Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rough shielding required dimension evaluation support system for evaluating and determining rough shielding required dimensions of a shielding wall thickness and a ceiling thickness in an early stage of designing a nuclear facility.

[0002]

2. Description of the Related Art In the initial stage of the design of a nuclear facility, it is necessary to evaluate the required thickness on the shield, which is the basis of the amount of building for dynamic analysis, at the stage when the rough layout is decided. Conventionally, in order to determine the required shielding dimension, a design engineer looks at materials such as shielding wall thicknesses and ceiling thicknesses of a plurality of existing nuclear facilities to search for adjacent relationships including the upper and lower relationships of the same or similar equipment rooms.

Further, a method is adopted in which the shielding wall thickness and the ceiling thickness between the equipment rooms are successively evaluated and determined by correcting the difference in radioactivity concentration in the coolant between the existing nuclear facility and the new nuclear facility. It was Then, a method is adopted in which the determined required shielding dimension is manually input to a layout drawing by CAD (computer-aided design) to create a required shielding dimension diagram.

[0004]

In the conventional method for evaluating the required shielding dimension and creating the required shielding dimension drawing, a large amount of drawings are referred to for a large amount of shielding wall and ceiling thickness, and the radioactivity concentration in the coolant is also increased. Since it is necessary to correct the design conditions such as the difference between the two, there is a problem that even an expert in radiation shielding design needs a lot of work time for the evaluation.

Further, the determined required shielding dimension may differ depending on the judgment of the evaluated design engineer.
In addition, once the required shielding dimensions have been evaluated / determined, if the design conditions of the new nuclear facility are changed, it is necessary to re-evaluate by reviewing a large amount of data.

The present invention has been made to solve the above problems, and automatically and in a short time by using the design data of an existing nuclear facility and the design conditions of a new nuclear facility stored in a storage device. It is an object of the present invention to provide an evaluation support system for a rough shielding required dimension, which enables engineers to evaluate the rough shielding required dimension without quality variations and to immediately display the evaluation result on the screen together with the equipment room layout.

[0007]

[Means for Solving the Problems] The present invention is based on the criteria for setting the radioactivity concentration / radiation level classification in coolant of an existing nuclear facility.
A storage device that stores the equipment room name, radiation level classification data for each equipment room, layout data for adjacent equipment rooms on the horizontal and ceiling floors, design data composed of shielding wall thickness and ceiling thickness, and coolant for new nuclear facilities A storage device that stores design conditions consisting of radioactivity concentration / radiation level classification setting criteria, equipment room name, radiation level classification data for each equipment room, position coordinate data for each equipment room, and the floor plan of the new nuclear facility It has a storage device for storing the figure data, and further, from the position coordinate data of each equipment room of the new nuclear facility by the arithmetic device, the adjacent equipment room layout data on the lateral and ceiling floors of the new nuclear facility-Wall and ceiling position coordinates Automatically generated and saved, and then the design data of the existing nuclear facility and the design conditions of the new nuclear facility and the side and ceiling floors of the new nuclear facility. While comparing the contact equipment room arrangement data to evaluate the general shielding wall thickness and ceiling thickness of new nuclear facilities automatically records the schematic shielding required dimensions evaluation results and evaluation course. Furthermore, the display device is characterized in that the building plan view data and the rough shielding wall thickness or ceiling thickness are combined and displayed on the screen, and the display screen can be copied onto paper, OHP, or the like.

[0008]

According to the present invention having the above-mentioned configuration, the equipment room name of the existing nuclear facility, the name of the adjacent equipment room on the side and ceiling floor of each equipment room, the shielding wall thickness between the adjacent equipment room, and the ceiling thickness data are stored. It is stored in the device. Also for new nuclear facilities, design conditions consisting of radioactive concentration in coolant, radiation level classification setting standard, equipment room name, radiation level classification data of each equipment room, and position coordinate data of each equipment room are stored in the storage device. Remembered

First of all, for a new nuclear facility, the arithmetic unit shows from the position coordinate data of each equipment room the adjacent equipment room layout data on the horizontal and ceiling floors, that is, which equipment room exists around each equipment room and on the upper floor. Generate and store data and wall and ceiling position coordinates between them and their adjacent equipment rooms.

