An integrated advanced scenario of tokamak formation without the use of an Ohmic heating (OH) solenoid in the JT-60U tokamak was investigated. The OH solenoid was not used but the electron cyclotron, lower hybrid waves, neutral beam injection and the loop voltage provided both the poloidal flux and vertical field. The plasma generated from this scenario had both internal and edge transport barriers with an energy confinement of 1.6 times H-mode scaling, poloidal beta of 3.6 and large bootstrap current fraction. The results show improved economic competitiveness of tokamak reactor without the use of OH solenoid.
