Major Highlights of U.S. Program ActivitiesRelated to Tokamaks, ITER, ITPA, and Burning Plasmas

since the Last ExCo meetings in June 2004

• DIII-D, C-MOD, and NSTX achieved high utilization of facilities in FY 2004 (ending on 9/30/04)– DIII-D: 18 weeks; C-MOD: 19 weeks; NSTX: 21 weeks

• In FY 2005, the planned levels are 14/17/17• DIII-D completed its FY05 run (15.6 weeks) on 4/15/05;

– Shutdown until April 2006 for hardware improvements;

• C-MOD and NSTX are at their early stages of experimental operations for FY 05.

• Technical reports on their program highlights will be given by Stambaugh, Marmar, and Peng;

• Substantial activity on International Collaborations on all major tokamaks in EU, JA, KO, and CN.


since the Last ExCo meetings in June 2004 (cont)

• Theory support and computer simulations are important elements of the tokamak program;

• Proposals are being solicited for the Fusion Simulation project (FSP), which will unify and accelerate progress on a complete, integrated simulation and modeling capability for ITER class burning plasma;– A part of Scientific Discovery through Advanced Computing, in

cooperation with the Office of Scientific Computing Research– OFES and OSCR will provide ~ $1 M/year each, for five years;

• The U.S. Technology program re-directing some of its activities to support ITER Technology R&D;



• U.S. ITER Project Office started in July 2004, as a joint activity between PPPL and ORNL; – Ned Sauthoff is the USIPO Manager;

• USIPO is preparing for US contributions to ITER:– Approval of ITER as a Project in the U.S. system;– Cost estimates and management plans– Participation in ITER International Team– ITER Physics and Technology Tasks



• The U.S. program continues to be very active in the ITPA, and especially on ITPA/IEA joint experiments;– Full participation in the Oxford planning meeting on

ITPA/IEA experiments, and in Topical Group meetings at Villamoura and Kyoto;

– Substantial accomplishments in DIII-D, C-MOD, and NSTX in carrying out joint experiments;

– Major contributions to the preparation of the Tokamak Physics Basis update of the ITER Physics Basis (December 1999)

• The U.S. will recommend the extension of ITPA for another two years from July 2005



• The U.S. fusion community is establishing a Burning Plasma program (BPP);

• The U.S. activity related to BPP and ITER is extensive: (three facility programs, collaborative experiments, theory & modeling; technology, ITPA);

• A Burning Plasma Program will:– Coordinate activities among related programs;– Focus on ITER needs and plan for physics experiments and

technology tests on ITER;– Advocate for BPP and new scientific staff for ITER;– Integrate U.S. involvement in ITER with the broader

domestic program.

FY 2006 Plans

• FY 2006 is a difficult budget year for the U.S. Fusion Program:– The FY 2006 DOE – Science budget is 1.6 % below that in FY 2005;– OFES budget is up 6.1 % (+ $16.647 M), while most Science programs

decrease– ITER is a top priority project in Science, and it is allocated $ 55.5 M

in the FY 06 Cong. request;– Other OFES programs are reduced to accommodate the ITER budget;

• The facility operating weeks in FY 06 are 5/12/0

– Further details are available in Anne’s presentation to FESAC on April 7/8; (Also the report of the ‘U.S. Priorities Panel’): http://www.ofes.fusion.doe.gov/more_html/FESAC/Presentations4-07-05.html
