Electron conduction losses due to magnetic flutter produced by resistive interchange instabilities and the resulting confinement deterioration mechanism are investigated analytically. Using approximate solutions of MHD equations for even and odd potential parities, the potential and magnetic perturbation levels at saturation are estimated. These results are used to calculate the stochastic magnetic field diffusion coefficients. An expression for the anomalous electron thermal conductivity is then derived for collision-less and collisional regimes. Scaling laws for energy confinement are inferred therefrom.
