Keywords:SHIKOKU2, ASMOC3D, Linear Source, Weighted Residual Method

SHIKOKU2 uses ASMOC3D as a transport calculation model. Previous ASMOC3D approximated the radial distribution of neutron source in the mesh to be flat. In this study, we improve ASMOC3D to expand that with a first-order polynomial. We perform core analysis using SHIKOKU2 after the model improvement, and we confirmed that the analysis accuracy is improved.
