Future Energy Demand in China

• Population will step up inevitably from present
  1.2 billion to at least 1.6 billion in 2050
• China will grow up to be a moderate developed
  country in 2050
• Annual Energy Consumption per person will
  increase from near 1 TCE to no less than 3 TCE (
  at present time, US 11.5 TCE West Europe 5.6
  TCE Japan 5.1 TCE)
• Estimated Energy Demand increasing from near 1B
  TCE to over 4B TCE within next 3-4 decades.

Future Options

• To realize the long-term sustainable
  development, it is necessary for China to explore
  reliable ways and develop thousands of GW non-
  fossil fuel power.
• Hydro-power was developed quickly during past 5
  years.
• To build hundreds of GW Fission Nuclear Power
  Plants in China - social problems, safety and
  environmental concerns, technical difficulties
  should be solved in near future. There are 6
  nuclear plants( total 8.7GW) now.
• We have arranged many renewable-energy and
  hydrogen energy programs, but is too small scale.
  
• Therefore, it is crucial and urgent for China to
  realize the controlled Nuclear Fusion Energy for
  our long-term development in the future as early
  and fast as possible.

The reasons for China to join ITER
ASIPP

• Fusion has a long and successful history of
  international collaboration with obvious benefits
  to all partners for peaceful purpose.
• The technology and cost of ITER is beyond our
  ability if china would like build such kind
  machine at moment.
• By joining ITER, we can share the knowledge
  involved in ITER and take a more aggressive step,
  saving both development time and budget.
• Promoting the domestic fusion related industries
  and training the young scientists and engineers.

6
Chinas commitment to ITER
ASIPP

• China believes that ITER can potentially lead to
  new forms of energy and contribute to the
  peaceful and sustainable development of the world
  in the long-term. 
• China expressed its strong commitment to be a
  valuable member of the ITER family, to make joint
  efforts with other partners to the successful
  exploitation of fusion energy.
• By Joining ITER together with fast development of
  domestic MFE program, China should have solid
  base for design and construction DEMO around
  2020.

7
What we need for this goal?
ASIPP

• Good domestic MCF program and MFE stratagem
  planning. 
• Full knowledge of ITER construction and
  operation.
• Key RD for DEMO technology.
• Solid bases for theory and simulation.
• Enough young scientists and engineers.
• Good industry support.
• Strong support from government and public.
