"Bill Gates and China partner on world-first nuclear technology"

This story slipped under the radar but may be important.
Plus, we've been following it for a decade and aren't quitters.
(I know, it's a fine line between perseverance and pig-headedness) 

From the Sydney Morning Herald, Nov. 7:
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
TerraPower chairman Bill Gates and Chinese premier Li Keqiang signed a joint venture agreement to create the Global Innovation Nuclear Energy Technology company, which will build a Travelling Wave Reactor and commercialise the technology.

This joint venture aims to design and construct multiple nuclear power plants generating around 1150 megawatts over the next two decades which utilise this fourth generation nuclear technology.  
It expands a joint technology agreement between the two businesses signed in 2015.

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

Travelling Wave Reactors would require less fuel per kilowatt-hour of electricity than light-water reactors, due to TWRs higher fuel burn, energy density, and thermal efficiency.

It is also safer as spent fuels, such as depleted uranium, from other reactor types could be recycled without separating out plutonium, and could operate without refuelling for up to 40 years.

TerraPower states that the US currently holds approximately 700,000 tonnes of depleted uranium, and the reactor would only need eight tonnes of this material to power 2.5 million homes for a year....MUCH MORE
