Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel exchange work support device for inferring optimum operation of fuel removal, loading, and rearrangement in a fuel refueling operation of a nuclear reactor and instructing the operator of the result. It is about.

[0002]

2. Description of the Related Art In a nuclear power plant, a large number of fuels are exchanged during periodic inspections and planned outages. Especially in the refueling work at the new converter "Fugen" power plant,
It uses four types of transfer equipment: a fuel in / out machine, a transfer chute, and a fuel transfer machine.
And important items such as fuel are sequentially handled between the spent fuel storage pool. This work is performed by remote control from the main control room almost in parallel.

The efficiency of refueling work greatly affects the process of refueling work. For example, the process expands and contracts depending on whether the fuel inlet / outlet machine is used to remove an article from a refueling machine or an article from a transfer chute. Conventionally, such judgments are all made by an experienced operator.

In addition to fuel, the articles handled include shield plugs and seal plugs. It is necessary to manage the location and movement of each of these items one by one, and work such as filling out forms and checking data is performed while looking at the operating procedure manual.

[0005]

As described above, it is difficult for an inexperienced operator to operate the four types of transfer equipment in parallel and efficiently in order to efficiently operate them. In addition, it requires a considerable amount of work to fill out forms and check data for each operation of each device, and it is extremely nervous to manage hundreds of important items without mistakes. It was a work to use.

Further, since a wide variety of transfer facilities and handling items are required, it takes a considerable time (about one month for a skilled worker) to prepare a refueling work plan.

The object of the present invention is to solve the above technical problems, to reduce the burden on the operator, to improve the safety, to optimize the work process, and to save the labor of article management. It is to provide a replacement work support device.

[0008]

SUMMARY OF THE INVENTION The present invention is directed to a network model relating to refueling equipment, a knowledge database of refueling work systematizing the experience of skilled operators, and a planning database for carrying out individual refueling work. And an article location database that holds the location of each article, a central processing unit that applies the data of each database to the network model based on the set conditions, and infers the optimal fuel exchange work, and the inference result It is a refueling work support device including output means for instructing an operator of a work procedure, input means for inputting an operation result of an operator, and printing means for outputting the input result as a form.

[0009]

In the present invention, an electronic computer is used to represent the interrelationships of refueling equipment as a network and the experience of the operator as many rules.
The operator is instructed on the optimum operating procedure, and the device data for each operation is input to the electronic computer to manage the articles and output the necessary forms.

EXAMPLE FIG. 1 shows the basic structure of the fuel exchange equipment of the new converter "Fugen". In the refueling work, the fuel is taken out of the nuclear reactor 11 by the refueling machine 12.
The taken fuel is transferred to the fuel exchange pool 13. In the fuel exchange pool 13, fuel is handled using the fuel inlet / outlet machine 14. The transfer chute 15 transfers the fuel to the spent fuel storage pool 16. The movement of the articles in the spent fuel pool 16 is performed using the fuel transfer device 17. The loading of fuel is in the opposite direction, and the spent fuel pool 1
6, toward the fuel exchange pool 13 and the nuclear reactor 11, using a fuel transfer machine 17, a transfer chute 15, a fuel inlet / outlet machine 14, and a fuel exchange machine 12. In FIG. 1, solid arrows indicate fuel loading and dashed arrows indicate fuel removal.

FIG. 2 shows a basic configuration and a utilization state of the refueling work support device according to the present invention. In this device, a network model 22 relating to a fuel exchange facility, which represents a refueling operation in which a wide variety of various transport facilities and handled goods are congested in an electronic computer, and the experience of experienced operators are collected and systematized into about 150 rules. A knowledge database 23 of refueling work and a plan database 24 for carrying out individual refueling work are stored. In the central processing unit (computer main body) 21, the data of each database is applied to the network model based on the set conditions, and the optimum fuel exchange work procedure is performed so that the fuel exchange work can be carried out smoothly and in the shortest time. Infer. Then, the operating procedure based on the inference result is instructed to the operator on the screen of the CRT device 25. The operator actually operates the control panel 26 based on the instruction. The fuel handling facility 27 is operated by a signal from the control panel 26.

The operator specifies the start time, the end time, and the device data to be recorded for each operation, using the keyboard and mouse 2.
Use 8 to enter. By this input, each operation result is transmitted to the central processing unit 21, and the article location database 29 that stores and holds the location status of each article is changed. Further, the driving operation result and the article management status are output from the printing device 30 as a form.

An example of the display on the screen of the CRT device is shown in FIG. The portion (1) is an operation instruction screen for instructing the operator to operate, and 12 operation names are displayed in the order of operation. The parts (2), (3), and (4) are operation result input screens in which the operator inputs the detailed contents of each operation item and the operation start time, end time, and necessary data are input by the operator. ..
(2) Input the operation result of the fuel in / out machine, (3) the operation result of the fuel transfer machine, and (4) the operation result of the fuel exchanger. Depending on the specification, the operation result of the transfer shoot is (1) ~
It can be performed at any position of (4). CR
On the screen of the T device, the next operation result input screen is displayed every time one operation is completed for one device.
The operator can perform an optimum fuel exchange operation by looking at the operation instruction screen and performing a predetermined operation in accordance with an instruction from the central processing unit and sequentially inputting necessary data on the operation result input screen.

Regarding the management of the articles, the arrangement of the articles can be confirmed on the screen as shown in the core state display of FIG. 4, for example. Further, past operation records and movement history of each article can be output by the printing apparatus shown in FIG.

Further, the present apparatus is provided with a guidance function for instructing an operating procedure and confirmation items to an operator in actual operation, and a facility diagnostic function for judging the validity of the operation based on past data and related parameters.
