In this paper, we investigate the saturation physics in diffractive deep inelastic electron-ion scattering. We estimate the energy and nuclear dependence of the ratio σdiff/σtot and predict the xℙ and β behavior of the nuclear diffractive structure function F2,A D(3)(Q2,β,xℙ). Moreover, we analyze the ratio Rdiff A1,A2(Q2,β,xℙ)=F2,A1 D(3)/F2,A2 D(3), which probes the nuclear dependence of the structure of the pomeron. We show that saturation physics predicts that approximately 37% of the events observed at eRHIC should be diffractive.
