  We study radiative corrections to the radion potential in the supersymmetric
``detuned RS model'', with supersymmetry broken by boundary conditions.
Classically, the radion is stabilized in this model, and the 4d theory is
AdS_4. With a few bulk hypermultiplets, the one-loop correction to the
cosmological constant is positive. For small warping, this correction can
(almost) cancel the classical result. The loop expansion is still reliable in
this limit. The graviphoton zero-mode, which controls supersymmetry breaking,
is a modulus of the classical theory, but is stabilized at one-loop. Both
unbroken supersymmetry and maximal supersymmetry breaking are stable
ground-states of the quantum theory.
