Advanced Nuclear Fuels Corporation (ANF) first introduced gadolinia integral burnable absorbers in pressurized water reactors (PWRs) a decade ago. The experience of ANF with gadolinia burnable absorbers include nearly 45,000 gadolinia-bearing fuel rods in {approx}7500 assemblies irradiated in 29 reactors: 11 PWRs and 18 boiling water reactors. Predictable neutronic performance and excellent fuel integrity has been achieved by ANF in its supply of gadolinia-bearing fuel for light water reactors. A key benefit of gadolinia as a burnable poison is the broad flexibility it offers to fine-tune core power distributions as function of cycle burnup yielding, for example, maximum low-leakage fuel management benefits without exceeding licensed limits.
