Abstract.  Two types of two-dimensional codes, i.e. a transport code and a diffusion one, have been developed for analysis of alpha-particle effects in ICF plasmas. On the basis of 2-D coupled transport/hydrodynamic simulations, we investigate the energy and momentum deposition effects of alpha-particles on the Rayleigh-Taylor instability in a stagnating DT planar plasma. After the accuracy validation of the diffusion code, the sensitivity of fuel gain to the perturbation amplitude is also discussed by carrying out 2-D coupled diffusion / hydrodynamic simulations for a DT spherical target with mode number of l = 2 - 12.
