Casks used for transporting radioactive material need to be certified fit by subjecting them to a specific set of tests (IAEA, 2012). The high cost of these casks gives rise to the need for optimizing them. Conducting actual experiments for the process of design iterations is very costly. This work out lines a procedure for optimizing Type B(U) casks through simulations of the 9m drop test conducted in ABAQUS^®. Standard designs and material properties were chosen, thus making the process as realistic as reason able even at the cost of reducing the options (design variables) available for optimization. The results, repeated for different source cavity sizes, show as cope for 6.9% reduction in cost and 4.6% reduction in weight over currently used casks.
