Graded approach for initiating event selection in a facility hazard analysis
This paper describes a methodology for selecting initiating events or event scenarios for the hazard analysis of a new Department of Energy (DOE) facility at the Nevada Test Site for nuclear explosive operations called the Device Assembly Facility (DAF). The selection process is a very important first step in conducting the hazard analysis for the facility, which in turn may feed into a quantitative risk analysis. A comprehensive risk analysis is dependent on the identification and inclusion of a complete set of initiating events in the analysis model. A systematic and logical method of grading or screening all the potential initiating events satisfies the needs for completeness within the bounds of efficiency and practicality. By applying the graded approach to the selection of the initiating events, the task and hazard analysis was able to focus its attention on only those events having the potential to develop into credible accident scenarios. Resources were concentrated into the understanding of those scenarios, and assuring that adequate positive measures are in place to control the risk associated with them.
