  We consider the thermal conductivity, shear viscosity, and momentum
relaxation rates in the nucleon cores of the neutron stars. We study how the
choice of the nuclear interaction and the model for three-body forces may
affect these transport coefficients calculated within the
Brueckner-Hartree-Fock many-body nuclear theory. We find that at relatively
large densities the model dependence of the results is substantial. In addition
we provide the analytical approximations which allow to incorporate our results
in practical simulations.
