Criticality prediction accuracy for Thorium loaded critical cores constructed at KUCA has been verified. In this study, variety of critical core configurations achieved during the critical experiments of Thorium loaded cores were also analyzed together with the 10 reference critical configurations. The latest critical core having hard neutron spectrum is also included in the analysis.
