Plant Information Models

Nuclear Power Plants (NPPs) use multiple information systems and databases from different vendors and for different purposes. Most of these systems are not integrated with each other and cannot share plant data throughout its life cycle. This results in redundancies in capturing, handling, transferring, maintaining and preserving plant’s data. Interoperability problems can stem from the fragmented nature of the industry, paper based business practices, a lack of standardization, and inconsistent technology adoption among stakeholders. Recent exponential growth in computer, network, and wireless capabilities, coupled with more powerful software applications, has made it possible to apply information technologies in all phases of a facility life cycle, creating the potential for streamlining historically fragmented operations.

New NPPs are being designed, procured, and constructed using modern Computer-Aided Engineering (CAE) and Computer-Aided Design (CAD) systems with multidimensional modelling along with data, databases, and electronic document sources. This computer technology forms a computer-based information-modelling environment called the ‘Virtual Power Plant’. As a result, new NPPs will be designed and delivered with a Virtual Power Plant that is comprehensive, detailed and able to be integrated and interoperable with plant design, operations, and maintenance processes, as well as databases, document systems, and records systems of organizations that own and operate them.

These Virtual Power Plant environments typically consist of one or more plant information models. An industry-wide standard plant information model (PIM) could be leveraged as a modern and efficient data-centric approach to better support, manage and transfer design knowledge throughout the nuclear power plant life cycle.

These advanced computer technologies provide an opportunity to radically improve knowledge capture, integration and seamless transfer between stakeholders if industry-wide standards are developed and widely used.
