When a waste device is cut into waste device pieces, when, in what order, and to what degree of particle size the cutting process is provided is important. In other words, depending on what kind of cutting line is provided on the waste equipment, the period required for cutting, the amount of the waste equipment fragments resulting from cutting, etc. are determined. Patent Literature 4 describes, as a criterion for determining whether the cutting process is good or bad, "to reduce the number of waste storage containers in the entire plant".

Here, unlike ordinary dismantling work, dismantling work of waste equipment contaminated with radioactive substances has special circumstances regarding radioactivity. For example, as waste storage containers for storing waste device fragments, a high-level container for high-level radioactivity and a low-level container for low-level radioactivity contain the same capacity of waste device fragments. However, the cost is overwhelmingly higher for high-level containers. For example, high-level vessels use thick shell plates to limit radiation leakage outside the vessel, or dig hundreds of meters below ground to store high-level vessels underground. And the cost will be higher.

Furthermore, due to social demand, there is a demand for shortening the work period until the dismantling work is completed. In this way, there are various criteria for determining the quality of a dismantling work plan for waste equipment, and it is extremely difficult to formulate an appropriate dismantling plan that satisfies these criteria in a well-balanced manner.

Accordingly, the main object of the present invention is to appropriately support demolition plans for facilities such as plants contaminated with radioactive substances.

In order to solve the above problems, the waste disposal apparatus of the present invention has the following features.

The plurality of dismantling starts calculated by the radioactivity distribution calculation unit, wherein the shape data with cutting lines in which cutting lines for cutting the waste equipment into waste equipment pieces are set in the shape model data of the waste equipment. a cutting line generation unit that generates for each candidate time point ;
Regarding the waste storage containers for storing the respective waste equipment fragments cut according to the shape data with cutting lines, high-level containers and low-level containers are separately filled according to the radioactivity concentration of the radioactivity distribution. a container model generation unit that generates container model data for each of the plurality of dismantling start point candidates ;
a calculation control unit for displaying the container model data and an evaluation index for the container model data for each of the plurality of dismantling start time candidates on a waste amount evaluation screen ;
The cutting line generation unit includes a first cutting line setting rule for the waste equipment piece to be filled in the high-level container, and a second cutting line setting rule for the waste equipment piece to be filled in the low-level container. The line setting rule is set by rules different from each other.
Other means will be described later.

As with the process specification screen 2100, the administrator presses a start date button 2402 and an end date button 2404 to specify a date from the calendar. Here, for example, January 1, 2020 (2403) is set as the start date, and December 31, 2030 is set as the end date (2405).

By pressing a read button 2431, the administrator can read out from the evaluation result storage database 110 a cumulative curve 2441 showing the chronological change in the number of high-level containers and the generation rate of waste storage containers. 2442 can be confirmed.
In addition, the waste amount evaluation screen 2400 includes not only the number of high-level containers but also data at the time of completion of dismantling (in other words, the earlier the dismantling is completed, the higher the evaluation index) as an evaluation index for each process. may be displayed.

FIG. 8 is a flow chart showing processing of the total waste amount management device.
As S101, the calculation control device 30 executes the following loop of S102 to S115 for each process for process data set in the decommissioning process database 70 or process data read from the decommissioning process database 70.
As S102, the calculation control device 30 determines whether or not there is an unprocessed process. If Yes in S102, one process is selected from the unprocessed processes as a processing target of the dismantling/cutting simulation, and the process proceeds to S111. If No, the process proceeds to S121.

As S<b>111 , the input device 10 reads the data content of the residual radioactivity database 90 .
As S112, the radioactivity distribution calculation device 40, based on the residual radioactivity database 90 read in S111, the 3D distribution ( radioactivity distribution). This radioactivity distribution is corrected by calculating the half-life as appropriate according to the period data read from the decommissioning process database 70 (details are shown in FIGS. 14 and 15).
The radioactivity distribution calculation device 40 corrects the theoretical value of the radioactivity inventory read from the residual radioactivity database 90 with the measured value obtained by measuring the on-site dose of the waste equipment, thereby calculating the radioactivity on the waste equipment. A distribution may be calculated.

As S113, the cutting line generation device 50 refers to the cutting variables in the cutting variable storage unit 120, generates a cutting model according to the radioactivity distribution of the waste equipment calculated in S112, and attaches the generation result to the cutting line. 3D data 130 is assumed.
As S114, the container model generation device 60 generates a container stuffing model for storing the waste equipment fragments cut along the cutting line of the 3D data with cutting line 130 of S113 in the waste storage container, and the generation result is is stored in the storage container type storage database 100 . Here, in the container packing model, the waste storage containers for storing the waste equipment fragments are divided into high-level containers and low-level containers shown in FIG. be.

At S115, the calculation control device 30 refers to the storage container type storage database 100, evaluates the plant dismantling process including the process of cutting the waste equipment into waste equipment pieces, and stores the evaluation results in the evaluation result storage database. 110. The evaluation criteria for the plant dismantling process here include space cost (the smaller the number of waste storage containers, the higher the evaluation) and time cost (the earlier the dismantling end point, the higher the evaluation).
As described above, S111 to S115 are the process evaluation process for one process, and the process returns to S102 in order to shift to the evaluation process for the next process.

