2 is a flowchart showing a nuclear power plant fire emergency response method according to an embodiment of the present invention, (a) confirming a fire zone of the nuclear power plant, (b) selecting one of the fire zones provided in the nuclear power plant, ( c) tentatively determining a fire suppression route and an evacuation route through the drawings of the selected fire zone, (d) inspecting the tentatively determined fire suppression route and evacuation route; and (e) determining a fire suppression and evacuation route in the selected fire zone, and (f) checking whether a fire zone in an undetermined state exists.

In the nuclear power plant fire emergency response method of the present invention, step (a) is a step of confirming the fire prevention area of the nuclear power plant.

The nuclear power plant fire emergency response method of the present invention provides safe and rapid access to or evacuation of workers, workers, operators and firefighters in response to emergency situations such as fire by fire zone when analyzing the fire risk of a nuclear power plant. It is a method of preparing a passageway to prepare fire suppression and evacuation measures.

Since a fire in a nuclear power plant can occur in any fire zone, step (a) is the step to verify information on all fire zones in the nuclear power plant.

Next, step (b) is a step of selecting one of the fire protection zones provided in the nuclear power plant.

It is necessary to prepare an emergency response plan for each fire zone for a virtual fire in the nuclear power plant emergency response method.

In this step, as the first step to prepare an emergency response plan for all fire zones in the nuclear power plant, one fire zone is selected.

Next, step (c) is a step of tentatively determining a fire suppression route and an evacuation route through the drawings of the selected fire zone.

In this stage, the fire emergency response plan for the selected fire zone is tentatively decided, which is based on the drawings of the selected fire zone.

The drawings of the fire area show the various equipment installed inside the fire area and the many cables connected thereto and emergency exits such as one or more entrances.

In the event of a fire in the relevant fire zone, it is necessary to determine the fire suppression route to quickly and safely access the fire location, and determine the fire evacuation route that can minimize human casualties by evacuating quickly from the fire location. it is necessary to do

The fire suppression and evacuation route tentatively determined in this step is determined according to the equipment and emergency exits shown in the drawings of the relevant fire zone.

Next, step (d) is a step of inspecting the tentatively determined fire suppression and evacuation route.

In this step, it is a step of checking whether editing of the fire suppression and evacuation route tentatively determined in step (c) is necessary.

Each fire zone of a nuclear power plant may have facilities and emergency exits identical to the designed drawings or drawings, but may be used inconsistent with the drawings in hand due to facility changes or location changes of emergency exits.

In addition, there are cases in which items are piled up among emergency exits and cannot be actually opened or closed.

As such, this stage is a stage of inspection through verification while comparing the inspection results of each fire zone of the nuclear power plant with the drawings in hand.

At this stage, it will be possible to propose a change in the location of emergency exits, etc. in order to determine a safer and more efficient fire suppression and evacuation route.

Next, step (e) is a step of determining the fire suppression and evacuation route of the selected fire zone.

This step is a step to finally determine the fire suppression and evacuation route for the selected fire zone after inspecting the tentative route determined in step (d). Save fire extinguishing and evacuation routes as appropriate.

Finally, step (f) is a step to check whether a fire zone with an undetermined route exists.

If there is a fire zone with an undetermined route, steps (a) to (e) are performed and the process of determining the fire suppression and evacuation route is repeated. will be able to establish

The fire emergency response method at nuclear power plants as described above requires that emergency response methods be prepared for all fire zones. There is a problem that not only takes a lot of time, but also many errors may occur.

In order to solve this problem, it may be more preferable to implement the nuclear power plant fire emergency response method as a program executed on a computer. It is obvious that the program may be stored in a recording medium.

The program of the nuclear power plant fire emergency response method is executed on a computer, which as shown in FIG. 3 (s1) checking the existence of nuclear power information, (s2) selecting a nuclear power plant, (s3) checking the existence of a drawing, ( s4) drawing selection step, (s5) setting information of the corresponding drawing in the selected drawing; (s6) provisional determination of fire suppression and evacuation routes; (s7) provisionally determined path inspection step; and (s8) creating a fire suppression and evacuation plan.

The step (s1) of determining whether nuclear power plant information exists is a step of confirming whether information about a nuclear power plant to determine a fire emergency response method exists.

This is a step that makes it possible to apply the fire emergency response method to a number of nuclear power plants other than a specific nuclear power plant in the program.

The DB module may be provided in the computer in which the program is executed, or may be a DB module stored in an external server.

Since information on the nuclear power plant to which the fire emergency response method is applied can still be additionally stored in the DB module, it becomes possible to apply the fire emergency response method of the nuclear power plant more efficiently.

