  • A study of the conceptual data modeling to realize the decommissioning database on the HRR-1&2 was carried out. In this study, the current state of the abroad decommissioning database was investigated to make a reference of the database. A scope of the construction of decommissioning database has been set up based on user requirements. Then, a theory of the database construction was established and a scheme on the decommissioning information was classified . The facility information, work information, radioactive waste information, and radiological information dealing with the decommissioning database were extracted through interviews with an expert group and also decided upon the system configuration of the decommissioning database. A code which is composed of 17 bit was produced considering the construction, scheme and information. The results of the conceptual data modeling and the classification scheme will be used as basic data to create a prototype design of the decommissioning database.

  • In decommissioning activities of nuclear facilities, the analyses and evaluations of data(man power, radiation exposure, waste outputs, equipments, etc ) is very important to accomplish effective decommissioning and dismantling. To handle the data from decommissioning activities of research reactor, we developed its database system. By using database system, we come to filter and analyze the date of decommissioning activities and we can evaluate the extraordinary decommissioning features of research reactor. It is likely to lay out and estimate the optimal plan of decommissioning. We expect that the database system of effective decommissioning activities build up the foundation of commercial reactor decommissioning.

  • Korea Research Reactor (KRR) 1&2 has shut down and through preparatory activities, its decommissioning activities are underway. As its decommissioning activities have been done over several years, its relevant data have been spreaded with various type and media all over the discrete place and inadvertently managed, As a result, managing and assessing data of KRR 1&2 has been difficult and complex and its data cannot be evaluated. By developing the decommissioning database system of KRR 1&2 the data of decommissioning activities can be correctly evaluated, being systematically managed and objectively assessed. Finally, the decommissioning project of KRR 1&2 have come to more effectively accomplished. As the data of decommissioning activities can be at last systematically analyzed and objectively assessed, the decommissioning project of KRR 1&2 would be more effectively accomplished.

  • ISP (Information Strategy Planning), which is the first step of the whole database development has been studied to manage effectively information and data related to the decommissioning activities of the Korea Research Reactor 1&2(KRR-1&2). In order to establish the scope of the decommissioning DB, user requirement and the importance of the decommissioning information were analyzed and set up the conceptual design of the decommissioning DB and established the classification system related to decommissioning activities. It has been extracted the principle information such as working information facilities information, radioactive waste treatment information and radiological surveying and analysis during the interviewing with an experts. And also, It has been made the code system. These results will be used as the basic data to design the prototyping for the decommissioning DB.

  • It is necessary to forecast the various dismantling activities prior to dismantling nuclear facilities by using various software instead of a physical mock-up system because the dismantling in a contaminated with radioactivity cause the results of an unexpected situation. The component that needs to develop a dismantling mock-up system was examined. There are many component systems such as a decommissioning database system,3D dosimetric mapping that represents a distribution of a radionuclide contamination, a component of modeling for nuclear facility and devices include the decontamination and decommissioning. The research of software architecture about these components was carried out because these component systems that have been independently doesn't describe not only to visual an activities of Decontamination and Decommissioning(D&D) but also to evaluate it. The result was established an architecture that consist of an visualization module which could be visualized an D&D activities and a simulation module which can be evaluated a dismantling schedule and decommissioning cost.
