For the purpose of estimating the reactivity of a subcritical system based on the power profile in a quasi-steady state after a reactivity insertion, a new method has been developed. By applying a linear equation obtained from the multiple integral equation of power in quasi-steady state to the data simulating neutron count rate, it was fined that the data length of moving average was reasonably determined.
