Optimization of spent fuel reduction and reactivity control using LEU+ fuel and hybrid burnable absorbers in innovative small modular reactors

This study presents an advanced core design for the innovative small modular reactor (i-SMR), enabling fully soluble boron-free operation through optimized integration of hybrid burnable absorbers (BAs)—gadolinia (Gd2O3) and erbia (Er2O3)—with LEU + fuel. The design addresses the challenges of exces...
