N2 - The grading of quality assurance (QA) controls at nuclear power plant
aims at assuring an acceptable safety level but also at allocating QA
resources cost-effectively. Historically, QA requirements stem from the
safety classification of the systems, structures and components based on
deterministic safety criteria. Risk-informed approaches applying the
probabilistic safety assessment (PSA) are considered as one solution to
rationalise and potentially relax the QA system. In this paper, risk-based
conditions are formulated for the assignment of QA grades. The risk-based
formulation is a reference model to explore possibilities, requirements and
obstacles of this application of PSA.
