Presented at APEX / ITER-TBM Meeting
November 3 – 5, 2003
UCLA, Los Angeles, CA
TBWG-11, Garching, October 22 – 24, 2003
• TBWG (Test Blanket Working Group) manages the ITER Test Blanket Program.
It is a joint activity, conducted by the Parties and the Central Team. The Chair is
drawn from the Parties, and the Co-Chair from the Central Team.
• TBWG was reconstituted in July 2003. The newly reconstituted TBWG met in
Garching (TBWG-11) October 22-24, 2003.
- Chair: Luciano Giancarli (EU, CEA)
- Co-Chair: Valeriy Chuyanov (ITER Garching, RF)
- There are 3 members from each Party. One member from each Party is
designated as the Senior Representative.
- The US members of TBWG are M. Abdou, D. Sze, and M.Ulrickson.
- Attendance of experts at TBWG meetings is allowed with prior permission
of the Chair. Alice Ying attended TBWG-11 as a US expert.
General Remarks about TBWG-11
• Participants were all delighted that ITER is regaining momentum and there are
three new parties: US, Korea, and China.
• The US major contributions to the ITER Test Program since early CDA (and,
even earlier, INTOR) were clearly recognized. (The US is widely acknowledged
as a primary “intellectual power” in fusion testing (many US studies in the 80’s
and 90’s: FINESSE, VNS, etc.)
• The number of ports in ITER have been reduced to three, but the number of
parties has increased to six.
• The US made many suggestions on strategy for the meaningful testing on ITER,
stronger collaboration among the Parties on R&D and construction of TBM’s,
etc.. These suggestions were well received.
• TBWG Plans, Port Allocation to Concepts, and Formation of Working Groups for
various blanket concepts were among the accomplishments of TBWG-11.
• The next meeting (TBWG-12) will take place March 9 – 13, 2004 in Japan.
What should DDDs include?
A-
For each blanket line, several TBM’s will be tested in sequence (see “test
program” proposals).
B-
Most TBM associated systems (i.e., all systems that cannot be installed
behind the ports, such as coolant systems for He-cooled TBM) have to be
designed in connection with ITER Teams from the beginning.
C-
The DDD’s should describe at least two port configurations:
- the configuration with TBM’s and associated systems to be installed on
Day 1
- the most demanding configuration of TBM’s and systems (performance
tests with complete integrated TBM?) with all parts designated for the
envelope case [required for defining space allocation in ITER buildings,
feeding pipes, test cell requirements, …]
D - What to do when data are unknown?
Use the method chosen by ITER project: complete DDD’s with the best of all
required parts and indicate unknown data as TBD (useful for identifying
most urgent R&D/design work).
