Sensitivity Analyses of Parameters in an Accelerator Driven Minor Actinide Burner System

Sensitivity analyses of coolant, subcriticality, fuel assembly geometry and thermal power for accelerator driven systems（ADS） are carried out using a home-developed steady-state core analysis code named LAVENDER. The numerical results show that the optimization based on single design target（e.g. beam current, minor actinide transmutation rate or thermohydraulic safety margin） may lead to the deterioration of other design targets and trade-offs should be made to balance the different design targets during the design of ADS.
