China Has Officially Joined the ITER Project The end of 2002, China announced to join the ITER Project Negotiation with some Commitments. Oct. 2005, six parties agreed to select Cadarachi as the ITER site. March 2006, Finishing the negotiation for International Agreement. May 2006, Ministers 0f CN, EU, IN, KO, JP, RU, US signing the ITER International Agreement.

ITER Construction Engineering Design (EDA 2001) , Ten years construction. Near 4100 kIAU, 46% by EU, 9% by each of other six parties. Components, cost 2400 KIAU, have been distributed to the seven parties. International Organization headed by DG and PDDG

Within the process of Negotiation Hard negotiation. China satisfy the

final draft of International Agreement. Furious debate inside the Chinese

scientific community, but all MCF people well supported to join ITER project.

Supports by political leaders make this big project to be very special.

Contributions by ChinaProcurement Allocation We need to consider some high-tech packages but more should be matched with our industrial capabilities. Superconductors and related components, Conductor: *NbTi: 67%, 43.8km, 48.57kIUA; *Nb3Sn: 7.5%, 11km, 16.2kIUA;

*Feeder: 100%,26.2kIUA; *Correction Coils:100%, 2.6kIUA

Contributions by ChinaProcurement Allocation

Blancket: *First Wall:10%, 8.7kIUA; *Blancket Shield: 40%, 23.2kIUA.

Power Supply: *High Voltage Station:100%, 21kIUA,*AC-DC Convertors:62%, 51kIUA. Others:*Magnet Supporters:100%, 22.85kIUA, Diagnostics:3.3%, ……total:44.18kIUA Total Contribution by Procurment:241.7kIUA. We have arranged 20Tasks, and will arrange 12 Tasks for preparation.

Contributions by China 10% Manpower in IO will be Chinese, half of them will be directly supported by China as Secondment. We have sent four and will send another four soon. Free Currencies. Scientific Contribution by our two upgraded devices( especially EAST) combining with theoretical and simulation works. ITPA?

Why China Joined ITER Project Energy Demand; Environment Degrade =>

Should emphasize the Fusion Energy R&D It is possible through joining ITER Project to

elevate the Chinese Fusion Research to a new level and ,in the future, to enter DEMO stage simultaneously with other countries.

ITER Project has integrated many high, or new, technologies.

Further open our door in Science and Technology Areas, to a new level.

China Should Has a Perfect Fusion Energy R&D Program.

Joining ITER Project should be, but only, the main part of our Fusion Program, to accelerate our Fusion Research to enter DEMO stage, simultaneously with other advanced countries.

We need, in additional, a domestic program to complement or support the ITER Project, and ask Government to approve it simultaneously.

We need to explain the worldwide and domestic Fusion Energy Programs for Chinese People, especially for Our Scientific Community.

Should be successful to join ITER Project

It is a very hard and special Project in China:It is very big, near ten billion Yuan, high-Tech project.It is very extensive international collaboration, 7

parties with half population of the world.It is unanimously supported by MCF community, but

strongly opposed by some high-top scientists.It was opposed by some political persons but has been supported by high-top political leaders.

We have not to be failure, even to make some significant mistakes.

Should be successful to join ITER Project Ministry of Science and Technology begun to

organize the MCF( or ITER) Center, which has the full power for:As CN DA, Unique for to touch with IO, to arrange the procurement package, sending

people to IO;Arrange the domestic project;Arrange the whole project Budget;S&T Experts Committee of ITER Project;Public Relation.

Should be successful to join ITER Project

Procurement packages: We will sign and arrange 32 tasks with IT and have got financial support by “973 Program”. Now our products, in laboratory scale, all already meet the requirements of ITER Design.

The crucial point is: To send high quality team to IO; To collect and to train up enough many talents,

scientific or engineering, as soon as possible.

Should be successful to join ITER Project

Through different ways to grasp overall knowledge of ITER construction and comprehensive ITER results.

To make further contributions to ITER Project. Such as: high power long-pulsed operation on EAST , numerical simulations ……

To form strong and comprehensive Fusion Scientific and engineering teams.

Domestic Part of our MCF Program

To support up-grading EAST and HL-2A to be able to make contribution to ITER Project: 8MW ICRF and 8MW LHCD to EAST;

Enlarge plasma volume with new Divortor and 6MW NBI for HL-2A . Basic Tokamak Physics , Plasma Physics Education and Training for Fusion Technology.

150MYuan for 5 years.

Domestic Part of our MCF Program Fusion Technologies: such as TBM tech.; plasma heating tech. ; divortor tech. et al. Reactor studies, mainly for DEMO. Reactor material studies: such as first wall, high heat-flux plate, ….., development and testing.

Possible Important Physical Problems for ITER

Burning Tokamak Plasma behaviors: Should be studied experimentally on ITER, but could do some by theoretical and numerical simulations. Reliably to stabilize the plasma tore, it should control the bootstrap current. It is necessary to study the properties of the bootstrap current. and the way to control it

Possible Important Physical Problems for ITER

To study how to realize high power, very long-pulsed discharge in big Superconducting Tokamaks. To study very slow processes in high power, long-pulsed discharge.
