Description

The present invention relates to periodic inspection support in a nuclear power plant.

FIG. 1 is an overview diagram related to a conventional periodic inspection. The main points that require periodic inspection are the control rod (6) in the reactor building (2), the measuring device (7), and the reactor pressure vessel (4) containing the nuclear fuel. The double-ended arrows indicate how the signals go and go.
Control of the operation of the nuclear reactor or the like is performed in the adjacent central control room (1). The central control room (1) has a plant integrated control device (3), and there are various operation buttons on the panel. The plant integrated control device (3) sends a signal to a control machine (6) such as a control rod in the reactor building (1) or receives a signal from the measuring device (7) to monitor a reactor operation state. .
At the time of periodic inspection, various periodic inspection devices (8) are brought into the reactor building from the door (9).
Process management, such as the progress of periodic inspections, is carried out by a periodic inspection management computer (11) placed in a building on the reactor power plant site. A large number of LAN personal computers (12) are LAN-connected to the periodic inspection management computer (11).
A regular inspection process for a conventional boiling water reactor is shown in FIG. 2 (Non-Patent Document 1).
Periodic inspections are judged by the auditing body approved by the supervisory body, and then passed or rejected. In detail, as shown in FIG. 3, it is shown as an example (non-patent document 2) of the periodic inspection content description table. It covers a wide variety of areas, such as shipping inspections that check for leaks through the fuel rod hair, disassembly and maintenance of safety valves, operation tests, and diesel engine appearance inspections.

Recently, various regulations relating to nuclear power plants have changed, and even if the quality under new conditions deteriorates over time, the nuclear power plants can be operated if the required functions and quality can be maintained. However, when defects are detected by periodic inspections, etc., repair work is required, the inspection itself is required to be rigorous and reported to relevant places, and in some cases it has become strict to apply and obtain permission. . It has become important not to perform construction or change or repair parts without permission.
Even if it is an examination by a third party examination organization, the subjectivity of the examiner is included. This is different from the judgment of the nuclear power plant owner. If both sides do not agree, it is possible that power generation will stop for a long time.
The subjectivity of both the examiner and the owner of the nuclear power plant is eliminated as much as possible, and if there is a difference in opinion, it is impossible to generate electricity unless the examination passes. It is necessary to promptly provide such judgment materials (such as supervisory bodies) that can be quickly judged and understood by both parties.

As shown in FIG. 4 as an example, the periodic inspection content description table in the present invention inspects the inspection of the equipment j of the electric work i by attaching the serial number as i for the electric work and the number as j for the equipment. (I, j), which makes it easier to manage. The period diagram showing the progress of the inspection of the electric workpiece shown in FIG. 5 is created with reference to the previous periodic inspection process diagram regarding the electric workpiece. The period diagram indicating the progress of the inspection of the equipment belonging to the electric workpiece i shown in FIG. 6 is created with reference to the previous periodic inspection process diagram regarding the equipment belonging to the electric workpiece i.
FIG. 7 is an overview diagram relating to the periodic inspection support apparatus of the present invention. Thick lines in the figure indicate connections such as wireless and optical cables for information transmission.
The apparatus of the present invention is connected to the new periodic inspection control computer (11 1) of the present invention via a LAN, the camera 1 (121) carried in to monitor the periodic inspection in the central control room (1), and the reactor building (2) Camera 2 (131) and periodic inspection device (8) for monitoring that can be carried in at the time of periodic inspection, and a loading / unloading control device (140) that is installed at the time of periodic inspection, and LAN connection with bracket power key It consists of an S personal computer (114), a LAN connected Si personal computer (115) with a metal power key, and a LAN connected Sij personal computer (116). The externally connected personal computer is an externally connected SS personal computer (113) with a metal power key.
The camera 1 (121) monitors and records a control rod operation confirmation test and the like performed in the plant integrated control device (3) in the central control room (1).
The carry-in / out control device (140) comprises a carry-in / out control computer (141) connected to the new periodic inspection control computer (11) via a LAN, a carry-in / out monitoring camera 3 (142), and a gate (143). The output control computer (141) connects the gate (143) and the camera 3 (142) via LAN, reads the records from the IC tag attached to the periodic inspection-related materials, and compares the weight and shape of the actual product with the gate (143). Open / close control is automatically performed, and the situation is monitored and recorded by the camera 3 (142).
By connecting the periodic inspection device (8), which is carried into the reactor building (2) during the periodic inspection, to the new periodic inspection control computer (11 1) via a LAN, the new periodic inspection control computer (11 1) can be connected to an electric power company and a third party. The inspection standard is controlled by comparing the built-in inspection standard that has been agreed with the general inspection organization and the measured value of the periodic inspection device (8) inspection, and this situation is monitored and recorded by the camera 2 (131).
The periodic inspection is controlled by the above equipment that is connected to the LAN with the software built in the new periodic inspection control computer (11). In particular, the work order is controlled from the time when processing is performed or the time when transmission / reception is performed. If the pre-processing is not completed by checking a prescribed electronic signature or the like, post-processing is restricted and a warning is issued.

