Waste Package Misload Probability

The objective of this calculation is to calculate the probability of occurrence for fuel assembly (FA) misloads (i.e., FA placed in the wrong location) and FA damage during FA movements. The scope of this calculation is provided by the information obtained from the Framatome ANP 2001a report. The first step in this calculation is to categorize each fuel-handling event that occurred at nuclear power plants. The different categories are based on FAs being damaged or misloaded. The next step is to determine the total number of FAs involved in the event. Using the information, a probability of occurrence will be calculated for FA misload and FA damage events. This calculation is an expression of preliminary work performed by Framatome ANP 2001a. This calculation is associated with engineering activity and has been developed in accordance with technical work plan, "Technical Work Plan for: Waste Package Design Description for LA" (BSC 2001). The development of this calculation has been performed in accordance with AP 3.12Q, Revision 0, ICN 4, Calculations.
