Very Strong Support with Questions from Top Leaders and Public Why China joint ITER ? What is the next step and goals of fusion research in China ? ITER in China Contribution by in kind Domestic sub-project for: Improving the basic conditions; Development for key tech. Fusion materials; Theory and education; Reactor intergration design. Total is 0.6 billion US dollars ~ 0.6 billion US dollars Budget for ITER-CN (10 years) China MFR integration design group has been founded Members of the MFR integration design group Wan,Yuanxi USTC, ASIPP Wu, Songtao ITER Li, Jiangang ASIPP Li, Qiang SWIP Liu, Yong SWIP Weng, Pede ITER, ASIPP Wang, Xiaolin CAEP Guo, Huoyang USA Ye, Minyou USTC Feng, Kaiming SWIP Wan, Baonan ASIPP Wan, Farong BUST Duan, Xuerun SWIP Fu, Pen ASIPP Yu, Qin quang Germany Wu,Yican USTC, ASIPP Zhuang, Ge HUST Gong, Jun INS Yang, Qinwei SWIP Tasks of the National MFR Integration Design Group Now - 2014: providing two options of engineering concept design of CFETR which should include in: • Missions • Type • Main physics basis • Main technique basis to be taken • The concept engineering design for all sub-systems • Important R&D items • Budget & Schedule and Location • Management system 2015: proposal to government to try to get permission for construction; (because the preliminary first proposal has been ranked No.1 in the national next 5Y plan—started at 2016) Working schedule of the National MFR Integration Design Group Within next 6 months: the mission, type and main physic, technic & engineering basis for one option of CFETR should be determined The second option also should be determined preliminarily From medial of this year the activities of the conceptual desing both on physics and engineering will be started It is hoped that at around end of 2014 or ealy of 2015 the engineering conceptual desing of CFETR can be completed. The proposal for constructon of CFETR should be sent to government to try to get permission at 2015; About this workshops Mission: It is a series of workshops; It is expected that the workshops will give us the advisory suggestion, opinion, comments or proposals for next step of MFE development in China; The two design options will be determined by our design group finally after two or three workshops and series of internal expert meetings within next six months from now. About this workshops Topic-1: Suggestion or advisory opinion on what the mission and strategy of MFE development in China should or could be. Topic-2: Tokamaks option • Types (AT, ST, Hybrid?) • The basis of physics can or should be taken. • The basis of technologies can or should be taken. • Challenges and risks Topic-3: Alternative options • Stellarator ? Types The basis of physics can or should be taken. The basis of technologies can or should be taken. Challenges and risks • Any Other attractive options? Under discussion final option ?
