Abstract
We calculate the renormalized quantum vacuum energy-momentum tensor in side a spherical boundary, where the background geometry inside the bo undary is represented by the closed static Friedmann metric. The remor malized energy density has two terms, one of which comes from the loca l curvature and the other one is due to the presence of the boundary. The renormalized energy density has a nonintegrable divergence as the boundary is approached.
