A transient experiment due to reactivity- and source-changes was carried out at the Kyoto University Criticality Assembly (KUCA) with the DT accelerator neutron source. To estimate the subcriticality in this source-driven subcritical system, we aim to apply the unscented Kalman filter (UKF) to the time-series data of neutron count measured at KUCA.
