1. About ITER
ITER (the International Thermonuclear Experimental reactor) was originally proposed at US.-Soviet summit in 1985. ITER design was essentially completed in 2001. During negotiation on December 2003 to pick between two candidate sites, South Korea and the United States supported Rokkasho in northern Japan, whereas Russia and China backed the E.U.’s candidate at Cadarache. After one and half year tense diplomacy and secret discussions, The site at Cadarache, Europe, near Aix-en-Provence, France, has finally been chosen as site for this world’s most expensive science experiment on June 2005.

The overall experimental objective of ITER is to demonstrate the scientific and technological feasibility of fusion energy for peaceful purposes in the shortest possible time and to investigate fusion science
 

ITER is an international project under the auspices of the IAEA involving the European Union, Japan, the United States, Russia, South Korea, China and India. India were welcomed as a full Party to the ITER venture on December 6, 2005. ITER is technically ready to start construction in 2006 and the first plasma operation is expected in 2016.
The host will contribute 50% of the estimated cost of ITER construction, while each non-host will contribute about 10% of the estimated cost of ITER construction. In addition to its share of the construction cost, the host will bear the costs of site preparation.

China has joined the negotiation since Feb, 2003. As a full party member, China will share all benefit from ITER project including design, construction and test operation experiences. China will take on some tasks of ITER project including design and analysis of magnet feeders; design and analysis of blanket modules in the neutral beam port region; design of magnet structures; design of gas injection system and GDC conditioning system, etc.

2. ITER TBM in SWIP
ITER test blanket module (TBM) is an important program. One of its major objectives is to demonstrate the feasibility ofl producing more tritium than it consumes. TBWG (Test Blanket Working Group) is an international working group for TBM program. TBWG have held 16 meetings since 1994. TBWG-16 was held in Beijing, China on November 15-17, 2005. China TBM working group has attended 6 meetings since 2003. The progress and status of HC-SB TBM program in SWIP was presented in TBWG-16.

A TBM concepts are being independently developed in China. Up to now, two concepts for TBM design have been proposed. One of two concepts is CH HC-SB TBM which is in charged by SWIP TBM working group. CH HC-SB TBM design and R&D activities have progressed since 2004. Preliminary design phase have finished. A DDD (Design Description Document: version II) report was completed on November 2005. Detailed design and R&D on related technology of CH HC-SB TBM are on going.
