Abstract
This paper presents benchmark calculation results for the neutronics parameters of the Kyoto University Critical Assembly with an accelerator-driven system, such as core reactivity, reaction rates of indium wires, and reaction rates of activation foils installed to obtain a neutron spectrum. A developed MCNP model with the ENDF/B-VII.1library represents the details of all core configurations and components according to the benchmark specification. The MCNP results show good agreements with the measured data within 10% of errors. The reaction rates distribution of indium wire and the reaction rates of activation foils compares well with the measured values.
