【 摘 要 】

The surface harmonics method (SHM) is one of the approaches to neutronic reactor computation reasoning and developing method of homogenization. The symmetry of cells in the method of homogenization and in the SHM is still being used while equations deriving. The cells can be asymmetric in reality. The surface harmonics method allows us to obtain finite-difference equations for a heterogeneous reactor and for the reactor core with asymmetric cells. This allows one to check SHM recommendations on choosing boundaries of the unit cells of the reactor. The examples of test tasks with asymmetric cells are shown in this paper for substantiation of the unit cells boundaries choice for the reactor core.
