Abstract
Probabilistic Safety Assessment (PSA), also called Probabilistic Risk Assessment (PRA), is currently being widely applied to many fields, viz., nuclear facilities, chemical and process plants, aerospace, and even to financial management. PSA has been accepted all over the world as an important tool to assess the safety of a facility and to aid in ranking safety issues by order of importance. PSA essentially aims at identifying the events and their combination(s) that can lead to severe accidents, assessing the probability of occurrence of each combination, and evaluating the consequences. The main benefit of PSA is to provide insights into design, performance, and environmental impacts, including the identification of dominant risk contributors and the comparison of options for reducing risk. PSA provides the quantitative estimate of risk which is useful for comparison of alternatives in different design and engineering areas. Furthermore, PSA is a conceptual and mathematical tool for deriving numerical estimate of risk and quantifying the uncertainties in these estimates.
