If China is able to achieve the 75 gigawatt target for 2020 then it would seem that the 2030 target would be about 200 gigawatts.  In 2007, nuclear power in China provided 62.86 billion kWh - 2.3% of total, and there is now 8.6 GWe (net) installed. 

Using the same capacity factors as China currently has the 75 GWe for 2020 would achieve 548 billion kWh.  The USA was able to achieve 806 billion kwh from 101 GWe using 91.8% utilization.  If China was able to achieve that level of utilization then 75 GWe would produce 598 billion kWh. 

If China in 2030 was able to achieve its 250 GWe target that would be more than double the current USA nuclear power and achieving over 2000 billion kWh.  This would be over 1500 billion kWh higher than the high projection from the IEA for 2030. 

The IEA projections for Russia are also far lower than what Russia is planning to build. 

China, Russia, India, Brazil and South Korea seem likely to have far higher nuclear reactor build than the IEA projection. 

Also, there is the possibility that success with uranium hydride Hyperion Power Generation, China's plan for factory mass produced High Temperature Pebble reactors or IEC nuclear fusion would vastly increase the amount of power from nuclear energy. 

Non-OECD Asia leads the world in installing new nuclear capacity in the IEO2009 reference case, accounting for 54 percent of the projected net increment in nuclear capacity worldwide (or 72 gigawatts of the total 132-gigawatt increase).  China, in particular, has expansive plans for nuclear power, with a net 47 gigawatts of additional capacity projected to be installed by 2030.  Currently, 11 nuclear power plants are under construction in China, including 6 for which construction wasstarted in 2008. [ International Atomic Energy Association is the March 2009 source fir EIAWith generation from coal, natural gas, and renewable energy sources also expected to continue increasing rapidly, however, the nuclear share of total generation in China increases only from 2 percent in 2006 to 5 percent in 2030.
