In this paper, a pin-by-pin fine mesh core calculation method, which has been used in PWR, is applied to BWR as a candidate of next-generation core calculation method. Results of pin-by-pin fine mesh core calculation, in which fuel cells are homogenized, are compared with those of heterogeneous transport calculation. By applying the pin-by-pin fine mesh calculation with the SPH correction, multiplication factor and pin-wise fission rate distribution obtained by the heterogeneous calculation is accurately reproduced by the cell-homogenized fine-mesh calculation in BWR multi-assemblies geometry.
