, and an execution command output unit 35.
The first interface 31 downloads the setting input form (FIG. 2) from the screen form storage unit 34 and displays it on the operation screen.

In this setting input form (Fig. 2), the coordinates of the gripping position (movement source position) where the crane gripper performs the gripping operation and the coordinates of the release position (movement destination position) where the crane gripping part performs the release operation are input. There are provided input areas 36 (36a, 36b) and buttons 38 for confirming and canceling these coordinate inputs.
The operator of the refueling machine control device 30 designates the input area 36 and the button 38 with the cursor 37 appearing on the setting input form (FIG. 2) and executes the operation.

The second interface 32 downloads the loading position form (FIG. 3) from the screen form storage unit 34 and displays it on the operation screen.
The loading position form (FIG. 3) is a graph of the horizontal cross section of the core 41, and the fuel assembly 42 (FIG. 3) or the control rod 43 is controlled by a coordinate system linked to the loading position information 13 (13a, 13b). The loading position is specified.

Coordinate data represented in the coordinate system of the loading position form (FIG. 3) is input to the input area 36 (36a, 36b) of the setting input form (FIG. 2).
When coordinate data is input to each of the input areas 36 (36a, 36b) and the confirm button 38 is pressed, the coordinate data is transmitted to the execution command output unit 35.

The execution command output unit 35 outputs an execution command for automatically operating the crane based on the installed program, the coordinate data transmitted from the first interface 31, and the loading position information 13a.
Further, the execution command output unit 35 further transmits the coordinate data transmitted from the first interface 31 and used to generate the crane execution command to the second interface 32.
As a result, the graphic of the corresponding loading position in the loading position form (FIG. 3) changes to a symbol indicating the grip position 44 or the release position 45.
In FIG. 3, the state change of the symbol is shown for the grip position 44 or the release position 45 related to the loading position of the fuel assembly 42, but the state of the symbol can be similarly changed for the control rod 43.

In the embodiment, the inspection apparatus 10 includes the first inspection apparatus 10a directly connected to the first interface 31 and the second inspection apparatus 10b directly connected to the second interface 32. You can also.
These inspection apparatuses 10 (10a, 10b) can be realized by a general-purpose personal computer.

The first remote display unit 11 remotely accesses the fuel changer control device 30 and remotely displays the setting input form (FIG. 2) displayed on the first interface 31.
Then, the first remote display unit 11 operates the cursor 37, the input area 36 (36a, 36b), and the button 38 of the setting input form (FIG. 2) on the inspection apparatus 10a side to change the coordinate data into the fuel replacement. It can be transmitted to the execution command output unit 35 of the machine control device 30.

The sequence information generation unit 14 rewrites the work order of the gripping position 44 and the release position 45 described based on the loading position information 13 based on the coordinate system of the loading position form (FIG. 3).
Further, the sequence information generation unit 14 generates sequence information 15a obtained by converting this work order into a series of operation data for the cursor 37, the input area 36 (36a, 36b) and the button 38 in the setting input form (FIG. 2).

When all the fuel assemblies 42 and the control rods 43 are inspected, there are thousands of input patterns on the setting input form (FIG. 2).
For this reason, the sequence information 15a is configured such that such an enormous number of input patterns can be sequentially set in the setting input form (FIG. 2) according to the inspection order.

The setting input unit 16 automatically inputs the coordinate data of the gripping position 44 and the release position 45 described in the acquired sequence information 15a sequentially and sequentially on the setting input form (FIG. 2) according to the work order.
Each time the coordinate data is input to the input area 36 (36a, 36b) of the setting input form (FIG. 2) by the setting input unit 16 and the button 38 is pressed, the loading position form (FIG. 2) displayed on the second interface 32 is displayed. In 3), the positions of the symbols indicating the grip position 44 and the release position 45 are updated.

The second remote display unit 12 remotely accesses the fuel changer control device 30 and remotely displays the loading position form (FIG. 3) displayed on the second interface 32.
The display capture unit 17 captures the loading position form (FIG. 3) remotely displayed on the second remote display unit 12 in synchronization with individual timings of setting input in the setting input unit 16.

That is, image data obtained by hard-copying a plurality of loading position forms (FIG. 3) corresponding to the input patterns of the plurality of setting input forms (FIG. 2) is obtained.
The image data of the plurality of loading position forms (FIG. 3) obtained in this way is sequentially stored in the storage unit 18.
By this. Even when the number of input patterns of the setting input form (FIG. 2) is enormous, the image data of the corresponding loading position form (FIG. 3) can be automatically acquired within a short period.

The image data of the loading position form (FIG. 3) stored in the storage unit 18 may employ a file name related to the input coordinate data to the setting input form (FIG. 2).
For this purpose, it is assumed that the shutter signal S transmitted from the setting input unit 16 to the display capture unit 17 incorporates the coordinate data input to the corresponding loading position form (FIG. 3) as information.

  The position identifying unit 19 reads the image data of the loaded position form (FIG. 3) that is captured and accumulated in the accumulating unit 18, and identifies the position of the symbol on which the gripping position 44 and / or the releasing position 45 are graphically displayed. .

