This paper describes the analysis of operator actions in human reliability assessment for Forsmark 1 and 2 probabilistic safety assessment. The emphasis of the paper is on the used model as well as on its application in estimating human error probabilities. The model is applied for analysis of post-initiating event human actions i.e. actions performed by plant staff after a process disturbance has occurred. The probability of a human error depends on available time and on a number of performance shaping factors. In this approach, a number of experts independently assess performance shaping factors which are combined in a Bayesian manner. Examples are shown as well as the application in Forsmark 1 and 2 PSA is discussed.
