MICBURN-CASMO analysis of fuel with advanced gadolinia design
Today, the calculation of fuel containing gadolinia as a burnable absorber is routine for both boiling water reactors (BWRs) and pressurized water reactors (PWRs). Over 10 yr of experience with gadolinium in BWRs and several years of gadolinium usage in PWRs have demonstrated the adequacy of the MICBURN-CASMO model. The physics model in the original MICBURN version has been found to be accurate and is still applicable. However, new features for advanced designs like annular gadolinium pellets and gray gadolinium rods have been developed based on the original theoretical model, and the application of few-group cross sections in core calculations have been significantly improved by the usage of flux discontinuity factors in the nodal codes.