FIG. 4 exemplifies the element symbols constituting the graphic of the core horizontal section in the loading position form (FIG. 3).
As described above, the element symbols constituting the graphic of the core horizontal cross section are represented as a collection of RGB light emitting pixels.
Therefore, the coordinate data of the grip position 44 and the release position 45 displayed on the loading position form (FIG. 3) can be identified based on the shape and color of the pixel aggregate constituting the symbol.

  The determination unit 21 determines whether the setting input of the first interface 31 matches the identification position in the graphic of the second interface 32 in light of the sequence information 15b. That is, it is possible to make a determination regarding match / mismatch from the storage order (or file name) of the image data of the loading position form (FIG. 3) sequentially stored in the storage unit 18 and the position information of the symbol in the graphic. it can.

The recording table generation unit 22 generates a table (FIG. 5) in which the determination results for all the gripping positions 44 and the release positions 45 in a series of operations are recorded.
As shown in FIG. 5, the recording table includes inspection items in which crane operation targets (fuel assemblies 42 or control rods 43), operations (gripping, pulling out, releasing), and coordinate data are described, and in each inspection item. The judgment result (good / bad) and the judgment time of each inspection item are described.

The loading position form (FIG. 3) is registered in the storage unit 18 in association with the inspection item of the recording table (FIG. 5).
Thereby, when the cursor is set to a specific inspection item on the recording table (FIG. 5), the corresponding loading position form (FIG. 3) can be displayed in a pop-up manner.
Such a recording table can be viewed on a display unit (not shown) of the inspection apparatus 10 and can be output as an inspection report.
This makes it easier to refer to it at a later date, leaving evidence of the inspection work.

If there is a defect in the determination result of the recording table (FIG. 5), it means that the program installed in the execution instruction output unit 35 has a problem.
Therefore, in such a case, the program is corrected, reinstalled in the execution instruction output unit 35, and re-examination is performed based on the sequence information 15a.
In this case, if all the coordinate data described in the sequence information 15a are automatically automatically input from the beginning to the setting input form (FIG. 2), the processing time becomes enormous.

Therefore, the setting input unit 16 designates an inspection item that is a defect determination result among a plurality of items described in the sequence information 15a, and sets and inputs the gripping position and the release position.
As a result, only the loading position form (FIG. 3) corresponding to the designated inspection item is captured as image data and is subjected to determination again.
Then, the generation unit 22 overwrites and records the determination result of the inspection item specified by the setting input unit 16 in the table (FIG. 5).
As a result, even if a defect determination result is found in the first inspection and the program is corrected, it is not necessary to repeat the inspection from the beginning, and the inspection period can be shortened.

The operation of the inspection apparatus will be described based on the flowchart of FIG.
The first inspection device 10a is connected to the first interface 31 of the fuel changer control device 30 to display the setting input form (FIG. 2) remotely (S11), and the second inspection device 10b is connected to the second interface 32. To remotely display the loading position form (FIG. 3).
On the other hand, the sequence information 15 describing the gripping position and the releasing position input to the setting input form (FIG. 2) according to the work order is generated (S12).

In the setting input form (FIG. 2) displayed remotely, the setting position 44 and the release position 45 of the sequence information are set and input according to the work order (S13).
Then, a loading position form (FIG. 3) in which the setting input position of gripping position 44 and / or releasing position 45 is displayed on the second interface 32 is remotely displayed on the second inspection apparatus 10b (S14).

Then, the graphic of the loading position form (FIG. 3) displayed remotely is captured in synchronism with the timing set and input on the setting input form (FIG. 2) (S15).
Further, the symbols of the grip position 44 and the release position 45 included in the captured graphic are identified (S16).

If the grip position 44 and the release position 45 identified as the symbols match the coordinate data described in the corresponding order of the sequence information 15b (S17: Yes), the table (FIG. 5) is determined as good. If it is recorded (S18, S20) and does not match (S17: No), it is recorded in the table (FIG. 5) as a failure determination (S19, S20).
The inspections from S13 to S20 are repeated until the last inspection item (S21: No, Yes), and the table (FIG. 5) is output as the inspection result (S21).

Here, in the table (FIG. 5), when there is an inspection item whose determination result is defective (S23: Yes), there is a defect in the program that controls the execution command output unit 35 of the fuel changer control device 30. It turns out that.
Therefore, this program is modified (S24), only the inspection items corresponding to the defect setting input in the sequence information are specified (S25), and the flow from (S13) to (S22) is executed. If all goes well, the inspection ends (S23: No, END).

Note that when all the input patterns of the thousands of setting input forms (FIG. 2) are inspected, the processing takes time, so that the table (FIG. 5) is synchronized with the time (S22) when the table (FIG. 5) is output. The notification mail may be transmitted to a predetermined address.
Further, even when the process is stagnant and a timeout is detected, a notification mail that a failure has occurred may be transmitted to a predetermined address.

  According to the inspection apparatus for the fuel changer control device of at least one embodiment described above, an additional function is implemented in the execution program of the fuel changer control device by remotely accessing the fuel changer control device. Inspection can be automated without any problems.

These embodiments can be implemented in various other forms, and various omissions, replacements, changes, and combinations can be made without departing from the scope of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalents thereof.
In addition, the constituent elements of the inspection device of the fuel changer control device can be realized by a processor of a computer, and can be operated by the inspection program of the fuel changer control device.
