A system code for designing helical fusion reactors have been developed. A radial build of a helical reactor is considered in the code, and three-dimensional effect of each type helical reactors is reflected by including detail analysis result of them in other study. Sensitivity analysis have held by using the code so as to clarify the physics and engineering issues needed to be solved to design high performance helical fusion reactor. Here we tried to design two types of helical reactors; i.e., an ignition machine and a commercial reactor. If we design an ignition machine with a major radius of 8〜10m, the improvement of the energy confinement factor of H_<ISS>=2.5〜3 might be required. In the commercial helical reactor a high-density/low-temperature operation regime (e.g., n_e〜6×10^<20>m^<-3>, T_c;, T_e=8keV) is feasible by improving confinement (H_<ISS>=2) and by increasing maximum magnetic field strength (B_<max>=20T), while it is not accessible in tokamak reactors due to the limitations of the Greenwenwald density and the current drive power.
