Major Highlights of U.S. Program Activities Related 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.

Major Highlights of U.S. Program Activities Related to Tokamaks, ITER, ITPA, and Burning Plasmas 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;

Major Highlights of U.S. Program Activities Related to Tokamaks, ITER, ITPA, and Burning Plasmas since the Last ExCo meetings in June 2004 (cont) 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

Major Highlights of U.S. Program Activities Related to Tokamaks, ITER, ITPA, and Burning Plasmas since the Last ExCo meetings in June 2004 (cont) 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

Major Highlights of U.S. Program Activities Related to Tokamaks, ITER, ITPA, and Burning Plasmas since the Last ExCo meetings in June 2004 (cont) 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 % (+ $ 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’): 05.html