Since the electric company and the third-party examination organization have agreed to the computer the examination standards that have been agreed upon, it is difficult for human judgments such as speculation to enter the examination results and examination results.
Since the inspection status is monitored and recorded by the camera, the inspection is less likely to be falsified and becomes evidence later.
The person in charge only needs to perform his / her own duties, and he / she does not have to worry and is less tired and less mistakes. Periodic inspection is performed quickly and reliably, management costs are reduced, and power generation costs are reduced.
In carrying out the inspection work this time, it becomes possible to perform image training by looking at the recording of the previous periodic inspection, thereby reducing work mistakes and improving work efficiency.
Even if the screening side has an error or oversight, the screening time will be inadvertently spent due to damages such as compensation, and the screening will proceed quickly because there will be less demand for pass / fail.
In order to eliminate the possibility that the management of the auditing organization will suffer damage due to excessive auditing by the auditors, the management of the auditing organization will have the right to instantaneous personnel and the final final auditing right to the auditor, and the supervisory authority will manage the auditing organization. It will give a sense of security to the electric utility to be judged.

Other Example 1

A wide-angle lens that monitors the entire liquid level of the reactor pressure vessel (4) when performing periodic inspection by opening the lid in the reactor pressure vessel (4) that encloses and burns the nuclear fuel in the reactor building (2) A monitoring device comprising one 8mm camera with a reactor and a reactor pressure vessel (4) several regular lens 8mm cameras that monitor the whole liquid level with several units and a recording device. In order to monitor the fall of the foreign matter, the liquid surface ripple is monitored.
It is difficult to confirm the fall of small objects. However, if it is a ripple, it can be confirmed that there was a fallen object because the sign remains large and long. The time and the approximate position of the ripples are identified from the recording of the 8mm camera with a wide-angle lens, and the fallen object can be identified by playing back the recording of the normal lens 8mm camera several seconds before.
During the period when the reactor pressure vessel (4) is not inspected after the reactor pressure vessel (4) is opened, a plastic transparent lid or a reactor pressure vessel is used to prevent falling objects to the reactor pressure vessel (4). Put a transparent cover about 2m high around (4).
Observation of the reactor pressure vessel (4) is performed by remotely operating a self-propelled normal telephoto camera or a self-propelled underwater telephoto camera in order to prevent an object from falling from an inspector's pocket or the like.

Component performance degrades over time. If a given performance can be maintained, it can continue to be used. Periodic inspections must be rigorous according to maintenance standards. If you do it efficiently, the cost will increase. The inspector becomes conservative and shrinks. Since the person in charge only needs to work in accordance with the control of this apparatus, it is unnecessary to take extra care and do not get tired.
Electric power companies have become free from power supply obligations due to the liberalization of electric power and are allowed to pursue profits alone. Currently, electric power companies have a wide range of management including thermal power, nuclear power, wind power generation, power distribution, distributed power supply sales, and telecommunications business. It may be more efficient to become a specialized company that only sells non-nuclear power and be criticized to an anomaly, or an existing nuclear power company to purchase in bulk. By adopting this equipment by a specialized company, there will be no omissions in procedures and communication in equipment management inspection, and efficiency will be improved. By adopting this device with efficient electronic trading features, power generation costs will not increase even if one company has one power plant. Moreover, even if there is a defect in the inspection, it is a defect of the device, and it is less likely to hurt employees because it can be improved with the advice of the external committee. In particular, if the president resigns for each scandal, human resources will be exhausted. It is possible to protect human resources that become scarce as you go upstream.
