This document shows that microturbulence can have a direct effect on the evolution of interchange instabilities. A simple, two-fluid model of the Rayleigh-Taylor instability is considered which incorporates the effects of microturbulence through anomalous electron-ion and ion-ion collisions. A set of two-dimensional nonlinear mode coupling equations is developed. It is demonstrated that the intermediate wavelength regime of the instability can saturate by transferring energy from the growing modes to the damped modes because of the nonlinear E x B motion. A crucial point in the analysis is that anomalous electron-ion collisions provide the dissipation mechanism for the damped modes. Applications of this theory to early time HANE(High Altitude Nuclear Event) structuring are discussed.
