Description

We have investigated main neutronic parameters and core performance parameters of the reference China Initiated Accelerator Driven System (CiADS) core after loading uranium nitride instead of uranium oxide. Based on neutronic calculations performed with the Serpent code, only 15.2% enrichment is needed to provide similar sub-criticality as the reference design when using UN instead of oxide fuel. Moreover, if we applied the same enrichment level as the one in the reference design, the core size can be reduced by 25%, which eventually permits around 30% higher spallation source efficiency.
