Critical Experiment Analyses by CHAPLET-3D Code in Two- and Three-Dimensional Core Models

A series of critical experiments has been analyzed by the deterministic method code CHAPLET-3D in two- and three-dimensional core configurations in which explicit core structures are represented. The results show that the three-dimensional core calculation model employed in CHAPLET-3D code is valid and useful to obtain fine resolution results by the deterministic method. Moreover, the conventional two-dimensional axial buckling calculation for critical experiment analysis has also been validated, through the comparison between the results of two- and three-dimensional experimental core analyses by CHAPLET-3D code.
