To realize the COP21 decision, this paper proposes Inter Renewal Travelling Wave Reactor that bear high burn-up rate 50% and product TRU fuel efficiently. This reactor is based on 4S Fast Reactor and has Rotary Fuel Columns as fuel assemblies (Fig.1, Fig.2, Fig.3) that equalize temperature in the fuel assembly so that fewer structure is need to restrain thermal transformation. To equalize burn-up rate of all fuel assemblies in the reactor, each rotary fuel column has each motor-lifter. (Fig.3) The rotary fuel column has two types (Cylinder type & Heat Pipe type using natrum at 15kPa which supply high temperature energy for Ultra Super Critical power plant). At 4 years cycle all rotary fuel columns of the reactor are renewed by the metallurgy method (vacuum re-smelting ) and TRU fuel is gotten from the waste fuel. (Fig.4)
