N2 - In this work we study a stabilization of internal cluster structure of the nuclear system under the fluctuations of the asymmetry value used as a constraint in the shell correction calculations. Persistent cluster magic structures play a main role in origination of various fission modes. We get quantitative results for clustering in theoretical description of actinide multimodal fission by means of analyzing the high dimensional potential energy surface's topological complexity. It is shown that traditional adiabatic description is insufficient in the regions of the deformation characterized by the strong internal shell structures rearrangement and therefore it is necessary to take nonequilibrium effects of reclusterization into account.
