Abstract
IE is not only the important content in (PRA）, but also is the foundation of PRA. Analyzing the IE includes: identification, screening and grouping, however, there is no scientific method for screening IE. Therefore, a method for screening IE based on the improved Borda ranking method has been proposed. Firstly, we apply the Borda ranking method to make up the deficiency of the risk evaluation index. Also, combining with the characteristics of IE, which is the beginning of the event chains, we improved the Borda ranking method.Secondly, taking the Filling system as the research object, we analyze the portion IE causing the propellant leak, and apply the improved method to rank and screen IE. Lastly, comparing the results of improved method with index and traditional Borda method, also combining the actual engineering situation in filling system, we validate the correctness and effectiveness of the improved method.