In the present invention, the information of nuclear power plant means information shown in the drawings for each fire zone of the nuclear power plant, and it is preferable that the fire extinguishing facilities, compartments, cable connection structures, emergency exits and legends of each fire zone are shown in the drawings as described above. .

Next, step (s2) is a step of selecting a nuclear power plant.

As shown in FIG. 3, when information on a nuclear power plant to which the fire emergency response method is applied to the DB module connected to the program already exists in the computer or the DB module, it is possible to select the nuclear power plant by calling it.

If there is no information on the nuclear power plant to which the fire emergency response method is to be applied, as shown in FIG. 3 , the step of generating information on the nuclear power plant should be performed first.

The step of generating the information on the nuclear power plant includes the step of digitizing the information on the nuclear power plant, and if there is a missing fire zone drawing, it includes the step of creating and digitizing it.

The information on the generated nuclear power plant needs to be stored in the computer where the program is executed, and it will also be possible to store it in the DB module.

Next, step (s3) is a step of confirming the existence of the drawing.

This step is the step of selecting a fire zone and checking whether an electronic drawing of the selected fire zone exists in the computer.

Next, step (s4) is a drawing selection step.

This is the step of selecting the drawing of the selected fire zone, and if the drawing exists in the computer, you can select it.

At this time, when the corresponding drawing does not exist in the computer or when additional drawings are registered, the drawing file is called from the DB module or the like.

Next, step (s5) is a step of setting information of the corresponding drawing in the selected drawing.

In this step, the layer information existing in the selected drawing is called, the fire zone is recognized through the layer information, the emergency exit is input, the object including the path is set, and a legend is set. In addition, in order to clearly identify the route, the thickness of the line in the drawing may be additionally set, and it will be possible to additionally set the direction of the fire suppression and evacuation route.

Each of the settings in this step can be configured to be conveniently set by programming a pop-up window to appear as shown in the screen example of the program executing the nuclear power plant emergency response method according to the present invention in FIG. 4 .

Next, step (s6) is a provisional determination of fire suppression and evacuation routes.

This step is a step of creating a fire suppression and evacuation route by using the layer information of the corresponding drawing set in the step (s5) and the set information.

The corresponding path generation can be manually or automatically generated, and automatic path generation can be implemented by applying a path finding algorithm.

The fire suppression route can be implemented to create a fire suppression route by selecting the current location and a fire point, and the fire evacuation route can be implemented to create an evacuation route to the outside when the current location is selected.

Pathfinding Algorithms for Automatic Path Creation One of many known algorithms may be used, which when creating a fire suppression path is configured to create an optimal fire suppression path that is quickly accessible from the passageway between the current location and the point of fire. can do.

In this case, the point of occurrence of the fire may be the emergency exit, which is the entrance to the relevant fire zone where the fire occurred. In addition, the emergency exit of the fire prevention area can be created as the destination point of the fire suppression route, the location currently prepared by firefighters, etc. can be created as the starting point, and a fire extinguisher or hydrant provided in the fire area in the route finding algorithm It may be possible to create an automatic route by additionally considering fire extinguishing equipment, such as.

On the other hand, it is possible to manually create a route. Even in this case, it is preferable to form the passage in consideration of the passage between the current point and the emergency exit of the virtual fire prevention area, and it will be possible to form the route via a fire extinguisher or a fire hydrant. .

Next, step (s7) is a provisionally determined path inspection step.

As seen in the above step of the fire emergency response method at the nuclear power plant, if the drawing of the fire zone does not match the actual structure of the nuclear power plant or if the actual opening and closing is impossible due to piled up items in the emergency exit, there is no need to edit or modify the route. there is.

In addition, if the location of the emergency exit is changed and the fire suppression and evacuation route can be significantly shortened, it may be necessary to reset the route by changing the location of the emergency exit.

As such, when editing or correction of a path is required, the path is reset after correcting it in the drawing.

Next, step (s8) is a step to create a fire suppression and evacuation plan.

The fire suppression and evacuation plan refers to a drawing showing the fire suppression and evacuation route corresponding to a virtual fire in each fire zone in the fire emergency response method of a nuclear power plant.

This step is a step of storing a drawing in which the finally determined nuclear power plant fire suppression and evacuation route is set after inspecting the route tentatively determined in step (s7). The stored fire suppression and evacuation plans for each fire zone can also be stored in the DB module to be effectively applied to nuclear power plant fire emergency response.

As seen above, by programming the nuclear power plant emergency response method, the reliability of the nuclear power plant fire emergency response can be improved by minimizing errors and providing more efficient evacuation and access routes for the safety of workers, workers, operators and firefighters. there is.

The present invention is not limited to the above-described embodiments, and the scope of application is varied, and anyone with ordinary knowledge in the field to which the present invention pertains without departing from the gist of the present invention as claimed in the claims It goes without saying that various modifications are possible.
