[2G16] Study on inverse kinetic method without explicitly using neutron generation time

*Tomohiro Endo1, Kenichi Watanabe2, Manobu Tanaka3 (1. Nagoya Univ., 2. Kyushu Univ., 3. KEK)

Keywords:inverse kinetics method, reactivity, neutron generation time, simplest reactivity estimator, median filter

In order to robustly estimate the reactivity using the inverse kinetics method in a case where the neutron generation time for the target system has a large uncertainty and the outliers in the input signal of neutron counts are exists, the following studies are investigated: (1) improvement of the “Simplest Reactivity Estimator (SRE)” without explicitly using the neutron generation time, and (2) the application of the median filter to the input signal.
