Abstract

The present invention relates to a cutting process simulation method and a system thereof which can efficiently optimize the decommissioning process of a nuclear facility, thereby saving costs and time and ensuring safety in the decommissioning process. The cutting process simulation system, according to one embodiment of the present invention, may comprise: a display unit: and a control unit which cuts a cutting target in a nuclear facility by using a design program, displays the cut shape on the display unit, and predicts the amount of secondary waste generated in the process of cutting the cutting target.

First claim

The invention claimed is:

1. A cutting process simulation system comprising:
a display that displays a product; and
a controller that cuts the product corresponding to a facility in a nuclear plant by using a CAD (computer-aided design) kernel and API (application programming interface) functions and that represents a cut geometry on the display, and
wherein the controller is configured to:
create the cut geometry for cutting the product into a solid model by using cutting tools and a cutting trajectory;
represent the cut geometry with a thickness and depth by performing a remove operation on the product according to the cut geometry;
save the cut geometry as a CAD file by using a topological geometry with no specification history; and
estimate an amount of secondary waste generated from the process of cutting the product in a unit of mass,
wherein the controller calculates volume of geometry of an intersection between the product and the cut geometry by performing an intersect operation on the product and the cut geometry, and estimates the amount of secondary waste generated by multiplying the calculated volume and density of the product; and
by setting a type of secondary waste differently according to one or more components included in the cut geometry;
an amount of sawdust is estimated as the amount of secondary waste when the cut geometry comprises wood; and
an amount of metal pieces is estimated as the amount of secondary waste when the cut geometry comprises metal.

2. The cutting process simulation system of claim 1 , wherein, if there is an overlap between the product and the cut geometry, the controller determines that cutting has been done, and if there is no overlap between the product and the cut geometry, the controller determines that no cutting has been done.

3. The cutting process simulation system of claim 1 , wherein the controller cuts the product repeatedly.

4. A cutting process simulation method comprising:
displaying a product on a display;
cutting the product corresponding to a facility in a nuclear plant by using a CAD (computer-aided design) kernel and API (application programming interface) functions; and
representing a cut geometry on the display,
wherein the cutting process simulation method further comprises:
creating the cut geometry for cutting the product into a solid model by using cutting tools and a cutting trajectory;
representing the cut geometry with a thickness and depth by performing a remove operation on the product according to the cut geometry;
saving the cut geometry as a CAD file by using a topological geometry with no specification history; and
estimating an amount of secondary waste generated from the process of cutting the product in a unit of mass,
wherein calculating volume of geometry of an intersection between the product and the cut geometry by performing an intersect operation on the product and the cut geometry, and estimating the amount of secondary waste generated by multiplying the calculated volume and density of the product; and
by setting a type of secondary waste differently according to one or more components included in the cut geometry;
an amount of sawdust is estimated as the amount of secondary waste when the cut geometry comprises wood; and
an amount of metal pieces is estimated as the amount of secondary waste when the cut geometry comprises metal.

5. The cutting process simulation method of claim 4 , further comprising:
if there is an overlap between the product and the cut geometry, determining that cutting has been done; and
if there is no overlap between the product and the cut geometry, determining that no cutting has been done.

6. The cutting process simulation system of claim 1 , wherein the controller represents cases where the product is cut, where the product is cut but cannot be cut, where the product is cut into two parts, and where the product is cut into three or more parts.
