Highest Priority US ITER Physics Tasks

• 1) RWM control in ITER Steady State Scenarios
• Benchmarking of codes used for simulation of RWM
  feedback control on ITER scenario 4 plasmas.
• Study of ITER RWM control with in-vessel coils.
• Specification on noise in sensors used for RWM
  control.
• 2) VDE, Disruptions and their mitigation in ITER
• Validation of the codes in experiments,
  simulation of disruptions in Scenario 2, effect
  of blanket modules, 3D halo currents, impurity
  generation / transport / radiation loss for the
  assessment of beta drop during VDEs, simulation
  of high-pressure noble gas jet penetration into
  Scenario 2 plasma, design requirements to the
  ITER system of disruption mitigation, evaluation
  of the effects of radiation produced by gas
  injection on the first wall and diagnostic
  system.
• Model development of halo current width during
  VDEs based on experiments
• Simulations of VDEs in ITER with 3D MHD code
• Disruption mitigation by noble gas injection
• Determine if a jet of noble gas can penetrate
  deeply into high pressure plasma
• 3) Evaluation of Fast Particle Confinement of
  ITER
• Evaluation of the effect of fishbone
  oscillations, TAE modes and toroidal ripple on
  the fast particle loss
• 4) Assess the effects of radiation transfer on
  the ITER divertor solution
• Assess the physics in current codes to properly
  predict the effects of opacity and radiation
  transfer on divertor plasma solutions for ITER
• 5) Benchmarking of ICRF codes on ITER plasma and
  antenna

Near-term US ITER Project Activities

• Addressing areas of risk in provisional US
  in-kind contributions
• Performing RD and design work in areas of US
  in-kind contributions
• in partnership with the VLT
• with ITER-Direct funding for industrial
  procurements, etc.
• Focus on high-risk near-term issues, such as
  magnet RD and design
• Working with DOE to establish an effective
  Burning Plasma Diagnostic RD and Design
  Activity
• Preparing project management aspects
• Exhibit 300 is being reviewed by OMB
• CD-0 Mission Need Statement is being reviewed
  within DOE
• CD-1 preparation is underway, targeting
  completion in Spring 2005
• Cost range
• Conceptual design
• Preliminary Project Execution Plan
• Acquisition Strategy
• CD-2 will entail a disciplined Preliminary Design
  Review and Cost Estimate, leading to
  establishment of the cost, schedule and
  performance baseline in Fall 2005 - Winter 2005-6
