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
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
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
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.
