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?