FIG. 2 is a flow chart showing an example of a procedure for generating lateral adjacent equipment room layout data and wall position coordinates from the equipment room position coordinate data. Take out one line that composes the area of interest (equipment room),
Search for another area (equipment room) that has a line parallel to the line.

Whether the line of the own region and the line of the other region are less than a certain interval (for example, 2 m), are located at the position forming the wall (that is, whether parallel lines overlap each other), or both lines Check for another area (equipment room) between the minutes. If these conditions are satisfied, the area is recognized and saved as an adjacent area, and the position coordinates are saved as a range surrounded by both line segments as a wall.

FIG. 3 is a flow chart showing an example of a procedure for generating the adjacent equipment room layout data on the upper floor and the position coordinates of the ceiling from the position coordinate data of each equipment room and the position coordinate data of each equipment room on the upper floor. is there. Own area of interest (equipment room)
On the other hand, all the other areas (equipment rooms) having a line intersecting the line forming the upper region and the region forming the own region including the apexes of the line forming the region are searched and stored.

Next, for those areas, overlapping areas are deleted, and the remaining area and the area surrounded by the remaining area are recognized and saved as adjacent areas on the upper floor, and at the same time as the own area and the upper area. The position coordinates are saved with the ceiling as a range where adjacent areas on the floor overlap.

Next, the computing device determines the approximate shielding wall thickness / ceiling thickness between the equipment room of interest in the new nuclear facility and its adjacent equipment room. FIG. 4 is an example of a flowchart showing the procedure.

First, pay attention to an area (equipment room) where a new nuclear facility is located, and let this area be A, and focus on one wall or ceiling of the area. An area (equipment room) adjacent to the wall or ceiling is searched from the equipment arrangement data obtained by the arithmetic processing, and the adjacent area is designated as B. All the combinations of the adjacency relations of the areas A and B are searched from the design data of the existing nuclear facility.

When a plurality of combinations are found, the one having the closest design condition is adopted. If the same combination is not found in the above search, for example, all combinations of radiation level divisions for areas A and B are searched from the design data of existing nuclear facilities, and the one with the closest design condition is adopted, and the next best is selected. Use as an evaluation value.

As described above, by changing the search condition, the combination of the same or similar areas for the areas A and B can be searched from the data of the existing nuclear facility. Therefore, the thickness of the wall or ceiling between the two regions of the existing nuclear facility found is taken out, and the thickness is set as the thickness of the wall or ceiling between the two regions A and B of the new nuclear facility.

If the evaluation value cannot be obtained even if the condition is changed, the thickness may be input from the outside and set. In addition, the radioactive material concentration / radiation level classification standard in the coolant of the existing nuclear facilities and the design conditions of the new nuclear facility corresponding to them are also stored in the storage device. It can be performed.

In this way, it becomes possible to automatically determine the required rough shielding dimensions such as the rough shielding wall thickness and the ceiling thickness, which conventionally required a lot of working time, in a short time. Further, the evaluation of the rough shielding required dimension by the arithmetic unit is performed under the determined evaluation condition and does not depend on the judgment of the design engineer, so that the standard determination of the rough shielding required dimension can be performed.

As described above, the evaluation / determination of the rough shielding required dimension is automatically performed by giving the design condition of the new nuclear facility. Therefore, when the design condition is changed, the re-evaluation or the shield design for the change of the design condition is performed. The effect on the can be easily evaluated.

Further, by using the building plan view data of the new nuclear facility, the position coordinates of the shielding wall and the ceiling, the outline shielding required dimensions can be immediately displayed on the screen together with the building plan view data, for example, in different colors. As a result, it is possible to easily confirm and grasp the evaluated rough shielding required dimension. Further, the display screen can be copied onto paper, OHP, etc. by the image copying apparatus.
