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)
Tasks 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;
Working scheduleof the National MFR Integration Design Group
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?
