Description

  The present invention relates to a nuclear plant emergency safety system test method and a nuclear plant emergency safety system test apparatus.

  A new inspection system for nuclear power plants was introduced in 2009 in light of the recent increase in aging nuclear power plants, the prevention of human error and organizational troubles, and the trend of nuclear plant maintenance activities overseas. . This new inspection system replaces the conventional inspection system centered on time-based maintenance, and is a system that incorporates reliability-oriented maintenance based on the deterioration state of nuclear plant equipment at each facility. Inspection of nuclear power plants during operation using such technologies is required.

  Status monitoring in a nuclear power plant can be performed without monitoring the vibration and temperature during operation of dynamic equipment such as motors and pumps installed in the nuclear power plant without performing disassembly and inspection as in the past. It is a technology that makes it possible to grasp the signs of this, and has already been widely introduced mainly in the facilities of regular use.

  On the other hand, the application of the above-described state monitoring has not progressed for an emergency safety system that is an important facility for the safety of a nuclear power plant. An emergency safety system is a system that operates in an emergency such as an accident to stop a nuclear plant safely. The emergency safety system is in a standby state and not operated during normal operation of the nuclear power plant. For this reason, in order to confirm that the emergency safety system operates normally in an emergency, it is stipulated in the safety regulations that periodic tests should be performed on the emergency safety system. The soundness of the system is confirmed.

  For such an emergency safety system, a test apparatus for grasping an abnormality sign during operation of a nuclear power plant has been proposed.

  For example, in the surveillance test apparatus described in Japanese Patent Application Laid-Open No. 2000-242328, the test procedure guide display and test data collection / determination are performed in the surveillance test of emergency response equipment. A configuration is provided in which storage means for storing data and determination results with test date and time information added thereto is added. As a result, for example, the present and past test results can be compared.

  Further, in the state monitoring apparatus described in Japanese Patent Application Laid-Open No. 2008-310659, data changes are made to efficiently collect state monitoring data such as vibration and bearing temperature for emergency equipment that operates only during a surveillance test. Data is stored on the basis of a first threshold for detecting the second threshold, a second threshold for the elapsed time from the change in the driving state, and a third threshold for detecting that the steady state has been reached. A configuration for automatically determining the power period is shown. By automatically determining the data storage period, it is possible to eliminate the burden of a person in charge with skills and knowledge to collect data by looking at the timing during the surveillance test.

  As described above, in order to realize state monitoring for the emergency safety system of the nuclear power plant, it is necessary to collect data from the emergency safety system during the surveillance test. At that time, when considering the efficiency of data collection and reducing the burden on workers, it is effective to use a device that automatically collects the specified data from the emergency safety system during the surveillance test. Found. In addition, it is important to consider the following two items as a device for collecting state monitoring data.

  First, it is easy to add and delete collected data and change conditions. Equipment and monitoring parameters subject to condition monitoring, as well as data collection conditions, should be reviewed sequentially with the advancement of maintenance activities for emergency safety systems.For example, it can be used for pass / fail judgment data for surveillance tests. If fixed, it may not conform to the revised monitoring method.

  Second, data can be collected under preset conditions, and the data collection conditions can be confirmed as necessary. In order to detect signs of anomalies in data collected during state monitoring, it is necessary to compare changes in the data collected periodically. It is important that the state and the temporal relationship with the operation request signal are the same. For that purpose, it is effective to be able to manage data collection conditions for each individual equipment and to record and save these data collection conditions together with the collected data.

  An object of the present invention is to provide an emergency safety system test method for a nuclear power plant and an emergency safety system test apparatus for a nuclear power plant that can accurately monitor the state of an emergency safety system.

A feature of the present invention that achieves the above-described object is that a surveillance test for an emergency safety system of a nuclear power plant is performed based on test guide information including a test of a plurality of procedural steps.
Collect the plant data based on the data collection condition information including the collection start information and the collection completion information regarding the plant data generated by the operation of the equipment in the procedure step in which the equipment included in the emergency safety system operates.
The state of the emergency safety system is to be monitored using the collected plant data.

