Coles, G A

This paper describes how using the built-in intelligence of linked fault trees to help identify initiating events can be an important part of a Probabilistic Risk Assessment analysis. It describes how this identification was done on a microcomputer-based application for a reactor Probabilistic Risk Assessment. It discusses results of this application and describes how this technique helped in discovering initiating events that may have been otherwise overlooked. 2 refs.
