The critical site-percolation concentration, as a function of mean coordination, is determined by a Monte Carlo method for the dense-random-packed hard-sphere Bernal model. The results are compared with predictions for regular packing of spheres and for a computer-simulated random packing. It is concluded that the critical site-percolation concentration is not influenced by the structural disorder.
