We propose a simple model of extra-dimensional radius stabilization in a SUSY Randall-Sundrum model. In our model, we introduce only a bulk hypermultiplet and source terms (tadpole terms) on each boundary branes. With appropriate choice of model parameters, we find that the radius can be stabilized by SUSY vacuum conditions. Since the radion mass can be much larger than the gravitino mass and even the original SUSY breaking scale, the radius stability is ensured even in the presence of SUSY breaking. We find a parameter region in which unwanted scalar masses induced by quantum corrections through the bulk hypermultiplet and a bulk gravity multiplet are suppressed and the anomaly mediation contribution dominates.
