Nonlinear density-wave instabilities are analysed for two-phase channel flows with nuclear heating. The fluid is homogeneous and enters the channel at saturated conditions. A Lagrangian formulation is used to re- express the governing equations as an integro-differential system. Asymptotic analyses, based on multiple-scale expansions, are exployed to determine the evolution of velocity perturbations arising in the neighborhood of the linear stability boundary.
