Pennsylvania State University presently processes approximately 415 Pathfinder fuel elements which will require shipment from their nuclear facility. Criticality safety calculations have been performed with the Monte Carlo code, KENO-IV, and 16-group Hansen-Roach cross sections for shipment of these fuel elements in Model No. RA-3 shipping containers. Except for a slightly higher U-235 enrichment in the UO sub 2 rods of the Pathfinder fuel elements, the parameters for the proposed shipment are within those limits currently approved in Certificate of Compliance No. 4986, Revision No. 17, for shipment of UO sub 2 fuel rods in the Model RA-3 shipping containers. The analysis in this report verifies an adequate margin of criticality safety for the Pathfinder fuel elements in Model RA-3 containers for a Fissile Class 1 shipment. (ERA citation 12:015398)
