Reaction rate distribution of Kyoto University Critical Assembly ADSR experiment is analyzed in a subcritical system combined with a 14-MeV pulsed neutron source. A comparison between the experimental results of the reaction rate distribution using optical fiber detectors and the calculation results using MCNPX code is performed. Neutron multiplication of the subcritical core is measured and analyzed utilizing the reaction rate distribution.
