The concept of heavy ion fusion power plant (HIFPP) involves fast ignition of cylindrical target by intense heavy ion beam of super-energetic ions — 500 MeV/u. Estimated data on the energy flux delivered to the reactor chamber wall by 600 MJ fusion yield are given. The response of the blanket and of thin liquid film at the first wall surface is evaluated. Lithium-lead eutectic is taken as a coolant. The evaporated mass and the condensation duration are estimated taking into account the major thermo-physical effects. It is concluded that repetition rate of HIFPP cycles can reach up to 2Hz in case of two sections reactor chamber designed. The estimations of neutron spectrum from HIF target have given the average neutron energy of ~11.2 MeV. The mechanical stresses in construction material due to the neutron energy release are evaluated. The outlet reactor chamber temperature is taken 550⁰C. The heat conversion system consisting of three coolant loops provides the thermal efficiency of the HIF power plant of 0.37.
