Abstract
[Solving Means] A resonance calculation program is configured to calculate an effective cross section including Step Sof setting a calculation point in the gray range in the resonance region; Step Sof calculating a neutron flux set at the calculation point and corresponding to a macroscopic cross section based on Method of Characteristics; Step Sof fitting a fitting equation to the calculated macroscopic cross section and the calculated neutron flux, and calculating first and second rational coefficients; Step Sof calculating a background cross section based on the first rational coefficient; Step Sof interpolating the effective cross section, with the background cross section used as an argument; Step Sof calculating the neutron flux based on the background cross section; and Step Sof calculating the effective cross section based on the effective cross section, the neutron flux, and the second rational coefficient obtained at the coefficient calculation step.
