In recent 10 years, a number of conceptual design studies of Inertial Confinement Fusion (ICF) reactors have been carried out to examine the engineering feasibility and to find technological problems. Typical types of ICF reactor are reviewed in section 2, including the guidance to the new current. The characteristics of the ICF plasma core are described in section 3. Renewable liquid wall is employed in the waterfall or wet wall ICF reactor. The features of liquid wall/blanket are shown in section 4. Finally the technological problems to be studied are discussed in section 5.
