      The results of computations of k_эф elementary cells of triangular fuel element lattice in reactors WWR-440 AND WWR-1000 obtained using the group method and Monte-Karlo method are given. The influence of the technique of accounting resonance and heterogeneous effects, chemical bond in a coolant and boundary condition selection on the results of group computations is studied.
