On the basis of coupled transport-hydrodynamic calculations, we investigate the effect of neutron heating on the burn dynamics of ICF pellets. We also evaluate the energy spectrum of neutrons emitted out of a typical burning pellet. Because of rapid pellet expansion, these neutrons contain fast components with energies of more than 20 MeV. Tritium breeding ratio (TBR) is estimated using the realistic neuron energy spectrum for typical D-T laser fusion reactors. It is found that the TBR obtained is smaller by about 5--15% as compared to the case of 14-MeV monochromatic source. [copyright] 1994 [ital American] [ital Institute] [ital of] [ital Physics]
