Probabilistic and deterministic safety assessment and standards: Goals and judgment (some examples)

At first the broad situation is analyzed with regard to the use - in safety analysis and the licensing process and decisions to be made - of probabilistic risk or safety assessment. The development of quantified objectives is noted, highlighting these can be quite different in nature and in status; the various types of objectives are illustrated. Because of the relation of the Seminar to the SMiRT-Conference, as a practical specific example of respective deterministic and probabilistic approaches, an application in structural mechanics is described: criteria for the resistance of the primary boundary against various types of degradation and loadings.
