Standardized exchange of plant equipment and materials data based on ISO 15926 methodology in nuclear power plants

In a nuclear power plant, classification is a key tool to manage equipment and materials. There could be different classifications corresponding to the different lifecycle phases and the challenge is to achieve and maintain interoperability, continuity, traceability between them. Therefore, it is important to define the equipment and materials classification based on standardized information models in order to effectively share and integrate lifecycle data of equipment and materials. To accomplish this, a method for standardized exchange of plant equipment and materials data based on ISO 15926 methodology in nuclear power plants is suggested. In the proposed method, we use an information model to expand the equipment and materials classification used for the operation and maintenance phase of a nuclear power plant. This is based on the ISO 15926 standard after analyzing the master data from the Shin Kori unit 1 and 2 of Korea Hydro & Nuclear Power Co., Ltd. (KHNP). Furthermore, as a data exchange tool in the proposed method, this study develops a method to exchange equipment and materials specification data by using iRINGTools.
