Description

Technical field

[1] The present invention relates to a training method for determining the scope of a radiation emergency based on a simulated accident and, in particular, to a training method for determining the scope of a radiation emergency based on a simulated accident, according to which training can be carried out similarly to a real radiation accident, so that simulated accident scenario, collect location-based simulated real-time detection data in real time according to However, with the developed scenario, they also change the current state of radiation leakage at the central control room.

[2] Background

[3] Attention to accidents related to the leakage of radioactive substances increased after the accident related to the leakage of radioactive substances from the Fukushima reactor in March 2011. In this regard, the South Korean government adopted the Law on the Protection and Prevention of Radiation Accidents for Nuclear Installations, etc., and also expanded and changed the radiation emergency planning zone from the existing 8 ~ 10 km to 20 ~ 30 km.

[4] “Radiation emergency” (hereinafter simply referred to as “accident”) refers to an emergency in which there is a leak of radioactivity (radioactive substance) to the outside, and it should be understood that leakage of radioactivity (radioactive substance) to the outside can occur as a result of several incidents and / or failures that may occur in a nuclear installation. “Radiation emergency planning zone” refers to the standard zone, which must be carefully prepared in advance for the implementation of measures to protect the public, for example, prepare protective medicines, provide a medical care station, evacuation and relocation, in preparation for a possible emergency leak of radioactivity from nuclear installation. However, in a radiation emergency, the radiation leak may not be limited to the radiation emergency planning area. Accordingly, in the present invention, the term "accident zone" refers to the place where radiation exposure occurs or there is a risk of radiation exposure due to an accident, war, terrorist act, natural disaster, deliberate action. In other words, the accident zone is all zones or areas in which there is a possibility of potential damage by radioactive radiation, in addition to the radiation emergency planning zone.

[5] In the event of a radiation emergency, the primary task that must be completed for a quick initial response, as well as for the preparation and implementation of measures to protect the public, is to verify information on the current state of radiation propagation and change the nature of radiation leakage in the zone, that is . radiation propagation information. This is because the level of countermeasures and the scale of the accident can be determined based on real-time radiation propagation information.

[6] To date, to provide data on the distribution of radiation levels in the accident zone, so that in the event of an accident, information on the distribution of radiation can be verified, provide a monitoring system that includes many radiation monitoring systems, a communication network and a control server, as well as a monitoring network .

[7] The radiation monitoring system (RMS) is a device that is installed in several places in the accident zone before / after the accident or is moved to the accident zone and which measures the level of radiation at every location on the ground, in the sea and in the air. The radiation monitoring system, as a rule, has the function of measuring the level of radiation, the GPS function and the communication function in real time (such functions can be physically implemented in other devices). The monitoring system of a fixed type is fixed and located in the main place in which it is necessary to control the level of radiation. The rolling type monitoring system includes a type in which, in the event of a radiation emergency, the system is moved and placed at a predetermined main point, a type in which the system is installed on a vehicle or vessel and moved along the road according to a predetermined route or by sea, type, in which the system is mounted on a helicopter or aircraft and moved, and the type in which the system is carried by an interested person who moves it along a given or special route. As described above, the process of measuring the level of radiation in the area of the accident zone is referred to as the “detection process”, the route along which various monitoring systems move is referred to as the “detection path”, and the radiation level information measured during the detection process is referred to as “data detection. "

[8] A management server is a server managed by an institution (a state or local government institution or a subordinate institution that is part of several institutes that can be provided by law. For example, a focal point for radiation monitoring, hereinafter referred to as the “administrative institution”) , which manages and administers the radiation emergency monitoring system.

[9] In accordance with such a monitoring system, in normal times, a fixed-type monitoring system regularly measures the level of radiation at a specific location within the zone and transmits data on the measured level of radiation to the control server. In the event of a radiation emergency, various mobile monitoring systems work on the detection route, measure radiation levels in several places within the accident zone in real time, and transfer the values of the measured radiation levels to the control server via the network. The institute that administers the management server (the management server may be a plurality of physically separated devices) obtains information on the propagation of radiation in the accident zone by combining radiation levels based on real-time location. For example, an institute, such as the central command headquarters in a radiation emergency, determines the level of countermeasures and the scale of the accident based on information about the spread of radiation.

[10] The operation of a monitoring system to obtain such radiation propagation information typically includes:

Stage 1 of obtaining the results of measuring the level of radiation in the area of the accident zone,

Stage 2 of checking the state of the collection of radiation levels based on the real-time location received from the respective monitoring systems, and applying information on the distribution of radiation on the map by combining the collected radiation levels and

Stage 3 response to determine the most effective warning of the spread of the accident and the implementation of measures to protect the population on the basis of information about the spread of radiation in real time.

