We start the preparatory tasks for decommissioning with two sub-tasks of the investigation for plant characteristics and the radiological characterization, which we collectively call the plant characterization. Sub-tasks in the downstream of the tasks refer and utilize the results from the plant characterization. Because the results from the plant characterization are 'facts of the plant,' only the reliability of the results can make the decommissioning plan effective and efficient in safe. And how easy to access the results affects the work efficiency of the decommissioning planning. To achieve both correctness and efficiency in the decommissioning plan, we have been developing an appropriate data structure of the results from the plant characterization. And we have also been developing the data interface between each sub-tasks. In this presentation, we will present the detailed data structure and data interface utilized in the tasks.
