Concept of Multi-function Fusion Reactor

To really use the fusion energy and make the fusion energy as a main energy in the world could need more than 50 years. The construction of ITER starts the real course to realize the peaceful use of the fusion energy. It means the technologies developed in the world are feasible to built fusion facilities or reactors with fusion core plasmas. Based on the technologies nowadays, a concept of multi-function fusion reactor (MFFR) is proposed. MFFR has following functions: fission waste disposal, plutonium 239 breeding from uranium 238, hydrogen producing, tritium producing, components test for fusion reactors, or even electricity power plant demonstration. The preliminary considerations of MFFR are: (a) reasonable configuration and changeable invessel function blanket modules, (b) enough flexibility to realize multi-functions separately or at the same time in the facility, (c) suitable plasma core parameters and blanket concept, (d) fully superconducting toroidal and poloidal magnets. Two major types of functional blankets, sub-critical blanket and energy exchange blanket, are defined in MFFR for transmutation of fission waste/fuel and fusion energy transfer. In this paper, the concept of MFFR and the functional blanket based on the results gained in the past years are introduced.
