英文摘要：

Embedded self-shielding method（ESSM ） is a combination of equivalence theory and one-step transport calculation on lattice, which generates the resonance self-shielding cross section. ESSM uses a transport solver （e. g. MOC） to perform the fixed source calculation iteratively for treatment of self-shielding effect. ESSM is also capable of treating resonance interference effect by generating the library for nuclide mixture. Numerical results show that ESSM evaluates the resonance interference effect well and achieves higher accuracy and efficiency compared to other resonance calculation methods.
