We design a volumetric neutron source based on a steady-state tokamak device with super-conducting coils. It is found that the neutron flux of 1 MW/m2 is available in the medium-sized device (R = 4.5m, a = 1.0 m, κ = 1.8 and Ip = 5.6 (MA) under the conditions of H = 2 and βN = 3 with a NBI power of 60 MW. We demonstrate the controllability of the current profiles required for high beta plasma up to βN = 3 with the combination of the bootstrap current and NB-driven current. The Li-Pb blanket is adopted with water-cooled and austenitic stainless steel-structured system. The calculated local TBR reaches 1.4 or more in Li-Pb breeder at a sufficient thickness of breeding zone. The net TBR might be available only with the outboard Li-Pb blanket.
