Benchmark analysis for accelerator-driven subcritical reactor with pulsed neutron generator in Kyoto University Critical Assembly (KUCA)

► A benchmark analysis of number of experimentations at Kyoto University Critical Assembly (KUCA) is made. ► Simulations were carried out employing state of the art computer code MCNP-5 1.4v with cross-section library ENDF-B-VI-5. ► The maximum error in excess reactivity results is 28% and in Subcriticality results the maximum error is within 23%. ► Proper material guide can raise neutron yield in the core region.
