In this paper a new method for numerical modelling of the tide-generated currents, the thermal and nuclear pollution in aquatic environments of the nuclear plant is presented. This method is a hybrid scheme of fractional steps on irregular triangular grids, in which an upwind discretization or a modified characteristics procedure is used for convection operator, the lumping finite element technique is used for diffusion operator with a "source" term and a conservative difference scheme for surface elevation calculation. L∞-stability, simplicity and flexibility in handling complex geometries have made this method applicable to predict the thermal pollution of planned nuclear plants.
