In order to improve data accuracy of neutron-capture and total cross sections of minor actinides and long-lived fission products, the time-of-flight experimental instrument named "Accurate Neutron-Nucleus Reaction measurement Instrument (ANNRI)" was constructed and neutron time-of-flight experiments have been performed with intense pulsed-neutron beam at MLF in J-PARC. In the experiments in ANNRI, the results include not only the statistical uncertainty but also the uncertainty due to each analysis step. In this presentation, detailed information about the deduced uncertainties will be reported.
