  By the way, in this embodiment and each modification, the arrangement | positioning map information I mentioned above may be the panoramic image inside the nuclear power generation equipment 100 based on the image obtained by imaging the inside of the nuclear power generation equipment 100. The panoramic image is created by the following procedure, for example.

  FIG. 16 is a flowchart of a procedure for creating a panoramic image. In creating a panoramic image inside the nuclear power generation facility 100, first, the inside of the nuclear power generation facility 100 is photographed (step S101). In this case, a panoramic photograph is taken. A panoramic photograph is a photograph with a viewing angle of 360 degrees. When taking a panoramic photograph, marking is performed at a specific position inside the nuclear power generation facility 100. Next, the inside of the nuclear power generation facility 100 is measured (step S102). In addition, the order of step S101 and step S102 is not ask | required.

  The measurement in step S102 is performed on the subject of panoramic photography, for example, 3D laser measurement. For example, the distance between the 3D laser measurement device and the internal equipment of the nuclear power generation facility 100 is measured by scanning the laser beam of the 3D laser measurement device 360 degrees around a predetermined position inside the nuclear power generation facility 100. In this case, a specific position inside the nuclear power generation facility 100 is marked. That is, the inside of the nuclear power generation facility 100 is in the same state as when a panoramic photograph is taken.

  Next, a panoramic image is created by associating the panoramic photograph taken in step S101 with the position information inside the nuclear power generation facility 100 obtained by the measurement in step S102 (step S103). In this case, the panoramic photograph and the position information are associated with each other while collating the marking photographed on the panoramic photograph with the marking measured by the 3D laser measurement. This association is realized by image processing of a computer, for example. The above-described panoramic image creation operation is performed, for example, when the nuclear power generation facility 100 is constructed or during periodic inspection.

  The panorama image created in this way is described, for example, as the layout map information I in the layout map database 4A described above, and is stored in the storage unit 4 of the work plan support apparatus 1 shown in FIG. 1 (step S104). . Further, the position of the simplified FIG. 10 (see FIG. 2) corresponding to the panoramic image is associated with the panoramic image. In this case, when the operator designates the simplified diagram 10, the control unit 3 of the work plan support apparatus 1 displays a panoramic image at that position on the screen 5 </ b> D of the image display device 5.

  As described above, in the work plan support apparatus 1 of the present embodiment and each modification, the layout information I includes a panoramic image based on an image obtained by imaging the inside of the nuclear power facility 100.

  According to this work plan support device 1, by using a panoramic image, if the operator designates a work area in the simplified FIG. 10, the panoramic image at that place can be confirmed. You can check the condition in the reactor containment vessel or the loop chamber at any time. Moreover, since the panoramic image associates the panoramic picture with the measured position, it is easy to observe a desired position of the panoramic image by a computer. Thus, the convenience at the time of grasping the information inside the nuclear power generation facility 100 is improved by using the panoramic image.

  In addition, the work plan support apparatus 1 of this embodiment and each modification can share a shielding plan by connecting the computer 2 to another computer etc. via a communication line. Furthermore, if other computers are of the mobile type, in the above-mentioned work area, the isometric view and panoramic image to which the shielding material is applied can be compared with the actual thing, and the shielding material can be installed. Work and inspection work can be easily performed.

  In addition, the work plan support apparatus 1 of the present embodiment and each modified example is associated with the simplified diagram 10 showing the configuration of the nuclear facility (nuclear facility) 100, and the predetermined work area in the simplified diagram 10 and A layout database 4A having layout information I including the position of each component (piping 11 and equipment 12) constituting the nuclear facility 100; a parts database 4B having design information A including dimensions and materials of each component; A radiation database 4C having radiation information B including the dose equivalent rate and nuclide on the surface of the component.

  According to the work plan support apparatus 1, the above-described layout map database 4A, the parts database 4B, and the radiation database 4C make the simplified diagram 10 a key station, and the isometric diagram 20 associated with the simplified diagram 10, The attribute information (including design information A and radiation information B) of the components of the nuclear power facility 100 can be centrally managed. As a result, it is possible to easily identify the radionuclide, radiation dose, and shape of the radiation source that affect the location where the nuclear facility 100 is to be dismantled and maintained and inspected. Can be created efficiently.