  Since the plant data is collected based on the information of the data collection conditions including the collection start information and the collection completion information regarding the plant data generated by the operation of the device in the procedure step in which the device included in the emergency safety system operates, The collected plant data can be used to accurately monitor the state of the emergency safety system.

  Preferably, when the data collection condition information for the test of at least one procedural step included in the test guide information of the surveillance test is changed, the collection start information and the collection completion information included in the data collection condition information are corrected. It is desirable to do.

  According to the present invention, it is possible to accurately monitor the state of an emergency safety system of a nuclear power plant.

The plant data input to the input device 11 is input to the test guide control device 12 and the data collection control device 15, respectively.

  Test guide data shown in FIG. 2 is stored in the storage device 13 in advance. The test guide data shown in FIG. 2 is for a certain test ID. The test guide control device 12 reads the test guide data requested by the tester from the input display device 14 from the storage device 13 and outputs it to the input display device 14. The test guide data read from the storage device 13 is displayed on the input display device 14.

  As shown in FIG. 2, the test guide data includes information on each implementation content in the surveillance test, information on operation and confirmation of the emergency safety system equipment for performing the implementation content, and information on pass / fail judgment criteria. The contents of the test in the surveillance test are shown in order for each procedure step (indicated by step No.).

  Information on data collection conditions corresponding to the procedure steps of the surveillance test shown in FIG. 2 is stored in the internal memory 16 of the data collection control device 15. The data collection condition information may be stored in a storage device (second storage device) connected to the data collection control device 15 instead of the internal memory 16. The data collection condition information includes data collection condition information including a data collection step, collection data, a collection start condition, and a collection end condition as shown in FIG. Data collection is not performed at all steps in the surveillance test, but only at the steps specified in the data collection conditions.

  The test guide controller 12 detects a change in the plant state based on the device data and control data included in the input plant data, and automatically determines completion of each procedural step included in the test guide data. Further, the test guide control device 12 determines the time until the equipment operation based on the data for test pass / fail judgment based on the plant data, for example, each plant data obtained in the procedure steps 2 and 4 shown in FIG. Then, data such as the coolant flow rate is created, and the pass / fail is automatically determined in comparison with the pass / fail criterion. Further, the test guide control device 12 outputs the procedure step information of the surveillance test currently being performed to the data collection control device 15.

  Based on the information on the procedural steps output from the test guide control device 12 and input to the data acquisition control device 15 and the information on the data acquisition conditions stored in the internal memory 16, the procedural steps input from the test guide control device 12. When the information coincides with the information of the procedural start procedure step included in the data collection condition information, the data collection control device 15 inputs the plant data input to the input device 11 while performing the test of the procedural step. Collect. When collecting the plant data, the data collection control device 15 judges the collection start and collection completion based on the collection start and collection completion conditions included in the data collection condition information, and automatically collects plant data. To do. The collected plant data is stored in the internal memory 16 and the storage device 21 with a test ID, a data collection ID, and information on the test date and time, respectively.

  For example, when the information of the procedural step output from the test guide control device 12 and input to the data collection control device 15 is step 4 included in the data collection condition information shown in FIG. 3, the data collection control device 15 is a state in which the test of Step 4 of the surveillance test is being performed, and vibration data of the xxx pump is collected, that is, input. The data collection control device 15 starts collecting the vibration data of the xxx pump when the xxx valve is fully opened, the xxx pump is activated, and the xxx flow rate is confirmed, and the vibration data is collected for 60 seconds. Continue sampling. When the data collection time of 60 seconds elapses, the data collection controller 15 stops collecting vibration data of the xxx pump. The collected vibration data is stored in the internal memory 16 and the storage device 21, respectively. When the collected plant data is stored in the internal memory 16 and the storage device 21, the data collection control device 15 gives information on a test ID, a data collection ID, and a test date (data collection date). As shown in FIG. 3, the data collection ID is assigned for each procedure step for collecting data. For example, a data collection ID of “2” is assigned to the vibration data of the xxx pump obtained in the test of Step 4 as shown in FIG.