[11] At the same time, as in the training of operating another basic emergency planning system, the monitoring system for obtaining information on the propagation of radiation in case of emergency should periodically or aperiodically conduct simulated training even in normal times. However, in a conventional monitoring system, training can be carried out to the extent that the monitoring systems pass along the planned detection route according to the emergency plan from the moment a simulated radiation emergency occurs, but such training does not make sense in terms of efficiency and reality, since the level of radiation in the area of the simulated accident is the same as during normal times. In addition, training at the state verification stage and the response stage, i.e. at the last stages, is inevitably shared without coordination with the stage of obtaining measurement results, i.e. with the preceding step, since the location-based real-time radiation levels at the stage of obtaining measurement results are normal values. In other words, the effectiveness of training is low, since the simulated training in a conventional monitoring system occurs inconsistently.

[12] In this case, the traditional technology is a technology for checking and controlling contamination of radioactivity as a result of an emergency by measuring the radiation dose in a certain area by wire / wireless in real time. Known are the technologies for connecting the estimated results to a geographic information system (GIS) and defining response measures and / or countermeasures, for example, countermeasures to protect the public in the field of contamination with a radioactive substance (publication of Korean patent application No. 10-2003-0086646, publication of Korean patent application No. 10- 2008-0007821, Korean Patent Application Publication No. 10-2014-0120979).

[13] However, traditional technologies do not provide a systematic idea of how the training of various radiation pollution monitoring systems will be carried out in terms of approaching real conditions and how reliable the monitoring system will be.

[14] Technical challenge

[15] An object of the present invention is to provide a training method for determining the area of a radiation emergency based on a simulated accident, the operation of a radiation emergency monitoring system can be trained similarly to a real radiation emergency.

[16] Furthermore, an object of the present invention is to provide a method for evaluating the results obtained when training in a radiation emergency based on a simulated accident.

[21] Furthermore, in accordance with the present invention, the ability to respond to a radiation emergency that is difficult to predict can be improved since training can be performed in accordance with various scenarios.

[22] In addition, in accordance with the present invention, training, in approximate real conditions, in checking a radiation emergency and determining a response plan can be performed using the collected information in addition to the usual collection of real measurement information.

[31] The present invention is further described in detail with reference to the accompanying drawings. However, the accompanying drawings are only illustrative and are intended to facilitate understanding of the content and range of the technological essence of the present invention, and the technological range of the present invention is not limited to these drawings. Various modifications and variations of the present invention within the range of the technological essence of the present invention will be apparent to those skilled in the art based on examples.

[32] According to the above description, the present invention relates to a method for training in determining the scope of a radiation emergency based on a simulated accident using: a plurality of radiation monitoring systems to provide data on the distribution of radiation levels so that when a radiation emergency occurs, information about radiation propagation from the accident zone, a monitoring network containing a management server that wirelessly communicates with the system s control, and the learning server performing wireless communication with the control system, and includes a process of determining a scenario producing process of simulated radiation levels and simulated radiation gathering process information dissemination. In FIG. 1 generally shows the objects involved in the training method according to the present invention, and the relationship between these objects, and in FIG. 2 generally shows a diagram depicting a relationship in the transmission of information between objects participating in a training method according to the present invention.

[33] In the present invention, a "radiation monitoring system" or "monitoring system" is a device that typically has a radiation level measurement function, a GPS function and a real-time communication function and which are located in several places in the accident zone before occurrence emergency / after an emergency or move along the planned route (detection route) in the accident zone, which measures the level of radiation based on the location in real time on the ground, and the sea and in the air, and transmits the measured radiation level to the management server. The term “planned” means “defined in an action plan”.

[34] In the present invention, a “management server” is a server managed by an administrative institute that manages a radiation emergency monitoring system and is configured to receive radiation level data based on location in real time from a plurality of monitoring systems and obtain propagation information radiation in the zone by combining received radiation level data.

[35] In the present invention, a “training server” is a server operating in conjunction with a monitoring network only in the case of training and configured to determine a radiation propagation scenario and transmit a radiation propagation scenario to monitoring systems.

[36] In the present invention, each of the monitoring systems provides only part of the information about the level of radiation or transmits or receives only part of the information about the level of radiation at a certain point in time. Accordingly, information about the level of radiation obtained by measuring the level of radiation or transmitted or received by one monitoring system at a certain point in time is referred to as a “data element”, i.e. in the singular form, and information, i.e. the plurality of parts of data elements is referred to as “data”.

[37] In a radiation accident, odorless and colorless radiation can spread over long distances. In this case, although in practice a large number of control systems are installed, it is impossible to completely cover a vast area in real time and to measure radiation levels. Accordingly, the reality is that when moving in the accident zone, the pollution level must be measured using fixed-type monitoring systems or using fixed-type and movable-type monitoring systems. In the present invention, “real time” can be essentially real time, taking into account such reality, but can mean time within a certain time range. In the latter case, for example, real-time data can be all data on the level of radiation in the accident zone, which are measured over 10 minutes.

