The Kyoto University Critical Assembly (KUCA) experiments were launched in 2000 at the Kyoto University Research Reactor Institute (KURRI) with the main objective to establish measurement techniques of neutronic parameters in subcritical systems and to investigate the accuracy of the neutronic design of an Accelerator Driven Subcritical Reactor (ADSR). Due to the continuing interest in nonproliferation issues, new studies are being performed on these assemblies with the purpose to investigate the feasibility of converting the KUCA cores to the use of low-enriched uranium (LEU) fuel. The KUCA facility consists of the solid-moderated and -reflected type-A and -B cores, and the water moderated and -reflected type-C core. The present document describes the analysis carried out at Argonne National Laboratory (Argonne) on the KUCA type-A cores. In particular, calculated results of the KUCA ADSR benchmark assemblies and of the feasibility studies on the conversion of the KUCA dry cores from highly-enriched uranium (HEU) to LEU are presented.
