Excess reactivity control using innovative burnable absorber configuration for a 24-month cycle APR-1400

Extending the fuel cycle from 18 to 24 months in Pressurized Water Reactors (PWRs) using LEU+ fuel (5 % ≤ U-235 ≤ 10 %) increases excess reactivity, requiring effective control to ensure safety and performance. This study evaluates various BA concepts—including gadolinia or erbia homogeneously mixed...
