A reference model for the NPP I&C qualification process and safety demonstration data

This report presents a qualification process example and safety demonstration data metamodel we suggest to be used in qualification of I&C systems, equipment and components of nuclear power plants. By utilising such model-based systems engineering approach in assuring the safety of complex I&C systems, the engineering and conformity assessment effort can be managed more rigorously, yet with better agility due to possibility of automatic generation of documents. The systematic process and data models help identify gaps in fulfilling the process and product safety requirement. Applicability of the safety demonstration data metamodel is demonstrated by a simple case example.