[38] In the present invention, the scenario setting process is a process of receiving virtual data of a radiation level for each agreed location in real time within a dedicated training zone using the training server, in which the simulated radiation level in each planned time training zone for the dedicated training zone set by the training administrator, and saving the received virtual data of the radiation level. The script definition process is the process of obtaining the script, i.e. set data [location - time - simulated radiation level] containing the simulated value of the radiation level at each moment of the planned training time for each location of the selected training zone, and saving the script.

[39] When a scenario is established, the distribution of the distribution zone for each level of contamination with radioactive substances is adjusted, the level of the radiation accident (= given data element) for each location of the training zone - each time zone, etc.

[40] This can be visually presented in such a way that the scenario takes the form of information about the distribution of radiation levels at a certain point in time, which is shown on the map of the target training zone. In FIG. 3 shows an example in which the scenario is depicted on a map in the form of contour-shaped graphs. In FIG. 3, the radiation level rises from the green to red, i.e. increased levels of radiation pollution. For example, the green region may correspond to a radiation level of 100 nSv (nanosievert) / h or less, and the red region may correspond to 1 mSv / h or higher. In FIG. Figure 3 shows radiation level information for each location in the accident zone at a particular point in time. A scenario can be defined for a fixed specific point in time, but in such a way that there is an exact change in information about the distribution of radiation levels, taking into account changes in a radiation emergency, changes in wind speed or wind direction, etc. For example, more realistic training is possible with a different scenario setting at intervals of 30 minutes from the start of the training. However, although they use one scenario or many precisely tuned scenarios, the basic way of learning remains the same. Accordingly, the present invention describes an example in which one scenario is set.

[41] In the present invention, the process of obtaining a simulated level of radiation is the process of transmitting a virtual data element in accordance with the scenario to each of the control systems, and any of the following two methods can be selected as the process of obtaining a simulated level of radiation.

[42] 1 The first method (“pre-configuration method”) is intended for the learning server to perform configuration by transmitting information from the installed script to each of the control systems before training begins. This setting can be done offline. If this method is selected, the mobile-type monitoring system extracts information (virtual data element) about the radiation level in the scenario information corresponding to the location in real time (current location and time), moving along the detection route in accordance with the action plan. In addition, the monitoring system of a fixed type or settable type retrieves the virtual data element in real time.

[43] An example of planned detection routes for all monitoring systems is shown in FIG. 4. In FIG. 4, the route, which has the shape of a zigzag line, directed up and down, corresponds to the route of detection of the control system installed on the aircraft.

[44] 2 The second method described below (“real-time method”) can be applied if the control system does not have the function of storing and managing scenario information.

[45] First, when training begins, in the case of moving-type systems, many radiation monitoring systems transmit real-time location data (current location and time) to the training server directly or through the control server, moving along the detection routes in accordance with a predefined action plan. In the case of a monitoring system of a fixed type or an established type, a single transmission of location information is sufficient since the monitoring system is fixed. Then, the training server, which received the real-time location data of the corresponding control systems, transmits a virtual data element installed in the script to each of the control systems corresponding to a specific location in real time (i.e., the current location and time) established in the scenario, i.e. to each of the monitoring systems in the location according to the scenario at some point in time in the scenario.

[46] When performing the process of obtaining a simulated radiation level, the location-based virtual data element in the script is preferably displayed in each of the real-time learning control systems. In this case, in order to distinguish between a location-based virtual data element and an actual measurement data element (= information of actually measured radiation level), a certain marker may be associated with the virtual data element. The relevant person related to this area provides the appropriate countermeasure for the area based on the virtual data item marked in the control system.

[47] In the present invention, a process for collecting information on a simulated radiation propagation is a process for collecting, using a control server, a virtual data element from each of the monitoring systems in real time and receiving information for a simulated radiation propagation by combining virtual data. The flow of this process is carried out similarly to the process of obtaining information about the actual propagation of radiation and it can also include two stages.

[48] First, each of the plurality of monitoring systems transmits a location-based virtual real-time radiation level data element received from the training server to the control server. In this case, the virtual data element is a virtual data element obtained by the monitoring system at the current location in accordance with the "preset method", and is a virtual data element received from the learning server in real time in accordance with the "real time method" . When the virtual data item is transmitted to the management server, the actual measurement data item may also be transmitted. In order to distinguish between a virtual data element and an actual dimension data element, a specific marker may be associated with the virtual data element. In addition, to approximate the real conditions, the actual measurement data element can be included (for example, added or subtracted) in the virtual data element received from the training server and transmitted to the control server.

