Bill Gates' nuclear firm TerraPower and the China National Nuclear Corporation have signed an agreement to develop a world-first nuclear reactor, using other nuclear reactors' waste. Fourth generation Travelling Wave Reactors would differ from third generation, more traditional light water nuclear reactors, as they?would?not require enriched uranium to generate energy, and could?instead use waste uranium. The Australian Nuclear Science and Technology Organisation (ANSTO) is part of the Generation IV International Forum Framework which they call ?a potential game-changer in global energy creation". http://www.smh.com.au/business/energy/bill-gates-and-china-partner-on-worldfirst-nuclear-technology-20171106-gzfrf0