  The data collection condition information stored in the internal memory 16 is input from the input display device 18 by, for example, a tester before the surveillance test is performed. The procedure for inputting data collection condition information is described below.

  First, a tester inputs a test ID of a surveillance test for which data collection condition information is to be input to the input display device 18. The data collection control device 15 reads the input test ID and causes the input display device 18 to display correction screen information (or additional input screen information) of the data collection conditions currently set for the corresponding test. The examiner then identifies the identification number of the plant data to be collected (for example, “AP0316” and “AP1238” described in the final data column of FIG. 3 and the condition column of the sampling completion column of FIG. 3). “DP0221”, etc.), information on procedure steps for collecting plant data, information on start conditions and end conditions (combining start / end of steps, changes in plant data, and timers), and data collection ID Four pieces of information are input to the input display device 18. The plant data identification number is used to specify the data to be collected. The data collection ID is used to distinguish the data collected in the test. For example, when data with the same identification number (that is, the same physical quantity) is collected under different conditions in the same test, different data collection is performed. It is distinguished by attaching an ID.

  The data collection control device 15 reads the above four information input to the input display device 18, adds the read information (or corrects with the read information), and the latest data collection condition information. Store in the internal memory 16. As described above, in this embodiment, change information (at least one of correction information, additional information, and deletion information) of data collection condition information is input from the input display device 18 and stored in the internal memory 16. You can change the information about the data collection conditions. Changing the data collection condition information means performing at least one of correction of data collection condition information, addition of data collection condition information, and deletion of data collection condition information.

  For example, even when the test contents in the surveillance test procedure step are not changed, the data collection condition information for the test in this procedure step may be changed. In the collection data (xxx pump vibration) with the data collection ID “2” shown in FIG. 3, the data collection condition information is “XXX confirmed flow rate”, but this data collection condition information It is assumed that “confirming the temperature of the fluid discharged from the pump,” which is information on another data collection condition, is added. Corresponding to the addition of “Confirming the temperature of the fluid discharged from the xxx pump”, it is also necessary to add collection start information (collection start conditions) and collection completion information (collection completion conditions).

  Even in such a case, when the tester inputs the four pieces of information described above to the input display device 18, the data collection control device 15 causes the information on the latest data collection conditions changed based on the four pieces of input information. Is stored in the internal memory 16. The data collection control device 15 also has a function as an information change device that changes the collection start information and the collection completion information included in the data collection condition information based on the change information input from the input display device 18.

  After the data collection condition information is updated, the data collection control device 15 collects the plant data output from each control device based on the latest data collection condition information.

  The plant data collected by the data collection control device 15 and stored in the storage device 21 as described above is displayed on the input display device 20 according to the request of the tester in the following procedure. First, a tester inputs a test ID of plant data to be displayed on the input display device 20 to the input display device 20. The input test ID is input to the data management device 19. The data management device 19 reads out the data collection date and time and the candidate information of the data collection ID of the plant data to which the input test ID is assigned from the storage device 21 and causes the input display device 20 to display it.

  Next, the examiner selects the data collection ID and the data collection date / time from the candidate information displayed on the input display device 20, and inputs one or more data collection IDs and data collection dates / times to the input display device 20. To do. The data management device 19 reads out the plant data corresponding to the data collection ID and the data collection date and time selected by the tester and input to the input display device 20 from the storage device 21, and uses the read plant data to display the graph display information. And output to the input display device 20. This graph display information is displayed on the input display device 20. The state of the emergency safety system can be monitored by the displayed graph display information (plant monitoring information). When a sign of abnormality appears in the graph display information, it can be confirmed whether or not abnormality has occurred in the equipment of the emergency safety system.

