The effective chiral mean-field model of Furnstahl, Serot and Tang (FST) is proposed to examine stability of superheavy nuclei. The FST model is an example of a nuclear effective field theory where the hadronic Lagrangian is constructed according to the symmetries of quantum chromodynamics and the ``naturalness'' condition.
