Abstract
Designing and licensing a nuclear power plant and
qualification of its subsystems and components is a
challenging task involving several stakeholders and
integrating information from various disciplines. Several
recent discussions and workshops have shown that the
current practice of justifying safety of nuclear power
plant's systems can be improved. There still seems to be
considerable confusion concerning the key terminology and
the flow of the qualification and licensing processes.
Existing standards and regulations provide limited
guidance on how the licensee should formulate and
communicate a convincing story on the safety of the
facility. All this can be made more systematic and
transparent by utilising the principles of Systems
Engineering and model-based computer tools as the general
framework for both engineering and safety assessment.
There are several analysis methods for collecting the
required evidences for a safety demonstration. These
methods range from plant-level safety architectures to
detailed I&C functions and from technical solutions to
human-machine interactions and safety culture. A
standards-based, structured safety demonstration can be
seen as a knowledge repository that integrates different
disciplines and assessment results into a consistent
overall picture of systems and their safety properties.