  According to the present embodiment, since the plant data necessary for monitoring the state of the emergency safety system can be collected during the surveillance test, the plant data necessary for the monitoring can be easily obtained. Can be collected. In order to collect the plant data for monitoring the state of the emergency safety system, it is not necessary to drive the emergency safety system during the periodic inspection of the nuclear power plant except during the surveillance test.

  In the test of each procedural step included in the surveillance test, in the procedural step test in which the devices (for example, valves and pumps) included in the emergency safety system operate, the status of the device that occurs as the device operates is monitored. Therefore, in this embodiment, the state of the emergency safety system can be monitored using the collected plant data. As a result, the state of the emergency safety system can be accurately monitored. be able to.

  In particular, the collection of plant data necessary for monitoring the condition of equipment included in the emergency safety system is the operation of the equipment at the corresponding procedural step in the surveillance test (the procedural step in which the equipment included in the emergency safety system operates). Data collection conditions including information on the start of collection (including information on the conditions for starting the collection of plant data obtained in the procedure step) and information on completion of collection (including information on the conditions for completion of collection of the plant data) Therefore, in the test of the procedural steps in which the equipment (for example, valves and pumps) included in the emergency safety system operates, the same surveillance test can be used under the same conditions to monitor the condition of the equipment. Necessary plant data can be collected. For this reason, the state of the emergency safety system can be accurately monitored by monitoring the state of the emergency safety system using the plant data thus collected.

  At a nuclear power plant, the emergency safety system is modified, the detector for detecting plant data used to control the emergency safety system, the detector installation position, the process data collection time, etc. are changed. There is also. When such a modification or change is made, the test content of the surveillance test is changed, and the test content in at least one procedural step included in the surveillance test is changed. Further, although the test contents in the procedural steps are not changed, the data collection condition information may be changed as described above. In addition, with the improvement of the state monitoring technique, data to be collected and its conditions are usually reviewed sequentially. At the same time, the data collection condition information must be changed. In the present embodiment, as described above, information for changing the data collection condition information can be input from the input display device 18, and the data collection condition stored in the internal memory 16 based on the input change information. Information can be modified. For this reason, when the contents of the surveillance test are changed based on the modification or change as described above, the information on the data collection conditions can be easily corrected along with the change of the contents of the surveillance test. . In addition, if the data collection condition information is changed without changing the surveillance test, the collection start information and the collection completion information included in the data collection condition information can be easily It can be corrected. As a result, this embodiment can accurately monitor the state of the emergency safety system.

  In particular, in this embodiment, the collection of plant data necessary for monitoring the condition of the equipment included in the emergency safety system during the surveillance test is performed as described above, and the equipment included in the emergency safety system during the surveillance test is activated. In the procedural step, including information on the start of collection related to plant data (including information on the conditions for starting the collection of plant data obtained in the procedural step) and information on completion of collection (including information on the conditions for completing the collection of plant data) This is performed based on data collection condition information. For this reason, when the content of the surveillance test is changed as described above, it corresponds to the procedure step in which the equipment included in the emergency safety system operates among the procedure steps whose content has been changed in the surveillance test. It is sufficient to correct the data collection condition information. In addition, if the data collection condition information is changed without changing the surveillance test, the collection start information and the collection completion information included in the data collection condition information should be modified along with this change. It ’s fine. For this reason, it is included in the data collection condition information stored in the internal memory 16 in accordance with a change in the content of the surveillance test and a change in the data collection condition information when the content of the surveillance test is not changed. Correction of collection start information and collection completion information becomes easy. By correcting the data collection condition information stored in the internal memory 16 in accordance with the procedural steps in which the equipment included in the emergency safety system operates, the state of the emergency safety system is accurately monitored. Can be realized. Also, when modifying the data collection condition information including the collection start information and the collection completion information in accordance with the change of the surveillance test execution contents or the change of the data collection condition information when the surveillance test implementation contents are not changed Is a procedural step subject to the change, and changes information for changing the data collection conditions corresponding to the procedural step in which the equipment included in the emergency safety system operates, changes the emergency safety system test device 10 emergency safety system status monitoring devices may be input.