As S121, after completing the evaluation of each process, the calculation control device 30 displays the waste amount evaluation screen 2400 to allow the manager to compare the processes. As a result, for example, the manager can adopt (process 3) as a representative plan among (process 1) to (process 4), which can reduce both the space cost and the time cost in a well-balanced manner. can make decisions.

FIG. 9 is a three-dimensional diagram showing a 3D model stored in the 3D model database 80. As shown in FIG. The 3D model 80a is the 3D shape of the highly contaminated or highly radioactive waste equipment.
FIG. 10 is a table showing attribute data of a 3D model 80a stored in the 3D model database 80. As shown in FIG. By storing the equipment number, dimensions, weight, material, radioactivity data, and dismantling method as attributes in the 3D model database 80 in association with the 3D model 80a, it is possible to search from the equipment number and process data. to facilitate collaboration.

FIG. 11 is a table showing residual radioactivity data stored in the residual radioactivity database 90. As shown in FIG. In the residual radioactivity database 90, the system, the equipment (number), the weight, the amount of activation (each of H3, Be10, Co60) for each nuclide, and the amount of contamination are associated with each building of the plant. ing. Activation and contamination are expressed in units of Bq/t.

FIG. 12 is a table showing storage container type data stored in the storage container type storage database 100. As shown in FIG. In the storage container type storage database 100, for each type of waste storage container (L1 = high level container, L2-1a = low level container), the radioactivity concentration range, the waste storage container and the waste stored therein The weight limit, container size, material, filling rate, etc. of the waste equipment piece are stored.

FIG. 13 is a three-dimensional diagram of the 3D data 130 with cutting lines. The cutting line generation device 50 is used for the 3D model 80a of FIG. When obtained, a cutting line is generated in the 3D model 80a, and a model cut to dimensions that can be stored in a waste container is generated.
For example, in FIG. 13, there is a highly activated portion in the center of the cylinder in the height direction (a portion where the radioactivity concentration exceeds a predetermined threshold), and there are low activated portions at the upper and lower ends in the height direction. (the part where the radioactivity concentration is below the predetermined threshold).

The cutting line generation device 50 generates a cutting line so that the highly activated portion is cut into fine (small) waste device pieces 132 (first cutting line setting rule). On the other hand, the cutting line generation device 50 generates cutting lines so that the low-activation portion is cut into coarse (large) waste device pieces 131 and 133 (second cutting line setting rule).
As a result, the waste equipment pieces 132 are finely crushed, so that when they are stored in the high-level container, they are buried without gaps, so that the filling rate can be increased. As a result, the number of filled high level containers can be saved.

FIG. 14 is a plan view showing 3D data 130 with cutting lines in 2020. FIG. Here, it is assumed that the radioactivity distribution calculator 40 outputs a radioactivity distribution 311 that is larger in the center as the radioactivity distribution in 2020.
The cutting line generation device 50 refers to the radioactivity distribution 311, and when creating the 3D data 130 with cutting lines from the waste equipment in the 3D model database 80, the range passing through the radioactivity distribution 311 (horizontal range 312, vertical In the range 313), the cutting lines shown by dashed lines are set densely, and the cutting lines are set loosely in the range that does not pass through the radioactivity distribution 311. FIG. As a result, the number of high-level containers to be filled can be saved as in the case described with reference to FIG.

Also, the low level container contains coarse (large) waste equipment pieces. Therefore, the filling rate of the low-level container is lower than the filling rate of the high-level container. However, in general, even if the number of low-level containers is slightly increased, the storage cost is less than for high-level containers. On the other hand, in the process of cutting into coarse (large) waste equipment pieces, the cutting work is simplified, so that the work period and the risk of radiation exposure during work can be reduced.

FIG. 15 is a plan view showing 3D data with cutting lines 130 in 2025 five years after the state of FIG. Here, it is assumed that the radioactivity distribution calculation device 40 outputs a radioactivity distribution 321 smaller in the center as the radioactivity distribution in 2020. This is because the radioactivity distribution naturally decreased (halved) over the five-year period from 2020 to 2025.
14, the cutting line generation device 50 sets the cutting line densely in the range (horizontal range 322, vertical range 323) passing through the radioactivity distribution 321, and the range not passing through the other radioactivity distribution 321 set the cutting line coarsely.

This further reduces the number of high level waste equipment pieces compared to the case of FIG. 14, thus further saving the number of high level containers to be filled. If there is an upper limit to the number of high-level containers due to circumstances such as difficulty in securing a final disposal site, the cutting line generation device 50 delays the dismantling start point in this way before calculating future cutting lines. You may

As a result, an appropriate cutting line can be presented in consideration of the radioactivity concentration for the dismantling plan regarding the amount of high-level radioactive waste. Therefore, it is possible to reduce the number of high-level containers and shorten the cutting work period.
