  3. 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.

  4. 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

  5. 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.

  6. 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

  7. 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.

  8. 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?

  9. 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.

  10. 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.

  11. 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.

  12. 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.

  13. 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.

  14. 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.

  15. 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.

  16. 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.

  17. 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

  18. 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.
