An advanced tokamak transmutation system is proposed as an alternative application of fusion energy based on a review of the previous studies. This system includes: (1) a low aspect ratio tokamak as fusion neutron driver, (2) a Radioactivity Clean Nuclear Power System (RCNPS) as blanket, (3) a novel concept of liquid metal center conductor post (CCP) as part of toroidal field coils. A preliminary feasibility study has been carried out for the system, which included the aspects of core plasma physics, blanket neutronics and design. A driver of 100MW fusion power under 1MW/m neutron wall loading can transmute the amount of High Level Waste (including minor actinides and fission products) produced by 10 standard pressurized water reactors of 1 GW electrical power output. Meanwhile, the system can produce tritium and output about 2 GW of electrical energy. After 30 years of operation , the biological hazard potential (BHP) level of the whole system will decrease by 2 orders of magnitude.
