Dependence of scale of ITER type experimental tokamak reactor on H_L factor(the ratio of energy confinement time τ_E necessary for ignition to τ^ITER P_E of L mode scaling), the ratio ξ of magnetic flux of OH coil to the plasma inductance L_pI_p, elongation ratio κ, the distance Δ between the plasma surface and toroidal field(TF)coil conductor and technically possible maximum fields B_t,Mx of TF coil are studied. When the required H_L factor is increased from 2.75 to 3.77 and the distance Δ is decreased from 1.55m to 1.3m in the reference case of ITER design parameters, the major radius R is reduced from R=8.14m to 6.36m, while keeping ξ=1.35. However the decrease of ξ, while keeping H_L constant, is less effective to make device more compact due to the dependence of H_L factor on the parameters. The increase of κ ratio and the increase of the maximum field B_t,Mx is also effective to reduce the scale.