[49] Then, the management server collects the virtual radiation level data at appropriate locations in real time received from a plurality of monitoring systems, stores the collected virtual radiation level data and combines them using one of the methods, for example, matching the detection route with a simulated radiation level, measured along the detection route. In FIG. 5 illustrates simulated radiation levels measured on the detection route during training in accordance with a scenario, for example, in FIG. 3, and detection routes, for example, in FIG. 4. In addition, the management server receives information about the simulated propagation of radiation in the accident zone in real time by a comprehensive analysis of the results of such detection. In this case, preferably the information of the simulated propagation of radiation takes the form of information about the distribution of radiation levels at a specific point in time, which is shown on the map of the target training area. In FIG. 6 shows an example in which information of a simulated radiation propagation obtained by analyzing and combining information obtained in FIG. 5 is displayed on the map in the form of contour-shaped graphs.

[50] In this case, the wireless network in an emergency, such as a radiation emergency, can be heavily loaded. Accordingly, in the present invention, each piece of information (data item / data) is preferably transmitted in a corresponding defined cycle.

[51] FIG. 2 schematically shows the elements involved in a method of teaching the determination of a radiation emergency area based on a simulated accident according to the present invention, and the transmission of information between these elements, the control server and the training server being shown as having a type that involves their separation and communication between them. However, in the present invention, the management server and the training server can be installed on the same physical server, since they are functional concepts.

[52] However, the present invention is not limited only to a training method for determining the area of a radiation emergency based on a simulated accident, but also includes an assessment method that allows learning results to be evaluated in accordance with the training method.

[53] In other words, after the aforementioned scenario setting process, a process for obtaining a simulated radiation level, and a process for collecting information on a simulated radiation propagation, the following learning assessment process can be added. In the learning assessment process, learning outcomes are evaluated by comparing virtual radiation level data for real-time locations (i.e., set “location-time-simulated radiation level” data in the training area) in a script in process (A) stored on the server training, with virtual radiation level data (i.e., detection data) for real-time locations obtained and measured in process (C) and integrated by the management server.

[54] For example, if we assume that the training is based on a simulated radiation propagation scenario, for example, in FIG. 3, and the results obtained as a result of training are obtaining information on the propagation of radiation, for example, the information presented in FIG. 3 and 5, how accurately the training was conducted can be assessed by determining the similarity between the results in FIG. 3 and 5 and the results of FIG. 3.

[55] The workflow of the learning method is also described in connection with the relevant person.

[56] 1) The training administrator develops the information of the accident scenario in which the zone of the simulated accident for each accident and the level of radiation pollution (radiation level) for each zone in the simulated area of the accident is established, before training and stores the developed information of the accident scenario on the training server .

[57] 2) When emergency response control systems operate during training, accident scenario information is transmitted to the monitoring systems by communicating with the training server, therefore, the monitoring systems are automatically configured (can be configured offline).

[58] 3) Each of the monitoring systems automatically calculates a virtual data item in the accident scenario based on the location information of the monitoring system (collects fixed installation location data or location information using GPS) whenever it performs an actual measurement. In this case, the sum of the actual measurement data element and the virtual data element can be a virtual data element (= measured value for training). Both the data element of the actual measurement that was actually taken, and the virtual data element for training can be displayed in the control system.

[59] 4) Location information, time information, and a virtual data element of each monitoring system are automatically transmitted to a management server located at a remote central command headquarters.

[60] 5) The person responsible for the response in the accident area controls the virtual data element of the control system and ensures that the response tasks in the area are performed in the event of an emergency.

[61] 6) The management server of the remote central control headquarters integrates and monitors the virtual data elements collected in the field in real time and issues a decision regarding measures to protect the population through training in the implementation of a centralized emergency response and analysis task data.

[62] 7) Coordination training in carrying out the response task between the remote central command headquarters and the person responsible for the emergency response is a real-time modeled accident information exchange and intent exchange.

[63] 8) After training, the training administrator evaluates the training by performing a response procedure in the event of an accident, time spent, accident scenario and compares the results of the training analysis.

[64] According to the training method described above, determining the area of a radiation emergency based on a simulated accident according to the present invention to achieve effective emergency response training in the accident area and in the control center under conditions similar to a real radiation emergency, training in responding to a radiation emergency in the accident area and at the central control point, they can carry out / evaluate using equipment for taking countermeasures in real emergency situation and real working environment as applied to the scenario of a simulated accident with a leak of a radioactive substance in accordance with the method of software and hardware modeling.

[65] In addition, according to the present invention, the ability to respond to a radiation emergency can be improved since training in obtaining information on the propagation of radiation in the intended accident zone is performed in an environment similar to a real environment, in accordance with various emergency scenarios when performing training in actions in a radiation emergency.
