ADS experiments are carried out with the combined use of lead-loaded core and external neutron source (14 MeV or spallation neutron) at KUCA, in order to measure the ratio of kinetics parameters (βeff/Λ). The dependence of subcriticality and the external neutron source is investigated on βeff/Λ through the comparison between experiments and calculations.
