Abstract

Abstract

Adjoint sensitivity analysis（ASA） and the forward sensitivity analysis（FSA） based on the reduced order module（ROM） were developed on the 2D/1D transport code KYCORE. Sensitivity analysis on the TMI-1 PWR cell benchmark was performed. Results show that sensitivity coefficients of the effective multiplication factor（keff） with respect to 235 U fission and capture cross sections calculated by KYCORE and RMC agree well with each other. However, the dependency exists in the resonance region. Sensitivity coefficients calculated by the FSA based on the ROM and the direct numerical perturbation（DNP） are consistent. Therefore, ASA and the FSA based on the ROM developed on the 2D/1D transport code KYCORE are verified.
