We develop a novel fragmentation model in which the fragmentation cascade is randomly inactivated according to the homogeneous inactivation probability function. For the multiplicative breakup kernel [ital scrF][sub [ital i],][ital j]=([ital ij])[sup [alpha]], we discuss the existence of scaling solutions as [ital t][r arrow][infinity] in different regions of the phase diagram. We also study fluctuations in the cluster-size distribution and find an intermittent behavior in the infinite-cluster phase and at the transition line. Finally, we discuss the relevance of this model for nuclear multifragmentation.
