A Probabilistic Safety Analysis of UF6 Handling at The Portsmouth Gaseous Diffusion Plant
- Safety and Reliability Optimization Services (SAROS), Inc., Knoxville, TN (United States)
A probabilistic safety study of UF6 handling activities at the Portsmouth Gaseous Diffusion Plant has recently been completed. The analysis provides a unique perspective on the safety of UF6 handling activities. The estimated release frequencies provide an understanding of current risks, and the examination of individual contributors yields a ranking of important plant features and operations. Aside from the probabilistic results, however, there is an even more important benefit derived from a systematic modeling of all operations. The integrated approach employed in the analysis allows the interrelationships among the equipment and the required operations to be explored in depth. This paper summarizes the methods used in the study and provides an overview of some of the technical insights that were obtained. Specific areas of possible improvement in operations are described.
