Abstract

This paper shows a sample study where quantitative risk assessment of a tank containing a toxic substance was performed through IDDA method. A comparison is shown between the results obtained through IDDA analysis and the one obtained with classical QRA techniques (Recursive Operability Analysis and quantified Fault Tree directly extracted from it).

The IDDA method provides a full representation of the plant states during operations (ordinary, incidental or irregular operating conditions), as well as all the possible occurrences patterns (description of events), expressed in a set of mutually self-excluding sequences. Availability of the full set of alternative allows the complete spectrum of possible probability-consequence conditions to be used as a basis for decisions in risk reduction and control.
